The winter cold, we all like to enjoy Waterloo home heating. This created a dilemma: not window ventilation, to be afraid of hitting; Fenestration ventilation, afraid to come blowing cold air sick. The General Hospital of the PLA Air Force and former head nurse Xiu-Qing Liu remind you: more winter window ventilation, but also to pay attention to methods.

“According to statistics, China annually due to indoor air pollution caused by the death toll to 111,000. Winter dry air, microbial reproduction and dissemination of speed, the human respiratory resistance decreased more susceptible to respiratory diseases. “Xiu-Qing Liu said that the ventilation window, should frequency, time, personnel and indoor environmental conditions.

First, preferably in a day early, middle and late ventilation window three times. “Some people think that the number of fenestration better, in fact, not the case, because frequent window will reduce the room temperature, the elderly and children susceptible to diseases.”

The second, smaller room, outdoor cold wind or more circumstances, the time window should be shorter; Larger rooms, outdoor warmer than the wind or the circumstances fenestration time should be longer. A 80-square-meter room for example, in the absence of wind or breeze conditions window about 20 minutes can be reduced to 60% of pathogenic microorganisms.

Third, if the road is outdoors, more pollutants will require changes in the time window. “Some early morning slightly, at some slightly delayed for less time in the car window ventilators. If a sandstorm weather, preferably in a window of circumstances, opening a small window. And the use of humidifier, wet spray, or in a bowl of warm water release to increase air humidity, ash all dust and microorganisms sink. ”

Fourth, the elderly and children in the best clothes, and before the window, window due to the temperature plunged to patients. If there is ill patients require careful fenestration, as ultra-violet disinfection lights to clean up the air.

It must be noted that not because of the indoor temperature fell to 16 ° C and fenestration under control in 16 ° C -24 ° C is the best.

As the radiation appliances, we will soon think of computers, televisions, microwave ovens, but often overlooked smaller hairdryer, in fact, it is the “king of radiation.”

Ordinary home of the 1000 hairdryer, radiation 350mG value of about (mG: mg is the magnetic field intensity Andean units), and televisions and computer monitors, radiation values are about 45mG and 100mG, far less than the amount of radiation hairdryer. Because of the use of hair-dryer, radiation than other distance from the head to near electrical, radiation hazards self-evident.

“Hairdryer is indeed high radiation household appliances, especially in the opening and closure of the largest radiation, the greater power and greater radiation.” Architectural Design and Research Institute of China’s standards, deputy director of engineering design, electrical design director Huangjiekai, electromagnetic radiation of the electromagnetic wave is a composite body life activities include a series of biological activity, these organisms on the environment, the electromagnetic wave is very sensitive, so the electromagnetic radiation on the human body can be affected and damage.

When the human body by electromagnetic radiation, and the spirit will cause central nervous system dysfunction, primarily manifested as dizziness, fatigue weakness, memory loss, anorexia, insomnia, forgetfulness and other symptoms of subhealth.

The correct use of the hair-dryer

Because of the use of hair-dryer, radiation sources - hair-dryer motor parts from the back-end close to the head, it is easy because of electromagnetic radiation caused dizziness, fatigue, hair-dryer in use, should maintain the correct methods, such as open and closed hairdryer, as far away from the head; When used, the best head will remain with the vertical hair-dryer; Do not use for a long time, the best intermittent stops.

Domestic small coup against radiation

Apart from the hair-dryer and other appliances radiation also can not “underestimate” Huangjiekai director of several anti-radiation coup appliances, such as computer operation, from the display at least 30 centimeters above the machines transient electromagnetic radiation largest and should be avoided; When watching television, preferably from TV 3 meters, away from the TV immediately after the shutdown; the use of microwave ovens, at least 0.5 meters from the furnace, Furnace Door eyes do not see, not in a long time at Front, food removed from the furnace, the best first-eating minutes; Blanket for pregnant women, children, elderly damage the largest anti should, as an equivalent to pad itself electromagnetic field, even off the power, radiation will still disturb the body’s natural electric field.

In their daily diet, we should eat more carrots, tomatoes, kelp, lean meat, animal liver, rich in vitamin A, vitamin C and protein food, strengthen the body’s ability to resist electromagnetic radiation.
