The study, conducted by sleep technology brand, Simba lays bare the impact that summer and hot weather have on the nation’s sleep.
Sweltering Brits miss out on 17 precious hours of sleep per month during the summer, compared to other seasons.
While over a third (37%) are unaffected by soaring temperatures, the vast majority (63%) admit their sleep is disrupted during hot weather, according to fresh data from sleep tech company Simba.
Over half of British adults (56%) sleep six hours or less in the summer, compared to just 39% in winter.
The average Brit revealed they sleep 6 hours and 7 minutes per night in summer, less than the seven to nine hours recommended by the NHS.
The study of 2,017 UK adults reveals UK adults miss out on an average of over two full days of sleep in the summer due to difficulty when temperatures soar.
A quarter (25%) have even had to take days off as a result of not getting enough rest and feeling too tired, with two-thirds (66%) admitting to being less productive as a result of not having enough shut eye.
To make up for lost sleep, over a third (40%) of adults confess to drinking more coffee and energy drinks than usual to hide their tiredness while 33% per cent turn to sugary sweets.
Many have devised strategies to outsmart the sweltering conditions. 29% of respondents ditch their pyjamas in an effort to cool down, while 36% percent opt for a topsy-turvy approach by sleeping on top of their duvet.
Lisa Artis, Deputy CEO of Simba’s charity partner, The Sleep Charity, said. "While the UK isn't typically associated with blistering summers, we've witnessed an increase in sweltering temperatures and heatwaves in recent years. Consequently, many struggle to sleep at night due to the discomfort of excessive heat.”
"In contrast to other nations where household air conditioning is commonplace, many Brits experience tossing and turning, unable to find comfort, and waking up frequently throughout the night."
“This restlessness prevents REM sleep, which is a crucial stage within our sleep cycle that allows our body to revitalise and heal itself.”
"It’s no surprise that 66% feel less productive at work and 25% have taken days off due to fatigue. Sleep is the ultimate health boost we can get, so it’s important to prioritise our sleep and uncover personalised sleep hacks that suit us during the summer months."
When it comes to lights out, nearly a quarter (22%) of couples find themselves retreating to separate beds in a bid to catch some cooler Zs. Furthermore, the most common squabbles among overheated partners include whether to have the duvet on or off (18%), excessive fidgeting (20%), and disputes over how long to keep a fan on (16%).
