When do the clocks change and why do we do it?
Every year UK clocks undergo two changes - the first in the spring and the second in the autumn.
In spring the clocks go forward, before going back to their original time in autumn.
With signs of spring now starting to clearly appear, it is not long until we see the clocks change for the first time in 2025.

So when exactly will the clocks change this year, and what impact will this have?
The clocks will go forward on Sunday 30 March at 1am by one hour.
This marks the UK's transition into British Summer Time (BST) where there is more daylight in the evenings and less in the mornings.
This period is also sometimes known as Daylight Saving Time.
Due to the change in the clocks, the Met Office expects sunset on Sunday for Manchester to be 7:41pm.
But the change will see darker mornings, with the Met Office expecting Manchester to see sunrise at 6:47am on Sunday morning.
As clocks go forward the UK will lose one hour from the day.
The transition to BST will also see later sunsets from Sunday for the UK - but early risers will initially notice darker mornings.
These changes could impact energy levels, as researchers have found important links between exposure to light and overall productivity.
Dr Ashleigh Johnstone, senior lecturer in psychology at Arden University, explains: 'Exposure to more natural light in spring boosts mood and energy levels as it increases our serotonin supplies – a neurotransmitter that's linked to happiness and wellbeing.
'The brighter season also helps regulate our circadian rhythms, leading to better sleep and improved alertness.'
This year the clocks will go back on Sunday 26 October at 2am by one hour.
This will mark the UK's return to Greenwich Mean Time (GMT).

When and where Saharan dust storm and 'blood rain' could hit the UK this week
The UK's topsy-turvy weather is set to continue this week, with forecasters hinting at the possibility of 'blood rain' heading to UK shores. A brief blast of heat is expected for much of the country later in the coming days - only to quickly be replaced by torrential rain. And, what's more, it is predicted the downpours will bring with it some Saharan dust. Here, Yahoo News UK looks at exactly what Saharan dust is and what it could mean for the coming days. It's a mixture of sand, detritus and dust from the Sahara Desert that have been blown thousands of miles by strong winds in the upper part of the atmosphere as far north as British shores. However, for it to end up on the ground, it needs to be carried there by a meteorological vehicle, such as rain. According to the Met Office, Britain's official forecaster: "As raindrops fall, they collect particles of dust on the way down. Then when the raindrops land on something and eventually evaporate, they leave behind a layer of dust." This is sometimes referred to as 'blood rain'. According to Met Office forecasters, there are currently "hints of a little bit of Saharan dust in the atmosphere on Thursday and perhaps Friday". Thunderstorms forecast for later in the week will "potentially wash any sand out of the atmosphere". Heavy rain is currently expected to start in Northern Ireland, western Wales and south west England on Wednesday night, before moving north and east over Thursday. This is then predicted to be followed by a second band of rain following the same pattern over Friday and Saturday. However, downpours are also expected to be preceded by high temperatures, reaching almost 30C in parts of southern and central England. Met Office Deputy Chief Meteorologist, Mike Silverstone, said: 'After largely benign weather early in the week, some intense, thundery showers will move in on Wednesday evening. "These thunderstorms are being triggered by some warm, humid air that is moving into the UK from the south. The intense rainfall could see 20-40mm accumulating over just a few hours, which could cause some disruption. "While there are no severe weather warnings issued at the moment, it is possible thunderstorm warnings may be issued this week.' The most obvious impact most will see from 'blood rain' is a reddish residue left on cars, pavements and garden furniture. In 2022, Saharan dust left a red tinge to snow at ski resorts in the French Pyrenees, while staff at Legoland in Germany had to deploy jet washers to hose down attractions before visitors arrived. BBC weather presenter Carol Kirkwood advised the public to keep an eye out for "impressive sunrise/sets" as a result of the phenomenon. However, it can also have more serious consequences, particularly for people with respiratory conditions, such as asthma, COPD or bronchitis. 'If there's a lot of air pollution in the air [and] if you have a pre-existing lung condition, those fine particles can get into your airway and irritate airways that may already be inflamed," said Karen Spillett, deputy head of health advice at Asthma and Lung UK. "If you're out and about and you have a reliever inhaler, make sure you've got that reliever inhaler with you.' She added: 'If you do start to get symptoms — that might be coughing, wheezing, tightness across your chest, feeling a bit more breathless — you can take that reliever inhaler and that can hopefully help with your symptoms.' One of the last widespread instances of Saharan dust affecting Europe was in March 2022, when parts of Germany, Spain and France all found themselves blanketed with a layer of red debris. But it has also struck more recently, such as last month, when the phenomenon left a brown haze hanging over Athens, the Greek capital. And last year, dust clouds over Italy saw temperatures in June approach 40C. Closer to the dust's starting point, in Africa, a dust storm in Senegalese capital Dakar shortly before Christmas reduced visibility to less than 500 metres.

