Professor Zhao Yufeng, a monitoring expert from China National Environmental Monitoring Center, told the reporter that general household appliances will produce electromagnetic radiation, but electromagnetic radiation and electromagnetic pollution are two concepts. Household appliances generally use low-voltage electricity and only produce low-frequency electromagnetic radiation; However, electromagnetic pollution will have negative effects on human body only after the electromagnetic radiation exceeds a certain intensity (that is, the limit of safety and hygiene standards), such as headache, insomnia, memory loss, blood pressure rising or falling, and critical abnormality of heart. According to the relevant national standards, as long as it is less than12v/m, the electromagnetic radiation of household appliances will reach the standard.
Professor Zhao said that ordinary household appliances, such as televisions, refrigerators, washing machines and so on. There is almost no electromagnetic radiation. As long as it is not placed in the center and is away from the place where people often go 1.5 meters, the harm to human body can be greatly reduced. Relatively speaking, the radiation of microwave oven is relatively large, so use it as little as possible. In the radiation ranking of indoor appliances published by China National Environmental Monitoring Center, microwave oven ranks first, and its radiation amount is nearly double the national standard, making it the most dangerous "health killer" at home.
Professor Zhao also reminded that the magnetic field of low-voltage power supply with transformer is relatively high, but the distance of 0.3 meters can ensure safety. For example, mobile phone chargers should be kept at a distance from people when charging, especially not on the bedside.
Pay attention to the ventilation of household appliances. In a closed environment, electromagnetism can separate the ionosphere in the air, and the ionosphere is easily adsorbed on human skin, which is harmful to health.
Radiation from adjacent rooms can't be ignored. Most of the pipes of household appliances are connected at the rear, where the magnetic field is the highest and the penetration of the magnetic field is relatively strong, so we should also pay attention to the position separated from it by a wall.
Try to shorten the time of contact with household appliances; Be sure to wash your face before going to bed; It's better to turn off the power of unused appliances, because charged appliances will also produce radiation.
Children, pregnant women and the infirm should strictly control the time and distance of watching TV and playing computer.
In diet, we should consciously eat more foods rich in vitamin A, vitamin C and protein, especially kelp, which can effectively strengthen the ability to resist electromagnetic radiation.
Insomnia is a physiological disorder with unsatisfactory quality and/or quantity of continuous sleep. Anxiety or fear of insomnia is the pathogenic psychological factor of this disease.
Insomnia is a common sleep disorder. It can be secondary to physical factors, environmental factors, neuropsychiatric diseases, etc. This disease is the so-called primary insomnia caused by mental stress, anxiety and fear, and fear of insomnia. Its symptoms are difficulty in falling asleep, not deep sleep, easy to wake up, early to wake up, dreaminess, fatigue or unconsciousness after waking up. Sleeping during the day seriously affects work efficiency or social function.
Usually the onset time of insomnia is at least three times a week and lasts for more than one month.
In order to distinguish different stages of insomnia, insomnia can be divided into three forms: difficulty in falling asleep, unstable sleep state and early awakening.
First, keep a good attitude of optimism and contentment. Have a full understanding of social competition and personal gains and losses. To avoid psychological imbalance caused by setbacks.
Second, establish a regular daily life system and maintain a normal sleep-wake rhythm.
Third, create a conditioned reflex mechanism conducive to falling asleep. Such as taking a hot bath, soaking feet and drinking a glass of milk half an hour before going to bed. As long as you persist for a long time, you will establish a "sleep conditioned reflex."
Fourth, moderate physical exercise during the day will help you fall asleep at night.
Fifth, develop good sleep hygiene habits, such as keeping the bedroom clean and quiet, away from noise and light stimulation; Avoid drinking tea and alcohol before going to bed.
Six, self-regulation, self-suggestion. You can play some relaxing activities, or count them repeatedly. Sometimes a little relaxation can accelerate your sleep.
Seven, limit the sleep time during the day, in addition to the elderly can take a nap or nap during the day, should avoid taking a nap or nap, otherwise it will reduce the sleepiness and sleep time at night.
In addition, for some critically ill patients, under the guidance of a doctor, sleeping pills or small doses of anti-anxiety and antidepressants should be given in a short time. This may lead to faster and better treatment results.
