fans create white noise. White noise is defined as, “random noise with uniform frequency spectrum over a wide range of frequencies,” by Dictionary.com, and is known to encourage deep sleep and help cure insomnia. Whether it’s your bedroom ceiling fan or a floor fan at the foot of your bed, the gentle whir blocks out all sudden variations of sounds during the night, leaving you to feel extra refreshed in the morning.


One reason a lot of people choose to sleep with a fan is that they create a white noise that can be soothing for many. One sleep expert told Huffington Post, "I sleep with a bedside fan every night, no matter what the temperature. If the fan's not on, I will definitely have difficulty falling asleep. There’s plenty of anecdotal evidence that white noise can be soothing because it blocks out sudden variations in sound—like a barking dog, or a car alarm—that can lighten our sleep or wake us." If you find that outside noises you can't control bug you, try a fan for the calming white noise.


Benefits of a Great Night of Sleep

There's nothing better than waking up after a great night of sleep, feeling refreshed and ready to tackle the day. There are so many benefits of a good night's sleep in addition to feeling rejuvenated the next morning: it can keep your heart healthy, help reduce stress and ward off depression.

You may have noticed that getting a good night's sleep is becoming tougher to achieve as you grow older. According to the U.S. National Institutes of Health, older adults who don’t sleep well at night are more likely to have problems with memory and attention and are at a greater risk of nighttime falls.

Sleep duration — that is, how much you sleep each night — has also been linked to longevity. The most beneficial night’s sleep is probably 7 to 8 hours in length. In large epidemiological studies, those get significantly fewer hours of sleep (fewer than 6) or substantially more (over 9 hours) have been shown to be at a greater risk of dying during the study period.
