This year's Great Heat is in its early stages, with a mix of dampness and heat, which can easily lead to weakened spleen and stomach function, decreased digestive ability, and other problems. On July 23rd, experts put forward many suggestions on the topic of heatstroke prevention and health preservation at the "Seasonal Solar Terms and Health" press conference held by the National Health Commission. For health enthusiasts who enjoy "sun drying their backs during the hottest days of summer", Zhang Zhenpeng, chief physician of Guang'anmen Hospital of the Chinese Academy of Traditional Chinese Medicine, said that the Great Heat is a good season for "nourishing yang", and sun drying their backs is one of them. But he reminded that sunbathing is not suitable for everyone, especially those with weak constitution, advanced age, or skin allergies to ultraviolet rays, those with excessive yang energy or yin deficiency and yang hyperactivity constitution, as well as those with underlying diseases such as hypertension, coronary heart disease, and hyperlipidemia. What are the precautions for "sunbathing on the back in summer"? Zhang Zhenpeng introduced that sunbathing requires choosing the appropriate weather and time period. Start with 5-10 minutes and gradually increase to 15-30 minutes per session after adaptation, 2-3 times a week. After sun exposure, it is necessary to replenish water in a timely manner, avoid taking cold showers, blowing fans or air conditioning, and entering air-conditioned rooms with large temperature differences. The hot weather during the 'Sanfu' period often causes people to experience inexplicable distress and other problems. For this type of "emotional heatstroke", Zhang Zhenpeng explained that traditional Chinese medicine believes that the physiological characteristics of the liver are to regulate the flow of qi and promote the rise of qi. The liver is closely related to the regulation of emotions, and long-term negative emotions may lead to liver qi stagnation or excessive liver fire, affecting the normal function of the liver in regulating the flow of qi and promoting the rise of qi. In addition, the relationship between the liver and spleen is close. When the liver's drainage function is imbalanced, it can lead to weakened spleen and stomach function and decreased digestive ability, resulting in loss of appetite, fatigue, and further worsening of liver disease. Liver disease patients can adopt a syndrome differentiation and health preservation approach based on their symptoms to nourish and protect their liver. Healthy individuals do not need to take 'liver protection' drugs for the purpose of 'preventing' liver damage. ”Wang Qi, chief physician of Beijing Ditan Hospital affiliated with Capital Medical University, emphasized that no matter what type of liver protection drugs are used, they cannot completely offset the damage caused by pathogenic factors to the liver. Improving lifestyle habits such as staying up late and avoiding pathogenic factors such as alcohol consumption as much as possible are the most effective measures to protect liver health. Li Shuqiang, a researcher at Peking University Third Hospital, reminds outdoor workers such as couriers to avoid prolonged exposure in the scorching summer to prevent heatstroke. High temperature and heat working environment, as well as factors such as human heat dissipation dysfunction, can all lead to heatstroke. If there are symptoms of heatstroke such as headache, dizziness, thirst, and excessive sweating, Li Shuqiang suggests that one must promptly go to a cool and ventilated place to rest quietly, replenish water and salt. On the basis of threatened heatstroke, if symptoms such as facial flushing, excessive sweating, and accelerated pulse appear, it is necessary to quickly use physical cooling methods such as ice packs and timely fluid replacement. Most people can recover within a few hours. If the symptoms do not improve, it is necessary to promptly seek medical treatment to avoid developing into severe heatstroke and endangering life.
