Physiologists have proved that in the environment of 15 ~ 18℃, people have quick thinking, strong memory and the highest working efficiency; When the temperature is lower than 15℃, people will feel slack and work efficiency will decrease. When the temperature drops below 4℃, the body's heat can't make ends meet, and the body's disease resistance declines. At this time, the incidence and mortality of stroke, angina pectoris and other diseases increased significantly; When the ambient temperature is 30 ~ 35℃, the blood circulation of human body is accelerated and the metabolic capacity is strengthened. At this time, the heat in the body should be discharged in time, otherwise the body temperature will rise, people will be tired and mentally retarded.
In view of the above advantages and disadvantages, we should adjust the ambient temperature according to the data provided by scientists to maintain our health.
