World Music Day 2025: Know how sound frequencies help regulate emotions and lift your mood
In an interview with HT Lifestyle, Prakriti Poddar, global head of mental health and wellbeing for Roundglass Living, a holistic wellbeing app, unpacked the nuanced relationship between sound frequencies and mood regulation. She also highlighted how India identified the power of music through classical tunes, even before the contemporary advancements of neuroscience, which later led to a deeper understanding of how sound frequencies impact the brain.
Prakriti explained,'Neuroscience explains how sound frequencies regulate stress, calm the nervous system, and support healing. But this is not new wisdom. In India's yogic lineage, practices like Nada Yoga and Raga Chikitsa used sound as a pathway to balance, awareness, and wellbeing, centuries before labs validated what ancient sages intuitively understood. Music supports healing as it reduces cortisol, activates the parasympathetic nervous system, improves emotional regulation, and supports better sleep, focus, and healing. Solfeggio frequencies, brain wave entrainment, mantra resonance, raga structures, and isochronic tones, all designed to support mental clarity, emotional healing, and energy balance. Music helps to bring about emotional intelligence, too."
To decode the fundamentals of this music-mind relationship better, Prakriti shared a detailed guide with us that outlined how different frequencies influence our emotional states, how easily sound can support mood transitions, and, lastly, how music fosters connection not just within ourselves but also with others.

Group music activities like singing kirtans, sharing a playlist, jamming at a karaoke session, or attending a live performance lead to emotional resonance within the group members that transcends language.
This shared rhythm activates oxytocin, deepens trust, and cultivates belonging. In India's Bhakti traditions, the communal experience of music was just as healing as the sound itself. It was never just about listening; it was about belonging.

Is your acne itching? Dermatologist reveals it may be fungal acne, shares how to tell the difference
The monsoon season triggers a lot of skin conditions because of the weather conditions. One of them is fungal acne, which many people mistake for regular acne because of overlapping symptoms like breakouts and redness. In an interview with HT Lifestyle, Dr Amit Bangia, Associate Director- Dermatology at Asian Hospital, shared with HT Lifestyle how to spot the differences between regular and fungal acne. Acne may look alike, but may have different root causes. (Shutterstock) ALSO READ: Struggling with jaw and chin acne? Dermatologist says it could be hormonal, shares 5 ways to treat them Dr Bangia highlighted the concern of growing skin infection cases in monsoon and said, 'During the monsoon, high humidity and dampness create the perfect conditions for rapid growth of microbes like bacteria and fungi. This often results in a rise in skin infections, reflected in the noticeable increase in dermatology outpatient visits across the country during this season.' Distinguishing between regular acne, which may result from skincare missteps or hormonal imbalances, and fungal infection-related flare-ups is important, as it helps guide targeted treatment. What is the difference between fungal and regular acne? Fungal acne has a burning sensation.(Shutterstock) The big difference Dr Bangia revealed when it comes to the cause is that fungal acne is caused by yeast, which is unlike typical acne caused by bacteria. Recognising the causal difference is important as it influences the treatment approach. He said, 'Fungal acne, unlike typical acne, is brought about by an excessive amount of the yeast-like fungi Malassezia. Regular acne results from clogged pores and bacterial proliferation.' Sharing a brief lowdown on the areas where acne typically occurs, he added, 'For the unversed, acne usually arises in areas with a high concentration of oil glands, such as the T-zone (the forehead, nose, and chin). Fungal acne can appear on a variety of body areas, including those with decreased oil production.' Knowing the distinguishing features helps in identifying these two types of acne more accurately. Dr Bangia noted, 'Fungal acne commonly appears as little, itchy lumps on the face that resemble tiny pimples or whiteheads. They can also appear in other body sections like the chest, back, and shoulders. These bumps may be associated with redness and inflammation." "Another noticeable feature is the prevalence of itchy or burning feelings. Fungal acne is often associated with significant itching, but ordinary acne may be less unpleasant,' Dr Bangia shed light on one of the prominent symptoms. Fungal acne is more common in people with compromised immunity, he said, 'such as those with diabetes or HIV, or even patients who use antibiotics regularly, which can lead to an imbalance of bacteria and yeast on the skin.' Treatments Treatments and management strategies differ for both conditions. Dr Bangia noted that if over-the-counter acne treatments and solutions prove ineffective, it may be a case of fungal acne. He said, 'Typical acne can be treated with benzoyl peroxide or salicylic acid, whereas fungal acne requires antifungal medication.' But since prevention is always better and monsoon increases the risk of skin infections, knowing the precautionary methods will keep you a step ahead. Dr Bangia shared, 'First and foremost, people should prioritise personal hygiene, keeping skin dry by choosing breathable cotton and linen fabrics, and using antifungal powders or lotions in vulnerable regions. Bathe with mild antiseptic soaps is are extremely fundamental prophylactic measure.' What are the skincare ingredients consumers use for acne-prone skin? Now, when it comes to regular acne, which is very common, let's take a closer look at the skincare ingredients that skincare enthusiasts are leaning towards. When it comes to managing regular acne, especially among people with sensitive skin, they often incorporate ingredients that help reduce breakouts without irritating the skin. Malini Adapureddy, Founder and CEO of Deconstruct, shared insights on market trends and the key ingredients consumers are embracing for acne-prone skin. She said, 'For sensitive, acne-prone skin, the key isn't just using fewer products—it's about choosing the right ones. This means selecting ingredients that address skin concerns without causing irritation. For instance, consumers choose ingredients like Niacinamide, which can soothe inflammation and regulate oil production, while Alpha Arbutin helps fade dark spots gently over time. When used in the right concentration, even active ingredients like Salicylic Acid can cleanse effectively without stripping the skin."

