The time you spend working is the single most important factor that has an impact on your sleep, reveals a new study.
The study, by researchers at the University of Pennsylvania, was carried out on nearly 50,000 US participants.The participants were questioned on three different occasions - in 2003, 2004 and 2005 - and asked how they spent their time between 4am the previous day and 4am that day.
The researchers found that the more hours people work, the less sleep they get.
Dr Mathias Basner, and his colleagues found that people who get less than four-and-a-half hours sleep a night worked an average of 93 minutes longer on weekdays and 118 minutes more at the weekend.
People who slept 11-and-a-half hours or more were found to work an average of 143 minutes less on weekdays and 71 minutes less on weekends.
The researchers also noted that short sleepers also spent more time socialising, studying and doing housework, reports the BBC.
