There is a folk proverb called "the morning is the chill of early autumn, and the evening is the heat of early autumn". People think that if beginning of autumn time is in the morning, the weather will be cool; If beginning of autumn time is after afternoon, it will be hot for some time. This statement should be based on the life experience of working people, but there is no reliable scientific basis to prove it.

Matters needing attention in autumn:

1, pay attention to clothes to prevent colds.

Autumn is different from summer. The temperature in the morning has started to be a little low. Generally, you sweat more when you exercise. If you are not careful, you are in danger of catching a cold. Therefore, don't wear light clothes to go outdoors as soon as you get up, but give your body a time to adapt. Especially for the elderly, don't get up immediately after waking up in the morning, because the intervertebral disc of the elderly is slack, and suddenly changing from lying position to standing position may cause back sprain. Older people with high blood pressure and cardiovascular diseases should be more careful when getting up. They can stretch their bodies and joints on the bed and get out of bed after a short rest.

2. Replenish water in time to prevent autumn dryness.

From hot and humid summer to autumn, the climate suddenly dries up and the temperature drops a lot. It is easy to accumulate some heat in the human body, and the humidity in the air decreases in autumn, which is easy to cause symptoms such as dry throat, shortness of breath, chapped lips, nosebleeds and dry stool. In addition, the water lost during exercise will aggravate the body's response to water shortage. Therefore, after exercise, you must drink more boiled water, eat more soft foods such as pears, apples, milk, sesame seeds and fresh vegetables, or drink more foods such as rock candy pear water and winter melon soup in order to maintain the normal secretion of upper respiratory mucosa and prevent sore throat.

3. You can't exercise on an empty stomach in the morning.

Some people are used to getting up in the morning to exercise first, and then having breakfast after exercise, which is not good for their health. Because the body consumes a lot of energy during exercise, after a night of digestion and metabolism, the food eaten the night before has been digested, and there is basically no energy in the body to consume. If you are still exercising when your stomach is empty and hungry, it is easy to have hypoglycemia. It is more serious for the elderly. Therefore, you should drink some sugar water or eat some fruit before exercise after getting up, so that your body can get some starting energy, which will be more conducive to your health.

4. It is not advisable to exercise when you are full of food and drink.

The living habits of modern people are rarely "work at sunrise and rest at sunset". They sleep late at night and have a lot of work in the morning. Many people don't have time to exercise in the morning, so some people set the exercise time after dinner. It is good to keep exercising, but it is unhealthy to exercise immediately after meals, even if it is a walk. This is because the blood circulation in the digestive system is greatly increased after meals, while the blood circulation in other parts of the body will be relatively reduced. If you start exercising immediately, the process of digestion will be blocked and the gastrointestinal tract will easily get sick. So it is better to exercise for 30 minutes after meals.

5, adjust diet to enhance physical strength

In autumn, when the weather turns cold, people's appetite will be great and their calorie intake will increase greatly. Coupled with the pleasant climate, people get enough sleep. In order to welcome the arrival of winter, the body will actively store fat to keep out the cold. Therefore, the body absorbs more calories than it discharges. Therefore, in autumn, we should not only eat more nutritious things to enhance our physical strength, but also be careful about gaining weight, especially those who are obese themselves. Pay attention to eat more low-calorie diet foods, such as adzuki beans, radishes, bamboo shoots, coix seed, kelp, mushrooms and so on. And don't eat greasy food containing heavy oil, so as not to increase the burden on the stomach, and it will also increase the body temperature and blood sugar, which will make people feel depressed and tired.
