How caffeine impacts normal body functioning?


Who doesn’t love coffee? Well, I certainly do.

Believe it or not, I am brewing a cup while writing this blog post too!

To be honest, coffee has become essential for us to function throughout the day.

But, have you ever wondered what does coffee contain that makes it such an energy booster. Yes!




It is caffeine, the most commonly used drug, that stimulates the Central Nervous System (CNS) and makes you more active. It reaches the brain and dispels dizziness and fatigue within a matter of 30-60 minutes. Foods other than coffee that contain caffeine are energy drinks, some prescribed medicines, and slimming tablets too.

More than 90% of the adult population of the US consume more than 200mg of caffeine daily. This article will look at the health benefits and also the risks caused by the overuse of caffeine.

Caffeine sufficiency

A maximum intake of 400mg per day of caffeine is found to have balanced effects. A teaspoon of caffeine is comparable to 28 cups of coffee. This means that one cup contains approximately 95mg of caffeine.

Therefore, 4-5 cups of coffee are enough for a day.

Nevertheless, a pure form of caffeine that is powdered, is highly disregarded for use. Parents should also keep it out of reach of children as it seems attractive to them.

Children and adolescents are discouraged to consume caffeine or any other stimulant before the age of twelve, at least.

Benefits of caffeine

Caffeine has many benefits, some proven some not.

Weight loss

Caffeine causes weight loss. Or more likely it prevents weight gain by

  • Reducing appetite and the desire to eat more food.

Weight loss products labeled as thermogenic are most likely to contain caffeine.

Energy booster

Of course, the best advantage of caffeine is, that it gives you energy. Making you feel less lazy and more active.

A caffeine intake of 75mg can make you more attentive and alert. It drives away sleep and fatigue.

Risks of caffeine

As benefits, there are many risks of caffeine consumption as well.

Higher caffeine consumption can cause loss of pregnancy too. Consumption of 300mg of caffeine a day is high for pregnant women. Caffeine can delay fetal growth and reduce fetal heartbeat.

Caffeine is likely to decrease the chances of the fertility of a woman by 27%.

Breastfeeding infants

Caffeine can pass, in small amounts through the breast milk, into the nursing baby. Breastfeeding mothers should not consume large amounts of caffeine as it is not good for the baby. It may cause the baby to sleep less and be uncomfortable. It can also affect a baby’s growth.

Overdose of caffeine can often trigger gout attacks in people with this disease.

Consuming a large amount of caffeine in a day can four-fold increase the risk of recurrent gout attacks.

Urinary incontinence

Caffeine drives away to ep. It keeps you awake, but it’s an ep alternative.

It can cause sleep disorders and insomnia.

Diverse effects

Consumption higher than 400mg of caffeine a day can have severe diverse effects.

Some of which are

  • High blood pressure

Bottom line

Caffeine is not as harmful as some myths foretell. However, like most drugs, overuse of caffeine can have dangerous effects on our health. It has ‘Hackney havocs’.

Nevertheless, moderate consumption of caffeine has positive effects on our body.

So it’s time to say goodbye to 20cups of coffee a day.

But worry not, you can still have 4-5 with no worries.
