Sleep Studies

A sleep study, also known as a polysomnogram, is a non-invasive procedure typically requiring a one to two night stay in a sleep facility. During a sleep study, a sleep technician records your biological functions,  including eye movement, muscle tone, heart rhythm, brain wave activity, and breathing, while you sleep. By looking at these biological functions, your doctor can diagnose or rule out a sleep disorder or any conditions that can compromise your health

Not getting enough sleep could be bad for your heart, according to a small new study.The study, presented at the Experimental Biology 2013 meeting, shows that sleep deprivation may have negative effects on the functioning of our blood vessels and our breathing control -- and getting more sleep could improve these functions.The study included eight healthy adults ages 20 to 35. For two nights, the study participants slept eight hours a night. Then, for three nights, the study participants only...

ABSTRACT:STUDY OBJECTIVES:To determine how aging affects the impact of sleep deprivation on blood pressure at rest and under orthostatic challenge.DESIGN:Subjects underwent a night of sleep and 24.5 h of sleep deprivation in a crossover counterbalanced design.SETTING:Sleep laboratory.PARTICIPANTS:Sixteen healthy normotensive men and women: 8 young adults (mean 24 years [SD 3.1], range 20-28 years) and 8 elderly adults (mean 64.1 years [SD 3.4], range 60-69 years).INTERVENTIONS:Sleep deprivation...
Playing sounds with certain rhythms could enhance memory during sleep, new research suggests.A small study published in the journal Neuron shows that when sounds are played during sleep that go along with the slow oscillations in brain waves that occur during sleep, that actually helps to enhance memory.The findings show "a straightforward tool for clinical settings to enhance sleep rhythms," study researcher Dr. Jan Born, of the University of Tubingen in Germany, said in a statementFor the...
Tonsil and adenoid removal improves a variety of symptoms in children with moderate sleep apnea, but "watchful waiting" also helped in some ways, a new study found.Overall, the surgery resulted in better sleep, less restlessness and impulsivity, and improved quality of life for most patients. But nearly half of children in the "watchful waiting" group also saw sleep improvements. No correlation was found between the surgery and improving attention and brain function."If you ask me what, as a...

ABSTRACT: OBJECTIVES:To inform the debate over whether human sleep can be chronically reduced without consequences, we conducted a dose-response chronic sleep restriction experiment in which waking neurobehavioral and sleep physiological functions were monitored and compared to those for total sleep deprivation.DESIGN:The chronic sleep restriction experiment involved randomization to one of three sleep doses (4 h, 6 h, or 8 h time in bed per night), which were maintained for 14 consecutive days...
