The arrival of the beautiful summer season for someone is a real torment. Heat intolerance results among the great difficulties that the body regulates its internal equilibria to fit the temperature.
In these cases, sweating is intense, the face becomes red and in some cases the clothes take on another color. Why do some people suffer more heat?
Body temperature
According to the convention, the human body temperature of 36.5 ° -37 ° is indicated as "normal", with a certain degree of variability at an individual level. A healthy body implements complex thermoregulatory processes that depend on the hypothalamus. Thanks to these biological mechanisms, the internal temperature is maintained at a constant regulatory level.
Body temperature is not always the same: it usually appears to be lower between 4 and 5 degrees in the morning, then increases at the end of the afternoon between 5 and 6 o'clock.
What happens to the body in hot weather?
When we are in a cold environment, the thermolysis process increases and there is a loss of heat balanced by a skin vasoconstriction. Heat affects the dilation of the blood vessels, which may cause the typical heat outbreak.
When are you suffering from the heat?
The process of production, maintenance and distribution of heat from the body seems to be related to hormonal activity. During ovulation increases body temperature, do you know? The secreted progesterone affects about 0.5 ° C with respect to the basic values. Excessive sweating problems may in some cases be related to hormone activity.
When we are in motion, for example, if we are late or because we are doing sports, the body produces more heat. This also happens when we eat: digestion requires energy. Physical activity, nutrition, sleepwalking, and thyroid dysfunction show a significant role in fluctuations associated with body temperature.
Are you experiencing a moment of intense stress? Care, in this case in the body there is an increase in the production of adrenaline and norepinephrine: metabolism is stimulated, the body heat increases.
Hyperthermia, symptoms
Immediate increase in body temperature, known as heat stroke, may appear with signs of loss of appetite, headache, dehydration, and the presence of convulsive episodes.
Typical summer heat waves are more overcome when we find ourselves in a hot, dry climate. In fact, the human body generally tolerates high temperatures, provided it has a humidity of about 30%: the higher the humidity, the more frequent the cases are.
Elderly and newborns may have more difficulty in compensating the mechanisms, but those who suffer from hypertension, cardiovascular disease, chronic kidney failure, neurological diseases and chronic respiratory diseases are also at risk.
Those who work outdoors or play an intense sport can endanger dehydration, supplying juices is essential. In the case of an emergency treatment it is necessary to move the person in a cold environment and to help him drink something, filling the liquids thanks to the drinks rich in mineral salts and sugars. These are all fast and efficient solutions.
