One of the most important characteristics in summer is hot, and in this period, we need to pay attention to some health knowledge. The health care in the summer is the same as that of other season. Usually the health care of summer is around hot, then how can we keep health? In the summer, when people go out, they will absorb a lot of heat and the pores if human skin is in a state of “open”, but immediately shower will rapidly close the body pores, so that the heat cannot be distributed to outside, but stay in vivo, which can easily cause hyperthermia; at the same time, when you take cold bath, due to the rapid shrinkage of brain capillaries, it also easily lead to insufficient blood supply to make people dizzy. In serious cases, it can lead to shock. Therefore, when you go back home from outside in the summer, you should let yourself sweat and after the sweat send out, and then you can take some cool measures. Moreover, in the hot summer, when we go out, we always wear sunglass to protect our eyes. However, do you know how to choose correct sunglass? It is not that the color of sunglasses is the darker the better. If the lens color is too deep, it will seriously affect visibility, and the eyes are vulnerable to injury because of difficult to see things, ad it cannot play the role of eye protection. Therefore, the experts suggest that the standard of choosing sunglasses in the summer is: lens should be able to pass through the 15 percent to 30 percent of visible light; gray and green is the best way, which not only can resist ultraviolet and the clarity of watching objects is better, and the color change of perspective external objects is also the smallest. Furthermore, medical meteorologists found by experiment that to constantly adjust the room temperature can make human physiological thermoregulation mechanism constantly in tension, so as to gradually adapt to the rapid changes in temperature, and improve people's ability to protect them, and will not get frequent colds or suffer other bedroom illness. Therefore, in the beginning of the use of air conditioning for such adjustment, the temperature change of the amplitude of the entire room should be controlled at 3? to 5?; Two weeks later, the amplitude can be gradually increased to 6? to 10?. The temperature variation is not too sudden, but to smoothly increase or decrease, and every adjustment is preferably 1? to 2?.