CBT-I works for '70% of patients' — the Headspace Sleep Advisor on therapy for insomnia
When you buy through links on our articles, Future and its syndication partners may earn a commission. According to the American Academy of Sleep Medicine, 12% of US adults are diagnosed with chronic insomnia, a disorder that makes falling asleep and staying asleep difficult. While treatment for insomnia can include medication, more and more people are turning to CBT-I (Cognitive Behavioral Therapy for Insomnia). This form of therapy is designed to address the root factors contributing to insomnia, rather than just medicating symptoms. But how effective is it? We spoke to Dr Aric Prather, Sleep Advisor to wellness app Headspace, and the Director of the Behavioral Sleep Medicine Research Program at the University of California at San Francisco, to find out more following the launch of Headspace's new CBT-I sleep programme Finding Your Best Sleep. Here's what he told us... "Cognitive Behavioral Therapy for Insomnia (CBT-I) is the gold-standard empirically supported treatment for insomnia, and should be the first line treatment for individuals with insomnia before embarking on pharmacologic treatment," says Dr Aric. CBT-I also addresses the anxiety that develops with unpredictable sleep "Unlike hypnotic medication, CBT-I addresses the perpetuating factors that drive insomnia, and provides the patient with science-backed strategies to improve sleep by consolidating sleep and entraining their circadian rhythm. "CBT-I also addresses the anxiety that develops with unpredictable sleep by incorporating relaxation techniques and psychological strategies like cognitive restructuring. "The goal is to help patients better regulate their sleep, find some success in sleeping, and build confidence and resilience." "CBT-I focuses specifically on sleep and insomnia symptoms. Unlike other CBT therapies, CBT-I is heavily behavioral. We know quite a bit about what regulates our sleep biologically, so that's where we start. "Focusing on standardizing someone's wake up time, implementing stimulus control to reduce cognitive arousal in bed, and tracking sleep behavior via a sleep diary followed by restricting their time in bed to increase sleep consolidation can go a long way towards increasing the predictability at nighttime and reducing anxiety prior to and during the night." "CBT-I can certainly improve anxiety symptoms. In fact, several clinical trials demonstrate that individuals randomized to CBT-I show significant reductions in anxiety symptoms compared to those randomized to control conditions. "This isn't surprising given that poor sleep often leaves people more 'on edge' and anxious. Headspace also offers a guided program specifically for anxiety and depression, the CBT for Anxiety & Depression program, which incorporates CBT techniques specific to improving anxiety and depression symptoms. "The course has been shown to decrease anxiety & depression symptoms, improve sleep quality and positively impact mental health and wellbeing (results currently being prepared for peer review)." "Some people tend to benefit more from CBT-I than others, though much more research is needed to clarify these differences. There is little downside [to CBT-I], and it's likely to provide you with a greater sense of control over your sleep "There is some evidence that shorter sleepers with insomnia- those sleeping less than six hours, for example- may struggle with CBT-I more than longer sleepers. "This is likely because one of the active mechanisms for why CBT-I is effective is through time in bed restriction, which may not be as powerful in those already getting little sleep. "In my clinical experience, CBT-I may also be less effective in individuals with complex psychiatric or medical presentations. "In some cases there may be conditions or medications that are impacting sleep where CBT-I may not completely resolve the sleep concern." "While CBT-I remains the gold standard for treating insomnia, it isn't always accessible. Headspace's sleep course 'Finding Your Best Sleep' was created to expand low-cost access to effective sleep support. Unlike sleep medications, CBT-I does not carry any long term risk "The course expands access to proven sleep support by offering expert-led, self-guided sessions that can be completed anytime, anywhere. Included with a Headspace membership, it offers flexibility and affordability—removing common barriers to care. "The course has been clinically proven to improve insomnia after practicing just 10 minutes a day over the course of 18 days. "I hope that anyone who is struggling with insomnia will consider a trial of CBT-I in any way that is accessible to them. There is little downside, and is likely to provide you with a greater sense of control over your sleep experience. "Unlike sleep medications, CBT-I does not carry any long term risk. Moreover, the strategies learned through CBT-I can be useful well into the future and sleep changes as our lives unfold." "My suspicion is that stress and feelings of uncertainty are the most likely culprits of insomnia. For so many- too many- we feel like we are in a state of hypervigilance, and this results in nights of disturbed sleep. In turn, we often lack the emotional resources to deal with the stressors the following day, leading to yet another night of poor sleep. Thankfully, programs like CBT-I can help provide a roadmap to better regulate our sleep, and when coupled with stress management strategies, can help us cope with this stressful world." "First, I would say that they are not alone. In fact at least 30% of adults, if not more, are not getting adequate sleep. The second piece of advice is to take stock of your sleep life. Is it that you are getting sleep but don't feel refreshed? At least 30% of adults, if not more, are not getting adequate sleep "Is something disrupting your sleep? Are you so pressed for time that you are not giving yourself enough opportunity? The answer to these questions will lead to different solutions. "If you are worried about your sleep, the first step could be to talk to your doctor to make sure that you don't have a sleep disorder, like sleep apnea, disrupting your sleep. "If not and you're looking for a personalised approach, consider trying CBT-I through a sleep specialist, I always suggest that people explore the Society for Behavioral Sleep Medicine directory to find someone in their region."
