Oxford named the sleepiest city in the UK by Silentnight

The research, conducted among 2,000 adults, revealed that 67 per cent of people in the city frequently feel worn out - higher than anywhere else in the UK.

Cardiff residents followed closely behind at 63 per cent, while Cambridge trailed in third place with 62 per cent.

Plymouth and Birmingham also featured within the top five cities with the sleepiest population.

Meanwhile, Newcastle earned bottom spot with just 48 per cent of its residents reporting frequent fatigue.

Responding to the findings, bedding manufacturer Silentnight, who commissioned the study, organised an on-the-street test in Oxford.

The challenge was to test residents' responsiveness by hitting as many lights as they could in 30 seconds.

Participants were then rated from "practically snoring" to "top snoozer".

Silentnight's team was on hand to giveaway free mattresses to some of the sleepiest on the day, and offer advice to help them as the clocks go forward for British Summer Time.

Silentnight's sleep expert Hannah Shore, who trained in sleep medicine at Oxford University, said: "It’s not hugely surprising to see some of the most well-known university cities in the top spot for sleepiest residents, but there are some simple steps locals can take to feel more well rested.

“Comfort and routine are key, so be sure to create a wind-down routine in the evening and ensure your space is as restful as it can be – with comfortable bedding, dim lighting, and the right temperature."

Ms Shore added that one poor night's sleep can significantly impact daily tasks, from slower reaction times to reduced concentration levels.

In the study, 56 per cent of participants across the nation reported often feeling tired.

Meanwhile, 31 per cent believed they don't get enough sleep regularly.

Blame was placed on constant busyness, long working hours, and weather conditions.

The average person feels most sluggish in the late afternoon, at around 3.47pm.

Coffee is the go-to solution to fight lethargy, followed by napping and walking.

The study also found that the average adult utters "I’m tired" three times a day.

Ms Shore added: "Sleep is so important for physical recovery but it’s also vital for our brains.

"Light sleep in particular, helps our memory, learning and with processing our emotions, but it’s often the stage we lose out on when we’re not getting enough sleep."

As the UK adjusts to the clock’s going forward, Silentnight shared three tips to improve sleep.

These were establishing a consistent bedtime routine, avoiding hitting the snooze button and letting in bright light during the day.
