We need to get an adequate amount of truly restful sleep in order to function at our very best. But all too many of us find it very hard to do that.

The National Sleep Foundation believes that the majority of adults should get seven to nine hours of undisturbed sleep per night. But just 56% report sleeping as much as they need to, while 43% believe they would feel better if they were able to sleep more. And 91% of American adults report at least occasionally waking up in the middle of the night. Much of that problem has to do with their comfort while sleeping. And that’s why adjustable beds have become so popular.

Your room environment can have a negative effect upon your sleep quality. If you awaken in the middle of the night because it’s too cold or too warm and your have to adjust your sheets to compensate, you’re one of the 86% of the population for whom that’s a problem.

Sometimes simply changing your sleep position can help, and the way a lot of us do that is with adjustable beds. They have the added advantage of allowing individual settings for two sides of the same mattress to account for differing preferences.

One large survey published in 2011 found that 35% of the more than 74,000 people responding slept less than an average of seven hours a night. That has implications for public health and safety, as nearly half of those reported that they fall asleep during the day at least once a month. And one study found that a full 25% of all U.S. workers have insomnia, which each year costs employers $63 billion in lost productivity.

It’s estimated that 50 to 70 million adults in the United States have chronic sleep and wakefulness disorders. While some of them may have an underlying medical issue, a great many could benefit from simply improving the circumstances in which they try to get their much-needed rest.

And that’s where switching to one of the various styles of adjustable beds might just make all the difference. Some have optional heat and massage and can provide temporary relief of lower back pain. Serious issues such as edema or swelling of the legs, poor local blood circulation and symptoms of hiatus hernia can benefit from an improved body position. And if snoring is a problem, sleeping at an upright angle may help.
