Yemen is responsible for the first officially documented use of coffee. In a 15th-century monastery of Sufis, a group of Muslim mystics documented roasting and brewing coffee to stay alert during rituals.

Coffee first arrived in the Middle East from Africa in the 15th century. It quickly became one of the most popular beverages in city centers like Cairo.

Coffee then spread to South India, Persia, Turkey, and North Africa after seeds were smuggled to Mysore, India, by a Sufi. Prior to this event, all coffee seeds traded on the open market were sterilized and would not grow. 

Botanically, What are 7 Facts About Coffee You Didn't Know?

Here are seven fun facts about coffee plants.

  1. Coffee isn't a bean but a seed from inside a fruit or “cherry.” The outer covering is called ”cascara” and usually turns from yellow to orange to red, but different varieties ripen to orange or yellow.

What is Special About Coffee?

Coffee is more than just a beverage. It’s a deeply embedded part of our lives with rich cultural and economic significance. It has built empires, played a role in wars and revolutions, sustained the Industrial Revolution, and shaped the modern coffee culture.

What are 10 Surprising Facts About Coffee Culturally and Politically?

Coffee has cultural and political significance, and below are some coffee fun facts about it.

  1. Coffee was an integral part of the Ottoman Empire’s economy that they parboiled the coffee beans before shipping them from Mocha to the rest of the world [20]. This rendered the beans infertile, allowing the empire to maintain a monopoly on coffee and preventing other countries from cultivating and producing coffee.
  2. The Ottoman Sultan banned coffee houses, thinking that they breed radical ideas detrimental to the empire. The bans started in 1623 and lasted until 1839, but despite the bans, coffeehouses continued to pop up [61].
  3. There was a time when coffee was banned in Prussia (now Russia, Germany, and Poland) and France. Prussia banned coffee in 1781 and encouraged the people to drink beer instead. In 1806, the French substituted chicory root for coffee when France cut off trade with Britain which, unfortunately, included the coffee trade [20].
  4. Coffee helped the slave trade flourish. European nations enslaved several Asian, Caribbean, Central American, and African countries, forcing people to work on their coffee, sugar, tobacco, and cotton plantations [78].
  5. Culturally, coffee houses became places where people gathered to discuss not just the news but politics and religion as well. They also became places for debates and, yes, breeding grounds for revolutionary and radical ideas [78].
  6. Coffee's popularity in the United States boomed after a revolt against the British on December 16, 1773. The event, called the Boston Tea Party, took place at Griffin's Wharf in Boston, Massachusetts. American colonists, frustrated and angry at Britain for imposing "taxation without representation," dumped 342 chests of British tea into the Boston Harbor. 
  7. Coffee sustained the 18th Century’s Industrial Revolution. It kept factories running by keeping the workers awake [78].
  8. Coffee fueled wars and is one of the essentials in combat rations. The Ottoman soldiers left sacks of coffee when they failed to invade Vienna in 1683 [37]. Coffee sustained our World War I soldiers, and during World War II, officials rationed the coffee of civilians so the soldiers wouldn’t run out of supply [78].
  9. Coffee houses, since ancient times, were not just places to get coffee but social hubs where people gather. But in the mid-1980s, Starbucks revolutionized the whole coffee culture. Coffee was no longer just a companion to good conversation but became an experience in itself. Quality beans, skilled baristas, and exceptional service became front and center of the coffee culture.
  10. The 1980s also sparked the Third Wave Movement in coffee. From mass-marketed coffees, consumer preference shifted to specialty and single-origin coffee. Interest and support for fair trade coffee also increased.

What are Some Facts About Coffee Brewing Methods?

Call out text box showing the different types of brewing methods.

In the 1930s, coffee grounds were put in a cap with boiling water poured overtop. This is still done in some parts of the world, like the Middle East, where it is called ”Mud coffee.” In the United States, this is called ”cowboy coffee.”

Starting in the 16th century in the Ottoman Empire, very fine ground coffee was placed in a special pot ('cezve’ in Turkish) and boiled and removed from heat several times. The potent brew — called Turkish Coffee — is served in small cups, often with cardamom.

The French Press was first patented in 1852 (then called the ”cafetière” in French). This classic method of brewing can take some practice to get grinding (a coarse grind) and timing right (4-7 minutes). A tall container with a plunger separates the ground from the water when the brew is finished.

