Pros and Cons of Caffeine Intake

Caffeine is the most widely psychoactive consumed drug. This stimulant is unregulated and legal in most parts of the world. Some famous caffeinated drinks include Tea, Soda, energy-based drinks that of course include coffee as well. Caffeine is a naturally occurring chemical stimulant called trimethylxanthine.  Did you know that more than 450 million cups of coffee are consumed each year in the United States alone? That sums up to about 90% of the country’s population.

Caffeine brings about that extra kick of energy that we all need to get going throughout the day; this may not come as a surprise, considering the vast use of caffeine worldwide.

Most teens, adults and even elderly consider their daily dose of caffeine intake as a serious necessity rather than a luxury. People addicted to caffeine, especially black tea, stored it by buying wholesale tea prices as it is believed that the stimulant promotes significant blood flow which triggers an individual to be relatively hyperactive. Caffeine can even be found in places you’d lead expect them to be; caffeine-infused bottled water, for instance, or even dark chocolate! Despite all the obvious reasons, caffeine consumption has several risks and health benefits attached. Check out these amusing pros and cons of caffeine intake.


Prevention against health-related issues:

It’s almost amusing to know the potential caffeine possesses to prevent health-related diseases. Some of which are listed below:

  • Oral Cancer- As per a study, drinking 4 cups of coffee daily could decrease the risk of dying from oral cancer by 49%, compared to those individuals who drank little to no coffee at all. Similar circumstances apply for skin cancer, neck cancer, prostate cancer, and even breast cancer.
  • Alzheimer’s disease– based on the several proven facts related to improved brain stimulation, it may not come as a surprise that lifelong caffeine consumption decreases the risk of falling prey to Alzheimer’s and even Parkinson’s disease.
  • Cataracts– Caffeine protects the lens of the eye against damage that could potentially form cataracts which in turn lead to a blurry and vision.
  • Type 2 diabetes– As ironic as it might sound, studies have found how consuming a little more than your daily caffeine intake may prevent the risk of you getting type 2 diabetes by 1%, compared to those with a lower caffeine consumption that increases the risk of diabetes by 17%.
  • Weight loss– Consuming caffeine can develop a loss of appetite and can prevent obesity and at most even encourage weight loss.
  • Kidney Stones- Increased caffeine intake in the long-run can decrease the risk of you suffering from kidney stones.
  • Strokes– Drinking more than one cup of coffee a day can potentially decrease the risk of you suffering from a fatal stroke by 22% to 25% (if you have no history with cardiovascular diseases) compared to those who don’t consume coffee at all.
  • Prevents suicide – Thought it might sound a bit absurd, a study at Harvard University claims how drinking several cups of coffee a day could lower the risk of suicide in men and women by 50%.

Promotes the central nervous system (CNS):

Trimethylxanthine is a proven psychoactive chemical that promotes mild central nervous system (CNS) stimulation when consumed. It improves concentration and focus. Consuming up to 75gms of caffeine can increase alertness and attention. An increase in the daily dose can even promote speed reasoning and memory. Caffeine affects adenosine receptors in the brain. Studies indicate that drinking coffee may enhance thinking skills and slow down the process of mental decline that comes with age. Another research claims how consuming caffeine after a learning session could boost long-term memory.

Improves physical performance: 

Caffeine also helps with psychical activity. Endurance performance and capacity could be further improved based on your caffeine intake. No wonder most pre-workout supplements contain caffeine that entices athletes with extraordinary claims of increased stamina and gains. As per a recent study, it was proven how athletes who consumed carbs and caffeine post-workout possessed 66% more glycogen levels than athletes who just ingested carbs alone. Glycogen is a fuel muscle use to function. So whether you’re lifting weights, running ten miles or are even aiming for a tough workout, know that an increase of glycogen levels will aid athletes to recover faster and perform the better next time.


Despite all the benefits of caffeine intake and the research and studies attached to it, this all occurs undoubtedly with some risks involved. As stated below:


It’s no myth how caffeine consumption could lead to sleep deprivation. While it may be beneficial in the morning, it could seriously bring adverse effects to your sleep schedule, especially if consumed 3 to 6 hours before your bedtime.


Dietary and medicinal products infused with caffeine could lead to migraines and could trigger chronic daily headaches or ‘rebound’ headaches. Causing more harm than good when it comes to you being productive throughout the day, this defies the purpose of caffeine.


High levels of caffeine intake could worsen one’s mental health, especially if they’re already suffering from depression. While it may not be directly related, this could come about as caffeine consumption can cause higher weight gain, a poor academic performance that could ultimately lead to depression amongst youngsters.

Caffeine withdrawal:

Caffeine withdrawal is similar to when addiction is put to a halt. Individuals who religiously consumed high levels of caffeine and then suddenly discontinued its consumption could cause some temporary side effects. Anxiety, fatigue, low energy levels, lack of concentration, mood swings, irritation, and depression, are all infamous symptoms for those who suffer from caffeine withdrawal. These factors with negative impacts could last from anywhere between two to nine days.


Every factor or element in life comes at a risk of something else. While some studies indicate how caffeine could prove to be beneficial in many ways, others encourage refraining from the consumption of caffeine and often even contradict with its stated ‘benefits.’ Every individual is different, and depending on your source of caffeine intake, it may be best to consult a doctor before making any choices, for precautionary purposes.
