Government's plan to cap AC temperature between 20°C to 28°C gets a nod from health experts

Power Minister Manohar Lal Khattar's proposal to cap air conditioner (AC) temperatures such that they can't be set below 20 degrees Celsius and above 28 degrees Celsius may be met with equal heat and amusement from netizens, but experts urge that regulating AC temperatures can offer significant benefits for both personal health and the environment.
Calling it a one-of-a-kind experiment, Khattar on Tuesday stated that a new provision is being implemented to regulate air conditioning standards. 'The temperature standardisation for ACs will be set between 20°C and 28°C,' Khattar said.
Reacting to the news, Dr Manjusha Agarwal, senior consultant, internal medicine, Gleneagles Hospital, Parel, Mumbai, said that from a health perspective, it can be a good idea. 'Such capping will prevent sudden temperature shocks when moving between hot outdoor environments and extremely cold indoor spaces, reducing the risk of respiratory illnesses, joint pain, extreme cold, and even dehydration,' said Dr Agarwal.
Dr Narander Singla, lead consultant, internal medicine, CK Birla Hospital®, Delhi, concurred and shared that maintaining a moderate indoor temperature helps reduce the sharp contrast between outdoor and indoor air, which is particularly beneficial for individuals with respiratory issues such as asthma.
Experts point out that the reduced risk of dehydration helps prevent symptoms like headaches and fatigue. 'Furthermore, a temperature range between 24–27°C (75–81°F) is known to support better sleep quality, contributing to overall well-being,' added Dr Singla.
If the government's move is approved, it could change how Indians use their ACs at home and in public spaces like hotels and cars.
From an environmental perspective, setting the AC to a slightly higher temperature can substantially reduce energy consumption. This is a step toward sustainable energy use, especially during peak summer months when power grids are overloaded, said Dr Agarwal.
Experts urge this because it not only lowers electricity bills but also reduces greenhouse gas emissions, playing a vital role in the fight against climate change. 'By consuming less energy, we also reduce our carbon footprint, contributing to a more sustainable and eco-friendly future,' said Dr Singla.
He echoed the Bureau of Energy Efficiency's stance that raising the AC temperature by even one degree can reduce power consumption by six percent. Thus, such an increase could lead to reduced electricity bills for citizens.
It is also said that setting the thermostat to around 25.5°C (78°F) during summer strikes a good balance between comfort and energy efficiency. 'Even a small adjustment of just 1–2 degrees can make a noticeable difference in energy use and health outcomes. Making this simple change is a step toward a healthier lifestyle and a more sustainable planet,' said Dr Singla.

