In 2013, 17.8% of American adults reported smoking cigarettes, down from 20.9% in 2005 and 42.4% in 1956 (when the U.S. government first started keeping such records).

That's great news! But it's really important for people who already have sleep issues to stop or reduce their smoking as smoking affects the quality of your sleep in many different ways:

• Smoking increases your risk of sleep apnea (learn more about sleep apnea here)
• Smokers wake up more frequently during the night.
• Smokers have trouble falling asleep and feel restless in the morning.
• Smokers are more likely to suffer insomnia (read more about insomnia here).

If you're a smoker and have scheduled or are considering scheduling a sleep study, you're probably worried about how you'll make it through the night. Our technical director, Jonathan Sherrill addresses your concerns in this post.

The nail industry grew to $7.47 billion in 2012. In California alone, there were almost 8,000 nail salons.

Many of the patients we schedule for in-center and in-home sleep studies wear nail polish, gels or acrylics. 

Our customer service department is frequently asked whether nail polish, gels or acrylics will interfere with testing.