Drip Coffee, Sometimes called filtered coffee, uses hot water that drips slowly over coffee grounds contained by a special filter. It was the most common method for brewing coffee in North America but has gradually fallen out of favor towards more specialty brewing methods like pour-over and espresso. 

The first paper coffee filters were invented in 1908.

The Japanese have been making cold brew coffee for centuries. Cold water is poured over the grounds and allowed to steep for 8 to 24 hours.

The Moka Pot was patented in 1933 in Italy. It uses a specially designed stovetop pot that forces hot water up through a puck of coffee to create a brew resembling espresso.

The AeroPress is a recent innovation in coffee brewing that was invented in 2004. It combines immersion and pressure brewing philosophies to create an espresso-like coffee.

Instant Coffee was invented in the 50s. It's made by brewing a large vat of coffee, which is then spray-dried or freeze-dried to preserve its flavor.

Pour Overcoffee is brewed by manually pouring water over fresh-ground coffee. The extraction is then filtered through paper or metal screens using devices like the Chemex or Hario V60.

The Hario V60 gets its name from the ideal 60-degree angle of the cone. It's believed to offer the ideal extraction rate as water flows through the grounds and into your cup.

Coffee brewing times that are too long extract heavier, more bitter compounds. Long brew times produce an overpowering bitterness. Brew times that are too short create a watery brew.

A professional coffee taster is called a “cupper.”

Cuppers are trained to examine five key characteristics when tasting coffee: 

  • Acidity: A snappy, sharp taste that can be desirable or overwhelming. (Not the Ph of a coffee)
  • Aroma: Smell can bring out flavors the tongue cannot taste. There are hundreds of coffee aromatics, some examples being floral, citrus, chocolate, and caramel.
  • Body: Can be described as ”mouth feel” or ”weight.” It’s how the coffee feels inside the mouth.
  • Bitterness: In moderation, bitterness isn’t negative because it contributes to a balanced flavor profile. However, when it overpowers other notes, it becomes undesirable.
  • Aftertaste: After the coffee has left the mouth, flavors and aromas linger. This is also called “finish.”

Expert baristas emphasize the use of uniform ground in all forms of preparation, regardless of brewing method.

Three espresso cups showing under, perfect, and over-extraction with times under 30s, 20–30s, and over 30s.

Adding dairy (or non-dairy alternatives) changes the mouth feel of coffee. It’s used to suppress bitter or acrid flavors and aromas.

The most prestigious barista school in the world is the Universita del Caffe, founded in Trieste, Italy, in 1999.

What are the Different Types of Coffee in the Market?

There’s no exact number when it comes to the different types of coffee. However, we can split them based on basic coffee drinks, milk-based coffee drinks, cold coffee drinks, flavored coffee drinks, alcoholic coffee drinks, and regional coffee drinks.

Basic coffee drinks are mostly black coffee with no additives like cream or sugar. These include your regular brew, espresso, Americano, long black, lungo, and decaf.

Milk-based coffee drinks contain additives like sugar and cream. These include espresso-based coffees like latte, cappuccino, macchiato, flat white, mocha, caffe breve.

Cold coffee drinks are pretty straightforward! These include any coffee type with cold water or ice such as cold brew, regular iced coffee, Vietnamese iced coffee, frappuccino, and Dalgona coffee.

Flavored coffee are coffee drinks with special flavors like pumpkin spice, peppermint, hazelnut, caramel, and chocolate.

Alcoholic coffee is any coffee mixed with alcohol. Good examples include espresso martini and Irish coffee.

Lastly, there are the regional coffees or coffee drinks specific to a country. There’s Africa’s Cafe Touba, Indonesia’s Kopi Luwak, Vietnam’s Cà Phê Trứng or egg coffee, the Philippines’ Kapeng Barako, Cuba’s Cafecito, Hawaii’s Kona coffee, Turkey’s Turkish coffee, to name a few.

What Exactly is an Espresso?

Espresso is the most common method for professional coffee brewing. It requires a specialized machine that forces pressurized hot water through a puck of finely ground coffee.

Espresso is made using a 1:1 ratio of coffee and water (traditionally about 30 mL).

The word espresso has several meanings, such as “expressing” a flavor or being fast like an ”'express” train. The foam on top of an espresso is called “crema” and adds unique flavors. (See for yourself by removing the crema from your espresso and taste testing.)

