Harm of sultry room to human body

A stuffy room is harmful to human body. In our life, we sleep in the bedroom every day, but now it is summer, and the room will be stuffy after a long time, and it will be uncomfortable when we enter the room. The following is the harm of stuffy room to human body.

Hazards of sultry room to human body 1 Too hot and indoor temperature is too high, which is harmful to human body. In the cold winter, overheating at home will not only cause colds, but also bring other diseases. In winter, the air is dry, and indoor heating evaporates the scarce water in the air. People are prone to "fever", that is, due to lack of water in the body, symptoms such as colds, coughs, chapped lips and oral ulcers often occur, endangering the functions of the respiratory system, cardiovascular system and urinary system. This is also a common endemic disease in northern China.

For the elderly and patients with a history of cardiovascular diseases, the indoor temperature is too high and the water evaporates too fast, which can lead to the increase of blood viscosity and cause cardiovascular diseases such as blood pressure fluctuation and angina pectoris. Excessive temperature difference between indoor and outdoor can also cause coronary heart disease. Seasonal indoor temperature is generally between 18℃ and 22℃, and human body feels most comfortable. In addition, don't just pursue the temperature, but also coordinate the humidity. For example, 18℃ to 25℃, and the humidity at home should be between 30% and 80%.

What effect does damp heat in the house have on the body?

According to disease analysis, damp-heat can cause loss of appetite and digestive function, poor spirit and decreased human resistance. The reason of damp heat is that the room is not ventilated for a long time, and harmful gases such as carbon dioxide, dust, dander and smoke in the air increase, which is not easy to be discharged. So let the human body feel sultry, irritable and depressed. So the living environment should be suitable for temperature and humidity.

Does room temperature affect body temperature?

Indoor overheating will affect the body temperature. If the indoor temperature is too high, the heat dissipation function of the human body will be affected to some extent, and the heat dissipation of the body will decrease, but some body temperatures will increase. At this time, it is necessary to keep indoor ventilation, and it is more appropriate to keep the room temperature above 20 degrees, which has little effect on body temperature.

Under normal circumstances, if the outside temperature is normal, if the body temperature is measured under the armpit, the normal body temperature is between 36 and 37 degrees, and a fever is considered if it exceeds 37 degrees. If the body temperature is measured in the mouth, it is between 36 to 3 degrees and 37 to 2 degrees, and it can be regarded as a fever if it exceeds 37 to 2 degrees.

If the temperature is measured in the anus, the temperature is between 36 to 5 degrees and 37 to 7 degrees, and it is considered as a fever if it exceeds 37 to 7 degrees.

Hazards of sultry room to human body 2 Warm and humid environment is conducive to the growth and reproduction of mold, especially the mold on human skin will "revive" and spread in toes and other parts, causing beriberi. If athlete's foot is not treated in time, it will spread to other parts of the body and become tinea corporis, tinea cruris, tinea manus and tinea versicolor. Studies have shown that mold can also grow and reproduce in the human body, causing fungal pneumonia and other diseases. Being in a humid, stuffy and unventilated room for a long time will do the following harm to your health:

1, respiratory allergy

Allergic diseases: Inhalation of mold in sensitive person can cause respiratory allergic symptoms, ranging from stuffy nose, runny nose and sneezing, and in severe cases, it can make people have difficulty breathing and wheezing. Mold and its metabolites enter the human body through various channels, and can also cause allergic bronchitis, bronchial asthma, hay fever, dermatitis and so on. , or make the original allergic disease relapse.

2, joint pain

Due to the changeable temperature and high humidity in the air, it is easy to aggravate or worsen the condition of rheumatoid arthritis and rheumatoid arthritis. It can also lead to lumbar strain, sprain, fracture and pain in surgical incision and adjacent joints.

