The summer has passed, which means it is time to turn on heating. Regardless of the place-in the office or at home-it becomes the cause of constant disputes: someone will always be cold, and someone, on the contrary, is unbearably stuffy. A recent study found that a third of the families are wrapped due to the thermostat, and 40% of women secretly twist the heater at home. Personal preferences may differ, but most often the parties in such disputes are divided by the floor: women most often freeze, and men insist that the room is too hot. And it's not about nit-picking and stereotypes: representatives of the two sexes really perceive the temperature in their own way. Paradoxically, the male and female body in terms of thermoregulation work a little differently-these are biological mechanisms.
We know about what our temperature should be due to the work of the German doctor Karl Vyunderlich . It was he who introduced the patient’s temperature schedule to practice and proved that heat is a symptom, not an independent disease. Having studied the data of 25 thousand people, the university found that the normal temperature of the human body is about 37 ° C; He also noticed that "adult women can be a little warmer than men of a similar age." This was later confirmed by other researchers.
The human body is perfectly able to maintain the operating temperature in the range he needed even contrary to external temperature differences. When hot, blood vessels in the skin expand to increase heat transfer; In parallel, we sweat. When it is cold, the vessels, on the contrary, are compressed so that less heat passes through the skin; At the same time, muscles can sharply decline to produce additional heat, and we feel that we are trembling from the cold.
In fact, the temperature of our body changes during the day and depends on the biological rhythms of the body. For example , most of us by evening (16-18 hours) by 0.5–1 ° C warmer than early morning (6 hours). In women, the temperature can also vary due to pregnancy or taking hormonal contraceptives-in both cases it increases by the same 0.5–1 ° C.
