There are diagnostic tests that can be helpful for assessing your sleep problems, with special tests for insomnia. It may be helpful to keep a sleep log or use an actigraph (like a fitness tracker) to track your sleep patterns. Further testing with an overnight sleep study called a polysomnogram can also be helpful to identify sleep apnea or restless legs syndrome as potential contributors to insomnia.
You’ve likely been told over and over again that a good night’s rest equals eight hours of sleep. But research shows it’s not the number of hours you sleep that matters the most – it’s the quality of the hours you are getting. The largest sleep study ever conducted on 1.1 million people shows that it’s quality, not quantity, that matters most. The researchers found that participants who slept only six and a half hours a night lived longer than those who slept eight hours. It’s easy to conclude that you’ll live longer if you sleep for six and a half hours a night, but the reality is more complicated. It’s possible that the healthiest people simply need less sleep. And when you’re getting good-quality sleep, you likely need less of it.
“It truly is cruel,” Simpson says. "Women may have had no problems with sleep their whole lives, except they can’t get any because their children or their job are keeping them up. Then they get the kids raised and the job slows down, and their sleep patterns go absolutely haywire. During menopause, women’s rates of insomnia go through the roof, and their rates of sleep apnea become more or less equivalent to men.”
Getting outside in the sun for 15 minutes each morning helps to regulate the production of melatonin, the sleep hormone. Your internal body clock (the circadian rhythm) runs on a 24-hour schedule and functions best when you are exposed to a regular pattern of light and dark. Malfunctions in your circadian rhythms because of changes in light and dark exposure can negatively impact your ability to get a good night’s sleep.
Use a blue light filter on your device. The blue light emitted by smartphones and tablets can be a powerful sleep disruptor. It suppresses your body’s production of melatonin and throws your circadian rhythm off, making it harder to fall and stay asleep. Luckily, many smartphones these days have a “night shift” feature that adjusts the screen from cool (blue) to warm (yellow) light, which is less likely to keep you up past your bedtime. Likewise, there are apps you can run on your laptop or tablet that reduce blue light. Some popular ones are f.lux and Twilight.
