What is the maximum level and the minimum temperature that the body can achieve? The human body can not handle large variations in internal temperature. At 42 C, only 5 C above normal, the proteins begin to cook and whole body panics. Already cold causes the metabolism to decrease, but is not as fatal as the heat. The thermometer abbey house vets down to 20 C needs to happen irreversible cardiac arrest. But well before these extreme abbey house vets limits the body starts to react. "With 40 C begins to call hyperthermia (overheating) and 35 C hypothermia (lack of heat)," says physiotherapist Sergio Carnation, Federal University of São Paulo (UNIFESP). To avoid abrupt variations, the body has a number of mechanisms to keep the internal temperature constant regardless of the weather. To contain the heat, the main mechanism is perspiration. The temperature decreases because abbey house vets sweat to evaporate, it removes heat from the skin, refreshing it.
In humid environments, perspiration evaporates more difficult, so we feel more elevated temperatures. To face the cold, one of the tricks the body is to shake the person, which helps produce heat internally. But it is clear that in extreme situations such mechanisms do not work. In the book Life on the Edge - The Science of Survival, the British physiologist Frances Ashcroft talks about the body's response to environmental temperature limits. According to her, the mark of -29 C, which would be bearable with proper clothing, can become fatal if coupled with a wind of 40 km / h, which would produce an equivalent wind chill to -66 C, enough to freeze the meat 30 seconds. In the heat, the survival record is 20 minutes at 127 C in dry air. Ultimately, the resilience of the human body depends on the external temperature, humidity, wind, time of exposure to the environment and to the fact the person is immersed in water. As the water cools fast, just someone to soak about 20 C to avoid the risk of dying. Fever chills the body resists more to fall than to rise in internal temperature 42 C - The body is literally close to cooking and the functioning of the organs and the entire metabolism is affected. The person may go into a coma. At this temperature, there is no guarantee that life can be saved. 40 C - Here begins hyperthermia (overheating). The loss of fluids and minerals cause dizziness, nausea and vomiting, confusion and loss of consciousness. At that point, the person may even stop sweating, a sign that is dehydrated. 38 C - In fever, the person begins to sweat a lot, feel muscle spasms and exhaustion. The pulse is weak and fainting may occur. The recommendation is to avoid the sun, throw cold water on the body and drinking cold soft drink. 36.5 to 37.5 C - Normal body temperature 35 C - Here begins abbey house vets hypothermia or excessive heat loss. One feels chills, tiredness, apathy and lose a bit of coordination. The reasoning is slow and the judgment is affected - the person can not cooperate with anyone who tries to help her 30 C - At this level, the blood flow to the brain decreases, abbey house vets causing confusion and reasoning problems. The heart rate can reach the rate of only one or two beats per minute, in which the person appears dead 20 C - As the body temperature drops, your metabolism slows down more and more, until the heart stops and the brain activity ceases completely.

Why fever increases at dusk? There is no evidence that this actually occurs. It turns out that, with or without fever, body temperature abbey house vets fluctuates naturally, and in the late afternoon, it is customary to see an increase in this temperature - but science has not yet discovered why. "One hypothesis is that muscle abbey house vets contractions performed during the day to keep our body warmer, reaching the highest temperature at dusk. Already the state of muscle relaxation we wake in the morning would have the opposite effect," says the general practitioner Zyun Masuda, of São Paulo. If the person has a fever, another abbey house vets factor may help to improve it. "There is a possibility that this is due to a drop in natural action of cortisone. This hormone is released in the early hours of the morning and helps us to stay active during the day. But with the passage of time, the body becomes more slow and, with it, the fever may rise, "says another general practitioner, Arnaldo Litchenstein, the Hospital das Clinicas in Sao Paulo.
