Dr Chaitanya Challa is a Hyderabad-based physician specialising in Internal Medicine and Critical Care, with a focus on preventive healthcare and lifestyle-related disorders. He believes good health starts with everyday choices, including the ones men tend to overlook or get wrong. Here, he breaks down common hygiene mistakes, persistent myths and the essentials of a practical daily routine. Does sweating actually cause body odour, and what’s the risk of staying in sweaty clothes for too long?One of the most common mistakes is assuming that sweating itself causes body odour. Sweat is largely odourless; the smell develops when bacteria on the skin break down components of sweat. Areas like the underarms and groin are particularly prone to this. Staying in sweaty clothes for too long, especially after exercise, creates a warm, moist environment that encourages skin irritation and fungal infections. Men should change out of sweaty clothing, dry themselves thoroughly after bathing, and pay attention to areas where moisture accumulates. What should a basic daily grooming routine look like, including underarm and oral care?It doesn’t have to be complicated or expensive. Consistency matters far more than the number of products you use. Bathe regularly, paying attention to the underarms, groin, feet and other areas that accumulate sweat. Use a gentle cleanser, rinse thoroughly and dry properly, particularly between the toes and in skin folds. Change your underwear and socks daily, and change out of damp clothing after exercise. Underarm care also depends on choosing the right products. An antiperspirant helps reduce sweating, while a deodorant primarily controls odour. Choose what suits your needs and skin, and avoid applying fragranced products to irritated or freshly shaved skin. Oral hygiene deserves equal attention. Brush twice daily with fluoride toothpaste, clean between your teeth using floss or an interdental cleaner, and keep up with

Luke Coutinho didn’t set out to become one of India’s most recognised voices in holistic health. He spent a decade at IBM, chasing a conventional corporate career, before a quiet realisation changed everything: the most successful people he knew, with access to the best doctors and trainers money could buy, still weren’t healthy. That gap between excellent medical care and the way people actually live became his life’s work. Fifteen years, a team of over 160, and thousands of patients later, his philosophy of Foundational Medicine and Lifestyle has become essential reading for anyone trying to understand why effort alone doesn’t always translate to health. His Journey From Goa to the corporate world I grew up in Goa in the late 90s and early 2000s. Like most young people, I went through different phases, and I think that’s how it should be. Each chapter teaches you something and leads you to the next. During college, I worked weekends at my cousin’s restaurant, waiting tables, helping in the kitchen and sometimes running the bar. It was hard work, but it taught me a lot about people and service. After college, I worked in hospitality before joining a multinational company that took me to Dubai, London and Qatar. When I returned to India, I spent 10 years at IBM. Throughout those years, nutrition remained a personal interest. I studied it out of curiosity, never imagining it would eventually become my career. The realisation that changed my approach to health My turning point came from what I saw in the corporate world. Many senior executives, people with impressive titles who travelled constantly, were neglecting their health. They had access to the best doctors, nutritionists, trainers and gyms. They could afford any superfood they wanted. And still, they weren’t healthy. That didn’t add up

Based in Bangalore, Dr. Rebecca Pinto is a physiotherapist by qualification, but as she says, “My life has been shaped far more by experience than by textbooks.” Losing her mother at a young age, Rebecca grew up in a single-parent household with her father. Financial constraints were not abstract concepts; they were lived realities. “I saw what a lack of money really does, not just to your lifestyle, but to your peace, your choices, even your relationships,” she shares. That early exposure instilled two beliefs: financial independence creates freedom, but happiness remains a choice. Known among friends as vibrant and dependable, she describes herself as “caring, witty, and observant.” Her critics may call her detached, but she believes that detachment “has helped me survive more than anything else.” Health Beyond Information Today, Dr. Pinto wears multiple hats: physiotherapist, nutritionist, and content creator. But her mission extends beyond treatment plans. She challenges deeply ingrained habits. “When you understand health, you don’t just treat people, you change how they live,” she explains. Content creation began casually, a simple experiment. But the moment people began telling her, “This helped me,” the weight shifted. “That’s when it stopped being content and became responsibility.” For Rebecca, health isn’t about longevity alone. “It’s about living without constantly feeling tired, inflamed, or uncomfortable, which unfortunately has become normal.” Clarity Over Comfort In an industry flooded with trends, her voice stands out for its directness. “Most people don’t change because they lack information. They don’t change because no one has made them question their habits.” She positions herself deliberately between comfort and awareness. Her approach is simple, sometimes blunt, but always rooted in science. “If something is harming you, I’ll say it, even if it’s something you enjoy.” Her audience associates her with two defining qualities: clarity and

Dr Ritika Sinha was born and raised in Gaya, Bihar, and is now based in Bangalore. She comes from a family of doctors, her mother a gynaecologist and her father a surgeon, who runs a hospital in Bihar. Growing up in a medical household meant early exposure to patient care, long hours, and the operational realities of healthcare delivery. “Healthcare was never abstract for me,” she reflects. “I saw firsthand what responsibility toward patients actually looks like.” A major turning point came during the COVID-19 pandemic, when she helped launch a pilot initiative to support patients across India. That experience exposed significant gaps in access and continuity of care, particularly in mental health. “It really opened my eyes to how broken the system can be,” she says. “It changed how I saw my role as a doctor.” In a bold move, she decided to step away from the traditional clinical path just before her postgraduate entrance exams to build Rocket Health full-time. “It was scary,” she admits, “but I had absolute clarity.” Normalising Mental Healthcare Dr Sinha is a doctor-turned-entrepreneur and co-founder of Rocket Health, a digital mental healthcare company focused on therapy, psychiatry, and integrated care. The motivation behind the company was clear: mental healthcare has long been misunderstood and stigmatised. “People think therapy is only for extreme situations,” she explains. “We want to normalise it, to make it as routine as going to the gym or seeing a physician. For her, the mission is deeply personal and systemic at the same time. Mental health, she notes, influences every dimension of life, relationships, work, confidence, and decision-making. “As more people are opening up to these conversations, the care available to them must be credible and high-quality,” she emphasises. Quality at Scale Dr. Sinha’s role centres on building healthcare systems
