If you do not "sleep well o'nights", the cause may be found in the bed or the bedding. When one changes to a certain position, either erect or reclining, numerous changes begin to take place within the body. The fluids tend to settle in the lowest part of the glands. The large organs change their relative positions. They press upon each other and pull upon the ligaments which fasten them to body walls. The weight of the body presses upon large areas of skin and muscles. The skin under pressure is in such close contact with the bedding that ventilation is prevented and it becomes over-heated. If it were possible to lie still, one would soon create a tropical climate about oneself, even on the coldest night.
