Why frost first, not frost?
Because "frost" is a manifestation of cold weather and large temperature difference between day and night, it is named "first frost", which means "sudden drop in temperature and large temperature difference between day and night". On the national average, "first frost" is the season with the largest temperature difference between day and night in a year. The first frost solar terms are characterized by cold weather in the morning and evening, hot weather at noon, large temperature difference between day and night, and obvious autumn dryness.
Matters needing attention in the first frost season:
1. Pay attention to diet: Try to keep your diet light in the first frost. Especially don't put too much salt in food. Because too much salt makes people feel thirsty, you need to drink a lot of water to relieve it. Long-term intake of salt will lead to edema and increase the burden on the kidneys.
2. Pay attention to gastrointestinal health: After the first frost and solar terms, try to choose warm food, try to eat less irritating food, protect gastrointestinal health to the greatest extent, and avoid gastrointestinal problems leading to decreased immunity.
3, pay attention to the mood: because the weather is getting colder, plants turn yellow, which is more likely to cause people's worries and make people depressed. During the holiday, you may wish to climb the mountain with three or five friends to enjoy the leaves. This will not only breathe fresh air, broaden your horizons, release the emotions of tension, anxiety and depression, but also expand social contacts and eliminate psychological loneliness.
4. Pay attention to adding clothes to keep warm: In the first frost season, the temperature may suddenly drop, and the temperature difference between day and night will increase by more than 10℃. Our skin and respiratory system cannot adapt to such changes well, so we should pay attention to adding clothes in the morning and evening and keep warm.
