August 19, 2025 marks the end of the dog days of summer, meaning the most unbearable heat of the year is finally coming to an end.

After this period, summer truly begins to transition into autumn, and the focus of health maintenance should also be adjusted accordingly.

Large Temperature Differences Between Day and Night for Over 30 Days After the Dog Days

Why is this period so special?

As the saying goes, "cool in the morning, scorching by noon." From the end of the dog days to the autumn equinox (August 19 to September 23 this year), not only do the temperature differences between day and night increase, but fluctuations in temperature also become more frequent.

The so-called "Indian summer" often occurs during this time, posing greater challenges to the body.

● The alternating cold and heat stimulate the contraction of blood vessels, which can be taxing on the cardiovascular system and other organs.

● After a hot summer, the digestive function may weaken, and the body may experience significant exhaustion.

● The dry climate can affect the lungs, making it easier to catch respiratory conditions.

3 Things to Avoid After the Dog Days

Avoid Early Morning Exercise

In early autumn after the dog days, the temperature difference gradually widens. Some people go out for exercise as early as 4 or 5 a.m., when the body is more susceptible to the cold. This can cause a rapid rise in blood pressure, which is already higher in the morning, potentially increasing the risk of cerebrovascular issues.

Avoid Overindulging in Cool Temperatures

After the dog days, mornings and evenings become cooler. It is important to keep warm and add clothing in time, paying special attention to covering the neck, back, and feet, as these areas are rich in blood vessels. The cool autumn air may stimulate rapid blood vessel contraction, which could lead to discomfort.

Avoid Staying Up Too Late

After the dog days, many people tend to feel fatigued, a phenomenon often referred to as "autumn fatigue." To alleviate this, it is advisable to sleep earlier, ideally going to bed by 10:30 p.m. Waking up early and increasing sleep by about an hour compared to summer, or taking naps, can help combat fatigue.

How to Nourish the Body After the Dog Days?

After the hot and humid summer, which may lead to energy depletion and fluid loss, many people experience loss of appetite, weakened digestive function, and reduced vitality. As the weather cools after the dog days, appetite gradually improves. In ancient times, people would take this opportunity to nourish their bodies and regain strength, a practice known as "autumn replenishment."

After the dog days, it is beneficial to focus on balanced nourishment to help the body prepare for the changing season.

Nourish Yin and Combat Dryness

Autumn is characterized by dryness. After the dog days, priority should be given to nourishing yin and combating dryness. Foods that help moisturize and soothe the body, such as lingzhi and white fungus soup, can be beneficial. Lingzhi is traditionally known for supporting lung health and calming the mind, making it helpful for nourishing the heart and lungs and promoting restful sleep.

According to traditional practices, autumn is associated with "harvesting." It is suggested to include acidic foods in the diet, such as hawthorn, black plum, pomegranate, grapes, and kiwifruit, to help gently consolidate lung energy.

Moderate Nourishment

Health maintenance after the dog days emphasizes "dispelling dampness without depleting yin, and moisturizing without exacerbating dampness," aiming to find a balance. In northern China, people often eat dumplings after the dog days. Resembling ancient currency, dumplings symbolize "inviting fortune." In southern China, people prefer lighter soups, such as old duck soup, which helps dispel summer heat while nourishing yin.

Stay Hydrated

Temperatures can still be high after the dog days, so it is important to stay hydrated.

If sweating heavily, increase water intake appropriately. When feeling thirsty, drink slowly and steadily, taking small sips at a time.

The dog days are over, and cool breezes are on their way.

Adapt to the season with a light and moistening diet.

Incorporate lingzhi and adjust your mood.

Quietly await the arrival of autumn
