In order to enhance physical fitness, improve the human body's adaptability to climate change and cold resistance.

You should supplement more water and water-soluble vitamins B and C, and eat more apples and green leafy vegetables at ordinary times, which will help to promote fluid production, prevent dryness, nourish yin and moisten the lungs. But don't be greedy for fruits and vegetables in autumn, so as not to damage the spleen and stomach. It is also necessary to use less hot and dry foods such as onions, ginger, garlic, leeks and peppers, otherwise the summer heat will be unclear and the autumn will be dry, which is easy to suffer from fever. Eating some high-protein foods, such as milk, eggs and beans, can make people's brains produce a special substance, which can eliminate depression.

Outing and mountaineering activities can enhance the human body's respiratory and blood circulation functions, increase people's vital capacity and myocardial contractility. Especially for people who live in downtown areas for a long time, hiking in autumn can absorb more negative oxygen ions in the air, which has a good nutritional and soothing effect on people's nervous system and effectively resist the invasion of autumn dryness and cold.
