What Is Cognitive Shuffling?
Dr. Joe Whittington, 47, has been an emergency room physician for two decades, but he can still find it tough to quiet his mind after leaving the hospital.
As he tried to doze off after one particularly chaotic shift, he kept thinking about a victim of a motorcycle crash whose vital signs had tanked, a patient who developed sepsis and another whose heart had suddenly stopped beating.
His tendency to replay the night's events — and his irregular work hours — often made it tricky for him to fall asleep. Over the years, he tried deep breathing, meditation and melatonin, before finally stumbling upon a technique called cognitive shuffling.
The sleep strategy helps to 'force my mind out of that loop and into a state where I can finally rest,' said Dr. Whittington, who has shared it on his Instagram account, which has more than 750,000 followers.
'Cognitive shuffling' has been touted on social media for years, but does it really work? We spoke with sleep experts and the scientist who created the technique to learn more.
Cognitive shuffling is a mental exercise that involves focusing your mind on words that have no association with one another, as a way of signaling to your brain that it's time to fall asleep. The task is meant to be engaging enough to distract you from the thoughts that may be preventing you from falling asleep, but not so interesting that your brain perks up.

The potential benefits of the ‘Japanese walking' workout which fans claim is better than 10,000 steps a day
There have been numerous walking workout trends that have circled social media in recent years. It's no wonder—walking has numerous benefits, including reducing heart disease risk, strengthening your joints and heart, boosting your mood, and potentially helping you live longer. The latest trend making the rounds across TikTok and Instagram is known as 'Japanese walking,' and one creator claims that in just 30 minutes, you'll get 10 times the benefits of hitting 10,000 steps a day. The workout originates from a 2007 study based in Japan where 246 participants were divided into three groups: no walking, moderate-intensity continuous walking (walking at a moderate effort and taking at least 8,000 steps per day four or more days per week), and high-intensity interval walking. The third group, doing the high-intensity intervals, were instructed to walk slowly for three minutes, then walk quickly at a hard effort for three minutes, and repeat five or more times for four or more days per week. The researchers discovered that this group experienced noticeable improvements in strength, endurance, and decreased blood pressure, more so than the moderate-intensity continuous walking group. This workout is what's now become known as 'Japanese walking.' Another study from 2018 observed participants who did this exact walking workout over the course of 10 years. They found that those who kept up with the workout for the duration of the study experienced a 20% improvement in their leg strength, and a 40% improvement in their peak exercise capacity. The researchers concluded that those participants had protected against age-associated declines in physical fitness. Even those who weren't able to maintain the workout for the full 10 years had those improvements partially preserved. Since you're getting your heart rate up during the harder walking intervals, your body gets the benefit of more moderate-to-vigorous intensity exercise. The Centers for Disease Control and Prevention recommends 150 minutes of moderate-intensity activity each week for most adults, or 75 minutes of vigorous-intensity activity—and pushing the walking pace every so often could help you reach that target. Additionally, research shows that moderate-to-vigorous intensity activity is associated with lower risk of early mortality and improved cardiorespiratory fitness. For the higher-intensity intervals, your heart rate should be elevated to the point where you're just starting to feel out of breath, but not at your maximum effort. The researchers consider this 70% of your max effort capability. Meanwhile, the lower-intensity walking should be an easy effort, where talking is still comfortable. Alternate walking at each intensity for three minutes until you reach 30 minutes. Incorporate this workout in your routine four times per week. For more on walking: Walking is a super exercise. The truth about the number of steps you really need, and maximizing the benefits Walking faster may help you live longer. Experts say to aim for this pace Walking more could add as much as 11 years to your life, study says. Here's how This story was originally featured on

NHS set for boost of up to £30bn as other budgets feel squeeze
The NHS is expected to receive a funding boost of up to £30 billion in the spending review next week at the expense of other public services. The Department of Health is set to be handed a 2.8% annual increase in its day-to-day budget over a three-year period. The cash injection, which amounts to a rise of about £30 billion by 2028, or £17 billion in real terms, will see other areas including police and councils squeezed, The Times newspaper reported. Sir Keir Starmer has pledged to ensure that by the next election 92% of patients in England waiting for planned treatment are seen within 18 weeks of being referred. Latest NHS data suggests around 60% of people are currently seen in this time and figures released last month showed the overall number of patients on waiting lists had risen slightly from 6.24 million to 6.25 million. Chancellor Rachel Reeves has acknowledged that she had been forced to turn down requests for funding in a sign of the behind-the-scenes wrangling over her spending review. She insisted the blame for the tight economic situation lay with the Conservatives rather than her rigid rules on borrowing and spending. The Chancellor said despite a £190 billion increase in funding over the spending review period 'not every department will get everything that they want next week and I have had to say no to things that I want to do too'. On top of the increase in day-to-day spending, funded in part by the tax hikes Ms Reeves set out in her budget, looser borrowing rules will help support a £113 billion investment package. Economists have warned the Chancellor faces 'unavoidably' tough choices when she sets out departmental spending plans on June 11. The Institute for Fiscal Studies (IFS) think tank said defence and the NHS will dominate the review, raising the prospect of cuts to other unprotected departments.
