British Summer Time (BST) from Greenwich Meantime (GMT). Clinical psychologist Dr Julie Smith explained: "In springtime when the clocks go forward one hour, the conversation tends to be about missing one hour of sleep in just one night. But most people will notice that it can take much longer than a day to adjust. "In the weeks that follow it can feel much harder to get up each morning and much more difficult to fall asleep at your usual bedtime." If you're used to sticking to a routine, even an hour difference is enough to cause disruption for days on end. But thankfully, there are ways to combat feelings of fatigue. According to , Dr Julie says it's important to introduce small changes in your routine early – starting now. All you need to do is adjust your bedtime by 15 minutes at a time, which should feel a lot less draining than a whole hour does. The doctor explained: "Your biological clock cannot shift a whole hour in just one 24-hour period, so start in advance. In the week leading up to the clocks changing, start your bedtime routine 15 minutes earlier and set your morning alarm 15 minutes earlier. "This way you won't feel the sudden shock to the system of losing that hour of sleep and will feel much more ready for the new schedule." The UK's clocks always go back by one hour on the last Sunday in October and forward by one hour on the last Sunday in March. This method is also used in some other countries across the world, but many don't need to do this. Most smart phones, computers, and other devices connected to the internet will update the time automatically. But if you have a watch or clock that isn't digital you may need to change the time yourself.
