How does climate affect humans?

Almost invariably, a person is subject to the influence of the climate of the area where he lives. Over the years, the already established weather pattern affects the health and performance of a person. Even if a person is already accustomed to the local climate, his body still reacts to changes in the seasons, and some people who are affected by climate variability even with small fluctuations may perceive it rather painfully. And in this case, it becomes obvious that a person is dependent on climate, which, under the influence of certain factors, may be more active or may be in a depressed state.

Climate should include not only changes in meteorological factors, but also solar and terrestrial radiation, atmospheric electricity, terrain landscape and magnetic fields, that is, the whole complex of climate factors that can directly affect the human body.


The impact of climate on human health has long been proven. With high air temperature, peripheral vessels dilate, blood pressure decreases, the body redistributes blood and metabolism in the body.At low temperatures, peripheral vessels are reduced, blood pressure rises, the pulse quickens, and metabolism and blood flow increase.

  • With fluctuations in temperature, changes occur in the human nervous system. So, at high temperature, there is a decrease in excitability, and at low - excitability increases. The reaction of the other systems of the body directly depends on the reactions of the nervous and circulatory systems, as well as metabolism. But the scheme of reactions can vary depending on the degree, duration and rate of change in ambient temperature, and the individuality of each person and the level of acclimatization to certain conditions play a big role. Testing all the processes of climate variability, the body produces thermoregulatory reflexes that provide resistance to various temperature fluctuations.
  • Humidity, in the first place, affects the heat transfer, which affects the thermoregulatory functions of the body. Air masses can cool a person’s body if they are cold, and if they are hot, they will therefore heat the body.When the wind influences, the thermoreceptors of the skin are primarily irritated, and the irritation can be pleasant, or cause negative sensations. At an altitude after 300-800 meters above sea level, to replace the barometric pressure, a person can react with hyperventilation of the lungs, as well as changes in the circulatory system. When the height increases, all these reactions become even more pronounced, the content of red blood cells and hemoglobin increases in the blood. When a person is at a height with a pressure of 500-600 mm Hg. st. in combination with low temperature and solar radiation, it increases the metabolic rate, which can beneficially affect certain pathological processes. Therefore, an abrupt change of climate and barometric pressure is not recommended to sick people.
  • Seasonal fluctuations, as a rule, cause a person to change the activity of physiological functions, with changes in the reactions of the nervous system, the activity of the endocrine glands, metabolic processes and heat transfer. If a person is healthy, then on such changes as, for example, a change in the seasons, he practically does not react due to his fitness for this organism.On the contrary, sick people can perceive it very painfully, with deterioration of the general condition and exacerbation of diseases.

Doctors can compare one or another influence of climate on human life, depending on its type. Also, different types of climate can have a variety of physiological effects on humans.


  • The sea climate, with fresh, moist, saturated sea salt air, combined with blue distances and continuously running waves, in almost any case, has a beneficial effect on the nervous system. Beautiful shores, especially of the southern seas or oceans, where solar radiation is reflected, and there are no sharp fluctuations in temperature, contribute to enhancing the normal balance between the processes of excitation and inhibition in the nervous system, as well as normalize the various physiological processes of the body if it contains pathological changes. As therapeutic measures, these climatic conditions have an effect on trophic and metabolic processes, which helps to eliminate the disease state, and in the body of a healthy person they can enhance adaptive physiological reactions.
  • The mountain climate, with low pressure, high altitude, a sharp change in the temperature of day and night, and fresh air can prove that the influence of climate on human activity can become stimulating. In such conditions, the excitability of the nervous system increases, the activation of psychological processes, and, consequently, productivity can increase. No wonder so many creative people get inspiration in the mountain settlements, with beautiful nature and fresh air.
  • The climate of the desert, is a dry and hot air, hot dust, and makes the adaptation processes to work in an enhanced mode, which is not a favorable factor. Dry and hot weather causes a person to have a lot of fluids, up to 10 liters per day.
  • The climate of the north, with the monotony of the plains, winter cold and cold, is considered a good tempering agent. Metabolism increases due to increased heat generation. Stabilize all body systems.

Based on these data, you can imagine how the climate affects people, and what consequences it can cause to our body.
