Sensitivity has many shades of meaning but most relate to your response to your environment â either physical or emotional. Sensitivity to cold means youâre quick to notice the slightest chill â in the air or in another personâs actions. A sensitivity to pollen means youâre sneezing any time itâs in the air â you just always seem to react to it. Itâs the same with emotions â sensitivity means you pick up on the feelings of others.
Also, your normal body temperature changes by as much as 1Â°F (0.6Â°C) throughout the day, depending on how active you are and the time of day. Body temperature is very sensitive to hormone levels and may be higher or lower when a woman is ovulating or having her menstrual period.hen you are too hot, the blood vessels in your skin expand (dilate) to carry the excess heat to your skin's surface. You may begin to sweat, and as the sweat evaporates, it helps cool your body. When you are too cold, your blood vessels narrow (contract) so that blood flow to your skin is reduced to conserve body heat.
