What is Caffeine and What Does it do to Your Body?

Have you ever stopped to consider just what caffeine is? What exactly does it do to your body and why? Understanding this chemical that is so easily found in many things we consume in today’s society is important. In order to know if this chemical is harmful to your body, you must first know what it does.

Caffeine is a tasteless compound that is a derivative of different plant sources. It acts as a stimulant to the central nervous system which means that it increases the activity in your brain and nerves. This is why one of the first things you recognize in your body after consuming caffeine is alertness.

You can feel these effects as early as 15 minutes after consumption and they can last for up to 6 hours. Caffeine can be found in more than coffee. It is also found in teas, sodas, energy drinks and – surprise! – chocolate.

Positive Effects of Caffeine

Although many say that caffeine is not good for you, there are actually quite a few benefits from consuming caffeine in moderation. Caffeine can help brain function. The Harvard School of Public Health discovered that by drinking two to four cups of coffee a day can reduce the risk of suicide in adults.

Another study showed that 200 mg of caffeine a day (in any form) can enhance your memory. Who knew that that cup of steamy goodness or that piece of dark chocolate could have such a great effect on the brain? Caffeine can also help speed up metabolism and weight loss.

Caffeine increases metabolism by 11% because of its ability to stimulate the central nervous system. It has also been proven that by consuming 300 mg of caffeine a day, you can burn an extra 79 calories. Caffeine enhances exercise performance.

Enhanced Focus

Regular caffeine intake has been linked to improving focus, attention, and concentration. This could be due to caffeine’s ability to block adenosine, which is a sleep-inducing molecule, from connecting to its receptor in the brain.

Enhanced Motivation

The stimulant effects of caffeine have been linked to increased motivation and drive. Studies have shown that caffeine can increase feelings of happiness and reduce feelings of fatigue. This can result in improved dedication and productivity.

Negative Effects of Caffeine

Just like with many other things, caffeine must be consumed in moderation. Although there are so many positive benefits of caffeine, there are still some negative effects that you should look out for. Because caffeine is a stimulant it is imperative to consider consumption times. Ingestion of caffeine close to sleeping hours can result in disrupted sleep or even insomnia.

Medical News Today shared that if caffeine is consumed 6 hours before bed, it lessens sleep by at least one hour. It is also important to be mindful of how much caffeine you are consuming on any given day. The average amount of caffeine that should be consumed in a day is up to 400 mg. If more than this is consumed, you are exposed to risks such as headaches, restlessness, dehydration, anxiety, rapid heart rhythm, even possible convulsions.

Yes, caffeine is a wonderful gift from mother nature, but without a full understanding on the impact of this chemical on your body, there is potential for harm to your body. It is best to stay informed so that you are able to enjoy the benefits and have caffeine positively impact your life.

Caffeine Side Effects

One of the drawbacks of caffeine consumption is the potential for sleep disruption. While caffeine can give you a boost of energy, too much caffeine can impact your sleep and make it harder to drift off. To minimize the risk of sleep disruption, it is important to avoid consuming caffeine after 12 pm and to keep your caffeine intake in the morning to light to moderate amounts.


Another common side effect of caffeine consumption is dehydration. Since caffeine is a natural diuretic, it can increase the frequency of urination. However, if caffeine is consumed in moderation and balanced with adequate hydration, there should be no cause for concern regarding excessive dehydration.
