Severe burn injury over 30% or more of the body surface results in pronounced metabolic response that has prolonged nutritional implications. Understanding the nature of this response and the consequent changes in nutritional requirements is important for the optimal treatment of such patients. The expenditure of resting energy after a burn injury can be as much as 100%. Increased heat loss from the burn wound and increased beta adrenergic activity are probably both important factors that cause an increase in the resting energy expenditure. Burned skin loses its effectiveness as a barrier to water loss, leading to increased evaporative heat loss via the wound. In addition, radiation heat loss is increased from burn wounds. This is brought about by the increased blood supply to the burn wound, which is a normal response to any injury.

Insomnia may affect different people in different ways, but may affect as much as 25% of the population at some time or another and 9% on a regular basis. (Source: Carlson, 2008) How much sleep each person needs is different, so defining insomnia is difficult at best. Not everybody needs eight hours of sleep; some people may need as few as five hours while others may need up to ten hours to feel refreshed. Defining insomnia must start with defining how much sleep you personally need in order to feel at your best. Sleep is important, not only for the rest that it provides, but also because sleep is when your body recharges, refreshes and resets itself for the following day. Think of sleep as a reboot for your brain and your body.