Deadline diet India's young workforce faces cardiac scare

Young Indians are increasingly facing heart issues. Doctors report a rise in cardiac cases among those in their 20s and 30s. Stress, lack of sleep, and unhealthy lifestyles are major factors. Sedentary jobs and poor diets contribute to the problem. Even post-Covid inflammation increases the risk. Sales of heart-related drugs have significantly increased. Tired of too many ads? Remove Ads Tired of too many ads? Remove Ads Tired of too many ads? Remove Ads For 31-year-old techie Kumar, long hours at work carrying well into the night often led to stress eating, coupled with an occasional drink (or two) to "take off the edge".The excesses magnified over the weekend, till one day when what he suspected was an episode of indigestion turned out to be a heart attack. Kumar, who doesn't want to reveal his full name, has now been put on a strict diet by his doctor. He has been asked to cut out all unhealthy food, stop eating out and is not an isolated case. Leading cardiologists are sounding the alarm bells as they see an increase in people in their 20s and 30s being hospitalised for cardiac issues. Stress, lack of sleep, pollution and working at odd hours have all contributed to the increase in heart disease among young people, said noted cardiologist Naresh Trehan."The numbers are worrisome; out of 34 beds in my ICU, nine are occupied by patients under 40," said Naveen Bhamri, vice-chairman of cardiology at Max Super Speciality Hospital in New Delhi's Shalimar Bagh, who performed an angioplasty on a 39-year-old this week. "A majority of my patients are in their 20s and 30s, who see long periods of inactivity due to being stuck at their desks, stressed out by the constant urban hustle and pressure to hit corporate targets."Nishith Chandra, director, interventional cardiology at Fortis Escorts Heart Institute in the national capital, said he is seeing 10-20 patients in the age group of 20-30 years every month with heart-related key drivers behind this trend are sedentary lifestyle, lack of exercise, high stress, poor sleep and mental health issues, Chandra said. "Undiagnosed hypertension, post-Covid heart inflammation, use of steroids and unsafe gym supplements, smoking, alcohol and recreational drug use are some other factors," he across the country are reporting increased cases of young professionals having cardiovascular diseases, sudden cardiac arrests and heart attacks."Not all of them have the typical triggers like diabetes, hypertension, obesity and family history. Recent data shows that one in four individuals having heart attacks are aged 40 and under," said M Sudhakar Rao, consultant - cardiology at Manipal Hospital, Sarjapur, Bengaluru Tight deadlines and work pressure, constant hustle culture and impending burnout are causing Indian professionals to remain in sedentary positions for most of the day, get less sleep, and turn to unhealthy, processed foods - all of which can contribute significantly to the risk of heart attacks, say medical is the diabetes and hypertension capital of the world, and people are genetically more predisposed to getting heart diseases, often earlier than their counterparts in the West, said Mukesh Goel, senior consultant - cardiothoracic and heart and lung transplant surgery at Delhi's Indraprastha Apollo Hospitals. "There's a difference of 10-15 years with the West."Telehealth consultation data from Plum shows two-thirds of cardiac consultations come from the 25-40 age group, showing a premature cardiovascular ageing in India's prime working demographic."We've observed that 71% of Indian working professionals are at moderate risk of chronic disease, showing warning signs across blood pressure, diabetes, cholesterol and obesity," Saurabh Arora, cofounder of the insurtech startup, told has increased the risk further, said Trehan. "People who got serious Covid actually have much higher chance of developing heart disease because there is inflammation of the arteries, and the heart muscle became weak. So, if those who got serious Covid were not checked out then they should get it now".Sales of drugs in the cardiac category have risen almost 50% in five years to ₹30,723 crore in the 12 months through May 2025, according to data from market research firm PharmaTrac."Consumption of lipid-lowering agents, antianginal therapies and heart failure therapies have almost doubled in the last five years with Indians experiencing heart disease 5-10 years earlier than the global average. The age group has now come down to 30-40 years from earlier 50-60 years, said Sheetal Sapale, vice-president, commercial at of cardiac products increased 11.7% in 2024 compared with the year before.

Millennials lead yoga adoption with 74% practising regularly: Report

A new study finds that 74 per cent of millennials include yoga in their daily wellness routines, making them the leading age group in regular practice, closely followed by Gen X at 70 per cent. Conducted by ICICI Lombard General Insurance with a sample of nearly 1,000 respondents across both metro and non-metro areas, the pan-India study released on International Yoga Day explores health practices, motivations, and awareness levels -- providing a snapshot of how Indians are weaving wellness into their everyday routines. "As stress and burnout become the new epidemic, yoga is not just making a comeback it's becoming a daily essential. India's timeless contribution to global health, yoga, offers a powerful, holistic path to living well. "Our latest report shows that 74 per cent of millennials now practise yoga regularly a compelling indicator that today's middle-aged are investing not just in longevity, but in ageing well," said Sheena Kapoor, head marketing, corporate communications and CSR at ICICI Lombard. The findings also reveal that yoga has moved beyond a niche practice to become mainstream in India, with 72 per cent of respondents practising it regularly and another 18 per cent doing so occasionally. However, according to the report, the gap between awareness and experience continues to be significant -- "while 66 per cent of respondents recognise that yoga can reduce stress and anxiety, only 52 per cent have personally experienced these benefits". In addition to yoga, daily walks (69 per cent) and maintaining a balanced diet (68 per cent) rank among the top health practices adopted to enhance overall well-being. The report notes that Gen X is at the forefront of embracing these habits, with men showing slightly higher participation than women. The report also highlights the rising appeal of online formats but points out that nearly half (45 per cent) of participants still favour studio classes, while 28 per cent opt for livestream sessions and 13 per cent rely on apps or pre-recorded videos.
