Tell you meter high indoor temperature in winter is not good!

The weather is very cold in winter, many people are not willing to come out, and indoor air conditioning temperature is very high, but how high indoor temperature is appropriate? According to physiological research, when the indoor temperature is too high, can affect the person's body temperature adjustment function, due to poor heat dissipation caused by the temperature, speed up vasodilatation, pulse, heart rate speed. In winter, if often maintain indoor temperature above 25 ℃, will god exhausted power, heads up, thinking slow, poor memory. At the same time, because indoor and outdoor temperature difference, the body is difficult to adapt, prone to colds. If indoor temperature is too low, it will make human body metabolism function decline, slow pulse, respiration, skin vasoconstriction, overstrain skin, respiratory tract mucous membrane resistance is abate, easy to cause respiratory diseases. As a result, the scientists to & other; Cold tolerance & throughout; The lower limit of temperature and & other Heat tolerance & throughout; The upper limit of temperature, as 11 ℃ and 32 ℃ respectively. While pay attention to the indoor temperature regulation, still should pay attention to indoor humidity. In the summer, when the indoor humidity, can inhibit the body heat, make the person feels very hot, be agitated. In winter, when the indoor humidity is big, will accelerate the heat transfer, make the person feels cold, depression. Indoor humidity is too low, because of the upper respiratory tract mucous membrane water a lot of loss, people will feel dry, dry mouth, tongue and throat sore, hoarse and nasal bleeding, etc. , and susceptible to colds. So, the experts research thinks, limit should not be more than 80% relative humidity, lower limit should not be less than 30%. Simple sense of human body, however, were not influenced by the temperature or gas wet two kinds of factors, but a result of the combined action of the two. Determination through the experiment, the most pleasant indoor temperature and humidity are: winter temperature is 18 to 25 ℃, humidity is 30% to 80%; Summer temperature is 23 to 28 ℃, humidity is 30% to 60%. Within the scope of this comfortable accounted for more than 95%. In the air-conditioned room, room temperature is 19 to 24 ℃, humidity is 40% to 50%, people would feel most comfortable. If considering the temperature and humidity on the influence of the thinking activity, should be the most suitable room temperature 18 ℃, humidity is 40% to 60%, at this point, the person's state of mind is good, the most agile thinking, high working efficiency.
