Doctor says ‘immunity begins at home'; shares smarter habits for children against new COVID-19 variant
A new COVID-19 variant is on the rise, and has been identified as the "Nimbus" variant, also known as NB.1.8.1, known for causing a 'razor blade throat', per reports. The WHO assessed the additional risk to the global public as currently low, and existing COVID-19 vaccines to be effective in preventing severe disease. However, taking precautions, especially with kids, shouldn't be ignored. The new COVID variant appears to cause milder illness than earlier variants, but its rapid spread still poses a threat, particularly to children.

In an interview with HT Lifestyle, Dr Michelle Shah, paediatric lifestyle medicine specialist and public health professional, shared smarter habits to boost your child's immunity during the resurgence of the Omicron sub-variants like JN.1.16, LF.7, and NB.1.8.1
'India is once again seeing a gradual resurgence of COVID-19 cases, driven by highly transmissible Omicron sub-variants like JN.1.16, LF.7, and NB.1.8.1. Though these strains appear to cause milder illness than earlier variants, their rapid spread still poses a threat, particularly to children under 12 and those with chronic conditions such as asthma, diabetes, or immune compromise. Vaccination remains vital, but daily routines are what quietly train a child's immune system over time,' Dr Michelle said.

She suggested that families go beyond the basics to build immunity in ways that are science-backed, yet surprisingly simple. Here's what she suggested: 1. Feed the clock, not just the child
'Our immune cells follow circadian rhythms. Eating meals at consistent times (especially a protein-rich breakfast within 90 minutes of waking) can optimise immune regulation and reduce inflammatory markers. Erratic eating disrupts metabolic-immune synchrony,' Dr Michelle explained. 2. Introduce morning natural light before screens
Morning sunlight within the first hour of waking helps reset the circadian clock and boosts serotonin production. 'It indirectly supports immune homeostasis. Open curtains, step outside or have breakfast near a window before reaching for devices,' she suggested. 3. Cultivate a weekly 'nature dose'
'Just 2 hours per week in green spaces reduces pro-inflammatory cytokines and enhances Natural Killer (NK) cell activity, your child's first line of viral defence. Whether it's a nature walk, outdoor story time or barefoot garden play, nature is medicine,' Dr Michelle said. 4. Teach the 'sun-sleep-soil' triangle
Lastly, the expert advised empowering older children by teaching them a simple formula: 'Sunlight daily + Good sleep + Time in soil = Strong body soldiers.'
'Framing immunity as something they can 'train' makes them more likely to adopt healthy habits,' she added. Are our schools prepared?
Dr Michelle also stressed that with rising cases, we must ask ourselves, 'Are our schools prepared?' Here's what schools and parents can do together: Ensure proper ventilation in classrooms and common areas. Cross-ventilation, open-air classrooms or simple HEPA filters can reduce airborne transmission effectively.
Reinforce hand hygiene habits with handwashing stations. When handwashing is integrated into transitions (after play, before snacks), it stops being a 'rule' and becomes a reflex.
Keep sick children at home. Staying home when unwell should be reframed as a civic contribution, not an inconvenience.
Monitor absentee spikes to detect early signs of outbreaks.
'Let's not wait for the numbers to rise dramatically before reactivating basic safety protocols. A proactive approach can prevent the need for drastic measures later,' she concluded.

