blisters, ulcers. If you stay too long time in a cold environment, not only damage skin, may also cause systemic disease. In a cold environment, significantly the incidence of diseases such as heart
disease, stroke, flu, frostbite, arthritis will increase. In winter
tourism, the weather such as low temperature and humidity, high
barometric pressure, and fast wind speed is very common.

increase the metabolism, and when travel consumes a lot of physical
strength, only to increase the intake of nutrients to meet the needs
of the human body. In the diet of tourists in the winter, the
protein, carbohydrates and fats the three major nutrients, and intake
