Due to the impact of the new corona epidemic, many people’s life, work and even sleeping habits have undergone great changes. The survey shows that although people spend more time at home, the total time to fall asleep has been delayed by 2-3 hours and searches for sleep problems have also increased by 43%. Many sleep problems, such as snoring, sleepwalking, and insomnia, are plagued by contemporary adults.
What is considered deep and restful sleep? Does dreaming and snoring mean deep sleep? Can sports bracelets reflect our true sleep conditions … March 21 is World Sleep Day. Professor Han Fang, Secretary General of the World Sleep Society and Director of the Peking University People’s Hospital Sleep Center, gave a detailed description of these misunderstandings about Sleep Interpretation, let’s see if you’ve been hired.
People who love to dream don’t actually sleep well.
Sleeping “I love to dream” is not necessarily a good thing. Professor Han Fang said that each of us is dreaming every night. Some people completely forget the content of dreams after waking up, but some people can remember special things. don’t sleep well.
In clinical practice, elderly men often experience uncomfortable sleep at night, and some people even beat their spouses until they sleep with bruises and puffy faces. Professor Han Fang recalled, “This kind of dream is a violent dream.” Serious diseases, especially senile neurodegenerative diseases, such as Parkinson’s disease or Alzheimer’s disease.
There is also a type of patients who, regardless of day and night, regardless of the environment, suddenly “fall asleep in a second”, this is called narcolepsy. Professor Han Fang recalled that attention should be paid to this type of disease, because patients often suffer a sudden loss of strength and fall asleep when surprised, laughing, frolicking or angry, etc., which is commonly known as cataplexy. There can be accidents at any time.
Prolonged snoring increases the risk of death
Many people think that snoring is a sign of deep sleep. But this is not the case. People who snore often suffer from a condition called sleep apnea syndrome. This disease not only affects the quality of sleep, but it even carries the risk of sudden death. Many apnea patients have sudden nocturnal deaths after drinking, and most of them are attributed to sudden cardiac death, but in fact, the nocturnal killer of “apnea” cannot get rid of it.
In addition, prolonged apnea can also be accompanied by obesity, diabetes and high blood pressure, these diseases will undoubtedly increase the risk of death. Professor Han Fang especially emphasized that sleep apnea is a night killer. He especially likes dangerous young adults who are rich and understanding. If snoring stops suddenly during sleep and resumes after turning over, please be alert.
The sleep data from the smart bracelet cannot be used as a diagnostic basis.
In recent years, more and more people like to wear smart bracelets and monitor exercise and sleep quality through “health” functions such as step counting, heart rate measurement, and sleep measurement. But Professor Han Fang noted, “First of all, whether for medical or health reasons, it has many limitations.”
In the actual medical process, the data detected by the smart bracelet often cannot be used as a reference for the doctor’s diagnosis. If a patient comes to see a doctor, the hospital will use standard diagnostic equipment. After the patient enters a sleeping state, he will monitor the heartbeat, brain waves, respiration and many other data, comprehensively judge and determine if there is a sleep problem. .
Therefore, the health care smart bracelet data can only be used for daily reference, but the accuracy is far from reaching the professional level.
Playing mobile phones before bed does not promote sleep
It can be said that mobile phones are the “soft killers” of sleep. Many people are in the habit of playing with mobile phones before bed and feel that they can help them sleep. In fact, playing with mobile phones has a great impact on sleep. Whether it’s hotspots for the news, celebrity gossip, or the “Versailles” circle of friends where travel and delicacy are exposed, they will stimulate the brain and reduce drowsiness. In addition, the “bright light” emitted by the mobile phone screen can also stimulate the optic nerve, causing a delay in the secretion of melatonin, exciting the brain and dissipating drowsiness, thus delaying the time to fall asleep. There are even studies that have found that if the phone is placed next to the pillow, even if it is not used, people will lose more than 20 minutes of sleep on average.
