25 Disadvantages Of Coffee That Everyone Must Know

A drink that can make you more sociable, help you cram for your exams, or tingle your olfactory receptors, coffee is truly an emotion. However, too much of a good thing can never be good. 

Being a big fan of coffee myself, accepting the disadvantages of coffee is probably one of the hardest things I have ever had to do. But trust me, you do not want to wake up in the middle of the night from a fragmented sleep schedule.

Disadvantages Of Coffee

Let us look at the list of all the major disadvantages of coffee and learn to enjoy our beverage of choice well within limits.

1. Insomnia

The very first disadvantage of coffee is insomnia, the most common thing observed these days.

On days preceding an exam with a massive syllabus but little to no preparation time, coffee becomes our beverage of choice. 

This disadvantage of coffee is for all the students who gulp down multiple cups of it in an attempt to cram the whole syllabus in one night. 

Ever wondered what the reason behind this behavior was?

Introducing adenosine - the sleep-promoting chemical. 

The longer you stay awake, the more the amount of adenosine that builds up in your brain. Caffeine, one of the main constituents of coffee, can bind to the same receptors as adenosine. It blocks the receptors preventing adenosine from binding to them to do its job of inducing sleep.

2. Anxiety

Next on the list of disadvantages of coffee, is anxiety.

A constant feeling of worry, agitation, or feeling tense, can be classified as anxiety. However, feeling nervous about certain things is perfectly normal and you needn't be worried even one bit.

However, caffeine is believed to hold the capability of inducing anxiety attacks. Within a few minutes of consuming coffee, adrenaline gets released, which in turn stimulates our fight-or-flight response. 

Imagine being in a forest echoing with the roars of wild animals all around. You try to run but end up twisting your ankle. 

Just when that happens you hear an animal roar very close to you. Under normal circumstances, you would not even be able to move owing to the excruciating pain in your ankle. 

However, that roar induced a sense of fright within you which triggered your fight-or-flight response and gave you the energy to flee, not minding that ankle even one bit. 

Hence, next time you are gulping down an entire cup of coffee, be mindful of this disadvantage of coffee!

3. Digestive Issues

For people with pre-existing indigestion issues, this disadvantage of coffee can prove to be a nightmare. Even for those with cordial stomachs, coffee might still manage to get on the nerves causing unpleasant complications like heartburn.

Coffee is believed to relax the lower esophageal sphincter, the gate denying entry to the acid brewing in our stomach into our food pipe. This might lead to acid reflux, hence causing complications.

The issue might be aggravated on varying levels depending on the roast type of the coffee beans. Some roasts are believed to be more acidic than others hence inducing more prominent effects. 

4. Bad For Pregnancy

Another disadvantage of coffee is that it is not healthy for a pregnant woman.

Many of you might already be familiar with this disadvantage of coffee. Nurturing an entire human being for 9 months inside one’s own body is no joke. 

Although a beautiful journey, there exist hundreds of things that a mother needs to be mindful of, coffee being one of them.

When taken in moderate amounts, pregnant women can enjoy their cup of coffee without any lingering feelings of worry. 

When the consumption pattern crosses the limits, there might occur increased blood pressure and heart rate, neither of which are advised during the pregnancy. 

Coffee also increases urination frequencies possibly leading to dehydration.

Most importantly, increased chances of miscarriage have been linked to over-consumption of coffee. 

5. LDL Cholesterol Levels Increase

In the past few years, cholesterol has sadly become the victim of marketing strategies used by nearly every cooking oil brand in India. 

Promoting themselves as the protagonist ready to save us all from the villain cholesterol, these brands have created a misleading fear of the substance amongst the crowd.

Apologies for breaking your bubble, but without cholesterol, none of us would be alive. There exist two types of cholesterols – HDLs and LDLs. Consider the former your best friend and be mindful of only the latter. 

Coffee is speculated to play a role in increasing LDL levels in the body. Therefore, the risk of developing thick arterial walls (the vessels that circulate blood throughout our body) leading to possible blockage and heart complications increases. 

We all know that heart complications are no joke. So, be careful about this disadvantage of coffee!

6. Addictive

I can personally vouch for this disadvantage of coffee. Like mentioned earlier, caffeine can bind to adenosine receptors in the brain hence preventing the body from feeling tired. 

I mean, who would not enjoy this sudden burst of energy that can be utilized in all sorts of activities from socializing to cramming? I certainly did!

This burst of energy leaves one aching for more, also rendering an individual incapable of handling the sudden dip in energy leaving you groggy and extremely tired. 

