In the four seasons of the year, summer is the season when yang energy is at its peak, and the climate is hot and vigorous. For people, this is a period of vigorous metabolism, when the body’s yang energy is developed externally, and the voodoo yin is developed internally, and the qi and blood are also active on the surface of the body. Therefore, in summer, we should pay attention to the protection of the body’s yang energy, to prevent excessive greed for cool due to summer heat, thus harming the body’s yang energy. This is the so-called “spring and summer nourishment of Yang”. Specifically, we should pay attention to the following aspects: First, to sleep late and get up early: in line with the changes in the natural world Yang Sheng Yin Decay. That is to say, get up earlier every day, in order to comply with the fullness of Yang Qi and Sheng real; later to go to sleep, in order to comply with the lack of Yin Qi. In summer, there is a lot of sunshine, so don’t be disgusted by the long day and the heat, but still be properly active to adapt to the summer “nourishing long” gas, and get up early to receive sunshine and fresh air in the morning, which is beneficial to the organism. Due to the late sleep and early rise in summer, there is a lack of sleep. Especially the elderly, sleep is not real, easy to wake up characteristics, more likely to fatigue, so the summer nap is an important method of health and fitness, both to compensate for the lack of sleep at night, more responsive to the physiological characteristics of the human body conservation needs. Nap time is generally appropriate to 1 hour, and pay attention to the sleep position, can lie flat or side, and in the abdomen covered with a towel, so as not to stomach and abdomen cold. Although the nap is short, but it is conducive to make up the necessary sleep time, so that the body to get sufficient rest, so that the recovery of neurological functions, physical strength, fatigue elimination, enhance the body’s protective function, more effective work and labor. Second, to prevent the heat to take cool: the summer season, the weather is hot, in order to relieve the heat, it is necessary to take appropriate measures to prevent heat and cool down. However, if the greedy cool excessive, stay in the air-conditioned room for a long time, or the fan does not leave the body, or sleep overnight, are very detrimental to health. Because of the summer heat outside the steam, the body sweats a lot, the whole body epidermal vascular expansion, suddenly by the cool breeze, often causing vasoconstriction, sweating immediately stop, resulting in the body heat production and heat loss of balance, leading to the occurrence of disease. The temperature difference between indoor and outdoor is not easy to be too large, to not more than 5 ℃ is good, indoor temperature should not be less than 25 ℃. Third, to protect skin care: summer hot sun, strong sunlight will have a series of adverse effects on the human body, the sun’s ultraviolet rays can not only make the skin tan, but also lead to cataracts, sunburn skin, skin cancer. In addition, prolonged exposure to the sun, the human body temperature regulation out of balance, so that the body a lot of heat storage, water and salt metabolism disorders are also prone to heat stroke. Therefore, when you go out in summer, you should wear a sun hat and sunglasses to reduce the damage of ultraviolet rays on the skin and eyes. Due to the hot summer climate, the body is prone to sweating, attention should be paid to the choice of skin care products, such as sunscreen creams, creams, honey lipids, can eliminate the premature aging of the skin, flower lotion, talcum powder, prickly heat powder, perfume, etc. can not only protect the skin, and can refresh the mind, but also give a sense of fragrance and beauty. Fourth, to emotional cheerful: in the spiritual conditioning, Chinese medicine believes that “summer to put”, that is to say, summer spirit to be abundant, full, emotionally outward, because only the gods are sufficient to the body’s functions and coordination, so that the organism’s qi smooth, ventilate freely, emotions outward, showing a strong interest in external things. And to do “Hua Ying into the show”, that is, the spirit of the Ying Hua to adapt to the summer gas to become its show beauty. Do not get angry, so that the body can be exhaled Yang Qi. Therefore, the spirit of summer conditioning, should be in line with the law of nature “growth”, take the initiative to regulate the mood, maintain a quiet and happy state of mind, clear and broad-minded, so that the mind and soul maintenance. Five, to move the combination of static: summer body consumption, exercise regimen should be a combination of static and dynamic, can choose to swim, fishing, walking, slow full, but the amount of exercise to moderate, not too fatigue. And should not be in the hot sun or high-temperature environment for exercise, it is best in the early morning or evening when the weather is cool outdoor exercise, exercise should wear loose, comfortable, sweat-absorbing and good breathability of cotton fabric is good, to facilitate the body heat dissipation. Summer outings, especially the seaside and mountainous areas, that is, summer heat, refreshing, but also to achieve healing, exercise, and promote physical health. Six, to diet and hygiene: summer human metabolism enhanced, nutrition consumption increased. Summer people’s appetite is reduced, poor digestion and absorption, can lead to disorders in the body’s nutrient metabolism, and even cause the corresponding nutrient deficiencies and other diseases. For this reason, the summer diet should be supplemented with sufficient protein, vitamins, water and inorganic salts to protect the body’s needs. At the same time, it is important to eat more foods that can clear heat and dampness, such as watermelon, bitter melon, peach, umeboshi, grass mold, tomatoes, cucumber and green beans. But raw fruits and vegetables must be cleaned to prevent summer intestinal infections. Fish, eggs, meat and other food should pay attention to preservation and preservation. Food utensils and cooking utensils such as plates should be used separately for raw and cooked food, not mixed, and pay attention to disinfection. If possible, you can eat more garlic, which can be sterilized and can help digestion, improve appetite, seasoning and relieve the summer heat.
