Subversion! Never take a nap longer than this time! Beware of fatal diseases

Many people may have the experience that the longer they sleep, they still feel tired after waking up, showing a state of “like waking up but not waking up”, with unclear consciousness, disordered thinking and even violent tendency. This phenomenon is called “sleeping drunk” in medicine, which is very similar to the state of drunkenness. In fact, normal sleep can be divided into five different stages: sleep, shallow sleep, deep sleep, rapid eye movement, and sleep itself is a state from the shallow to the deep. In general, each sleep cycle lasts for 90-110 minutes. After falling asleep for more than 30 minutes, it will change from shallow sleep to mature sleep. Generally speaking, if the nap lasts for more than 30 minutes, the brain will go into deep sleep or deep sleep according to the instructions of the biological clock. An alarm clock or an event will wake you up. At this time, the brain is still in the stage of deep sleep, and the body is forced to “go to work”. As a result, the brain will feel very tired, unable to wake up, and have no spirit. < p > < p > in 2020, a new research result of Chinese scientists published by the European Society of Cardiology pointed out that for those who have enough sleep every night, a short lunch break of no more than one hour a day is conducive to heart health, but napping for more than one hour may increase the risk of death by 30%. < p > < p > taking a nap for more than one hour not only affects the quality and duration of sleep at night, but also increases the risk of death by 30%, and increases the risk of cardiovascular disease by 34%. < / P > < p > in addition, taking a nap for more than 1 hour at night will be far less than the normal sleep time.
