The harm of long-term sultry heat to health

The disadvantages of long-term sultry heat to the body. It's annoying when the weather is sultry. Environmental temperature is closely related to human health. Generally speaking, the best environmental temperature that the human body can adapt to is between 20 degrees Celsius and 28 degrees Celsius. When the weather temperature rises, the human body will produce a series of physiological function changes. The following are the disadvantages caused by long-term sultry weather.

The harm of long-term sultry heat to the body 1 High temperature directly causes diseases.

Under the condition of high temperature, diseases directly caused by high temperature include heatstroke and mental and neurological disorders.

Heatstroke is an acute heatstroke disease characterized by the disorder of central nervous system and cardiovascular system caused by heat balance and water and salt metabolism in high temperature environment.

Mental nerve disorder, also known as thermal fatigue, refers to the adverse effects of high temperature environment on mood, work ability and technical efficiency.

High temperature-induced diseases

In the high temperature environment, because the human body is in a state of thermal stress, sympathetic nerves are excited, sweating a lot, blood viscosity increases, the cardiovascular system is in a state of high load operation, and the function of the digestive system is weakened, thus causing the aggravation of the original diseases, such as sudden changes in blood pressure in the early and late heating, which can induce heart disease, congestion, coronary heart disease and so on. The increase of blood viscosity can cause thrombosis, which can lead to stroke; The weakness of digestive system leads to poor nutritional status of human body, which further aggravates the original organic diseases.

Common high temperature diseases

heat and cold

In summer, when the temperature is high, human metabolism is vigorous and energy consumption is high. However, heat often makes people lack sleep, lose appetite, and human immunity and resistance begin to decline. In addition, if they are too greedy for cold, such as blowing fans or air conditioners directly, germs and viruses will take advantage of it, thus causing colds and colds.

suffer sunstroke

In the hot summer, the human body sweats more, while the old people have less water than the young people, and their physiological reaction is slower, so they are easy to dehydrate in summer, which will lead to thick blood. This is undoubtedly "adding fuel to the fire" for the old people suffering from hypertension, hyperlipidemia or cardiovascular and cerebrovascular diseases, and the blood transfusion in the brain is blocked and slowed down, and the probability of intermediate points increases.

diarrhea

Diarrhea has much to do with improper diet. High temperature and humidity in summer will promote the reproduction and growth of bacteria, and food will rot easily. If you don't pay attention to your diet, diarrhea will occur, especially for children or infants.

psychosis

Due to the influence of high temperature, about 16% people will have emotional and behavioral abnormalities, especially middle-aged and elderly people. This condition is called "summer affective disorder". The occurrence of this situation is closely related to temperature, sweating, sleep time and insufficient diet. When the ambient temperature exceeds 30℃, the sunshine time exceeds 12 hours, and it is moderately higher than 80%, the influence of meteorological factors on the emotional regulation center of human hypothalamus is obviously enhanced, and the occurrence of emotional disorders is obviously increased. In addition, excessive sweating and electrolyte metabolism disorder affect brain nerve activity, leading to abnormal mood and behavior.

High temperature death

High temperature has many effects on human health, some directly lead to diseases, some indirectly affect the original diseases, or affect people's emotions and nervous system, and the most serious consequence is death.

As a meteorological factor, high temperature itself can directly lead to severe heatstroke death, and can also be used as an inducing factor to aggravate the illness of some patients with serious organic diseases and die; In addition, high temperature will weaken people's nervous function, leading to accidents and deaths, and even people's behavioral adaptation activities at high temperature will lead to behavioral changes and dangerous behavioral factors that lead to death.

Which diseases easily lead to death?

As a meteorological factor, high temperature can directly affect the human body and lead to heatstroke. Although the human body has strong adjustment ability and can adapt to the general high-temperature environment, long-term exposure to high temperature or excessive thermal radiation will cause high-temperature injuries, such as heat exhaustion, heatstroke and thermal spasm, among which the death rate of severe heatstroke is very high.

The high temperature in summer, moderately high, reduces the cooling effect of sweating, coupled with long-term heavy physical labor, increases the heat generated by muscles; Old people, obese people and alcoholics are sensitive to high temperature injury, which increases the risk of high temperature injury.

The disadvantages of long-term sultry heat to the body II. The sultry office leads to sub-health.

People who work in the house for a day are prone to rising virtual fire, often dizzy, and their cheekbones are hot and red. These are all phenomena of hypoxia, and the harm to health caused by working in such an environment for a long time is self-evident. Some people think that the high indoor temperature is too scary to bake, and it is especially easy to catch a cold when going out; Some women feel that low humidity has damaged their skin; More people believe that polluted air makes people who are already "sub-healthy" more prone to respiratory diseases such as pharyngitis and tracheitis.

So how to effectively deal with the sultry office?

Appropriate clothes+drinking water+moisturizing

In addition to using some tips to reduce air pollution and adjust humidity, it is also necessary to adjust the inside and outside of the body to cope with the stuffy office:

The first thing is to dress properly to reduce the impact of indoor and outdoor temperature difference on the body, so as to reduce the chance of catching a cold and other respiratory diseases, and try to wear thin clothes in a hot office.

Many white-collar workers are highly nervous when they start working, and rarely leave themselves time to drink water and go to the toilet, which is not conducive to reducing the deposition of waste in the body through water metabolism. Working at a desk for a long time will also increase the load on the musculoskeletal structure of the neck and back, leading to cervical spondylosis and musculoskeletal injury of the back. Although physical exertion is not great, I still feel backache and fatigue after a day's work.

If we can scientifically drink a small amount of water in stages, it will not only make the water added to the body easy to absorb, but also relieve the fatigue of some parts of the body.

The disadvantages of long-term sultry heat to the body 3 sultry heat refers to the weather with small wind, poor breath and high temperature. The sultry weather, high temperature and low air pressure make people feel sultry and irritable.

The effects of hot and muggy weather on human health are 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 degrees, heatstroke can be divided into: heatstroke, which is the mildest manifestation of heatstroke.

It is also the most common; 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 and cardiovascular and cerebrovascular diseases, sweating is inhibited in high temperature, high humidity, windless and low pressure environment.

With the increase of heat storage in the body and the increase of myocardial oxygen consumption, the cardiovascular system is 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 the air conditioner or electric fan is used to relieve the heat, the human body will be in a low temperature environment for a long time, and its adaptability and resistance will decrease.

Germs and viruses will take advantage of it and easily cause upper respiratory tract infection (cold); 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.