3. Food poisoning

In a hot and humid environment, food is easily polluted and moldy. People who eat this moldy food will directly or indirectly cause poisoning, vomiting, diarrhea and other symptoms. Studies have shown that eating food contaminated with aflatoxin can lead to liver cancer, stomach cancer and other diseases.

4. Cardiovascular and cerebrovascular diseases

Meteorological factors such as air pressure, temperature and air humidity change greatly in rainy season, which can easily lead to autonomic nervous dysfunction, vasoconstriction, blocked blood flow, increased blood pressure, increased myocardial oxygen consumption and increased heart load, thus inducing cardiovascular and cerebrovascular diseases such as myocardial infarction and stroke.

Tip 1. Adjust the indoor temperature.

The suitable indoor temperature in winter is 18-25℃. If you are a mental worker, it is the best choice to keep the temperature around 18℃ because it is conducive to thinking. The easiest way to adjust the indoor high temperature is to open the window for ventilation. If the room temperature is too low, you can use heating tools such as electric heaters.

Tip 2. Control indoor humidity

The suitable humidity is 30-80%, and 40-60% is the most comfortable. To increase the humidity, you can use a humidifier scientifically, place a basin, and put wet towels on the heater. Need to be reminded that the humidifier must be cleaned frequently to prevent it from becoming the root of bacteria and viruses.

In addition, buying a thermometer is very helpful to adjust the temperature and humidity of a heated room ~

Tip 3. The heating is completely clean and kept continuously, and the room is often ventilated.

Tip 4: Drink plenty of water.

If you have heart failure and other conditions that are not suitable for drinking more water, you need to consult a professional doctor before deciding how to replenish water more scientifically.

Harm of muggy room to human body. The influence of high temperature and sultry weather on human health is mainly heatstroke and death caused by cardiovascular and cerebrovascular diseases.

Under the action of excessive ambient temperature, the thermoregulation mechanism temporarily fails, leading to heat accumulation in the body and heatstroke.

According to the symptoms and degree of heatstroke, it can be divided into:

Heat collapse is the mildest and most common manifestation of heatstroke;

Thermal radiation refers to long-term work in a high temperature environment, which leads to vasodilation and congestion of the lower limbs, leading to fainting;

Heatstroke is caused by long-term exposure, which leads to perspiration dysfunction.

For patients with hypertension, cardiovascular and cerebrovascular diseases, in the environment of high temperature, humidity, no wind and low pressure, perspiration is inhibited, the stored heat in the body is increasing, and the myocardial oxygen consumption is increasing, which makes the cardiovascular system in a state of tension. The sweltering heat can also lead to vasodilation and increased blood viscosity, which is prone to symptoms such as cerebral hemorrhage, cerebral infarction and myocardial infarction, and may lead to death in severe cases.

According to the investigation of cardiovascular and cerebrovascular diseases in Beijing, it is found that hot and humid weather is a dangerous weather that leads to ischemic stroke.

It's sultry in summer, and it's also prone to colds (Xia Han), diarrhea, skin allergies and other diseases. The reason is that in the high temperature environment, human metabolism is vigorous, energy consumption is large, and sultry heat often makes people lack sleep and lose appetite, which leads to the decline of human immunity. At this time, if you don't control the use of air conditioners or electric fans to relieve summer heat, the human body will be in a low temperature environment for a long time, and its adaptability and resistance will decrease, and germs and viruses will take advantage of it and easily cause upper respiratory tract infections (colds).

In addition, in the high temperature and high humidity environment, bacteria, viruses and other microorganisms multiply in large quantities, and food is easy to deteriorate, which will cause indigestion, acute gastroenteritis, dysentery, diarrhea and other diseases after eating; When people come home from the outdoor high temperature environment, they are used to turning on the air conditioner or directly blowing it with an electric fan and eating some iced food. This cold and heat will take effect immediately, and diarrhea will begin immediately. The sultry weather makes people sweat poorly, and it is also easy to cause skin allergies, mainly papular urticaria, eczema, contact dermatitis and so on.
