Jiangsu has started the continuous rainy mode. What effect does rainy day have on human body?

According to the weather forecast issued by Jiangsu Meteorological Observatory, the highest temperature today is 15 ~ 16℃ along the Yangtze River and southern Jiangsu, and 12 ~ 13℃ in other areas, which is slightly lower than yesterday, so we can't take off our warm clothes. Umbrellas, raincoats and rain boots should also be prepared these two days. When the temperature drops, the rain will follow. Today, the province is cloudy to cloudy, with light rain in most areas, and the northerly wind in the province is 3-4. This round of precipitation will last until 654381October 23rd. 654381October 22 Huaibei turned cloudy to light rain, and other areas were cloudy with light rain to moderate rain. 65438+1On October 23rd, the southeast of our province was cloudy with light rain to moderate rain, while other areas were cloudy with light rain. With the arrival of precipitation, the temperature has also dropped, so pay attention to cold and warmth. ? Speaking of rainy days, it not only has a negative impact on our human life, but also has an impact on our human body to a greater or lesser extent.

1, the temperature difference is large in rainy days. The change of temperature has the greatest influence on human body. The temperature in rainy days is more than 2℃ lower than usual. The sudden drop in temperature is easy to catch a cold, especially for the elderly and children, and their own resistance is very weak. Moreover, the air humidity is also high in rainy days, which is easy to induce the recurrence of various old diseases such as rheumatism and neuralgia. In addition, it can also cause low back strain, sprain, fracture, surgical incision and other parts and adjacent joints often have pain.

2, induce respiratory diseases, in cold and rainy weather, cold, moisture and various poisonous bacteria are more likely to sneak into the human body, causing respiratory diseases. Everyone closes the doors and windows to keep warm, which leads to poor indoor air circulation, and bacteria and dust suspended in the air are not easy to disperse, which is easy to induce respiratory diseases such as upper respiratory tract infection, bronchitis, pneumonia and asthma, ranging from nasal congestion and sneezing to difficulty breathing and wheezing. Once the disease occurs, it is often difficult to cure, and emphysema or cor pulmonale will form over time.

3. Cardiovascular and cerebrovascular diseases are prone to occur in rainy days; Because the air pressure is low at this time, it is easy to accelerate blood vessel contraction and easily cause chronic cardiovascular and cerebrovascular diseases such as hypertension and heart disease.

4. In rainy, muggy and humid environment, food is easy to go moldy and deteriorate. After eating, it can directly or indirectly cause poisoning, with symptoms such as vomiting and diarrhea. Eating food contaminated with aflatoxin can also lead to liver cancer and stomach cancer.

5, rainy days will indirectly affect people's emotions, rainy days, sunshine time is reduced, affecting human metabolism, and the pineal gland in the human body secretes more pineal hormones. At the same time, the concentrations of thyroxine and epinephrine decreased relatively. Thyroxine and epinephrine are hormones that stimulate cells to work. Are relatively reduced, cells will? Lazy? , become extremely inactive, people will also appear listless and reduce work efficiency.
