Quality sleep is an elusive commodity for millions. The complex process of attaining a quality sleep pattern can be compromised by the wrong mattress. Of course, there are many factors that can affect sleep, not least the taking of alcohol at night to aid the sleep process. Unfortunately, this is only a short term solution, as alcohol affects the natural melatonin produced, which is the hormone governing the sleep pattern. The sleeper will often wake after a few hours, and be unable to get back to sleep.
Stress is an important factor when trying to physically get to sleep in the first place.
Muscles will be tense, blood flow decreased, the brain will be overactive. The reduction of pressure will normally enable those with difficulty in staying asleep, to sleep for longer periods. Profound sleep can have side effects if the individual has postural problems. Lying in the same position for long periods, where some form of pelvic dysfunction is identified, will certainly result in substantial muscle spasm in the lumbar area on waking. Restlessness during sleep can be extremely frustrating for many individuals, as there is often an uncontrollable urge to continually reposition themselves before, and during sleep.
