The impact of prolonged sleep
At first glance, it may seem that prolonged sleep cannot cause harm, especially in the modern rhythm of life, when many suffer from chronic lack of sleep. However, British researchers decided to conduct their own study and analyzed data from almost 27 thousand people. All participants underwent basic medical examinations and a variety of cognitive tests.
Study Results
A study has shown that excess sleep has a negative impact on cognitive health. Participants who slept 7-8 hours a night performed better on cognitive tests. However, sleeping more than 9 hours is associated with significantly less favorable outcomes.
Side effects of long sleep
Sleeping more than 9 hours per day night may have other adverse effects such as headache and daytime sleepiness. In addition, experts note that excessive sleep combined with a lack of physical activity can increase the risk not only to health, but also to life.
Conclusion
< p>Thus, British scientists confirm that the optimal duration of sleep is 7-8 hours a day. Exceeding this time can negatively affect cognitive function and overall health.
