The popularity of various air-conditioning equipment, so that the original summer common wind-heat cold and heatstroke less, and winter is easy to get the wind-cold cold but significantly increased, because many doctors and patients on the summer cold still lack sufficient knowledge, so that the cold cold cold this anti-seasonal disease can not be timely and effective treatment, leaving a lot of after-effects. Air conditioning increases the temperature difference between indoor and outdoor. And people are constant temperature creatures, the increase in temperature difference between indoor and outdoor environment will inevitably cause the body to adjust the burden of maintaining constant temperature, thus harming the body’s temperature control function, that is, the Chinese medicine said that the righteousness is damaged, the ability to protect the body against external evil is reduced, the body is easy to be attacked by external evil and lead to external sensation. In other words, as the ancients said, “where evil comes together, its qi will be deficient”. Secondly, the body excretes tangible waste through the stool; and invisible turbidity through the skin and breathing. Excessive greed for cold, so that the pores are closed for a long time, the body can not be exhausted, the turbid gas increased, the external drainage is blocked, the body’s adjustment function decreased, but also easy to external disease. In addition, the hot summer, some people like to eat a lot of popsicles, ice cream or frozen drinks, which is also a cause of cold, which has a great impact on health, that is, as the ancients said, “the form of cold drinking cold is hurt lungs. The prevention of summer colds is actually very simple, first of all, we must control the mouth, do not crave cold food and cold drinks all day and night, pay attention to a light diet, you can eat less and more meals, which helps digestion and speed up the discharge of turbidity; the second is not to lower the indoor temperature too low, resulting in the temperature difference between indoor and outdoor too large.

With the development of the society and the improvement of the quality of life, the number of patients suffering from heat stroke has relatively decreased, at most the weak people with slight dizziness and nausea, but the number of diseases caused by cold has increased. Traditional Chinese medicine is concerned about the “Heavenly Man corresponding”, the body should be metabolized faster in summer, often sweating. Most of the people who get cold in summer are sweating heavily when they enter the room with low temperature, and the skin pores are closed at once. Whether it’s a hot cold or a cold, you need to identify the evidence to treat it, the wind-heat cold to dissipate heat, and the cold to disperse cold.
