What is Caffeine?
Definition of Caffeine
Caffeine is a natural stimulant that belongs to a class of compounds known as xanthines. It is found in various plants, including coffee beans, tea leaves, and cocoa beans. Caffeine is a psychoactive substance that can stimulate the central nervous system, resulting in increased alertness and energy. It is also known to improve mood, concentration, and cognitive performance.
How it Affects the Body
When caffeine is consumed, it is rapidly absorbed into the bloodstream and transported to the brain, where it blocks the action of adenosine, a neurotransmitter that promotes sleep and suppresses arousal. As a result, caffeine can increase the levels of other neurotransmitters, such as dopamine and norepinephrine, which can enhance mental and physical performance.
However, the effects of caffeine can vary between individuals, depending on factors such as age, weight, and genetics. Some people are more sensitive to caffeine than others and may experience side effects such as jitters, anxiety, and insomnia.
Recommended Daily Caffeine Intake
The recommended daily caffeine intake varies depending on age, weight, and health status. According to the Dietary Guidelines for Americans, moderate caffeine consumption is defined as 400 mg per day, which is equivalent to about 4 cups of coffee or 10 cups of green tea. However, it is important to note that caffeine sensitivity can vary between individuals, and some may need to consume less caffeine to avoid side effects.

Side Effects of Caffeine
Caffeine is a natural stimulant that provides many benefits, but it can also have negative effects on the body if consumed in excess. Here are some side effects of consuming too much caffeine:
Insomnia and Restlessness
Caffeine can make it difficult to fall asleep and stay asleep, leading to insomnia and restlessness. This can have a negative impact on your overall health and well-being, as sleep is essential for proper functioning.

Consuming too much caffeine can lead to jitters and anxiety, making you feel on edge and restless. This can make it difficult to focus and complete tasks, leading to decreased productivity and performance.

Switch to Decaf or Herbal Tea
Decaf or herbal tea is a great alternative to caffeinated beverages such as green tea. It provides the same benefits without the negative side effects of caffeine.
Limit Consumption of Caffeinated Beverages
Limit your consumption of caffeinated beverages to reduce your overall caffeine intake. This can be done by switching to decaf or herbal tea, or by reducing the number of cups of green tea you drink per day.
Stay Hydrated
Drinking plenty of water can help to flush caffeine out of your system and reduce its negative effects. Aim to drink at least eight glasses of water per day.
