Staying up to watch TV is the main reason people don't get enough sleep.
Almost one in five (19%) says staying up too late watching programmes or films gets in the way of them getting seven or eight hours of rest each night.
18% say poor mental health and anxiety and depression negatively impact their sleep.
17% report feeling stressed about finances and 15% say stress and worry about work impact their sleep.
Twining's Sleep Census found the majority of people are sleep deprived with only 9% of us enjoying "regular undisturbed slumber", with 91% report experiencing regular and prolonged wake-ups.
A lack of sleep was also found to impact our relationships, confidence and productivity levels.
Almost a third experienced lack of productivity and over a fifth (22%) have fallen out with friends or partners because of sleep deprivation.
The poll of 2,000 adults found 59% say they regularly go to sleep and wake up at different times.
Sleep expert, Dr Guy Meadows, advises a sleep routine that is maintained across the week, including weekends.
"Try setting a 'go to bed alarm’ each day to help keep your sleep on track, and aim to keep wake-up times within 30 minutes every day to regulate patterns".
