The idea that happier people sleep less is largely a myth. While some studies have shown that people who are more content with life tend to sleep slightly less than others, this is usually by a matter of minutes and not significant enough to affect overall sleep quality.
Studies have found that people who report higher levels of happiness generally sleep for 7 to 8 hours a night, the same amount as other individuals. Although they may go to bed later and wake up earlier, the amount of total sleep is usually similar. Therefore, the idea that happier people sleep less is largely false.
The amount of sleep someone needs depends on many different factors, such as age, genetics, lifestyle, and health. Generally, adults need 7 to 9 hours of sleep per night while children need more. Some people may need more or less sleep than others, but the amount of sleep needed is generally the same for everyone.
In addition, research suggests that getting enough quality sleep is an important factor in overall happiness. Studies have shown that people who don’t get enough sleep are more likely to experience depression, anxiety, and other mood disorders. Getting enough sleep can help improve mental health and increase overall life satisfaction.
Therefore, while some people may be able to get by on less sleep than others, the amount of sleep needed for optimal mental and physical health is generally the same. People should focus on getting enough quality sleep in order to be happier and healthier.