The first espresso machine was patented by Angelo Moriondo in Italy.

What are the Different Types of Espresso?

Call out text box showing the different types of espresso-based drinks.

Here’s a quick coffee fact about espresso — it can serve as base for different types of coffee drinks!

  • Cappuccinos are made using single or double shots of espresso (30-60 mL) with frothed milk. The ratio of milk foam, liquid milk, and coffee is 1:1:1.
  • Lattes are made using two shots of espresso mixed with milk at a 1:3 ratio (120 mL).
  • Macchiatos traditionally use just one shot of espresso — about 30 mL with a small amount of foam on top. Macchiato means ”mark” in Italian, from when baristas used to mark different shots.
  • Cortados contain a single shot of espresso with an equal amount of milk and some foam (60 mL).
  • Flat Whites are made using one or two shots of espresso (30-60 mL) mixed with microfoam.
  • There’s also an espresso-based drink called Dirty Coffee. It consists of 4 oz to 6 oz of cold milk with one shot of espresso.
Why is It Called Dirty Coffee?

Dirty Coffee is made by pouring espresso over cold milk. The drink is named Dirty Coffee because of the way espresso “stains” the cold milk as the liquids slowly mix together.

The FDA recommends that we consume no more than 400 mg of caffeine per day [85]. But for some people, this amount can cause anxiety. Taking more than 200 mg of caffeine in one sitting can also trigger side effects [52].

How Much Caffeine is Too Much?

Consuming more than 400 mg of caffeine in a day can lead to overconsumption. Caffeine also becomes toxic at a dose of 1.2 grams, and over 10 to 14 grams could be fatal. This usually occurs from taking caffeine pills, not chugging espresso [29].

How Long Does Caffeine Take to Work?

All caffeine will be absorbed by the digestive system after oral consumption within 45 minutes [76]. But you can feel its effects start working in about 15 minutes, with bloodstream levels peaking an hour after consumption [99]. The effects can last for several hours.

Timeline chart showing caffeine intake, from consumption to building caffeine tolerance.

How Long Does Caffeine Stay in Your System?

Half of the caffeine you’ve consumed stays in your system six hours after consumption. In some people, it could take up to 10 hours for their systems to completely get rid of the caffeine [99].

Some drugs also change how long caffeine's effects last, extending effects by using liver enzymes [65].

When Does Caffeine Tolerance Start?

Caffeine tolerance can build up rapidly, taking effect within a single week. The more caffeine you consume, the faster you develop tolerance.

How to Get Caffeine Out of Your System?

The best way to get caffeine out of your system is to simply wait it out. Drinking plenty of fluids, eating fiber-rich foods, and exercising may also help speed up the process. Of course, you also need to stop consuming more caffeinated beverages and foods so they don’t add more caffeine to what’s still in your system.

What Does Caffeine Do to Your Body?

Caffeine has good and bad effects on the body. It’s a stimulant and, at low to moderate doses, can boost brain functions. You feel more energized, alert, awake, and focused [64]. It also helps with weight loss since it acts as an appetite suppressant and metabolism booster [80,89]. 

Call out text box showing the positive and negative effects of caffeine.

However, at high doses, caffeine produces negative effects. It makes you feel jittery, anxious, restless, and dizzy. It could also trigger headaches, a fast heart rate, and higher-than-normal blood pressure. Caffeine increases gastric acid levels, which can upset your stomach or worsen your heartburn symptoms [80].

Of note, genetic factors appear to influence caffeine's effects and may be inherited from one generation to the next [21]. 

Can Caffeine Make You Tired?

Yes, caffeine can actually make you feel more tired when it starts wearing off, and adenosine has something to do with it.

Adenosine is a type of brain chemical that makes us feel sleepy. The more sleep we lose, the more adenosine the body produces. Now, caffeine prevents adenosine from binding to its receptors. With no receptors to bind to, we feel more energized, awake, and alert. But as the effects of caffeine wear off, the rush of adenosine binding to the receptors makes us feel tired and sleepy [88].

What are the Caffeine Side Effects to Watch Out for?

Some of the caffeine side effects to watch out for include:

  • Jitteriness and shakiness
  • Increased anxiety
  • Very fast heartbeat and palpitations
  • Nausea and vomiting
  • Headaches
  • Increased sweating
  • Cardiac arrest (at very high doses)

Is Coffee Actually Healthy for You?

