Sleeping on your side vs sleeping on your back: Which is better for health?
While back sleeping is often promoted for optimal neck and spine support, side sleeping has been linked to better digestion and may reduce the risk of snoring or acid reflux. But which is actually better for long-term health — and does the 'best' position vary from person to person?
Dr Vikas Mittal, pulmonologist, Wellness Home Clinic and Sleep Center, Delhi, tells indianexpress.com, 'Both side and back sleeping have their own benefits and drawbacks. Side sleeping is the most popular and generally healthiest position for most people. It helps reduce snoring, supports spinal alignment when done with proper pillow support, and is especially good for people with sleep apnea and acid reflux. However, it may cause shoulder or hip pressure and wrinkles on the face over time.'
He continues, 'Back sleeping, on the other hand, keeps the head, neck, and spine in a neutral position and can help reduce pressure on joints. It may also prevent facial wrinkles. However, it can worsen snoring and obstructive sleep apnea in some individuals. It's also not recommended for pregnant women, especially in later stages, as it can reduce blood flow to the baby.'
Dr Mittal says, 'Yes, the side we sleep on can make a difference.' He adds that sleeping on the left side is often recommended for better digestion and acid reflux relief. 'This position allows gravity to help move waste through the colon and keeps stomach acid from rising into the esophagus. It's also believed to be better during pregnancy, as it improves blood flow to the heart and foetus.'
Sleeping on the right side, Dr Mittal states, while still beneficial in some cases, may increase acid reflux and can put slightly more pressure on internal organs like the liver. 'However, some people with heart conditions might feel more comfortable on their right side. Individual comfort and medical conditions should guide the choice.
According to Dr Mittal, sleeping position can significantly affect people with certain conditions. People with sleep apnea are generally advised to avoid back sleeping, as it can worsen airway obstruction. GERD (acid reflux) patients are encouraged to sleep on their left side to minimise symptoms. Pregnant women should also avoid back sleeping in the second and third trimesters. People with chronic shoulder or hip pain may struggle with side sleeping unless they use proper support pillows.
'In all cases, using the right mattress and pillow can make a big difference in comfort and symptom control,' concludes the doctor.

Urologist explains 5 lifestyle changes that help manage overactive bladder (and how to spot your personal triggers)
Frequent urination, urgent need to urinate, and accidental leakage are common signs. If you find yourself rushing to the bathroom more often than usual, especially with sudden urges that are hard to control, you might be dealing with an overactive bladder. It's a condition that affects millions of people, yet many hesitate to talk about it due to embarrassment or the assumption that it's just part of aging. Frequent urination, urgent need to urinate, and accidental leakage are common signs. While medication and medical interventions are available, many people find relief through simple changes in their daily habits. But which changes actually make a difference? asked an expert to help break it down. (Source: Freepik) 2 / 8 Five evidence-backed lifestyle changes that can help manage or reduce overactive bladder symptoms Dr Sreeharsha Harinatha, senior consultant, Urology, Uro-Oncology, Robotic Surgery and Renal Transplant at Kauvery Hospital, says, 'Overactive bladder can significantly affect daily quality of life, but several lifestyle adjustments have been shown to help manage its symptoms effectively.' The first is fluid management. While staying hydrated is important, spreading fluid intake evenly throughout the day and avoiding large amounts before bedtime can reduce urgency and nighttime urination. 3 / 8 The second is limiting bladder irritants such as caffeine, alcohol, carbonated drinks, and artificial sweeteners. These substances can stimulate the bladder and worsen symptoms. (Source: Freepik) 4 / 8 The third is maintaining a healthy body weight. Excess weight increases abdominal pressure and can contribute to bladder control issues. Studies have shown that even moderate weight loss can improve symptoms. (Source: Freepik) 5 / 8 The fourth is bladder training, a behavioural technique that involves gradually increasing the time between urinations to retrain the bladder to hold urine for longer periods. (Source: Freepik) 6 / 8 Finally, incorporating pelvic floor muscle exercises, often known as Kegel exercises, can strengthen the muscles that support bladder control and