The physique’s major weapon to cease overheating is sweating. As sweat evaporates, it cools the physique.
However humid situations scale back the effectiveness of sweating because the moister the air, the much less moisture can evaporate from the pores and skin. Because the physique overheats – and heatstroke units in – the flexibility to sweat shuts down, and the physique’s temperature can spiral increased.
Extreme sweating additionally places a pressure on the guts. It has to pump more durable to ship blood, which carries warmth from inside the physique to the floor.
The hazard mounts because the physique’s inside temperature heats up previous its regular degree. Between 39C and 40C, fatigue units in as our mind tells our muscle tissues to decelerate.