‘Nicotine addiction hasn't disappeared, it has simply shape-shifted'
Smokeless tobacco is the number one problem in India and there is an urgent need to strengthen laws and regulations to address it effectively,' Dr Shalini Singh, director of the Indian Council of Medical Research-National Institute of Cancer Prevention (ICMR-NICPR) and the World Health Organisation-Framework Convention on Tobacco Control (WHO-FCTC) Global Knowledge Hub on Smokeless Tobacco told The Indian Express. On the sidelines of the World Conference of Tobacco Control under way at Dublin, Dr Singh observed that globally, cigarette smoking is on the decline — especially in high-income countries, where public health regulations have tightened and consumer behavior is shifting. 'But nicotine addiction hasn't disappeared; it has simply shape-shifted. The rise of electronic nicotine delivery systems (ENDS), synthetic nicotine pouches, and 'flavoured wellness' lozenges represents a quiet but aggressive reinvention of the nicotine business. These products are marketed as cleaner, safer, and even medicinal — often using the language of 'harm reduction'. While India has banned e-cigarettes, these new delivery systems pose a serious public health risk in countries with poor implementation of regulations,' Dr Singh said. India is already home to one of the largest populations of smokeless tobacco (SLT) and bidi users globally. According to the Global Adult Tobacco Survey (GATS) 2016–17, over 199 million Indians use SLT, 72 million smoke bidis, whereas only 37 million smoke cigarettes. Less than 4 per cent of tobacco users use any cessation pharmacotherapy, and over 70 per cent quit without formal help. 'This makes India an especially vulnerable target for the tobacco industry's new nicotine expansion strategy,' Dr Singh said. Harm reduction, when implemented as part of a comprehensive cessation strategy, has clinical value. But the tobacco industry has co-opted the term 'harm reduction' to further its own interests of reduced regulation and to expand its user base. While India banned e-cigarettes in 2019 under the Prohibition of Electronic Cigarettes Act, experts said the same industry has repackaged nicotine in non-combustible, e-cigarettes adjacent forms — such as synthetic nicotine pouches and gums — often marketed as herbal, Ayurvedic, or wellness products on Indian e-commerce platforms. 'This represents not only a strategic circumvention of the e-cigarette ban but also a continuation of the industry's practice of promoting products that protect profits while presenting a facade of supporting smoking cessation,' Dr Singh added. India permits over-the-counter (OTC) sale of 2 mg nicotine gums and lozenges, based on the assumption that easier accessibility would enhance tobacco cessation efforts. The 2 mg NRT formulation, particularly when used with behavioural counselling, can play a crucial role in reducing dependence on smoking tobacco. Global evidence is clear: NRTs are most effective when used with structured counselling and support, not when taken in isolation. Many low- and middle-income countries (LMICs), including India, have NRTs in OTC markets and require integration with comprehensive cessation services. In India, the effectiveness of OTC NRT is further undermined by systemic challenges: the very low cost of smokeless tobacco (SLT) products like gutkha, khaini, and bidis; the online sales of nicotine products frequently bypass age restrictions;and the economic burden of NRT — where one week's supply often costs more than a month's worth of SLT or bidi. Without counselling support and affordability measures, OTC NRT risks becoming another market commodity rather than a true cessation aid,' Dr Singh pointed out. Long-term use of nicotine — whether through vaping, pouches, or even unsupervised NRT — poses real risks. Yet, these products are increasingly available through online platforms in India, marketed with no warning labels, no age-gating, and no evidence-based cessation claims, Dr Singh cautioned. Urgent policy priorities include banning of flavoured and industry-manufactured non-combustible nicotine products, including gums and pouches not intended for supervised cessation. There is a need to tightly regulate OTC NRT, especially in flavours and formulations attractive to youth; regulate all online sales of nicotine products with mandatory age verification, licensing, and product labelling.

Are you always cleaning your glasses? It can be cataract: Doctor shares 6 early warning signs to know
Cataract is an eye condition that progresses very slowly, often making early detection challenging. However, one of the earliest warning signs is foggy or blurred vision. Foggy vision is one of the early symptoms of cataract.(Freepik) In an interview with HT Lifestyle, Dr Supriya Sriganesh, ophthalmologist, cataract and refractive surgeon, Nethradhama Super Speciality Eye Hospital, Bangalore said, 'By the time the patient really understands that the vision is blurry, they would have already gotten used to that lower degree of vision. And that's why they let it progress until it reaches a much later stage. Some people notice very late that the cataracts need to be operated on.' Also read | What are cataracts and how they can be treated Dr Supriya Sriganesh further shared the early signs of cataract we should be aware of to prevent progression of this condition: 1.