Beat work burnout with calming ambience: Top design tips to revamp office and home workspace for improved wellness
Workplace stress isn't just a rough phase during the presentation season or appraisal week; it has become an everyday reality of working life with hustle culture working overtime to disguise burnout as passionate, ambitious drive. All this pressure is taking a toll on overall health, making employees more vulnerable to serious health conditions. Workplace, whether at the office or home, should support mental and physical wellbeing by being comfortable.(Shutterstock) ALSO READ: Toxic positivity at work: Experts share why it hurts mental health and suggest strategies to build honest environment In a report released by Plum Insurance, the Plum Employee Health Report revealed significant insights about the working population. As per the report, 70 per cent of Indian employees face moderate to high risks of chronic diseases, significantly higher than their counterparts in developed nations. Moreover, the report also revealed the shocking statistic that only 14 per cent of employees are truly thriving at work, and 29 per cent of employees report feelings of isolation, indicating widespread burnout. Burnout is not a buzzword anymore, but a sad reality for employees. Saurabh Arora, Co-Founder and CTO, Plum Insurance, further weighed in on the findings of the report and shared some strategies for wellness, "Clearly, there is an urgent need for innovative solutions that address not just physical, but also mental and social health dimensions. To tackle this, adopting measures like the '14-hour health week', where employees dedicate two hours daily for comprehensive health and wellness activities, becomes crucial. Hybrid work arrangements or structured Work-from-Office models can significantly alleviate feelings of loneliness and create a conducive environment for nurturing holistic well-being. " Alongside initiatives that address hybrid working formats, the physical environment where you work, whether at the office or at home, also plays a vital role in supporting your well-being. HT Lifestyle reached out to experts to explore how office and home workplaces can be modified for better productivity and wellness. Office workplace designs Offices include breakout rooms where employees step away from their desks for casual meetings (Shutterstock) At office workplaces, whether you are working at your desk or unwinding in a breakout area, the space needs to be attuned to your physical comfort and mental wellbeing. Titir Dey, Global Managing Director, Design at Space Matrix, shared smart design tips with us on creating workplace zones that support both focused work and restorative relaxation: 1. Designing for relaxation Effective breakout spaces are not monolithic; they are dynamic 'Multi-Modal Hubs' that acknowledge the full spectrum of human work. By strategically combining diverse spatial elements, a low-slung sofa inviting quiet reflection, high tables sparking animated informal discussions, or writable surfaces beckoning impromptu ideation, organisations can truly cater to cognitive diversity. Visual segmentation, achieved through artful layering of lighting, subtle ceiling treatments, or defining area rugs, carves out distinct zones without imposing physical barriers. Rather than a tucked-away afterthought in isolated corners, where even the most thoughtfully designed spaces wither from disuse, integrate them seamlessly into the office layout. Placing these areas adjacent to workstations or high-traffic corridors enables a natural behavioural flow mapping, encouraging organic, spontaneous use throughout the day. 2. Designing for work Sound-absorbing materials and layered acoustic strategies work in concert to manage cognitive load, preserving a quiet hum of privacy even in bustling open layouts. Ergonomic seating, adaptable lighting schemes, and, where possible, natural ventilation all contribute to a healthier, more genuinely inviting environment. Home workplace design Home workplace designs become more personal, reflecting personality.