During the 24 hours the propensity for sleep has two peak current: the door of sleep after a long day and early afternoon siesta.

According to the criteria of Rechtschaffen and Kales, polysomnography (electroencephalography, electromyogram and elettrooculogramma) allows didtinguere 5 stages of sleep, NREM sleep or light, 1st and 2nd, deep sleep or deep NREM, 3rd and 4th or slow wave sleep and REM sleep with rapid eye movement and the study of these phases allows us to study and define the concept of sleep cycles, which are 4 or 5 in the adult per night, and begin with steps 1 and 2, then 3 and 4 and physiological terms with REM sleep, each cycle lasts 90-120 minutes. where the latter is more abundant in recent cycles

Insomnia is a common disorder known as adulthood, but also the youth age groups are affected, between 15 and 24 years, with a prevalence of 45.5% compared to 49.4 for adults . The greater susceptibility of women is confirmed by several studies. The disorders are most complained about sluggish induction and its maintenance
Insomnia is divided into primary and secondary in the former is not possible to highlight a cause, the other is correlated with systemic medical conditions, taking drugs ... and can be correlated with hypertension and cardiovascular risk in a vicious cycle where one influences the other diseases.

Insomnia is characterized by:

Difficulty sleeping;
Night awakenings
morning awakenings
sleep is not deep enough.
Sleep, however, it is important for the psycho-physical individual, where a good night's sleep in the individual determines a minor irritation, better physical fitness, anxiety and resolve memory problems.

First, the bed must be comfortable, the patient must have completed the "traditional rituals" for example. read a good book, watch TV, hot milk, which increases serotonin (the substance that calms us) etc..
the room should be cool but not too hot but not too much and sufficiently ventilated;
if there are heart problems, the cushions will be two, and the subject is raised, the same if there are problems associated with respiratory failure or respiratory mechanics;
if the nose is closed, you can use a decongestant nasal spray;
if there are problems with debts .... solve them (is' na word!)
if you fight with your partner let the gossip!
.

then goes to drugs:
begin with the teas, the soluble camomile, valerian (are counter products that you buy at pharmacies or herbal)
to sleep better, temazepam, triazolam, estazolam, zolpidem, zaleplon;
for night-time awakenings: flurazepam, nitrazepam, lormetazepam, quazepam.
then the doctor will prescribe a tranquilizer minor example. lorazepam, zolpidem zaleplon, diazepam ....
if this did not work, it means you are stressed or depressed ..
in this case a great vacation does not hurt .. or try Milazzo Lipari, in the autumn!
