Man has a remarkable ability to resist physical strains and strains and adapt to different environments. If climate change suddenly occurs, adaptation is not possible in some people, and this will lead to adverse effects. The effects of heat are seen in tropical conditions, both between natives and new entrants. Heat comes from convection and radiation and evaporation of sweat, which is the most effective. Thermal disorders are caused by the breakdown of the thermostatic mechanisms. The clinical picture can be acute or chronic
On a very hot day, the total loss can be reduced to 5-6 liters in the form of sweat with 10-12 g of salt loss. Acclimatization increases the extracellular fluid volume which is located in the extended vascular bed. This results in a reduction in pulse rate and increased heart output. Sweat glands produce even more sweat at even lower temperatures. Salt extraction can be reduced by reducing the sweat salt (2 g / l) and urine, mainly due to increased production of aldosterone. They are switched on for 10 to 14 days with adequate warming in the warm environment. Restricted individuals are able to perform well in hot climates when the water and salt intake is adequate (5-6 liters and 15-20 g / day).
Anhydrotic Heat Transfer
This is also known as tropical anhydrotic asthenia, termogenic anhydrosis characterized by depression of sweating, exhaustion and blistering of the skin on the throne (miliaria profounda)
. Sweat channels are swollen by the horns and keratocyte cells, and consequently in the absence of sweat. This will lead to fluid retention and kidney formation. Syndrome is often associated with inflammatory heat.
: Disease may occur due to newcomers or even longer than normal acclimatized persons. During the warm period, the feeling of extreme warmth, sedentary asthenia and reduced ability to work are initial symptoms. These symptoms are exacerbated by a slight effort. Tachycardia, tachypnea and mild pyrexia (38 ° C-40 ° C). Anhydrosis may extend to the whole organism or be localized. This can be for several weeks. It may be polyurethane, urine contains less chloride. Skin changes are superficial to yarn heat, but in miliary depth there is no erythema around injuries and most commonly seen in the limbs and near the body. : Clinical diagnosis is based on symptoms. Simple heat dissipation and damage should be excluded.
Treatment : Patient should be placed in a cool environment. Recovery is usually quick. Continued work in hot environments can lead to a decline
