What to expect during a sleep study

A sleep study, also known as polysomnography, is an evaluation of physical and brain activity that occurs during sleep. Brain waves, eye and leg movements, heart rate and oxygen levels are all recorded and measured during this exam. Sleep studies can confirm the type of sleep disorder you have. For example, someone experiencing what appears to be insomnia may actually have sleep apnea.

At each of our sleep centers, you will find a home-like atmosphere designed to make you feel as comfortable as possible during your sleep study.

Sleep disorders we treat

It can be easy to dismiss sleeplessness as "a part of getting older", but studies show lack of sleep negatively impacts your health. Not getting enough sleep can cause a variety of health complications, including high blood pressure (hypertension), diabetes, heart disease, sexual dysfunction and other chronic illnesses.

According to the American Sleep Association, 50 to 70 million Americans have a sleep disorder. Some of the most common sleep disorders we treat include:

  • Insomnia - This is a sleep disorder marked by the inability to fall or stay asleep, or waking up several times throughout the night. Treatment for insomnia may include relaxation techniques, light therapy, prescription medication or cognitive behavioral therapy.
  • Narcolepsy - This sleep disorder causes excessive sleepiness and a tendency to fall into rapid eye movement (REM) sleep often and quickly. Other symptoms may include atonia (sleep paralysis), cataplexy (sudden but brief loss of muscle control, generally caused by a strong emotion) or a complete loss of muscle control.
  • REM behavior disorder - This is a rare sleep disorder that causes people to physically act out their dreams and sometimes vocalize during sleep.
  • Restless leg syndrome - This nervous system disorder disrupts sleep by causing a "pins and needles" sensation from the waist down. This creates an uncomfortable sensation and desire to move the legs. The constant movement and sensation makes it difficult to fall asleep.
  • Shift working disorder - When work hours at night overlap with typical sleeping hours, it can disrupt the circadian rhythm. This rhythm is your body's natural way of regulating sleep. When it is disrupted by atypical sleeping/waking hours, it causes excessive sleepiness, difficulty concentrating and irritability.
  • Sleep apnea - Sleep apnea occurs when muscles in the back of the throat relax and cause the airways to narrow or close. This interrupts breathing, sometimes hundreds of times a night. In obstructive sleep apnea, this may happen because of congestion, smoking, alcohol use, naturally narrowed airways or obesity. In central sleep apnea, the brain does not send proper signals to the muscles that control breathing.
  • Sleepwalking - Sleepwalking is also known as somnambulism. It may include walking, talking, sitting up in bed or performing complex physical tasks without memory of the event.

Some sleep issues can be caused by breathing disorders. Our sleep medicine specialists collaborate with experts in pulmonary care to help you breathe and sleep better.

Pediatric sleep medicine

Children can have sleep disorders and trouble sleeping as well. The specialists in our pediatric sleep center conduct sleep studies for children in a calm, stress-free environment. We can help your child get the rest they need, ultimately helping you sleep better, too.