(Shutterstock) Your home workspace, especially on remote working days, needs to be fine-tuned as well to ensure comfort, productivity, and mental clarity. With work increasingly taking a hybrid form, and even otherwise, the space where you work at home too deserves meaningful design attention. A well-designed home office can uplift your mood, reduce stress, and support overall wellness, helping you work with greater focus and ease. Rajat Kumar, Founder and Principal Architect at Recro Kaerdo, shared with HT Lifestyle one of the rising trends in home workspaces: the return of mid-century design. He said, 'Originating from design philosophies of the 1950s and 60s, this stylistic thought is not just about looking good; it is about creating a space that meets your needs, emotionally and practically.' Rajat recommended these essential tips for creating a good workspace that addresses all your needs, from storage needs to mood regulation, with a touch of vintage design: 1. Opt for clean lines and classic wood finishes Select desks with simplicity in walnut, teak, or oak. Pair with moulded wood or faux-leather chairs Less bulky storage options, like floating shelves or minimal credenzas, are preferred 2. Add texture for tactile experience Unlike cold and minimalist work setups, mid-century design works extensively with texture to keep the senses in balance. Have boucle or jute rugs underfoot Use upholstered chairs in tweed, velvet, or wool Install cork boards, woven baskets, or matte ceramic containers 3. Add plants Plants add softness, colour, fresh air, and organic contrast to clean looks, so place them near windows or just near the backdrop of your desk. A plant enhances your focus, brightens your mood, and ties together the entire space with a binder touch of nature. Choose low-maintenance, low-light plants like snake plants, rubber plants, or pothos Allow light with sheer curtains or light-filtering blinds. 4. Vintage mood lighting In mid-century modern design, lighting is sculptural and practical at once. It builds ambience and creates the atmosphere for focused work. Pick a brass dome lamp, or go for an enamel desk light with a gooseneck. Pendant lights or arc floor lamps can bring in visual drama. Keep those LED bulbs warm (2700K–3000K) for that soft opening embrace.

Oncologist shares surprising causes of head and neck cancer in non-smokers: 'It's not just tobacco anymore'
Head and Neck Cancer Day, observed annually on July 27, was established by the International Federation of Head and Neck Oncology Societies to raise awareness about these often-overlooked cancers. While tobacco use was once considered the primary culprit, head and neck cancers are increasingly affecting non-smokers as well, bringing newer risk factors like HPV, poor oral hygiene, and pollution into the spotlight. (Also read: Gastroenterologist shares 4 bowel cancer symptoms to look out for: Persistent bloating to night sweats ) Long-term exposure to pollution, chemicals, and poor diet increases head and neck cancer risks, especially in non-smokers.(Freepik) "Head and neck cancers have had a long history of association with alcohol and tobacco consumption. However, over the past few years, there has been a distinct trend in the patient population being diagnosed. More and more patients with no smoking history are now presenting with these cancers. This trend indicates that evolving factors beyond conventional causes are at play," says Dr Prashant Pawar, consultant – head and neck surgical oncology, HCG ICS Khubchandani Cancer Centre Cooperage, Colaba. Dr Prashant further shared with HT Lifestyle the surprising causes behind this shift and what you need to watch out for. Development of HPV related cancers The human papillomavirus: It is claimed that HPV-16 is associated with oral cancers, oropharynx cancer, which is located at the base of the tongue and the tonsils, and is very common among young non-smokers. The patients affected with HPV-positive head and neck cancer are younger, healthier, have urban backgrounds, and have better access to and awareness of health care. Their therapy response and disease pathophysiology differ from the tobacco-induced ones. Emerging risks for head and neck cancer include air pollution and HPV, impacting non-smokers more frequently. (Freepik) Environmental and occupational exposure The newer risks are long-term exposure to air pollution, industrial chemicals, and contaminated oral health, which are seen especially in the urban and semi-urban areas. An increased risk can also come with poor diet, chronic acid reflux (GERD), and a weakened immune system, even in non-smokers. Slow time of diagnosis in non-ex-smoking patients Since head and neck cancer is more related to the smoking rate, non-smoking patients will ignore the initial symptoms, which may include frequent sore throat, hoarseness of voice, or a lump in the neck area, thus delaying the time of diagnosis. Importance of awareness and immunisation HPV immunisation for teenagers (male and female) is key in reducing the probability of getting head and neck cancers in the future. Personalised treatment approaches Cancers that are HPV positive are easier to treat and have a more favourable prognosis. Still, proper diagnosis and staging remain relevant to the best outcomes.
