How many suitable winter heating room temperature?

    Cold winter quietly but go to, a lot of families are using all kinds of heating equipment, although the design is different, but are facing a problem: the set and how many degrees? Below we will with air conditioning as an example to introduce the choice of indoor temperature.
 
    The heating temperature is unfavorable and exorbitant When indoor temperature up to 22 ℃ above, will make the air very dry, hot environment can damage human body fluids, jin qi, make a person feel whole body heat, eyes, ears, mouth, nose and throat, dry skin and discomfort. If indoor temperature is too high, for a long time will affect the person's body temperature adjustment function, causes a high body temperature, blood vessels to relax, to speed up the pulse, heart rate speeds up, people would god exhausted power, which feature, thinking slow, poor memory. Indoor temperature is too high, furniture, stone material and toxic gas in the interior decoration to release a quantity to also will increase, and the winter most room doors and Windows closed, harmful substances are more likely to accumulate indoors, also can affect human body health.
 
    Winter heating temperature also shoulds not be too low Sit when the temperature is less than 12 ℃, 80% of people will feel cold, 20% active people can feel cold, so the hygiene 12 ℃ as the lower limit of the building thermal environment. If indoor temperature is too low, it will make human body metabolism function drops, breathing slowed, skin vasoconstriction, respiratory tract mucous membrane resistance is abate, easy to cause colds and other respiratory diseases. And because the stimulation of cold on the body, increased sympathetic nervous system excitability, catecholamine secretion increased in the body, can make human body blood vessels constrict, heart rate, cardiac workload increases, oxygen consumption increased, serious when myocardial ischemia hypoxia, cause angina pectoris, so pay particular attention to the winter heating in patients with coronary heart disease.
 
    Room temperature should vary from person to person Young metabolic ability, adjust their own ability is stronger, when cold to stimulate the skin blood vessels to a large degree of shrinkage to reduce body heat loss, therefore, the lower the temperature, more appropriate. The elderly physiological function to drop, aging skin, blood vessel elasticity is poorer, and low metabolism, high temperature more appropriate. Infant body are immature, low thermoregulation ability, should pay attention to keep warm, but infant metabolism, and do not overheat. So, from the comfort, young people can in 12 ~ 14 ℃, the elderly in 16 ~ 18 ℃ more appropriate.
 
    Room temperature should be lower outdoor temperature adjustment according to the weather, indoor temperature setting should be lower, because the bigger the temperature difference between indoor and outdoor health more adverse to the body. People in quenching heat environment, can stimulate respiratory tract mucous membrane, easy head cold. For the old man and the risk of high blood pressure, indoor and outdoor temperature difference cannot too much more. Because indoor temperature is too high, the human body vasodilation, if suddenly in the outdoor, encounter cold stimulation, vascular contraction, suddenly for the elderly and patients with high blood pressure of these vascular elasticity bad people, it is easy to appear the brain blood circulation obstacle, easy to cause a stroke.
 
    Overall, according to the study, the body is the most suitable room temperature 18 ℃, should be a good person's state of mind at this time, the efficiency high, the most agile thinking.
