The influence of complex and changeable climate on our life.

(1) Climate has a significant impact on people's health and mood: we know that climate has an impact on some diseases, such as arthritis and heart disease. Climate can also make people feel irritable. Therefore, people should master these laws, give full play to their subjective initiative, pay attention to restraint when they are upset, and pay attention to protection for sick people.

(2) the influence of humidity on people: rainy days can make people feel depressed. Of course, some of this bad mood is due to social factors. However, research shows that in the days with heavy humidity, more people will get depression; The low air pressure before cloudy days and rain will make school-age children fidget.

(3) the influence of sunlight on people: sunlight is really good for mood, especially in winter. On sunny days, people will be more willing to help others and abide by social order. But summer heat and sunny days are exceptions.

(4) What is the relationship between dry hot air and bad mood? In many countries, such as the United States, Switzerland and Israel, this dry hot air will increase mental disorders. People will be inefficient, slow-witted and easily angry. We think this is because this wind reduces negative ions in the air, which are good for people. They can improve people's brain function and improve their mood. Positrons have the opposite effect. Some surveys show that people will be extremely active and excited before a rainstorm. We think this is related to the change of charged particles in the air. Lightning can increase negative ions in the atmosphere, which makes people happy.

(5) the influence of atmospheric pressure: the change of atmospheric pressure will cause many health problems. When the atmospheric pressure changes, the cavity in the human body expands, such as: the decrease of atmospheric pressure will cause sinus problems, resulting in sinusitis and sinus expansion; The increase of air pressure has great influence on human joints; A drop in air pressure can also make people restless.

(6) Influence of extremely cold and hot climate on heart patients: Extreme temperature, especially very cold weather, will overload people's cardiovascular system. More people will die of heart disease in winter than in other seasons. Because when the temperature is very low, blood flows into the body from the skin, and the heart should beat the blood hard to keep the body warm. Therefore, some strenuous activities in the cold climate will increase the burden on the heart. Another death peak of heart patients is in summer. Summer heat makes the heart beat worse, makes people sweat more, and raises blood pressure. Extremely cold and hot climate will overload people's immune system, thus weakening people's resistance. Hot weather can make people extremely susceptible to infectious diseases such as malaria. Colds and respiratory infections are common in winter, because low temperature weakens the body's resistance.

(7) Who is particularly sensitive to climate? A few people are particularly sensitive to climate, but they are also sensitive to environmental problems such as noise pollution. Comparatively speaking, the elderly are more sensitive to the climate than the young, because the cardiovascular system of the elderly is weak. The weight is the same. Fat people feel bad in hot weather, but thin people feel bad in cold weather. In the experiment, men and women have almost the same reaction to climate.

(8) Effects of air conditioners and dryers: It is good that these devices create an artificial indoor climate so that people can avoid the effects of extremely cold, extremely hot and extremely humid climate. However, the air conditioner absorbs negative ions in the air, which has adverse effects on brain function and mood. Air conditioners produce a lot of cations, and staying in this air for eight hours will cause headaches. In the past, we thought that indoor headaches were caused by carbon monoxide, but now studies have proved that the increase of cations is also one of the reasons.

In the experiment, negative ions produced by ion generator can improve the mood of office workers. Negative ion air is good for people's mood. One of the reasons why people like to travel to mountainous areas is that there are a lot of negative ions in the air there.

(9) the influence of climate on sleep: people who are afraid of heat can hardly fall asleep in summer. Sleep research experiments show that when the air pressure is higher or lower than normal, people feel sleepy, and the reason remains to be studied.

(1) What climate is ideal for physical and mental health? The temperature is around 21℃, and it is best to have some breeze and not too strong sunshine.

