Sleeping more and less can cause premature brain failure
According to the latest report by the British “Daily Mail”, a new study published in the “Sleep” magazine in May warned that normal sleep time should be 6-8 hours per night, too much or too little sleep will lead to early brain aging 4—7 years, cognitive decline accelerated, and affects reasoning and vocabulary.
Deteriorating brain function can eventually lead to physical decline and premature death.
Scientists at the University of London conducted a five-year study of 5,431 participants in response to the question of “the effect of sleep disturbances after middle age on cognitive function in the future”.
Those who slept 7 hours a night had the best performance in the expected cognitive test, followed by those who slept 6 hours a night.
Among male participants, 6 hours of sleep, 7 hours, and 8 hours of sleep have basically the same effect on cognitive ability, but if they sleep 6 hours or more of 8 hours per night, they will potentially affect cognitive ability.influences.
Scientists say that about seven hours of sleep is extremely important for human function and health.
Insufficient sleep can affect work and life performance, slow response, and error-prone.
In addition, sleep duration is also closely related to quality of life, certain social abilities, physical and mental health, etc.
Senior judge Jane Fillet, head of the new study, said that poor cognitive ability after middle age is directly related to sleep duration.
Too much or too little sleep and poor sleep quality are causing more and more health hazards, which are getting more and more attention.