significantly reduce urgency and leakage episodes when done consistently over time. (Source: Freepik) 7 / 8 How can people with an overactive bladder identify their personal triggers Dr Harinatha says, 'Identifying personal triggers often starts with keeping a bladder diary. This involves noting the timing and amount of fluid intake, the frequency and urgency of urination, and any leakage episodes.' Over a few days or weeks, patterns may emerge that help pinpoint specific triggers, such as certain foods, drinks, stress levels, or activities. He adds, 'For example, if someone consistently experiences increased urgency after drinking coffee or citrus juice, these items may be acting as bladder irritants. Similarly, noticing symptoms worsen on days with high stress or poor sleep may suggest that emotional or physical factors also contribute.' (Source: Freepik) 8 / 8 With this information, Dr Harinatha mentions that individuals 'can begin a process of elimination or modification, adjusting their diet and routines gradually and observing changes in symptoms.' In some cases, working with a healthcare provider or a dietitian can provide additional support in identifying and managing these triggers safely and effectively. (Source: Freepik)

‘No food at all, just water for nine days': Nargis Fakhri's extreme fasting routine for glowing skin sounds tempting, but expert warns it can cause more harm than good
Fasting has become a hot topic in wellness circles — some see it as a tool for mental clarity, others swear by its weight loss benefits. Actor Nargis Fakhri, too, swears by a unique fasting ritual — but with a serious caveat. In a recent interview, she revealed that she goes on an intense water-only fast twice a year, lasting nine days each time. 'I do fasting twice a year, no food at all, just water for nine days. It's very difficult. But once I'm done, I'm telling you, you look snatched. I mean, the jawline is out, the face is glowing. But I wouldn't recommend it,' she told Soha Ali Khan during a chat on Hauterrfly's YouTube channel. While she credited the fast for improving her appearance, she was quick to warn that such extreme practices aren't advisable for everyone. 'Everybody wants a quick fix, but there's no quick fix. It's always a combination of things, and the combination for me seems to be great sleep. I sleep like eight hours a night. I also try to hydrate. Then, also, my food choices. Like, I want foods that are nutritious and have vitamins and minerals in them,' she added. Dr Anjana Kalia, ayurvedic doctor and nutritionist at Diet Clinix, tells 'A nine-day water-only fast is not considered medically safe for the average person. Prolonged fasting without any caloric or nutritional intake can lead to serious physical and mental health risks. These include electrolyte imbalances, dehydration, low blood sugar, muscle loss, dizziness, fatigue, and heart rhythm abnormalities.' She continues, 'The body needs a constant supply of essential nutrients — vitamins, minerals, glucose, and proteins — to function properly. Prolonged fasting can weaken the immune system, impair kidney function, and negatively affect mental clarity and mood. It is perilous for people with diabetes, low blood pressure, or any chronic illness. Fasting beyond 24 to 72 hours should only be done under strict medical supervision.' While it is possible to notice short-term physical changes like a slimmer appearance or glowing skin after a fast, Dr Kalia stresses, these effects are usually temporary. The 'snatched' look often results from water loss and reduced bloating, not actual fat loss or improved health. 'Similarly, clearer skin may be due to reduced intake of processed foods or allergens, but long-term skin health depends more on a balanced diet, hydration, and overall wellness. The glow can quickly fade once normal eating resumes or if the body becomes nutrient-deficient. So while fasting might give a temporary 'clean' look, it is not a reliable or healthy method for beauty or wellness,' states the expert. Dr Kalia suggests that rather than extreme fasting, it's healthier to 'adopt consistent lifestyle habits.' Eat a balanced diet rich in fruits, vegetables, whole grains, lean protein, and healthy fats. Drink plenty of water throughout the day. Avoid excessive sugar, alcohol, and processed foods. Getting 7-8 hours of sleep, managing stress, and including light exercise (like walking or yoga) are also key. For skin health, she adds that foods rich in antioxidants (like berries, nuts, and leafy greens) and omega-3 fats (like flaxseeds or fatty fish) are especially beneficial. These changes are not only safer but also more sustainable and effective in the long run. DISCLAIMER: This article is based on information from the public domain and/or the experts we spoke to.

