The British Sleep Society position statement on Daylight Saving Time in the UK

There is an ongoing debate in the UK and in other countries about whether twice-yearly changes into and out of Daylight Saving Time (DST) should be abolished. Opinions are divided about whether any abolition of DST should result in permanent Standard Time, or year-long DST. The British Sleep Society (BSS) concludes from the available scientific evidence, that circadian and sleep health are affected negatively by enforced changes of clock time (especially in a forward direction) and positively by the availability of natural daylight during the morning. Thus, our recommendation is that the UK should abolish the twice-yearly clock change and reinstate Standard Time throughout the year.
