After considering the available scientific evidence that circadian and sleep health are positively affected by the availability of natural daylight during the morning and negatively affected by the twice-yearly changes of clock time, especially when the clocks move forward in spring, the British Sleep Society recommends the abolition of the twice-yearly clock changes in the UK.

With sleep being central to health and wellbeing, the Society has issued a statement saying that it “strongly recommends” for Standard Time – also known as Greenwich Mean Time (GMT) – to run throughout the year.
