CBT-I works for '70% of patients' — the Headspace Sleep Advisor on therapy for insomnia
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."

Purespring Therapeutics receives UK CTA approval for Phase I/II clinical trial of PS-002 in patients with primary IgA nephropathy (IgAN)
First patient in Phase I/II clinical trial expected to be enrolled in Q4 2025 UK Clinical Trial Application (CTA) approval shortly follows U.S. IND clearance and granting of European Medicine Agency (EMA) orphan drug designation, enabling readiness for initiation across sites in both the U.S. and Europe PS-002, Purespring's lead precision nephrology programme, targets the complement pathway known to be a driver of IgA nephropathy and is supported by a wealth of preclinical data London – 5 August 2025 - Purespring Therapeutics, a precision nephrology company focused on transforming the treatment of kidney diseases, today announces that its UK Clinical Trial Application (CTA) for a planned Phase I/II study of PS-002, Purespring's lead programme, in patients with IgA nephropathy (IgAN) has been approved by the UK Medicines and Healthcare products Regulatory Agency (MHRA), the NHS Health Research Authority (HRA) and Research Ethics Committee (REC). 'The CTA approval for our Phase I/II clinical trial of PS-002 represents another key milestone as we complete our transition to a clinical-stage precision nephrology company,' said Haseeb Ahmad, Purespring's Chief Executive Officer. 'Building on the recent FDA IND clearance and EMA orphan drug designation, this further validates the potential of our podocyte-targeting approach to go beyond symptom management and directly target kidney disease at its source. Looking ahead, we are committed to working closely with regulators and sites across the U.S. and Europe with the view to expand the therapeutic options available for people living with IgAN.' PS-002 was developed to target the underlying cause of many kidney diseases by modulating complement activation in the kidney via precision targeting of podocytes. The programme is initially focused on the treatment of IgA nephropathy (IgAN), a rare and chronic autoimmune kidney disease that primarily affects young adults. In IgAN, aberrant immunoglobin A (IgA) protein becomes trapped in the kidney's filters, known as the glomeruli, causing complement activation, inflammation, damage and scarring. A significant proportion of affected patients will go on to develop kidney failure despite currently available therapies. The Phase I/II clinical trial, which is expected to enroll its first patient in Q4 2025, will evaluate local administration of PS-002 to treat IgAN. In the Phase 1 part of the Phase I/II study, the main read-outs will be safety parameters, which, together with efficacy biomarkers, will be leveraged to select a dose for the Phase 2 part of the study. This second phase will be used to further define the safety profile and provide early markers of efficacy. Enabled by this latest regulatory approval and the recent U.S. IND clearance, as announced in July 2025, the Phase I/II study will recruit patients across the U.S. and Europe.