Indian teen develops Paraspeak, an AI-powered translator for paralysis patients
'My school had taken me for a field trip to a paralysis care centre, and I saw the difficulties the patients had in communicating with their caretakers and their surroundings. That's where the idea came to me. What if there was a machine learning system which could understand what they're saying?' said 11th-grade student Pranet Khetan. The young innovator has developed a small device that can translate slurred speech. The device, according to Khetan, is India's first open-source Automatic Speech Recognition (ASR) framework specially designed for Hindi dysarthric speech. Talking about the device, Khetan said that what struck him most profoundly was dysarthria – a motor speech disorder affecting patients with paralysis, Parkinson's disease, COPD, and other neurological conditions. 'The advantage with dysarthria is that the speech processing in their brain is completely fine. They know what they want to say, and they understand everything everyone else is saying. It's just that their muscles aren't able to properly produce speech. But the meaning and that intent are still there,' Khetan told Khetan has named the device Paraspeak, and it aims to address a critical gap in the field. In India, while there is no specific data on dysarthria, it is a fairly common speech disorder. The teen said that while there is some research for English dysarthric speech recognition, there are no solutions for Hindi-speaking patients. 'I chose Hindi because it's spoken by over 40 per cent of India. But surprisingly, there is no dataset for Hindi dysarthric speech. No one has ever gone out and collected Hindi dysarthric speech for the purposes of training a model,' he explained. This led to one of the challenging aspects of his project – data collection. As part of his research, the teen visited NGOs and care centres and created the first-ever dataset of Hindi dysarthric speech comprising 42 minutes of recordings from 28 patients. Later, with the help of sophisticated data augmentation techniques, he expanded it to 20 hours of synthetic training data. Even a simple sentence with three or four words would take time and effort for those affected by dysarthria. 'It was really emotional, because what happens with dysarthria is that people aren't able to understand what you say. So eventually they withdraw from their surroundings and stop trying to speak in the first place,' he said. 'Many of these patients were putting in a lot of effort, and there were many cases where I was telling them to stop, the doctor was telling them to stop, but they still kept going. They were really happy to contribute.' Following real-time testing, Khetan filed a patent for the device. Khetan shared that the small device is built on the transformer architecture, the technology that is powering large language models like ChatGPT and Claude. However, for the device, he adapted the architecture for speech recognition. When it comes to function, the system takes slow, unclear speech from dysarthric patients and converts it into clear, understandable speech that can be played aloud. The device comes in a compact form factor, as small as a webcam, that can be worn around the neck. 'All this device needs to operate is an internet connection. It has a long battery life. It can last more than 10 hours at least,' Khetan explained. The patient needs to simply press a button to activate recording, speak into the built-in microphone, and the audio is processed by AI models running on cloud servers before returning clear speech output. What makes Paraspeak unique is its scalability. Unlike existing research solutions that work only with individual patients, Paraspeak is designed to work across multiple speakers with the same underlying system. 'Current research is very limited in this area. Such models only work with one patient. So let's say I take one patient's data, and I train my model on them. It will only work with them. It's not scalable across multiple speakers,' he noted. The speech recognition system stands out for its remarkably low cost of construction. Khetan said that the device costs Rs 2,000 to manufacture, with a monthly subscription fee of around Rs 200. The subscription here is internet data packs from telecom providers. According to the teen, the low cost of the device makes it accessible. Talking about the cost efficiency, Khetan admitted that it was achieved through numerous iterations over a year. The first prototype was bulky with many wires attached; however, he progressively miniaturised it using custom printed circuit board designs. 'I have designed my own custom printed circuit boards. It's almost like how a smartphone would work on the inside. Very compact, custom electronics, which I've tried to design to create this as small as possible,' said Khetan, who is a student of Shiv Nadar School, Gurgaon. As of now Paraspeak isn't just a proof of concept; according to Khetan, it is a working solution that has been tested on real patients. 'I tested it on seven patients. I also recorded videos of three of them with a variety of diseases like congenital disorders, paralysis, Parkinson's, and COPD, and they were content with the fact that the device worked for them,' said Khetan, whose innovation also got recognised at the Regeneron International Science and Engineering Fair (ISEF) 2025, held in Ohio, USA. His work was also recognised at India's IRIS National Fair. As of now dysarthria is present in over 75 per cent of Parkinson's patients and mostly all late-stage Amyotrophic Lateral Sclerosis (ALS) patients. Technologies like Paraspeak can bring hope to many. Khetan shared that as of today there is no market-ready solution for this disorder, making it a unique piece of tech. When asked what excites him most about technology, Khetan said, 'I'm really passionate about assistive technology. There's so much in the technology spectrum which can be applied to assistive technology to tangibly improve the lives of so many people across the world. The best solutions are those with a tangible human impact, where you can instantly see a change in someone's life.'
