Twice a year the country goes through the panic of resetting its timepieces as the clocks jump forwards (and backwards) by an hour.
This year the clocks will go forward, signaling the start of British Summer Time (BST), on 29 March.
Sometimes also known as Daylight Saving Time (DST), it signals longer (and hopefully sunnier) days and warmer temperatures.
Twice a year we go through this rigmarole
Though for many it’s a longed-for signal that the gloom and doom of winter is on its way out, sadly it can also play havoc with your sleep patterns.
The time change can affect the body’s circadian rhythm (the body clock that controls mood, energy levels and alertness over a 24-hour period) and can cause stress as the body struggles to adjust.
Sleep specialist Dr Craig Hudson suggests behavioral, environmental and dietary changes to aid the transition, including the blessed advice to increase your consumption of carbohydrates (yes really!)
When the clocks go back an hour, the UK is on Greenwich Mean Time (GMT). This year this will occur on 25 October.
Debate over the effects of turning the clocks back (and forth) has been a British pastime for more than a century, when the first Daylight Saving Bill was brought before the House of Commons.
During the Second World War the Government moved the clocks forward one hour to help munitions factories maximise productivity and allow people to get home safely before the blackout.
Between 1968 and 1971 the Government carried out the same experiment but was forced to end it after complaints in Scotland and northern England.
Plans have also been mooted to move to Central European Time – something that would mean lighter winter evenings, which supporters claim would cut road deaths, boost tourism and reduce energy use.
But the proposals have faced opposition from many in Scotland who do not relish the prospect of an extra hour of darkness in the morning.
