Sleep is the payback period for the body, during this period in which we are unconscious body is still working to restore its functions. In fact, the number of hours of sleep is directly proportional to the level of stress. People sleep less when they are on alert and vigilant (You need to generate more cortisol which is a stress hormone) or have a restless sleep and not the fault of the mattresses. The technology, work and concerns can affect the quality of sleep, but it is important to form habits to sleep better.
Here I leave a link to look at options womens pajamas and give you reasons to sleep better:
