I tried five simple expert-approved tricks for better sleep – and the results were incredible
As a fitness writer, I speak to elite athletes and industry-leading experts on a regular basis. In each chat, I raid their brains for all the accessible ways Independent readers can improve their health, fitness and performance. And without fail, one tip crops up time and time again: improve your sleep.
However, it's also the advice I've found people are most resistant to. Many will happily train for an hour, splash their cash on recovery tools and supplements, or even dip their toe in the waters of biohacking for marginal health gains. Yet suggesting they fine-tune their slumber is invariably met with excuses.
This is understandable. Most of us are busier than ever and time is a rare commodity; hunkering down and hitting the blanket prescription of eight hours per night isn't an option for the majority of people. But there are easy ways to improve the quality – if not quantity – of your sleep, and feel all the better for it.
Supercharging your sleep can boost your heart health, increase your energy levels, improve your exercise performance (and the myriad physical benefits that come with it) and even aid weight management. Plus, as someone who's tried tweaking their routine to improve their sleep, I can subjectively say it's had a more significant impact on how I feel than any other change I've made.
Here are the expert-approved tips I used to experience the benefits above, and many more besides.
Sleep regularity
Sleep regularity is almost on par with sleep duration in its importance for our long-term health, The Sleep Scientist founder Dr Sophie Bostock tells me. This relates to our circadian rhythm – an in-built body clock linked to every cell in the body, which is hard-wired to work to a 24-hour cycle.
Disrupting this rhythm with irregular sleep throws our body off-kilter. Dr Bostock says this is why shift workers are more likely to struggle with conditions such as fatigue, depression and heart disease.
The National Sleep Foundation reinforces this point. In a 2023 consensus statement published in its Sleep Health journal, it concludes: 'Consistency of sleep onset and offset timing is important for health, safety and performance.'
Actionable takeaway
Try to establish a regular routine, going to bed and waking up at a similar time each day.
Sleep is highly individualised so finding the right routine for you will involve some trial and error.
Pick a schedule to start with, such as 10pm until 6am, then if you don't feel well rested after a few nights, Dr Bostock advises giving yourself an extra 15 or 20 minutes in the morning.
A good sign these tweaks are working is if you start rising naturally a few minutes before your alarm.
Diet and sleep
Sleep and diet are surprisingly intertwined; if you make favourable tweaks to one, the other will benefit.
'Sleep is something that can help with weight management,' says Fat Loss Habits author Ben Carpenter. 'Just a single night of sleep deprivation can skew appetite hormones to the point that people will eat more the next day.'
A 2023 study published in the Obesity journal found that acute sleep deprivation reduces blood concentrations of the hormone leptin, which is responsible for sending signals to the brain saying you feel full. There is also an increased blood concentration of ghrelin – AKA, the hunger hormone – so poor sleep can hamper your fat loss efforts.
But there are things you can do in your diet to improve the quality of your sleep. Two of the most straightforward are avoiding caffeine in the eight hours before bedtime, and leaving at least two hours between your last meal and nodding off.
Eating tells your body there are still things to be done, as your food needs to be digested, and we all know caffeine's stimulating impacts. Avoiding these two things before bed will help you access deep sleep more easily when it's time to hit the hay, Dr Bostock says.
Actionable takeaway
Avoid caffeine in the eight hours before sleep.
Finish your last meal at least two hours before sleep.
Manage your screen time
You've probably guessed this already, but phones are far from helpful when you're trying to get a good night's sleep.
Speaking ahead of an appearance at EE Learn Live, Joe Wicks tells me that banning his phone from the bedroom and investing in a Lumie alarm clock (which wakes you up with a gradual sunrise-esque light, rather than a sharp tone) is 'the most transformative thing' he's done to improve his snoozes. And as a father of four, he needs to make the most of his time between the sheets.
'Sleep is the first thing to prioritise if you want to improve your health,' Wicks says. 'When you're sleeping well, the food and exercise side of things becomes a little bit easier. If you remove the phone from your bedroom, you're way less likely to doom scroll, to wake up in the night and check your phone or to lay in bed for an extra hour in the morning.'
Blue light – alertness-boosting light emitted from smartphones and TVs, among other things – has long been held responsible for disrupting our circadian rhythm and, consequently, sleep. But a 2024 theoretical review published in Sleep Medicine Reviews suggested there are other, arguably more important, factors at play. For example, screen time delaying when we head to bed, or technology in the bedroom disrupting our sleep.
'For some individuals and families, removing technology from bedrooms overnight could be a helpful way to prevent any possible impacts of technology use on sleep,' the report states. 'However, restricting devices may not suit everyone, or for some families this could be difficult to implement.'
To mitigate the negative impacts of technology on your sleep quantity and quality, it instead recommends managing your evening screen time using the tricks below.
Actionable takeaways
Light
The body works to a 24-hour circadian rhythm. This is informed by zeitgebers or 'time-givers' – signalling systems that tell the body what time it is and how to behave. And the strongest of the lot is light.
When bright light hits the receptors on the back of the eye, your body takes this as a sign that it's time to be awake and alert, Dr Bostock tells me. For this reason, 2023 BMX freestyle world champion and Olympic silver medallist Kieran Reilly likes to keep his home dimly-lit ;later in the day.
'My girlfriend hates it because I try to have minimal light in the house as soon as it gets to the evening,' he laughs. 'I would rather walk around with my phone torch out than switch a light on. I'm trying my best to get into that sleep mode and get tired.'
Dr Bostock recommends lighting a candle with dinner to kickstart proceedings, then keeping the lights in your home low from this point on. This can also help you establish a regular pre-bed routine, which is another way of readying your body for rest.
Inversely, Dr Bostock also prescribes plenty of natural light in the morning to wake the body up, then working by a window if possible during the day to keep yourself feeling energised.
Actionable takeaways
Keep lights low in the evening.
Expose yourself to plenty of natural light after waking.
Try to work in a well-lit spot, such as near a window.
Similarly to being told to 'sleep more', finding ways to destress is easier said than done. With emails on our phones and more information passing between our ears than ever before, stress is everywhere. But taking steps to reduce it before bed can lead to a deeper sleep.
Journalling, mindfulness, meditation and practising gratitude are all possible options, Dr Bostock says. Even writing a to-do list to establish control and rid yourself of nagging thoughts can be an effective intervention.

Exactly when you were born could play a hidden role in your future BMI
Eating well, exercising regularly and maintaining a clean-living lifestyle are key to keeping your weight healthy but new research suggests a different factor could affect BMI Known as BMI, Body Mass Index is the calculation that uses your height and weight to estimate your body fat. Staying within the right weight range is said to lower your risk for serious conditions such as heart disease, high blood pressure and type 2 diabetes - and the way to do it is typically focused on diet, exercise and lifestyle. Prioritising getting enough sleep and avoiding stress, consuming nutrient-rich foods and engaging in physical activity are thought to be the key to maintaining a healthy BMI. But a new study has found another factor that could come into play - and there's nothing you can do about it. Research published in the journal Nature Metabolism explored the link between weather conditions and a person's physiology over the course of their life and an intriguing result emerged. People conceived during colder months, researchers found, could end up with a lower BMI and less fat around their internal organs, the Independent reported. The study from Japan 's Tohoku University looked at 683 healthy men and women aged between three and 78 and found those conceived during a cold season ended up with 'higher brown adipose tissue density'. Brown fat tissue generates heat to help the body maintain its core temperature, including in newborns and cold environments. Higher density of the tissue has been linked to a lower internal fat accumulation into adulthood, meaning people conceived during a cold season could end up with a lower BMI. By contrast to brown adipose tissue, white adipose tissue is the most abundant type of fat in the body. Research found when it gets colder, less of this is stored than under hotter conditions. "We report that individuals whose mothers conceived during cold seasons exhibit higher brown adipose tissue activity, adaptive thermogenesis, increased daily total energy expenditure and lower body mass index and visceral fat accumulation," said researchers in the study. "Lower outdoor temperatures and greater fluctuations in daily temperatures during the fertilisation period are key determinants of brown adipose tissue activity." they added. Obesity is a key risk factor for death, with more than a billion people around the globe thought to be living with very high levels of body fat. You're considered to be obese if you're 20 per cent over your healthy weight range. Key advice to lower your BMI includes: 1. Do at least five half-hour sessions of moderate activity every week, such as brisk walking. 2. Eat five portions of fruit and veg a day. Besides being low in fat, they contain antioxidants, which help prevent serious illness. 3. Drink no more than two to three units of alcohol per day for women (and a weekly limit of 14). A unit equals half a pint of beer, a small glass of wine or a single measure of spirits. 4. Limit takeaways to once or twice per month. They are full of saturated fat, which raises the risk of high blood pressure and cholesterol - both of which are major risks for heart disease.

Democrats' ‘betrayal' of Joe Biden revealed by his press secretary in new book
Joe Biden's White House press secretary has quit the Democratic Party and written a tell-all memoir about the party's 'betrayal' of the former president. Karine Jean-Pierre, 50, who fiercely defended Mr Biden when reporters asked about his ailing health, has penned a book about her journey to becoming an 'independent' after serving in both Barack Obama and Mr Biden's administrations. Independent: A Look Inside a Broken White House, Outside the Party Lines, which will be released on Oct 21, is described as a 'groundbreaking, revelatory assessment of America's broken two-party system'. According to Legacy Lit, a Hachette Book Group imprint that will publish the book, 'insider' Ms Jean-Pierre will urge Americans to 'embrace life as independents' in a 'country obsessed with blind loyalty'. 'Jean-Pierre didn't come to her decision to be an independent lightly,' it adds. 'She has served two American presidents, Obama and Biden. In 2020, she joined Biden's campaign as a senior adviser, becoming Harris's chief of staff and then, two years later, White House press secretary. She takes us through the three weeks that led to Biden abandoning his bid for a second term and the betrayal by the Democratic Party that led to his decision.' The book is described as a 'hard-hitting yet hopeful critique' in which she encourages Americans to 'think outside of the blue-and-red box'. Jake Tapper, the CNN journalist, has been accused of cashing-in with a book about Mr Biden's decline in office while failing to report on it while he was still in office. Tapper was accused of being a hypocrite following the release of Original Sin, which alleged aides shielded the public from the extent of Mr Biden's decline while serving as president. According to the authors, the president at one stage forgot the name of actor George Clooney and was closely managed by his wife, Jill Biden, who allegedly protected the president from criticism and finished his thoughts for him. Mr Biden, 82, said the allegations were 'wrong' and 'there's nothing to sustain' them. Last month, he revealed he had been diagnosed with an aggressive form of prostate cancer. Ms Jean-Pierre, who was in Mr Biden's inner circle, was criticised at times for being evasive about Mr Biden's physical condition. Her book appears to represent a continuation of her defence of Mr Biden. Earlier this year Ms Jean-Pierre accused the Democratic leadership of attacking Mr Biden like a 'firing squad'. 'Until January 20, I was responsible for speaking on behalf of the president of the United States,' Ms Jean-Pierre, the first black woman and openly gay person to hold the position of White House press secretary, said in a statement released on Wednesday. 'At noon on that day, I became a private citizen who, like all Americans and many of our allies around the world, had to contend with what was to come next for our country. I determined that the danger we face as a country requires freeing ourselves of boxes. We need to be willing to exercise the ability to think creatively and plan strategically.' Ms Jean-Pierre succeeded Jen Psaki as press secretary in 2022 after previously serving as deputy press secretary and also working as a senior adviser during Mr Biden's 2020 campaign. During Mr Obama's first term, she was a regional political director.

Joe Biden's health history amid 'aggressive' cancer diagnosis
Former US President Joe Biden has revealed he has been diagnosed with an "aggressive" form of prostate cancer after a stay in hospital last week. The 82-year-old has grade 5 prostate cancer that has spread to his bones. Biden was admitted to hospital last week for the investigation of a "prostate nodule", news which, at the time, raised few eyebrows as doctors planned to conduct "further evaluation". Now, he is considering the best treatment for his diagnosis. However, it's not the first time the former president has been plagued by illness. Here, we take a look at some of his other health woes. In March 2023, the White House announced that Biden had undergone a procedure to remove a common type of skin cancer from his chest. Dr. Kevin O'Connor, a former U.S. Army physician who treats the 82-year-old, said at a press conference at the time that there had been a biopsy that "confirmed that the small lesion" removed from the then-president "was basal cell carcinoma". "All cancerous tissue was successfully removed. The area around the biopsy site was treated presumptively with electrodessication and curettage at the time of biopsy. No further treatment is required," O'Connor said, as reported by the Independent. Biden battled COVID twice during his term as president, once in 2022 and a second time in July 2024. The latter was just days before he stood down from his re-election bid after a concerning debate against Donald Trump. He also broke his food during his presidency, which happened while playing with one of his German Shepherd dogs. In 1980, Biden had suffered a near-death experience that required him to undergo brain surgery two times within five months. He shared his experience at a Jerusalem hospital during a February 2023 visit to Israel. "I was making a speech and I had a terrible headache — this was years ago — and I did a very stupid thing: I got on an aircraft and I flew home. It turned out I had two cranial aneurysms, and I got rushed to a hospital in the middle of a snowstorm for a nine-and-a-half-hour operation that saved my life," he recalled, describing the February 1988 trip to Walter Reed Army Medical Centre, then in Northwest Washington, DC. He shared how shortly after the speech, he had passed out at the University of Rochester. In his 2007 memoir titled Promises to Keep, he shared how he felt "lightning flashing inside my head, a powerful electrical surge — and then a rip of pain like I'd never felt before". At Walter Reed, he was told he needed surgery, with only a 50-50 chance he'd live through the procedure. "Maybe I should have been frightened at this point, but I felt calm," he wrote. "In fact, I felt becalmed, like I was floating gently in the wide-open sea. It surprised me, but I had no real fear of dying. I'd long since accepted the fact that life's guarantees don't include a fair shake," he added. Biden survived the life-saving surgery, and three months later, he underwent a similar procedure to fix another, smaller aneurysm on the opposite side from the first. A senator at the time of the operation, Biden then made a last-minute request of the surgeon, Dr Neal Kassell, as he was being wheeled in for the procedure. Dr Kassell recalled: "He looked me in the eye and said, 'Doc, do a good job, because someday I'm going to be president."
