Caffeine is a psychostimulant found in tea, coffee, and many other beverages. What else is known about this substance?
Instructions
Step 1
Caffeine has a positive effect on short-term and long-term memory. Taking at least 300 mg of this substance per day will protect you from Alzheimer's disease and cognitive impairment. But keep in mind that good sleep is also needed to prevent Alzheimer's disease.
Step 2
Athletes who take caffeine an hour before training improve their response and alertness. Also, this psychostimulant helps to reduce the feeling of fatigue and improves performance.
Step 3
Caffeine can have a positive effect on the reaction rate. This substance crosses the blood-brain barrier extremely quickly, which is why the central nervous system is stimulated just as quickly. All energy drinks are based on this principle, but they should be taken in moderation, because caffeine increases the excitability of the nervous system.
Step 4
It is believed that caffeine can prevent depression. And it is true. Many studies have shown that those who drink more than a couple of cups of coffee a day suffer from bad mood and depression less often than those who do not drink this drink at all.
Step 5
Does caffeine raise blood pressure? And this is true. It's not for nothing that people with high blood pressure rarely drink coffee, because caffeine can actually raise blood pressure. But this increase turns out to be low and short-lived in healthy people and a little faster and longer in people predisposed to hypertension. But those who consume caffeine have an immoderate long-term effect of increased blood pressure. The norm is a couple of cups a day.