Hence, people can be seen using that cup of coffee as a mandate for delivering good performance out in the crowd of busy and constantly moving people.

7. Restlessness

This disadvantage of coffee can again be attributed to the adrenalin release triggered by caffeine. 

As mentioned earlier, too much of a good thing can never be good. Too much adrenaline in our system makes it difficult for our body to handle it, giving us jitters and restlessness. 

8. Blood Pressure

The next disadvantage of coffee is blood pressure.

Speculations surrounding this disadvantage of coffee are believed to have more than one plausible reason. 

The first one being coffee’s ability to cause blockage of hormones responsible for keeping arteries wide and open for blood to pass through seamlessly. That might increase the pressure exerted by blood on the walls of the vessels hence elevating blood pressure.

Another possibility is the increased release of adrenaline from the adrenal glands that causes constriction of blood vessels in the body. 

9. Increased Risks of Heart Attacks

One needn't be a doctor to grasp how frightening a heart attack is. 

What happens in a heart attack? 

Our heart is a pumping machine that constantly pumps blood to the different parts of the body. Ever imagined what will happen if it suddenly stops working? 

Whatever imagination this question might induce is what a heart attack is. 

When coronary arteries constrict due to the accumulation of substances like cholesterol (remember – not all types of cholesterol!), the blood supply to the heart decreases and might even stop entirely. 

That prevents tissues from remaining parts of the body from getting blood, hence oxygen, causing them to die. 

As coffee is believed to play a role in increasing LDL levels in the body, it is suspected to play a role in causing heart attacks. So, watch out for this disadvantage of coffee!

10. Breast Tissue Cysts

Although not a direct reason behind the development of cysts in breasts, caffeine-induced hormonal imbalance is believed to be one of the contenders in the list of reasons behind the development of the said cysts.

If not cysts, caffeine can also cause breast pain. So, put that second cup of coffee at 10 in the morning down!

11. Urinary Incontinence

Hearing this term for the first time? No problem! Urinary incontinence refers to the increased urge to urinate.

What does coffee have to do with it you ask? 

The culprit here is caffeine again. Caffeine increases blood flow to the kidneys raising the amount of blood getting filtered and urine production. This increased urine production causes the urge to keep using the bathroom more often than usual.

12. Type 2 Diabetes

This disadvantage of coffee is specifically for people living with Type 2 diabetes.

Type 2 diabetes, also called diabetes mellitus, is the body’s refusal to produce enough insulin to process blood sugar well. 

Caffeine is believed to make the cells of our body even more insensitive to insulin. 

The blood sugar levels post-meal increase even more than usual as the insulin being produced by the body is not able to enter the cells and process blood sugar.

13. Overdose

 The sense of social, mental, and physical well-being brought about by coffee immediately post its consumption makes it very easy for consumers to keep wanting more. 

 Consequently, it is very easy to overdose on caffeine. 

Symptoms like increased restlessness, anxiety, and even disturbed circadian rhythms (our biological clock) are most common.

14. Collagen Production

Are you one of those with a day and night skincare routine? This disadvantage of coffee might be for you!

It has been believed that caffeine interferes with collagen production when taken in large amounts. Collagen maintains the elasticity of our skin. In its absence, your skin will start to sag.

In simple terms, you are causing your skin to age faster by gulping multiple cups of coffee in a day.

15. Increased Intraocular Pressure

Intraocular pressure refers to the pressure exerted on the optic nerve by the fluids in the eye. Excessive fluid accumulation in the eye causes the pressure being exerted on the optic nerve to increase. It leads to a condition called glaucoma.

It is under speculation that excessive amounts of caffeine intake can increase intraocular pressure. 

Therefore, this disadvantage of coffee can prove to be detrimental to eyesight.

16. Interferes with Ossification

Ossification is the formation of new bone tissue. Have you ever imagined yourself without bones?

Caffeine is believed to increase calcium excretion from the body. Calcium is the main component of bones. That is why its deficiency can prove to be quite detrimental to the formation of new bones.

If you wish not to end up like a shapeless puddle, be mindful of this disadvantage of coffee!

17. Worsens Menopause Symptoms

Menopause marks the end of a woman’s menstrual cycles, mainly observed in women in their 40s or 50s. 

On the side, it marks the increase of blood loss cycles every month, along with painful period cramps and many other unpleasant symptoms. But on the other side, it comes with its own set of complications. 

Night sweats and hot flashes are the most common type of unpleasant occurrences following menopause. Caffeine is believed to aggravate these conditions hence making menopause even harder to bear.

