Struggling to sleep? Turn to THIS Yoga technique
A study reveals that Yoga Nidra enhances sleep and brain function. Practicing this yoga technique for 20 minutes daily improves sleep quality. It also boosts memory and cognitive performance. Participants experienced increased delta-wave activity during deep sleep. They also showed faster responses in cognitive tests. Yoga Nidra improves focus and learning abilities.
In this modern time and age, sleep has become a luxury. Amidst the whole rat race, people tend to put sleep on the back burner. Sleep deprivation is linked to an increased risk of chronic health problems like heart disease, high blood pressure, diabetes, and obesity, among others.
But what if a simple technique could solve the problem? Yes, a guided yoga practice could not only improve sleep quality but also enhance memory and cognitive performance.
According to a pilot study published in the journal
PLOS ONE
, just two weeks of practicing a certain yoga technique for 20 minutes a day was linked to deeper sleep and better brain function.
Yoga nidra, aka yogic sleep, is a kind of mindfulness training that shows promise in improving sleep, cognition, learning, and memory.
It is a relaxation technique that is part of the yogic tradition, specifically a form of tantric relaxation. It is a guided practice that induces a deep state of conscious relaxation. One can lie down and practise this technique. The goal is to move into a deep state of conscious awareness sleep, which is a deeper state of relaxation with awareness.
One could experience the transition through stages of wakefulness, dreaming, and deep rest.
A study led by Karuna Datta of the Armed Forces Medical College in India looked into the effects of yoga nidra on sleep. Using objective tools such as polysomnography to measure changes in
sleep patterns
, the participants were guided through yoga nidra using a pre-recorded 20-minute audio session each day. After two weeks, results showed a significant increase in delta-wave activity during deep sleep, a key indicator of restorative rest.
Distinct from other active forms of yoga, which focus on physical postures, breathing, and muscle control, yoga nidra guides people into a state of conscious relaxation while they are lying down. This technique is also reported to improve sleep and cognitive ability.

The polysomnography measures brain activity to determine how long each sleep stage lasts and how frequently each stage occurs. After two weeks of yoga nidra, the researchers observed that participants experienced significantly increased sleep efficiency and percentage of delta-waves in deep sleep.
Interestingly, the participants also had faster responses in all cognitive tests with no loss in accuracy and faster and more accurate responses in tasks including tests of working memory, abstraction, fear and anger recognition, and spatial learning and memory tasks.
All these add to the previous studies that linked delta-wave sleep to improved sleep quality as well as better attention and memory.

Wish to age gracefully? Your midlife might be the last call to shape a healthier future, new research warns
Aging might be inevitable, but how you age could be entirely in your hands. A new wave of research from top global institutions reveals that the secret to a healthier, more resilient older self may lie in the choices you make during your forties and fifties—particularly when it comes to diet, weight, and lifestyle. According to a report on Vice , scientists from Finland's University of Helsinki and University of Turku, along with University College London, have found that shedding excess weight in midlife—without relying on surgery or medication—can drastically reduce the risk of chronic illness later in life. Their study, based on over 23,000 people, suggests that simply returning to a healthy weight can offer long-term health rewards, extending far beyond just staving off diabetes. The Carb Code: Good vs. Bad in Midlife It's not just about losing weight—it's about eating smart. According to parallel research from Tufts University and Harvard University, the kind of carbohydrates you consume in your middle years can greatly influence your chances of aging well. Their study, which followed more than 47,000 women, draws a clear line between the 'good carbs' that promote healthy aging and the 'bad carbs' that sabotage it. by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like Many Are Watching Tariffs - Few Are Watching What Nvidia Just Launched Seeking Alpha Read Now Undo Diets rich in high-quality carbohydrates from whole grains, fruits, vegetables, legumes, and dietary fiber were linked to a significantly higher likelihood—between 6 and 37 percent—of aging healthily. These benefits extended across both physical and mental health domains. On the flip side, midlife diets packed with refined carbs, added sugars, and processed grains were associated with a 13 percent lower chance of maintaining health and vitality in older age. iStock Diets rich in high-quality carbohydrates from whole grains, fruits, vegetables, legumes, and dietary fiber were linked to a significantly higher likelihood of aging healthily. (Representational image: iStock) Midlife: The Make-or-Break Decade for Your Body's Future 'We've all heard that different carbohydrates can affect health differently,' said Andres Ardisson Korat of Tufts. 'But rather than just look at the immediate effects of these macronutrients, we wanted to understand what they might mean for good health 30 years later.' MORE STORIES FOR YOU ✕ « Back to recommendation stories I don't want to see these stories because They are not relevant to me They disrupt the reading flow Others SUBMIT Harvard's Qi Sun reinforced that the findings strengthen existing evidence: fruits, vegetables, legumes, and whole grains aren't just good for now—they're building blocks for a physically and cognitively strong future. In other words, midlife might not just be the midpoint—it could be the last chance to turn your future health around. So if you're in your 40s or 50s and aiming to age without regret, it's time to rethink that plate. Your 70-year-old self will thank you.