It’s a mix of both, but in general, coffee is healthy for most people. We’ll discuss these coffee facts below.

Is Coffee Healthy or Unhealthy?

Low to moderate consumption (no more than 400 mg of caffeine) is generally safe and healthy for most adults. However, consuming more than the recommended daily limit can produce side effects and may even worsen some health conditions.

What Do Scientists Say About Coffee?

 Attitudes towards coffee have flip-flopped over the years. Today, science supports the opinion that coffee is a health beverage — when used in moderation.

A study conducted in Spain showed that when folks stopped drinking coffee after being regular consumers, their health declined [67].

Why is Coffee Good or Bad?

Coffee is a major source of dietary antioxidants. Green coffee, in particular, contains over 1000 antioxidants.

Research has shown coffee contains many bioactive and beneficial compounds:

  • Polyphenols: Polyphenols have been implicated in preventing heart disease, diabetes, and cancer while showing potential neuroprotective properties, treatment of COVID-19, and improved fertility [54].
  • Chlorogenic Acids: Also a huge factor in flavor, chlorogenic acids have antiviral, antibacterial, anticancer, and anti-inflammatory effects while reducing the risk of cardiovascular diseases, type 2 diabetes, and Alzheimer’s [77].
  • Cafestol: Cafestol may help prevent cancer, inflammation, and diabetes [72].
  • Trigonelline: Making up 1% to 3% of dry weight of coffee, trigonelline has neuroprotective and antidiabetic effects [4].
  • Melanoidins: Melanoidins have been studied for antimicrobial and anticancer properties alongside effects on inflammation and hypertension [63].
  • Hydrocinnamic Acids: Hydroxycinnamic acids may be very beneficial to people with Parkinson's disease [56].

While it depends on many factors like the type of bean, where it was grown, and how it was roasted and prepared, the nutrients one cup of coffee contains are roughly [8]: 

  • Magnesium: 7 mg (2% of the DV)
  • Potassium: 115 mg (3% of the DV)
  • Niacin (B3): 0.5 mg (3% of the DV)
  • Riboflavin (B2): 0.2 mg (11% of the DV)
  • Total Calories: 2–5 

A cup of coffee also typically has around 62 mg to 120 mg of caffeine. While caffeine has its own health benefits, it can trigger side effects at very high doses. 

Does Coffee Have Fiber?

Yes, coffee contains a small amount of fiber, with each 100 mL having around 0.47 g to 0.75 g of fiber [26]. It’s definitely not enough to meet the recommended dietary fiber intake of 25 g to 30 g daily [42]. But if you’re drinking four cups of coffee daily, then you’d be consuming around 5.8 g of fiber daily, each 8-oz cup having an average fiber content of 1.45 g. This makes you 21% closer to the recommended dietary fiber intake.

What are the 10 Benefits of Coffee?

Here are 10 health benefits of coffee:

  • Alertness: Coffee enhances mental performance but can also cause insomnia [27]. 
  • Pain: Caffeine enhances the effect of some painkillers [9].
  • Inflammation: Rats given coffee showed marked reductions in inflammatory markers (not found with decaf).
  • Microbiome: Coffee is associated with the growth of beneficial gut microbes [79]. 
  • Type 2 Diabetes: Researchers note a ”substantially lower risk” of type two diabetes with a daily coffee habit [95].
  • Heart Disease: Some studies show a lower risk of hypertension and heart disease in people who drink coffee every day [58].
  • Stroke: Some studies suggest drinking coffee could prevent strokes [50].
  • Cancer Risk: Studies show a reduced risk of colon and liver cancer in people who drink a lot of coffee [84,53].
  • Degenerative Neurological Conditions: Coffee consumption is correlated with a reduced risk of developing Parkinson's and Alzheimer's disease [41,28].
  • Overall Mortality: Frequent coffee consumption is associated with longer life [92]. 
Call out text box showing the effects of drinking.

What are 3 Positive Effects of Coffee on Our Mental Health?

Below are three positive effects of coffee on our mental health:

  • Depression: Coffee may reduce depression risk and improve mood [47].
  • Anxiety: At low doses, the caffeine in coffee may help reduce anxiety and boost mood [73].
  • Suicide Risk: Moderate coffee consumption has also been associated with lower suicide risk [52]. 

What Does Coffee Do to Your Body in the Short Term?

