The biggest causes of a restless night's sleep have been revealed – including feeling stressed, fretting over finances, and never being quite the right temperature

A study of 2,000 adults found 38 per cent suffer from poor sleep due to having an uncomfortable mattress, while 36 per cent struggle because of their partner’s snoring.
A successful slumber is also often ruined by traffic noise, light coming in from the window and habits such as consuming caffeinated drinks.
And mobile phones have a big impact, with scrolling through social media (14 per cent), playing games (12 per cent), and reading (13 per cent) on their devices pre-bedtime also leading to a bad night.
As a result, the average adult reckons they need an additional four hours sleep every night to make up for a lack of peaceful rest, according to the research commissioned by furniture retailer DFS [https://www.dfs.co.uk/beds-and-mattresses/beds].
Dr David Lee, clinical director at Sleep Unlimited and author of ‘Teaching the World to Sleep’ said: “We’ve seen big changes to people’s routines as a result of the pandemic, so it’s no surprise that many people are struggling to maintain or establish a good bedtime routine.
“Bad sleepers need to declutter the bedroom by establishing the bedroom as simply for sleep.
“Get dressed in a different room, read in a different room, use electrical devices in a different room.
“Then, over time, you’ll start to associate the bed in the bedroom with nothing but sleep.”
A spokesperson for DFS said: “There are ways to get a good night’s sleep, but it seems people are out of practice with a number of habits getting in the way throughout the day.
“It’s no surprise that having a poor-quality mattress or pillow is a contributing factor to an uncomfortable sleeping pattern as well as emotional and physical factors in and around the home.
“So, it’s important to ensure you have a really comfortable bed and tighten up your routine where necessary.”
