Detailed explanation-1: -Acclimatization is the beneficial physiological adaptations that occur during repeated exposure to a hot environment. These physiological adaptations include: Increased sweating efficiency (earlier onset of sweating, greater sweat production, and reduced electrolyte loss in sweat).

Detailed explanation-2: -The adaptations include improved sweating, improved skin blood flow, lowered body temperatures, reduced cardiovascular strain, improved fluid balance, altered metabolism, and enhanced cellular protection.

Detailed explanation-3: -Heat stress increases the total metabolic rate and anaerobic participation during submaximal exercise, and these increases are somewhat abated by heat acclimatization. Exercise-heat stress reduces hepatic blood flow and increases hepatic glucose release.

Detailed explanation-4: -Cold adaptation is of three types: adaptation to extreme cold, moderate cold, and night cold. Extreme cold favours short, round persons with short arms and legs, flat faces with fat pads over the sinuses, narrow noses, and a heavier-than-average layer of body fat.