The short-term effects of coffee include increased awareness, concentration, energy, and focus. It may also cause a spike in heart rate and blood pressure, but this depends on the caffeine level and your tolerance.

Why is Coffee So Good for You in the Long Term?

Based on the benefits above, regular coffee consumption decreases the risk of developing chronic health diseases, including but not limited to heart disease, stroke, and cancer. People who drink coffee also live longer than non-coffee drinkers.

What Happens If I Drink Coffee Everyday?

Drinking coffee every day should be okay for most people. However, the body builds a tolerance to caffeine over time. You’d need to consume higher amounts of coffee just to feel the same effects.

Is It Okay to Drink Coffee When Sick?

Drinking coffee when you’re sick with the common cold should be okay. One study found that coffee (even decaf!) improved alertness and psychomotor performance in people with colds, bringing them to the same level as healthy people [81]. 

However, if you’re dealing with more serious health issues, especially if there’s diarrhea or vomiting involved, then it’s best to avoid coffee for a while since it can increase the risk of dehydration.

Is It Bad to Drink Coffee on an Empty Stomach?

Most people don’t have any issues drinking coffee on an empty stomach, and there’s little evidence to suggest that it can cause harm. However, coffee can increase stomach acid and may worsen the symptoms of stomach ulcers and heartburn [45].

Is Coffee Good for Your Kidneys and Liver?

Yes. Studies show coffee may be good for both the kidneys and the liver. Drinking a cup of coffee a day may lower the risk of acute kidney injury (AKI) by 15%, compared to non-coffee drinkers. The risk further decreases by 22% to 23% in those who drink two to three cups a day. Even those who have comorbidities like hypertension, obesity, and diabetes have an 11% lower risk of developing AKI than non-coffee drinkers [93].

Drinking more than two cups of coffee a day is also good for people with preexisting liver disease. According to a study, it can reduce the risk of fibrosis and cirrhosis. It also lowers cancer and mortality risk [97].

What Kind of Coffee is Good for Liver and Kidneys?

Unsweetened black coffee still remains the best coffee for the liver and the kidneys [82]. Avoid coffee with additives containing high sugar and calorie content. These include sweet syrups and creamers and milk with high phosphorus, calcium, and potassium levels. 

Does Coffee Raise Blood Pressure?

Yes, coffee causes a spike in blood pressure in the short term, but with consistent consumption, this spike becomes less significant [13].

Does Coffee Raise Cholesterol?

Yes. However, the increase in total and LDL cholesterols was seen in unfiltered coffee consumption. Consumption of filtered coffee only resulted in a minute increase in serum cholesterol [46].

Unfiltered coffee contains diterpenes like kahweol and cafestol, which can increase the cholesterol and triglyceride levels in the serum [72]. Diterpenes may also be present in filtered coffees, but the filter removes most of them.

Does Coffee Make You Gain Weight?

Unsweetened black coffee won’t make you gain weight, especially since it contains only around 2 calories and 0 fat and sugar [33]. However, the extra calories, fat, and sugar from coffee additives like sugar and cream can contribute to weight gain.

Drinking coffee before bedtime affects sleep. Sleep loss, in turn, promotes weight gain [69]. 

Is Coffee Good for Weight Loss

Coffee has been shown to support weight loss through thermogenesis [30]. Coffee is also known to suppress appetite and boost metabolism. 

Is Coffee Anti-Aging?

Studies show coffee helps slow down biological aging. According to a study, the compounds found in coffee (but not caffeine) increase telomere length. Telomeres are found at the ends of our chromosomes, and these shorten as we age. Regular coffee consumption increases telomere length by 40.3 base pairs. It also slows down cellular aging by 2.6 years [94].

What Happens When You Drink Too Much Caffeine While Pregnant?

Drinking an average of half a cup of coffee daily (around 50 mg of caffeine) while pregnant can increase the risk of delivering small-for-gestational-age babies, compared to pregnant women who abstained from caffeine. According to the study, the babies were 66 g (2.3 ounces) lighter than non-coffee drinkers [60].

Caffeine also causes vasoconstriction of the uterus and placenta, which could limit the baby’s blood supply and affect growth and development.

Early exposure to caffeine also increases the baby’s risk of developing diabetes, obesity, and heart disease later on in life.

Of note, according to the American College of Obstetrics and Gynecology (ACOG), pregnant women should limit their caffeine intake to no more than 200 mg a day [40]. 

