Tea lover

Many people drink tea or coffee in the morning and don't feel fully awake without it. But have you ever wondered how much caffeine these drinks contain and how much caffeine you need throughout the day? Before answering these questions it is important to know about caffeine.

What is caffeine?

Caffeine is a central nervous system stimulant belonging to the methylxanthine class, associated with alertness, healthy metabolism, and improved mood. It is commonly found in coffee, tea, caffeinated pre-workout supplements, and other beverages. Caffeine works by blocking the adenosine A receptor from binding to adenosine, which promotes the release of the neurotransmitter acetylcholine.

How much caffeine do you require a day?

According to the FDA, the recommended daily dose of caffeine for a healthy adult is 400 mg, however, this amount is different for people who have some sensitivity to caffeine.

Although the FDA has not set a caffeine limit for children, the American Academy of Pediatrics recommends that children not consume caffeine or other stimulants. If a person is sensitive to caffeine, they can also use a lower dose of caffeine instead of 400 mg, as this sensitivity varies among people. For this, it is necessary to contact the physician.

Benefits of caffeine:

Caffeine, when used in recommended quantities, can help increase your concentration, improve cognitive performance and athletic performance, and aid in weight loss.

While some studies have linked caffeine consumption to an increased risk of Alzheimer's disease, skin cancer, kidney stones, stroke, and type 2 diabetes, more research is needed.

Side effects:

Caffeine can cause some short-term to long-term side effects, especially when consumed more than the recommended amount. Its most common side effect is sleeplessness, however, palpitations, high blood pressure, restlessness, headache, and frequent urination can also occur.

According to experts, it is safe for most people to consume 3 to 5 cups of coffee per day, with no more than 400 milligrams of caffeine per cup. Exceeding this limit can be considered a caffeine addiction.
