During the cold season, a lack of food, Bats spend įmygyje – the maintenance of a high body temperature would not be wasted energy, these mammals body temperature by about 30 ° C, and it is close to the ambient, in winter, temperature. At the same time bearing all the vital processes slow down: decreases breathing, heartbeat. Although the vital processes slow down, thermoregulation mechanisms cease to operate, therefore exposed to a risk, or a material change in the ambient temperature, using your body fat accumulation bats can raise the body temperature to normal and wake up. Awakened bat reacts immediately, though he'd wake up completely some time - about 20-30 minutes, through the consumption of the whole winter through the summer įmygiui accumulated fat reserves.
