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. Restless legs is a relatively common condition, normally exacerbated by pressure to the hips when sleeping in the side position. It is much misunderstood, but increasingly suggested by specialists that excessive pressure to the soft tissue and muscle surrounding the hips causes these muscles to become traumatised with reduced circulation, resulting in stimulation of the limbs. Sleep should be a fully remedial and refreshing experience.
