Men and women have slightly different physiology, endocrinal physiology and body characteristics one example being men having on average greater body size weight and strength. In general yet with large individual differences women have a larger surface to mass ratio which implies that women are prone to heat loss. One the other hand women have a higher whole body and subcutaneous fat content than men which in turn increases insulation. Women are known to have colder skin at distal areas despite the increased body fat content relative to men. Part of this effect can be attributed to reproductive hormone and the menstrual phase. In general, relative to men, the thermo neutral zone of women is shifted upward (the temperature rang at which the person feels ‘comfortable)
