# Health Guide for Mangzhong (Grain in Ear)
**Mangzhong** (Grain in Ear) is the 9th of the 24 solar terms and the 3rd term of summer. During this period, midsummer officially begins, characterized by rising temperatures, increased rainfall, high humidity, sweltering heat, and frequent thunderstorms. In nature, Yang energy is at its peak, and all living things flourish. Human bodies also respond to these natural changes: Yang energy floats to the surface, pores open for perspiration, and dampness easily invades the body. Therefore, health maintenance during Mangzhong should focus on **"clearing heat, dispelling dampness, and nourishing the heart to calm the mind."**
# # I. Daily Routine: Early Rising, Late Sleeping, and Scientific Cooling
During Mangzhong, days are long and nights are short. It is appropriate to sleep a bit later and wake up earlier to align with the natural rhythm of Yang energy. However, "sleeping later" does not mean staying up all night; it is recommended to be in bed before 11:00 PM.
# # # 1. Moderate Napping
Due to the high heat and increased energy consumption, the body easily tires. A moderate noon nap is recommended to replenish physical strength and restore energy. The nap should not be too long, generally between 30 minutes to 1 hour.
# # # 2. Scientific Use of Air Conditioning
Many people are reluctant to leave air-conditioned rooms to avoid the summer heat, but while air conditioning brings coolness, it can also have negative effects.
* **Temperature Control:** The indoor temperature should ideally be kept between **26°C and 28°C**. The minimum temperature should not fall below 20°C, and the difference between indoor and outdoor temperatures should not exceed 8°C.
* **Ventilation:** If staying in an air-conditioned room for a long time, ensure regular ventilation and strictly prohibit smoking indoors.
* **Outdoor Activity:** People who live and work in air-conditioned environments should spend at least 4 hours outdoors daily.
* **Special Groups:** The elderly, the physically weak, and patients with hypertension should avoid staying in air-conditioned rooms for extended periods.
# # II. Dietary Habits: Light Food and Salt Supplementation
During Mangzhong, the diet should be light, focusing on foods that clear heat, dispel dampness, and strengthen the spleen to aid digestion.
# # # 1. Moderate Salt Supplementation
High temperatures lead to heavy sweating, causing the body to lose salt and potentially leading to electrolyte imbalances. Therefore, it is advisable to moderately supplement salt in the daily diet or drink lightly salted water to maintain the body's functional balance.
# # # 2. Recommended Foods
* **Grains:** Barley (Job's tears), adzuki beans, Euryale seeds (Qianshi), and mung beans for strengthening the spleen and dispelling dampness.
* **Vegetables:** Winter melon, cucumber, luffa, bitter melon, tomatoes, celery, and lettuce for clearing heat and reducing water retention.
* **Fruits:** Watermelon, cantaloupe, peaches, and plums for promoting fluid production and hydration.
* **Proteins:** Duck meat and fish for light, non-drying nourishment.
# # # 3. Dietary Taboos
* **Barbecue:** Increases the burden on the spleen and stomach and breeds damp-heat.
* **Iced Drinks:** Damage the Yang energy of the spleen and stomach, potentially causing diarrhea and abdominal pain.
* **Sweet Pastries:** Excessive sweetness can foster internal dampness.
# # III. Exercise: Gentle Activity and Heat Avoidance
Exercise should be gentle to avoid excessive sweating, which can deplete Yang energy. It is best to exercise during the cooler hours of early morning or evening. Recommended activities include walking, Tai Chi, Baduanjin (Eight Brocades), and Yoga. Always replenish fluids after exercise, but avoid ice-cold water. Also, pay attention to sun protection.
# # IV. Emotional Well-being: "A Calm Heart Keeps You Cool"
The summer heat can make people irritable and increase "heart fire." Health maintenance during Mangzhong emphasizes "a calm heart naturally keeps you cool." Maintain a cheerful and peaceful state of mind through activities like listening to music, reading, playing chess, or fishing. In Traditional Chinese Medicine (TCM), "heat easily enters the heart," so emotional regulation is vital for cardiovascular health.
# # 五. Acupressure and Meridian Regulation
Mangzhong is a key time for "treating winter diseases in summer." Stimulating specific acupoints can help expel cold and dampness.
* **Zusanli (ST36):** Strengthens the spleen and stomach, enhances immunity.
* **Yinlingquan (SP9):** Dispels dampness and promotes urination.
* **Fenglong (ST40):** Resolves phlegm and dampness.
* **Shenmen (HT7):** Calms the mind and regulates heart energy.
# # VI. Other Precautions
# # # 1. Skin Hygiene
High temperatures and humidity can lead to the growth of bacteria and fungi, causing skin issues like eczema or sweat spots. It is recommended to bathe and change clothes frequently to keep the skin dry. Using warm water for bathing helps keep sweat glands clear and expels damp-heat.
# # # 2. Preventing "Summer Fatigue" (Kuxia)
To combat loss of appetite and lethargy common during this term, eat bitter-tasting foods (like bitter melon or lotus seed hearts). These help clear heat and stimulate the appetite.
# # # 3. Clothing Choice
Wear loose, breathable, and absorbent cotton or linen clothing. Change sweat-soaked clothes promptly to prevent dampness from entering the body through the pores.