6 symptoms of vitamin E deficiency that are not commonly known
Vitamin E, the name sounds familiar, but it slips into the background when compared to more talked-about nutrients like iron, calcium, or vitamin D. Known mostly for its antioxidant powers, vitamin E does a lot more than just help the skin glow or boost immunity. In fact, when the body doesn't get enough of it, it starts to whisper certain signs, not the usual dry skin or weak immunity, but ones that are rarely associated with this silent protector. These symptoms are often brushed aside, misread, or even wrongly treated. It's not about fear — it's about awareness. Sometimes, understanding what's missing in the diet can unlock the mystery behind years of unexplained discomfort. Unsteady movements, especially on smooth floors When vitamin E levels drop, it starts affecting the cerebellum — the part of the brain that controls motor skills and balance. This isn't instant. Over time, a person may start noticing subtle changes in how they walk or how often they lose their footing, especially in slippery areas or when turning quickly. It's not clumsiness — it's a nervous system signal. Strange tingling or prickling in the hands and feet Vitamin E plays a crucial role in protecting nerve endings. Without enough of it, nerves start losing their insulation, much like electric wires with worn-out covers. by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like Perdagangkan CFD Emas dengan Broker Tepercaya IC Markets Mendaftar Undo The result? Odd sensations like pins and needles, numbness, or even burning feelings in the limbs — especially during rest or at night. Subtle changes in vision clarity A deficiency in vitamin E can damage the light-sensing cells in the retina over time. This doesn't lead to complete blindness but can cause minor vision disruptions — such as struggling to see clearly in dim light or difficulty adjusting when moving between light and dark areas. These signs are slow and subtle but shouldn't be ignored. Image - iStock Constant fatigue without a medical explanation Vitamin E helps maintain healthy red blood cells. When it's in short supply, oxygen transport may be slightly compromised, making muscles and tissues feel tired without doing much. The body keeps asking for rest, not because it's lazy, but because it's running on half its fuel. Cracked or dry lips despite hydration While dry lips are mostly linked to dehydration or weather, consistent cracking despite drinking enough water could be a hint of vitamin E shortage. This vitamin helps maintain cell integrity. When it's missing, even the soft tissues like lips start losing moisture protection. It's a skin message, loud and clear. 7 Most common signs of Vitamin C deficiency Difficulty recovering from small wounds or muscle injuries Vitamin E plays a key role in reducing oxidative stress and promoting tissue repair. When wounds, even minor cuts or muscle soreness from basic activities, take longer to heal than usual, it could point to a lack of this essential nutrient. The delay isn't just external — internally, healing is sluggish too. One step to a healthier you—join Times Health+ Yoga and feel the change

Trying to lose weight? Expert says changing this morning habit can make a big difference
You've tried it all—intermittent fasting, portion control, protein-rich breakfasts, and even going keto. But what if the key to unlocking your weight loss success isn't about what you eat , but what you drink —or don't? According to Professor Franklin Joseph , head of Dr Frank's Weight Loss Clinic , a common and often overlooked morning mistake is quietly derailing thousands of people from reaching their health goals. The culprit? Ignoring hydration. The Morning Mistake That's Slowing You Down In a recent interview with The Sun , Professor Joseph sounded the alarm on a widespread habit: heading straight for coffee or breakfast without drinking water first. 'Most people wake up and go straight to the kitchen or grab a coffee without a second thought,' he said. 'But if you're not preparing your body for the day properly, you're missing a huge opportunity to boost fat burning, improve energy, and control your appetite naturally.' by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like Canada is looking for skilled immigrants - New job opportunities are waiting for you! Canada Immigration Express Apply Now Undo The body, he explained, loses water overnight through breathing and sweating. Skipping hydration in the morning places you in a state of mild dehydration from the moment you start your day. This seemingly small oversight can snowball into a sluggish metabolism, increased sugar cravings, and brain fog. Water First, Food or Coffee Later The fix? Simple, but crucial. Joseph recommends drinking at least 400 to 500ml of water within 30 minutes of waking up. It's not about sipping slowly either—this early hydration helps reset your internal systems, energizes your cells, and helps regulate hunger throughout the day.

'Electrolytes can make a big difference,' he said. 'They support hydration at a cellular level, helping you feel sharper and more energized—especially if you wake up feeling groggy or are physically active.' iStock Dr. Joseph recommends drinking at least 400 to 500ml of water within 30 minutes of waking up. (Representational image: iStock) Your Coffee Might Be Working Against You And while a cup of coffee may seem like your go-to wake-up call, Professor Joseph offers a strong word of caution. 'Caffeine first thing in the morning spikes cortisol levels—the body's main stress hormone—which can interfere with fat loss, increase belly fat storage, and make you feel more anxious.' That doesn't mean you have to quit coffee entirely—but it may be wise to delay it by an hour or two. Hydrating first allows your body to stabilize and start the day on the right metabolic track. Rewire Your Morning, Reclaim Your Goals In the crowded world of weight loss advice, this insight cuts through the noise with refreshing clarity. You don't need a trendy diet plan or a 5 a.m. bootcamp to make meaningful progress—just a commitment to treating hydration as the first step of your day.
