Ringtones will also increase your overall stress level. Sudden noise will cause the body's protective conditioned reflex "fight or flight" and increase the level of adrenaline. Dr. Mark Atkinson, who specializes in how to deal with this disease, believes that although the bedside clock may help you go to work on time, if this activation lasts for a few days, weeks or months, it will lead to chronic stress. Stress can lead to high blood pressure, sleep problems and depression. If you are suddenly awakened in a "deep sleep", your thinking ability will undoubtedly be seriously affected, so that it is like being drunk.
Our sleep is divided into stages and cycles-each cycle lasts about 90 minutes. Every cycle we go through five different stages of sleep, including shallow sleep, deep sleep (during which the body recovers itself and it is difficult to wake up) and rapid eye movement sleep (often accompanied by dreams). Scientists have found that when a sleeping person is awakened, it will affect his short-term memory ability, cognitive ability and even calculation ability. The findings were published in the Journal of the American Medical Association earlier this year.
Participants' best performance in the experiment awakened by the alarm clock is only 65% of the normal state, which is equivalent to being drunk-participants' performance is worse than that of being deprived of 26 hours of sleep. Although the serious impact will gradually decrease in the first ten minutes after waking up, some damage can still be found within two hours after waking up. The researchers said that this result will affect those workers who need to perform their duties at their best immediately after being awakened, such as firefighters, doctors and other emergency workers.
The technician explained that the electronic watch would emit electromagnetic fields. Although the electronic watch is much better than before, it still produces electromagnetic fields. There is still a constant debate about the harm of electronic watch radiation to health, but some people think that it will lead to cancer, especially for children, and it will also bring a series of other nervous system problems. Experts suggest that the alarm clock should be at least 1 m away from your head when you sleep.
Therefore, it is not good to put the alarm clock, watch, mobile phone and other items on the bedside when you sleep at night, and it should be harmful to your health! !
