During sleep the body also goes through a complicated regulation of immune functions. Studies have shown that when people suffer from sleep deprivation or sleep is chronically restricted, their T-cells (class of white blood cells) reduce inflammatory cytokines and increase.

During deep sleep, the muscles relax and dilate blood vessels by stimulating circulation and the brain processes information.

People who suffer from chronic sleep deprivation, those who do not sleep well and pregnant women need to increase the hours of sleep. Seniors may suffer interruptions during sleep and daytime naps need.
Generally, adults who sleep less than 6 hours or more of 9 hours may have a shorter life.
In the past, studies focused on the consequences of the lack of sleep 48-96 hours. Symptoms included drowsiness, loss of hair, irritability, agitation and psychosis.
Today researchers focus on sleep restriction and what happens to people who sleep less than 6 hours per night. Some become hyperactive and restless during the day, others are tired and sleepy.

The best time to sleep
Current guidelines for good sleep hygiene advise that people go to bed at the same time and get up at the same hour, but very few investigations indicate what time you have to lie.
Dr. Chritian Gulleminault Stanford University conducted a preliminary study 8 men who spent a week in the sleep laboratory. During the investigation, attention was paid to their behavior and the level of performance in a driving simulator, on memory tests and tests to stay awake. It is the liberty of sleep 8 las primeras horas y media two nights and only 4 las otras hours 7 nights.
One group slept in 22:30hs. the 2:30hs. during 7 nights, y el otro grupo slept in 2:15hs. the 6:15hs. As was expected, the restrictions Sleep affects ALL Participantes. Los resultados de las pruebas monitor that tomaron nights later than that durmieron 8 ½ hours in comparison with the prueba de los resultados realizada the last night of dream deprivation condom very different.
There is also differentials between them but there had been two grupos. The test results in the group waking sleeping early was better than sleeping late group. The group also went to bed early had better results on tests of sleep efficiency (percentage of time they slept for four hours) and sleep latency (amount of time it took to fall asleep).
These results are not sufficient to determine the best time to sleep, but indicate that sleep at different times produces different results.
