Sleep continuity disturbance impairs endogenous pain-inhibitory function and increases spontaneous pain in women. This supports a possible pathophysiologic role of sleep disturbance in chronic pain, according to a study published in the April 1st issue of the journal.
"This study finds that fragmented sleep profiles, akin to individuals suffering from middle of the night insomnia, health care workers on call, and parents caring for infants, alter natural systems that regulate and control pain, and can lead to spontaneous painful symptoms," said Smith. "Our research shows that disrupted sleep, marked by multiple prolonged awakenings, impairs natural pain control mechanisms that are thought to play a key role in the development, maintenance, and exacerbation of chronic pain."
Recent studies associate lack of sleep with serious health problems such as an increased risk of depression, obesity, cardiovascular disease and diabetes.
Experts recommend that adults get between seven and eight hours of sleep each night to maintain good health and optimum performance.
