An online survey of more than 1,000 people scored their happiness level in relation to how much time they snoozed during the day. Participants were divided into three groups: those who don't nap, short nappers of 30 minutes or less, and long nappers of 30 minutes or more.
Two-thirds of short nappers (66 percent) reported feeling happy, compared with 60 percent of non-nappers, and 56 percent of long nappers. On the happiness scale, short nappers scored 3.67 (out of 5), versus 3.53 for non-nappers, and 3.44 for long nappers.There was a noticeable age difference, with younger people (aged 18 to 30) who tend to sleep less at night making up for it with longer daytime naps, compared with 30 percent of people over 50.
"A large body of research shows that short naps boosts performance," Wiseman says, adding that companies like Google have installed employee nap spaces. But be warned, the benefits of "nappiness" disappear the longer you linger on the couch.
Wiseman says "longer napping is associated with several health risks," and frequent hour-long naps have been linked with an 82 percent rise in heart disease, notes the Huffington Post.