The human body is quasi-constant. In order to keep the body temperature constant, it is necessary to continuously discharge the heat generated by metabolism to the outside world, so that the skin temperature is higher than the outside temperature. When the temperature is close to the skin temperature, the heat dissipation will not be smooth, which will cause discomfort. At this time, the human body will increase sweat and release heat in the form of evaporative heat dissipation. According to the research, when the general temperature is 3-32℃ and the relative humidity is 85%, or when the temperature is 38℃ and the relative humidity is 5%, or when the temperature is 4℃ and the relative humidity is about 3%, people's body temperature adjustment ability will be difficult, resulting in heatstroke.

In the summer of p>1997, the seasonal average temperature in most areas north of the Yangtze River was 1-2℃ higher, and the average temperature in most parts of North China, Northeast China, Northwest China and western Xinjiang from mid-June to late August exceeded the highest value in the same period since 1949.

According to incomplete statistics of relevant units, just before July 1th, there were more than 18 traffic policemen suffering from heatstroke in Beijing. During the high temperature period, the number of patients in major hospitals increased sharply. The number of emergency patients in Friendship Hospital increased by 1/3 compared with the same period of last year, and the number of seriously ill patients increased by 2-3 times. Children suffer from colds, fevers, colds and intestinal diseases, and the maximum number of outpatient visits in children's hospitals is more than 4,5. The hot weather makes many people flock to swimming places and natural waters to cool off the heat. According to statistics in early August, more than 5 people died of drowning in Beijing.

The occurrence and development of human diseases are often related to seasonal climate change. The weather in spring is characterized by variability, and "cold spring" and sandstorm weather often occur. This period is the high incidence season of respiratory infectious diseases, and diseases such as colds, rubella, chickenpox, measles, meningitis and scarlet fever are often prevalent, and the incidence of myocardial infarction in middle-aged and elderly people is also very high. Japanese encephalitis mostly occurs in summer and autumn; Gastrointestinal diseases such as cholera and dysentery are more common in summer.

According to the research in Shanghai in recent years, there is a certain relationship between human mortality and seasonal changes. After late autumn, the death toll increased sharply; Winter is the peak of death toll, and the coldest February is twice as many as May and June. The daily average temperature is between 15-25℃, and the number of deaths decreases, but under the attack of heat wave in summer, especially when the daily maximum temperature reaches above 35℃, the number of deaths suddenly increases. These research results show that seasonal climate change and severe weather change do have great influence on human health.

Modern scientific research has proved that people can use favorable weather and climate conditions to treat diseases, which is often called climate therapy. Such as mountain climate convalescence, seaside climate convalescence, desert climate convalescence, forest climate convalescence, etc. Patients can choose a health resort according to the symptoms.

We know that weather and climate are closely related to human health, so it is necessary to master the changes of weather and climate. First, increase clothes in time to adjust the adaptability of the human body to weather changes; The second patient can take medicine in advance to prevent problems before they happen; Third, we should avoid other diseases caused by influenza. In short, strengthening exercise, improving physical fitness and avoiding its adverse effects on the human body are important ways for everyone to keep healthy.

Climate change has a direct or indirect impact on human health. The weather caused by climate change, such as heat waves, floods, storms, abnormal climate events and sea level rise, directly affect human health and life. At the same time, climate change will also affect the supply of fresh water resources, aggravate air pollution and have an indirect impact on health. More importantly, climate change can cause corresponding changes in ecology and environment, leading to the imbalance of global ecosystem functions. With the global warming, malaria, dengue fever and other diseases spread by insects will probably affect 4% ~ 5% of the world population, which will greatly threaten human health and daily life. In areas with high temperature and high humidity, climate warming may cause mosquitoes and flies to breed and increase the incidence of cholera, malaria and yellow fever. At the same time, due to systematic changes in temperature and precipitation areas, the distribution of diseases spread by disease vectors and viral diseases may be fundamentally changed and moved to higher latitudes, resulting in the expansion of the epidemic range of biological diseases such as malaria, schistosomiasis, trypanosomiasis, yellow fever, plague and cholera, and more people are at risk.
