Washington: Slow-wave or deep sleep may be the controlling factor in the onset of puberty, rather than the involvement of any brain part in this process, says a US study.Previous studies have shown that the parts of the brain that control puberty first become active during sleep, but the present study shows that it is deep sleep, rather than sleep in general, that is linked with this activity."If the parts of the brain that activate the reproductive system depend on deep sleep, then we need to be concerned that inadequate or disturbed sleep in children and young adolescents may interfere with normal pubertal maturation," said Harvard researcher Natalie Shaw, of Massachusetts General Hospital and Boston Children`s Hospital, who led the study."This is particularly true for children who have been diagnosed with sleep disorders, but may also have more widespread implications as recent studies have found that most adolescents get less sleep than they require," the Journal of Clinical Endocrinology and Metabolism (JCEM) reports.
