Question

Give any two examples of preventing loss of body heat by postural behaviour in humans

Answer 1

Answer:

As in other mammals, thermoregulation in humans is an important aspect of homeostasis. In thermoregulation, body heat is generated mostly in the deep organs, especially the liver, brain, and heart, and in contraction of skeletal muscles.[1] Humans have been able to adapt to a great diversity of climates, including hot humid and hot arid. High temperatures pose serious stress for the human body, placing it in great danger of injury or even death. For humans, adaptation to varying climatic conditions includes both physiological mechanisms resulting from evolution and behavioural mechanisms resulting from conscious cultural adaptations

Answer 2

Answer:

     There is no way to prevent all heat loss of body. It can be reduced only. Two ways to prevent heat loss like conduction, convection, radiation and evaporation.

• When the temperature of the skin is lower than surroundings, the body gains heat.
• By not doing any kind of exercise, we can prevent the lose of heat of body.
