New Survey Links Healthy Sleep Habits with Better Well-Being
The data is based on interviews with 7,058 U.S. adults conducted from September 5 to 19, 2014 and the results found that Americans who get more sleep reported having a higher overall well-being (which according to Gallup-Healthways consists of a positive outlook in areas of life that include purpose, social, financial, community and physical health) when compared with Americans who get less sleep.
According to Gallup, the positive relationship between sleep and well-being peaked at eight hours per night, which is on par with the National Sleep Foundation's sleep recommendation of seven to nine hours per night for adults age 26 to 64.
The well-being score for Americans who sleep eight hours per night was 1.5 points higher than those who reported sleeping seven, only a slight difference when compared to the 4.8 point "advantage" that those who sleep for seven had over those who sleep for six.
Although the survey found a "strong link" between sleep and well-being, the results do not reveal the direction of the relationship. In other words, there's no indication as to whether healthy sleep habits boost well-being or if those with higher levels of well-being are more inclined to get more sleep.
Either way, with the survey having found that about 42 percent of U.S. adults get less than seven hours of sleep each night, and with many other studies having revealed the importance of getting adequate amounts of sleep on a regular basis, it's clear that more Americans could benefit from aiming to improve their sleep habits as a means of bettering their overall health.
