However there is a higher mortality risk if a person is consistently getting less than five hours sleep or more than nine hours sleep, compared to people who are consistently sleeping around six to seven hours a night throughout the week.
It's not so much about being able to store up sleep, but he thinks short sleepers who are changing their habits on the weekends are making up for some of what they lost during the week.
"The duration of sleep is important for longevity", said Thorbjorn Akersted of the Stress Research Institute in Sweden, quoted by The Guardian.
The Centers for Disease Control and Prevention recommends adults aged 18-60 get at least seven hours of sleep per night.
"The results imply that short (weekday) sleep is not a risk factor for mortality if it is combined with a medium or long weekend sleep", the researchers wrote in the study.
Those who enjoyed eight hours of sleep during the week and weekend were found to have a lower mortality rate meaning they lived longer.
The study wasn't ideal and had limitations, including study subjects not being observed directly and self-reporting their sleep habits.
Sleep is something you need to replenish regularly if you don't want to hurt your health. He was not involved in the new study.
While the majority of people would be able to attest that a good night's is imperative for a healthy well-being, many wind up depriving themselves of rest as they go about their busy regimes.
