Extreme heat events guidelines, technical guide for health care workers : Lignes directrices à l'intention des travailleurs de la santé pendant les périodes de chaleur accablant, un guide technique

For the most part, (contact of the skin with cooler objects) and the body generates more heat than is required internal conduction (contact of tissues inside the to maintain core temperature and therefore the body, which is important in heat distribution to the excess heat must be eliminated from the body. [...] The transfer of heat from the temperature gradient and occurs by conduction surface of the skin by air helps carry heat away within the tissue from the core to the skin surface. [...] It should be noted however that heat Only when the heat reaches the surface of the skin must first be conducted to the skin surface and can it be released to the environment through four then to the air and only after this is the heat finally mechanisms which include: carried away. [...] Extreme Heat Events Guidelines: Technical Guide for Health Care Workers 2. Physiology and Pathology of Heat Illness It is important to know that there are limits •. the amount and rate of sweat production by to the cardiovascular capacity of the body to sweat glands, and thermoregulate, especially when exercising in the •. the rate at which sweat is evaporated from the heat. [...] The circulatory system has to continue to transport This second factor is affected by the ability of the blood to the working muscle and concurrently ambient environment to remove the sweat from increase blood fl ow to the skin in order to transport.