Who needs running? These 5 compound exercises burn fat and build muscle after 50
When you buy through links on our articles, Future and its syndication partners may earn a commission. When we reach our fifties, sarcopenia, or the loss of muscle mass, begins to accelerate, which can also impact the metabolism. Therefore, finding an exercise program that can help you burn fat and build muscle is crucial if you want to stay in shape and prevent injuries as you age. A recent study found that lifting weights can help you expend energy and burn fat as effectively as cardio can. Because resistance training also builds strength and muscle, it's an efficient and effective way to burn calories, prevent muscle decline, and keep your metabolism ticking along nicely at any age, but particularly in those later years. As a personal trainer, I work with many clients at various stages of their lives, including my dad, who is 72, and who trains with me twice a week. Here are my favorite five compound exercises (multi-muscle movements) to keep you strong and mobile after 50, and my pa still swears by them in his 70s. Why does lifting weights matter? Lifting weights has tons of benefits at any age, helping you build stronger bones, muscles, and joints, and stay active. Lean muscle mass is more metabolically active than fat, and as muscle mass and metabolism begin to decline naturally after 30, increasing or maintaining muscle mass will help prevent injuries and boost your metabolism. In turn, this can prevent unwanted weight gain and fat accumulation. In other words, it's not all doom and gloom — you can still be extremely fit and healthy at any age, but burning fat may take a little more work, so I also recommend a balanced diet high in protein and plenty of daily movement. And no, that doesn't mean increasing cardio, either; lifting weights can be just as effective, or combining the two. Remember, fat loss doesn't happen in one place only, so be wary of any trainer who tells you that an exercise can burn belly fat. This is called spot-reduction, and it's a myth. Focus on fat loss as a whole by staying active and expending more energy in a day than you consume. 5 compound exercises to burn fat after 50 You could create a circuit of the movements below or incorporate them into a strength routine that mixes in other movements. Remember, every three to four weeks, try to incrementally increase volume in some way — adding weight, for example. This is known as progressive overload, and should prevent your efforts from plateauing. Aim for 3 to 4 sets of 6-12 reps. 1. Squat Stand with your feet roughly shoulder-width apart Bend at the knees and send your hips back as if sitting in a chair behind you Lower into a squat, keeping your chest lifted and back straight — no hunching When your thighs are roughly parallel to the floor, press through your heels and stand, squeezing your butt. You can start with your hands on your hips or arms extended in front of you. If you'd like to add weight, start by holding a dumbbell (or similar) in both hands at your chest. Here's how to squat in more detail. If you're new to squats, placing a chair behind you can be helpful to begin with. 2. Deadlift Stand with your feet hip-width apart and grip a dumbbell in each hand Softly bend your knees and then maintain this fixed position Send your butt back and hinge forward at the hips, lowering the dumbbells down your legs while keeping the weights close to your body Pause as the weights reach roughly shin-level Keep your back straight, chest lifted and shoulders pulled back and down Reverse the movement to stand and squeeze your glutes. Deadlifts are quite technical when you get to the finer details of the movements, so I recommend checking out our guide on how to deadlift properly. 3. Push-up Start in a high plank position with your hands stacked beneath your shoulders and your hips aligned with your shoulders Engage your core muscles, gently pulling your belly in towards your spine Bend your elbows and lower your chest toward the floor, keeping your body straight Pause, then push back up and straighten your arms. If you prefer, use your knees to begin with. Once these feel comfortable, check out some of the best push-up variations. 4. Row Stand with your feet hip-width apart, holding a dumbbell in each hand by your sides Softly bend your knees, then hinge forward at your hips and send your butt back Stop when your chest is almost parallel to the floor Keep your back straight and core engaged Pull the dumbbells toward your hips, keeping both elbows close to your ribcage Pause, then lower them with control. Learn how to do a bent-over row, plus more variations. 5. Bench press Lie on your back on a workout bench with both feet flat on the ground or the bench Engage your core Grip a dumbbell in each hand and extend the weights overhead in line with your shoulders Lower the weights toward your chest, maintaining a 45-degree angle with your elbows Pause at the bottom, then press the weights overhead and extend both arms. Here's how to bench press in more detail. Follow Tom's Guide on Google News to get our up-to-date news, how-tos, and reviews in your feeds. Make sure to click the Follow button.

Transform your body in 15 minutes — the 5 kettlebell moves you need, according to a coach
When you buy through links on our articles, Future and its syndication partners may earn a commission. If you're searching for an accessible piece of fit kit to help inject some fun (and fire) into your at-home weight training, then it's time to invest in one of the best kettlebells. From swings and tactical cleans to deadlifts and snatches, there's a seemingly endless list of exercises to master with this uniquely shaped weight. And doing so comes with multiple benefits. Along with offering a space-efficient way to improve strength, endurance, and overall fitness from home, kettlebells can help to engage multiple muscle groups at the same time, while giving your balance a boost too. If that sounds like your kind of training, grab your humble bell and try out this quick 15-minute workout from NASM-certified personal trainer Jeff Sutherland. Using just one weight, Sutherland has created a speedy full-body workout that is bound to get your heart rate up and put your muscles through their paces. Watch how to do Jeff Sutherland's full body kettlebell workout To make this workout as speedy and effective as possible, Sutherland's session is made up of a single kettlebell complex, which includes five exercises and five rounds. 'In a kettlebell complex, there's no rest in between the exercises; it just seamlessly goes from one exercise to the next,' Sutherland explains. This means you'll complete each of the five exercises back to back before enjoying a one to two-minute break. Once you've done so, you'll need to repeat each exercise for four more rounds. But that said, Sutherland flags that if you do need to rest in between each exercise, you could turn this workout into a circuit with 15-30 seconds in between the next move to help you catch your breath. Either way, the exercises included in Sutherland's session include: Step back kettlebell swing x 10 Figure eight to press x 10 Tactical clean x 10 Clean to squat x 10 Push-ups x 10 Sutherland uses an 18kg kettlebell for each of the first four moves and push-up bars to complete the push-ups, but the trainer notes that if you don't have the latter to hand, this isn't a problem. 'I did five total rounds in under 15 minutes,' he adds. 'Do workouts like this consistently, and you'll get stronger, leaner, and more conditioned.' Can you get in shape with a kettlebell? It's well worth learning how to hold a kettlebell properly before you begin working out with these free weights, as you'll need to perfect different grips for different exercises. But no matter how you look at it, using a free weight like a kettlebell comes with many science-backed benefits. According to a research study produced by the American Council on Exercise, kettlebell training can 'significantly boost' aerobic capacity, while also improving core strength and dynamic balance. A second 2024 research article states that kettlebell training is also a priceless asset in any athlete's workout arsenal, as it can be a 'flexible and useful strategy' for improving players' performance in a variety of sports. Researchers confirmed that dialing up the resistance with a kettlebell can enhance strength, power, endurance, explosive power, and balance.
