Why do the dog days last for 40 days?

The dog days start from the third Geng day after the summer solstice, and last for ten days, for a total of 30 days. However, there is an agreement: that is, add one more dog day after autumn. This means that if it is not the beginning of autumn after 30 days, one more volt will be added, so it will be 40 days in total.
The "伏" in "三伏天" refers to "伏邪".
The "hidden evil" refers to the "six evils" which is a term used by people in ancient times, namely the so-called "six evils" (referring to "wind, cold, heat, dampness, dryness and fire"), among which is the heat evil. In the summer, the heat will gradually hide deep in the body without being noticed. If the summer heat is not eliminated, in the autumn, the fire evil will overcome the metal and damage the lung qi, causing a decrease in human immunity and leading to diseases such as colds, coughs, and fevers. After entering winter, these diseases will recur, "... in autumn, there will be malaria, few people will recover, and in winter, there will be severe illness."
Therefore, Huangdi Neijing clearly points out that one should "let the qi be released, as if what one loves is outside". Don't hide in an air-conditioned room for fear of sweating. Cold drinks not only fail to relieve the heat, but will also damage the spleen and stomach.
The "Three Fu" refers to the first, middle and last Fu, which is approximately from mid-July to mid-August. After the summer solstice, although the days become shorter and the nights become longer, the days are still longer than the nights. The ground still absorbs more heat than it emits every day, and the temperature near the ground becomes higher day by day. During the "dog days" period, the ground absorbs more heat than it emits, and the weather is the hottest. Later on, the heat absorbed by the ground began to be less than the heat emitted by the ground, and the temperature slowly dropped. Therefore, the hottest time of the year usually occurs during the "Three Fu" period during the summer solstice.

What precautions should we take during the dog days of summer?

Expel summer heat evil <br /> The dog days are when yang is strong and yin is weak, and it is also a period when evil qi easily rises. During the hot summer, heat evil lurks inside the human body, which can easily cause people to feel weak and have a poor appetite. In severe cases, people may suffer from heatstroke, which can cause dizziness, fatigue, and slow reaction, affecting their health. To get rid of summer heat, we must pay attention to cooling off and removing dampness, and pay attention to some dietary health care. Cold drinks are not suitable for cooling off, as they will damage the spleen and stomach, and will make things worse for people who suffer from the summer heat. Green tea is a great product for relieving heat. It not only removes dampness, but also helps improve gastrointestinal digestion and relieves the mental fatigue caused by "summer naps".
Treat winter diseases in summer <br /> Traditional Chinese medicine talks about “treating winter diseases in summer”. For people with insufficient yang energy, cold body, and weak lung qi, the dog days are the best time for effective conditioning and treatment. During the dog days, Yang energy is at its peak, which can help patients “build up their foundation” to support their Yang energy, making it sufficient and vigorous and enhancing their disease resistance. In winter, the incidence of disease can be reduced or eliminated, thus achieving “winter disease treatment in summer”.
People who like fire in their horoscope can improve their fortunes in due time <br /> Summer is fire in the five elements. Although the dog days are hot, it is also the time when fire is extremely strong. This is a good thing for people who like fire in their horoscope, because they can take advantage of this time to improve their fortunes. Therefore, those who have fire in their horoscopes should seize the opportunity during the dog days of summer. If you need to confess your love, do so to the person you like. If you need to change jobs, choose the right time to start a new life. In short, people who like fire can achieve something if they seize the opportunities during the dog days of summer.
People who are afraid of fire should pay attention to regulating their body and mind <br /> Compared to people who like fire, people who are afraid of fire in their horoscopes due to strong fire and dry earth should pay attention to regulating their body and mind during the dog days, and learn to regulate their emotional fluctuations and restless mentality. Pay attention to your physical health, especially your heart and cardiovascular health. At the same time, special attention should be paid to the use of electrical appliances and gas, especially in thunderstorms, try to avoid outdoor activities or travel to prevent any adverse effects.
