Is cold weather harmful to the body?

Cold weather is very harmful to the human body, generally speaking, the most susceptible to colds, colds and chilblains. The focus is on rheumatism, arthritis, and nephritis. Therefore, in colder areas and climates, you must pay attention to keeping warm. Especially the warmth of the feet.

The body temperature of the normal human body fluctuates between 36 and 37, and if the body dissipates a large amount of heat in a cold environment, if it is not properly protected, it will lead to a decrease in local or systemic temperature, a decrease in working capacity, and even cold injury.

Excessive cold or heat can have an impact on physical health, especially for young children and the elderly with poor physical fitness, and cold weather can be more harmful.

We humans are homeothermic animals, and we have a high degree of acceptance of the outdoor temperature in line with our body temperature, and if it is too cold or too hot, it will make people uncomfortable, which is not only reflected in the fear of heat or cold, but also in the fact that it is easy to cause dysfunction of the immune system and be easily infected with various diseases.

Cold weather makes people less resistant, easy to contract upper respiratory diseases such as colds and pharyngitis, and also greatly increases the probability of cardiovascular diseases and cerebrovascular diseases.

Therefore, it is very important to pay attention to cold protection and warmth in autumn and winter, and at the same time, it is also necessary to regulate diet, rest and exercise to enhance one's own resistance.

There is a saying that the three standards of a perfect life are health, freedom and wealth, so health is the first place, which shows that the health of the body is very important for us. What are the hazards of cold in the following?

Cool or coldAny food that is suitable for hot constitutions and illnesses is a cold or cold food. Eating too much of these foods not only cannot improve people's physical fitness, but on the contrary, they will have adverse long-term effects on people's health and cause harm to the body.

1. Damage to spleen and stomach function.

There is a saying in traditional Chinese medicine, "If you have stomach qi, you will live, and if you don't have stomach qi, you will die". Cold food hurts the spleen and stomach the most, and from traditional Chinese medicine, it is called insufficient spleen yang. In traditional Chinese medicine, the spleen and stomach are subtle in the transport of water and valleys, and if the spleen and yang are insufficient, it will affect the transport of food, resulting in a deficiency of qi and blood.

The decline of spleen and stomach function will lead to nutritional deficiency in the long term, which will lead to chronic malnutrition, which in turn will lead to other diseases, such as decreased immunity, emaciation, fatigue, etc.

From the perspective of modern medicine, eating too much cold food will cause the gastric mucosa to constrict, which will affect the secretion of digestive juices such as pepsin and gastric acid, and even lead to various gastrointestinal diseases, such as stomach cold and diarrhea.

2. Damage to kidney function.

It is said that there are many people with kidney deficiency now, of course, there are many factors here, such as fatigue, staying up late, medication, etc. And cold food is the most hurtful for yang energy. Traditional Chinese medicine says that the kidneys can only be replenished, not diarrhea.

And what is the supplement, that is, warm food is the most appropriate. Why do drugs hurt the kidneys, from the perspective of traditional Chinese medicine, many drugs are cold properties, such as antibiotics, antipyretic analgesics, etc. Therefore, people with chronic diseases or poor immunity for many years, regular medication, can lead to impaired kidney function.

And the cold food we usually eat is even worse for the kidneys. The so-called yang deficiency constitution, that is, insufficient yang energy, insufficient calories, and overeating cold food, is a great sin!

3. Damage to cardiovascular function.

There is a saying in traditional Chinese medicine, "When blood is cold, it will coagulate, and when it is warm, it will do". Warm food can promote blood circulation, which is often referred to in traditional Chinese medicine as blood circulation and blood stasis. For some people with cardiovascular and cerebrovascular diseases, it will form blood clots, block blood vessels, and induce cardiovascular diseases such as myocardial infarction and cerebral infarction.

Therefore, cold food is a contraindication for cardiovascular disease.

Fourth, it leads to a decrease in immunity.

Nowadays, the incidence of cancer is very high, although environmental factors, social factors, dietary factors, etc. are the main reasons, but it is undeniable that the decline of immunity is also a common disease of modern people. There are many factors that affect immunity, and yang deficiency constitution and hypothermia will also affect people's immune function. This study showed that for every degree drop in body temperature, immunity decreased by 30%.

For every degree of increase in body temperature compared to normal body temperature, immunity will increase by 5-6 times. Therefore, eating too much cold food, which leads to a drop in body temperature, is also one of the factors that lead to a decrease in immunity.
