Sleep is extremely relevant to the preservation of good health and strongly impacts quality of life during aging. A study by Vigeta and Brêtas (2004) found that women experienced alterations in sleep following menopause. The postmenopausal period begins 1 year after the last menstrual bleeding and is a biological milestone regard-less of whether menopause was natural or induced (Orga-nización Mundial de la Salud [OMS], 1996).
