For many people, a nice cup of coffee in the morning is the best start of their daily routine. We've all heard the benefits of drinking coffee, or better yet, caffeine. Although, there is more to caffeine that we often overlook. For instance, caffeine is a classified drug that can lead to addiction.

WHAT IS CAFFEINE

Caffeine is a chemical substance naturally produced in the leaves and seeds in many plants. A NPR article stated, due to the nature of caffeine as a stimulant to the central nervous system, scientists have classified caffeine as drug. 

Since the discovery of caffeine and its effect, caffeine has been added to many food and drinks in our daily life including coffee, tea, energy drinks, chocolate, candies, and some chewing gums. A large market in caffeine has made FDA conduct further investigation, hoping to raise awareness toward caffeine consumption. During an announcement by FDA, it was said that adults safety level of caffeine consumption be about 400 milligrams each day.

CAFFEINE PSYCHOLOGICAL EFFECT

According to Dr. Hartney, PhD, there are several positive effects that caffeine has on human mind, including:

  1. Increases alertness

  2. Boosts our mood

  3. Improves performance (response times, information processing, and more)

At the same time there are side effects of caffeine consumption:

  1. Increases anxiety

  2. Insomnia

  3. Dizziness

  4. Restlessness

Overall, caffeine is not the best way to improve mental performance. As it was mentioned earlier caffeine functions as a drug to the human body. Excessive caffeine consumption will build up tolerance and dependency. Eventually, people will experience withdrawal even with proper amount of rest. Ultimately, the best way to increase our mental performance is a healthy diet, actively excising, and quality sleep.
