Effects of caffeine

Effects of caffeine

Once consumed, caffeine is quickly absorbed from the intestines into the bloodstream.

From there, it travels to the liver and is broken down into various compounds. These substances act on different organs.

The main effect of caffeine is on the brain.

It blocks the effects of adenosine, a neurotransmitter. More adenosine helps to relax the brain and make you feel tired.

Normally, adenosine levels build up during the day, making you tired and sleepy.

Caffeine keeps you awake by connecting with adenosine receptors. This blocks the effects of adenosine, reducing fatigue.

It can also increase blood adrenaline levels and increase the chemicals dopamine and norepinephrine (euphoric hormone).

This combination further stimulates the brain and promotes a state of euphoria, alertness and focus. Because of its effect on your brain, caffeine is considered a psychostimulant.

Caffeine exerts its effects quickly.

For example, the caffeine in a cup of coffee can take as little as 20 minutes to enter the bloodstream. And It takes about 1 hour to reach full effect.

Caffeine’s main effect is on the brain. It stimulates the brain by blocking the effects of the neurotransmitter adenosine.

May protect against heart disease and diabetes.

Caffeine does not increase the risk of heart disease.

In fact, evidence shows a 16-18% lower risk of heart disease in men and women who drink 1–4 cups of coffee per day (providing about 100–400 mg of caffeine).

Other studies show that drinking 2-4 cups of coffee or green tea per day is associated with a 14–20% reduction in stroke risk.

One thing to keep in mind is that caffeine can raise blood pressure in some people. However, this effect is generally small (3–4 mmHg) and tends to fade for most people.

It may also protect against diabetes.

Those who drank the most coffee had up to a 29 percent lower risk of type 2 diabetes. Similarly, those who consumed the most caffeine had up to a 30% lower risk.

The researchers observed that the risk decreased by 12–14% for every 200 mg of caffeine consumed.

Interestingly, consuming decaffeinated coffee also reduced the risk of diabetes by 21%. This indicates that other beneficial compounds in coffee also help fight type 2 diabetes.

Caffeinated beverages such as coffee and tea may reduce the risk of heart disease and type 2 diabetes. However, this may depend on the individual.

Safety and side effects

Consuming caffeine is generally considered safe. Some side effects include restlessness, tremors, irregular heartbeat, and trouble sleeping.

Drinking too much caffeine also causes headaches, migraines and can cause high blood pressure in some people. In addition, caffeine can increase the risk of miscarriage or having a low-birth-weight baby pregnant women should limit.

Note further that caffeine can also interact with some medications. Therefore people taking the muscle relaxer Zanaflex or the antidepressant Luvox should avoid caffeine. This is because these drugs can increase their effects.

Caffeine can have side effects, including anxiety, restlessness, and trouble sleeping.

Each day our body should only consume from 200mg to less than 400mg, equivalent to 2 or 4 cups of coffee per day is the most appropriate. An overdose of coffee can also be fatal.

Therefore, for an adult, normal body, an average day should absorb about 300mg of caffeine, depending on the type, equivalent to 3 cups of coffee. Pregnant women should limit their daily intake to 200 mg.

A caffeine intake of 200 mg/time and up to 400 mg/day is considered safe. Pregnant women should limit themselves to 200 mg or less.