Does Coffee Dehydrate You?

Coffee is a diuretic and makes you pee, but moderate use isn't a dehydration risk [49]. 

Does Coffee Make You Short?

No. There is no scientific evidence that shows coffee or caffeine negatively impacts or stunts one’s growth [14]. 

This misconception came from the belief that coffee causes osteoporosis. This is a bone disease wherein we lose bone mineral density and mass. Not only do the bones grow weaker and more fragile, but we also lose an inch or more of our height. However, there is no link between coffee and osteoporosis.

How Does Coffee Affect Blood Test?

The compounds found in coffee, including caffeine, can affect the results of your blood test. Coffee is a diuretic and may increase urine frequency. The dehydrating effect can mess up your lab test result [100].

Studies did show that drinking coffee an hour before a blood test statistically increased the results of the lipid and blood panels. However, the changes were not clinically significant [15,6]. 

What are the Downsides of Coffee?

Call out text box showing the disadvantages of consuming coffee.

Coffee may have a lot of benefits, but it also has some disadvantages as well. 

  • Coffee disrupts sleep and can cause insomnia, especially if you drink coffee six to eight hours before sleep.
  • Overconsumption triggers adverse side effects.
  • Coffee can be addictive and cause tolerance or dependence over time.
  • Coffee can stain teeth.
  • Low-quality coffee beans can also contain nasty compounds that are harmful to our health.
  • At a dose of 1.2 g, caffeine can be toxic; and at a dose of 10 g to 14 g, it can be fatal. 

Caffeine toxicity is more commonly caused by consuming highly caffeinated products like energy drinks and caffeine pills and rarely occurs from drinking coffee or espresso. The caffeine content of energy drinks usually ranges from 80 mg to 150 mg per 8 ounce, while caffeine pills typically have around 100 mg to 200 mg per pill [3,75]. It’s easier to overconsume these products than coffee.

For coffee to be toxic, you’d need to drink around 12 cups of coffee in a short period of time (or around 100 to 140 cups for a fatal dose!), assuming each cup has about 100 mg of caffeine.

What is the Nasty Stuff in Coffee?

Coffee may also contain nasty stuff that can harm one's health. Some of these include:

  • Acrylamide: A compound formed when coffee beans are roasted, acrylamide is toxic to the neurons. It’s also carcinogenic and may increase cancer risk [62].
  • Ochratoxin A: Found in coffee beans and other food products, ochratoxin A is a mycotoxin produced by a fungus. It is toxic to the kidneys and may also increase kidney cancer risk [12].
  • Herbicides and Pesticides: Coffee plants are often sprayed with pesticides and herbicides to control pest and weed infestation. While the processing method gets rid of these chemicals, some poorly processed beans can retain harmful levels of these residues.

This is why choosing quality beans like Cafely’s is very important. Not only does the brand use traditional growing methods but the beans are also organically grown.

Who Should Not Drink Coffee?

Call out text box showing a list of people who should avoid coffee.

Again, coffee is safe and healthy for most people. But if you have the following conditions, you may want to avoid caffeine or at least monitor your intake [18].

  • Pregnant and Breastfeeding Women: Caffeine can negatively affect the baby, so try to avoid it if you’re pregnant or breastfeeding or at least limit intake to no more than 200 mg a day.
  • Anxiety and Bipolar Disorder: Caffeine can worsen anxiety and mania symptoms, especially when consumed in high amounts.
  • Bleeding Disorder: Caffeine might interfere with clotting and worsen bleeding disorders.
  • Hypertension: Coffee might cause a spike in blood pressure in people with hypertension. However, this effect is not as noticeable in regular coffee drinkers.
  • Heart Disease: Regular coffee consumption and smoking can increase the mortality risk in people with heart disease.
  • Diabetes: Caffeine might reduce your cell’s sensitivity to glucose and cause a spike in blood sugar levels.
  • Irritable Bowel Syndrome: In high amounts, caffeine could worsen the symptoms of irritable bowel syndrome, including diarrhea.
  • Glaucoma: Caffeine might cause an increase in intraocular pressure in people with glaucoma, an effect that could last for about 1.5 hours.
  • Bladder Issues: Caffeine can negatively affect bladder control in people with bladder issues, potentially increasing urinary frequency and urgency.
  • Bone Issues: The caffeine in coffee can contribute to calcium loss and weaken bones.
