The arrival of the beautiful summer season for someone is a real torment.
Heat intolerance results from the great difficulties for the organism to adjust its internal balances to adapt to the temperature. In these cases, the sweating is intense, the face becomes redder and in some cases even the clothes take on a different color. Why do some suffer more from heat?
Body temperature
The human body temperature of 36.5°-37° is indicated as normal, with a certain degree of variability at an individual level. A healthy organism implements the complex processes of thermoregulation of the body, which depend on the hypothalamus. Thanks to these biological mechanisms, the internal temperature is maintained at a constant level of the regulatory regime.
Body temperature is not always the same: it usually seems to be lower between 4 and 5 degrees in the morning, then rises in the late afternoon between 5 and 6 o'clock.
What happens to the body in hot weather?
When we are in a cold environment, the process of thermolysis increases and there is a loss of heat balanced by a vasoconstriction of the skin. Heat affects the dilation of blood vessels, which can cause the typical hot flush.
When do you suffer from heat the most?
The process of production, maintenance and dissipation of heat by the body appears to be related to hormonal activity. During ovulation, the body temperature rises, you know? Secreted progesterone affects about 0.5 ° C in relation to the basic values. Excessive sweating problems can in some cases be related to the activity of hormones.
When we are moving, for example if we are late or because we are playing sports, the body produces more heat. This also happens when we eat: digestion requires energy. Physical activity, food, the rhythm of awakening from sleep, as well as thyroid dysfunctions, show to have an important role in the fluctuations related to the body temperature.
Are you experiencing a moment of intense stress?
Attention, in this case there is an increase in the production of adrenaline and noradrenaline in the body: metabolism is stimulated, body heat increases.
The sudden increase in body temperature, known as heat stroke, can appear with signs of loss of appetite, headache, dehydration, the presence of convulsive episodes.
The heat waves typical of the summer period are more surmountable when we find ourselves in a hot dry climate. In fact, the human body generally tolerates even high temperatures, provided that there is a humidity level of about 30%: the higher the humidity, the more frequent the cases of the disease.
The elderly and newborns may have more difficulty in compensating mechanisms, but those suffering from hypertension, cardiovascular disease, chronic kidney failure, neurological disease and chronic respiratory disease are also at risk.
Those who work outside or play an intense sport can risk dehydration, fluid supply is essential. In the case of an emergency treatment, it is necessary to move the person to a cold environment and to help him drink something, replenishing fluids thanks to drinks rich in mineral salts and sugars./ TAR
