(WXIA) -- Many people are searching for ways to help get a good night's sleep.
According to the CDC, 23 percent of people said in a survey that concentrating on certain things keeps them awake at night, followed by working on hobbies and finances.
Information from Emory Healthcare showed that insomnia affects up to 10 percent of the population.
Our morning team at 11Alive brought in an expert to talk about insomnia. Dr. David Schulman from the Emory Clinic Sleep Center says there is a difference between insomnia and trouble sleeping.
He says insomnia is difficulty sleeping for more than 30 - 45 minutes when you try to go to bed. Difficulty sleeping can happen when you're too sleepy or not sleepy enough - it's a much broader term.
When it comes to small increments of sleep and overcoming that sleep cycle where you only get a few hours of sleep at a time, Schulman says oftentimes people divide their sleep into chunks. As long as you're getting seven or eight hours of sleep in a day, it's probably low in impact.
Some are able to fall sleep, but then have trouble staying asleep due to tossing and turning. According to Schulman, the trick of going to sleep and staying asleep depends on why you're tossing and turning.
It could be environmental. For example, is there a disruption in the environment from a bed partner, the television or bright light? Schulman says if not, you might want to see a doctor. It could be something internal such as sleep apnea or leg problems.
Are you a parent trying to get your kids back into a sleep cycle now that school has started? Kids sleep in during the summer, so some school districts have explored a later start time. Atlanta has yet to try this, but Schulman recommends starting the school sleep cycle one or two weeks before the first day of classes.
Children should avoid drinking too much caffeine, he says. It's best to limit intake to two caffeine drinks per day, and avoid caffeine after lunch. Further, light and electronics need to go away at least two hours before bedtime.
Kids can be more sensitive than adults to bright lights, like those from an iPad and iPhone. Schulman says they also need more sleep than adults.
Elementary students should get ten hours of sleep per night. Kids in middle and high school do best after nine hours.