18. Caffeine Allergies

Pretty sure everyone is familiar with some form of allergy or the other. Sneezing, rashes and itching are some of the most common allergic reactions. However, there exist some significant sets of allergic reactions as well. 

Although not very well known, caffeine allergies do occur in some individuals that are unfortunately often mistaken to have been caused by some other substance. 

These allergies can cause some significant reactions in the body, including anaphylactic symptoms, which indicate swollen tongue or throat leading to difficulty in breathing. 

Therefore, this disadvantage of coffee is certainly not to be taken lightly.

19. Reduces Fertility

This disadvantage of coffee is more for men than women. Excessive caffeine can cause more prominent fertility issues in men than in women.

Caffeine lowers sperm count decreasing the chances of fertilization.

Therefore, keep an eye on how many cups of coffee you are gulping in a day! 

20. Headaches

This disadvantage of coffee might come as a shock to most of you. More often than not, drinking a cup of coffee is often viewed as a remedy to headaches, and rightfully so. But ironically, most of the time, the reason behind that headache is coffee itself.

As mentioned earlier, caffeine can cause constriction of blood vessels hence reducing blood flow to the brain. When you suddenly go cold turkey on coffee, the blood vessels widen allowing more blood around the brain. 

This puts pressure on the blood vessels, ultimately leading to throbbing headaches.

21. Gout Flare-ups

Gout refers to the accumulation of urate crystals in our body’s joints causing inflammation and pain. It is also called inflammatory arthritis.

There exist multiple speculations around the relation between caffeine and gout. Some researchers believe caffeine to have a chemical structure similar to that of the medication used for treating gout hence helping with gout flare-ups.

However, others have pointed out that the medication used for treating gout is only effective when used long-term. 

Painful symptoms during the initial few days of use are common. Similarly, short-term coffee intakes might worsen gout flare-ups.

Although still speculation, better safe than sorry, right? 

22. Slows Down Recovery from Hearing Loss

Caffeine, although not directly related to hearing loss, might slow down recovery from noise-induced hearing losses. 

You might think that you are not directly at risk since you have never been exposed to noises loud enough to impair your hearing. But trust me, it is more common than you think.

Remember that ringing sound that keeps playing inside your ears once you finally come out of that pub or house party, or a loud political rally even? That is what noise-induced hearing loss is. 

Under normal circumstances, our body recovers from such issues in a matter of 72 hours at max. 

However, it is believed that coffee causes this recovery to slow down hence putting us at risk of permanent hearing loss.

So next time you are considering sipping coffee to remedy your hangover headache following a night of loud music and partying, be mindful of this disadvantage of coffee!

23. False Sense of Focus

You will probably have a hard time believing this disadvantage of coffee. 

What if I told you that the sense of focus brought about by coffee is false? No amount of coffee can undo the tiredness that your body feels from doing chores the whole day. 

It might take up the place of adenosine, but all the adenosine does not just vanish. It is still there. The moment the effect of caffeine wears off, people crash into their beds falling asleep for hours in a row. 

24. Hallucinations

Although hard to believe, this disadvantage of coffee is pretty scary at the same time.

Caffeine interrupts your sleep cycle. After all, it is the sole reason why you consumed it (apart from the fact that it tastes and smells heavenly). That can make you see things that are not even there during those few seconds of a broken sleep spell. Pretty scary right?

The reason behind this is believed to be the release of the stress hormone cortisol. When people under stress consume caffeine, cortisol levels are believed to increase even more than usual. That can cause mild hallucinations. 

Instances where I have imagined someone pulling the blanket off of me, falling from my bed repeatedly, have occurred. Don't know about you, but that is not the kind of adrenaline rush I enjoy.

25. Increased Consumption of Sugary Beverages

Once again, the main culprit here is caffeine. This constituent of coffee is often added to other sugary beverages like Coke and other soft drinks to enhance their flavors.

Since the excessive intake of coffee builds an addiction in the individual, specifically towards caffeine, consumers go looking for a similar type of taste and feeling in other drinks. Finding them in those sugary drinks tends to increase their consumption frequency leading to severe issues like obesity and diabetes. 

Although loved by many, especially including me, coffee comes with its own set of disadvantages. It is true about most things in life. Whatever the substance in focus might be, it is always good to keep it well within limits.

Being someone whose first cup of coffee in the morning keeps her going through all the socializing and lectures, followed by multiple refills throughout the day, these disadvantages of coffee have been the trickiest mountain to climb.

These disadvantages of coffee are certainly not an indication to throw that fresh packet of coffee in the trash. 

These are simply a reminder to keep your intake in check and keep enjoying this lovely beverage!
