Research groups at the National Center of Neurology and Psychiatry, Nihon University, and Saitama Prefectural University have found that the resting sensation of sleep when waking up in the morning is important for maintaining the health of adults.
According to the National Center of Neurology and Psychiatry, the research group used data from follow-ups of Americans over the age of 40 over an average of 11 years to investigate the relationship between sleep time and health.
As a result, it was found that in the middle-aged generation in the prime of work, long sleep times of 414 minutes or more reduce the risk of future death, and short sleep times of less than 331 minutes increase the risk of death.In the elderly, a long floor time of 482 minutes or more, including the time of awakening on the floor, increased the risk of future death, but a significant relationship could be found between sleep time and the risk of death. I didn't.
Regarding sleep rest, short sleep times of less than 331 minutes without sleep rest increased the risk of death, while long sleep times of 414 minutes or more with sleep rest reduced the risk of death. ..In the older generation, long on-floor time of 482 minutes or more without a feeling of sleep rest increased the risk of death.
The feeling of sleep rest is presumed to reflect the physiological degree of sleep sufficiency, and is a sleep index that can be easily evaluated.The research group thinks that it may be useful for maintaining the health of adults by adopting it for health examinations and national health and nutrition surveys.
