Scientists talked about the effect of coffee on the cycle of sleep and alertness of a person

0 < p>Scientists representing the University of Edinburgh studied the effects of coffee and concluded that drinking the drink in the morning helps to concentrate. According to experts, this is especially relevant if sleep disturbances are observed.

Researchers found that the less coffee a person drinks 6 hours before bedtime, the lower the effect on its quality. With irregular sleep, the drink helps to reduce short-term cognitive impairments caused by lack of sleep.

If you consume 300 mg of caffeine per day, alertness, reaction, accuracy and working memory improve in the first three days of poor sleep.< /p>

People using the drink while working the night shift noticed an increase in psychomotor characteristics and alertness. But it can affect the quality and duration of sleep in the future. Experts came to the conclusion that the quality of sleep depends on the amount of caffeine, its use during the day and individual susceptibility.

“About 80% of the world's population drinks coffee every day. Most often, this happens due to a feeling of cheerfulness and concentration of attention. Its effectiveness can last for several hours, depending on metabolism. When a sleep disorder is detected, preference should be given to drinks with a low caffeine content,” said the author of the report, Professor Renata Rikha, who is the author of the study.
