Working in AC and facing summer heat? Eight tips to stay fit and energised
With temperatures in North India already exceeding 40 degrees Celsius, for office-goers, a crisp, chilled office floor feels like a sanctuary, an escape from the furnace outside. But the moment one steps out for a chai break or to head home, the heat ambushes them like a wall of fire—unforgiving and unrelenting. This daily dance, from the embrace of air-conditioning to the fury of the sun and back again, may seem routine, even harmless. Yet, this constant tug-of-war between extremes quietly chips away at people's health in ways seldom noticed—until the body finally begins to protest.
Dr Satish Koul, senior director and unit head, internal medicine, Fortis Memorial Research Institute, Gurugram, said in a telephonic conversation with Business Standard, 'Rapid transitions from air-conditioned indoor environments to hot outdoor conditions can place significant stress on the body's temperature regulation mechanisms. Your body struggles to adjust its thermoregulation rapidly. This may weaken the immune response, increasing susceptibility to headaches, colds, sore throat, and other infections—even heat exhaustion and sudden fatigue due to the shock to the immune system.'
'Additionally, prolonged exposure to low AC temperatures can lead to joint stiffness or muscle pain, especially in sedentary office environments,' he added. He also said that these temperature shocks not only stress the respiratory system but can also affect the cardiovascular system, especially in people with underlying health conditions.
Highlighting that AC systems can also spread allergens, bacteria, and viruses—especially if filters are not regularly cleaned—he said, 'You should be mindful of regular maintenance of AC systems at your offices. Dirty filters can circulate harmful particles, leading to respiratory issues.' Also Read:

Dryness and dehydration
Headaches
Sore throats
Colds from immune shock
Respiratory issues and allergens spread
Worsening of asthma or allergic rhinitis
Muscle stiffness or joint pain from prolonged cold exposure
'People with pre-existing respiratory conditions often notice their symptoms worsening due to this abrupt exposure,' adds Dr Koul.
Top tips to protect your health while working in AC this summer
1. Wear breathable clothes for better temperature control
Opt for light, loose-fitting, and breathable fabrics such as cotton. Avoid synthetic materials as they trap heat and sweat, making the transition more uncomfortable. 'Carry a light jacket or scarf to balance out the cold indoors—it helps your body adapt better and prevents sudden chills,' says Dr Koul.
2. Use sun protection before stepping outdoors
Use an umbrella, cap, and sunglasses to shield yourself from direct sun exposure. Cover your mouth and nose with a scarf to minimise the shock from hot air.
3. Stay hydrated throughout the workday
Frequent temperature changes can dehydrate the body. Drink water regularly, even before you feel thirsty. Include natural fluids like coconut water, buttermilk, or lemon water to restore electrolyte balance. 'Cold air can suppress your thirst. Keep water at your desk and sip throughout the day to stay energised and regulate your body temperature,' said Dr Koul.
4. Set AC temperature to a healthy range (24–26°C)
Maintain the office AC at a moderate temperature, ideally between 24 degrees Celsius and 26 degrees Celsius. This reduces the temperature gap between indoors and outdoors. 'Extremely low settings are not only uncomfortable but harmful. Ideally, keep the AC between 24–26 degrees Celsius,' recommends Dr Koul. Also Read:
5. Eat immunity-boosting foods and stay active
'Include fruits, greens, nuts, and seeds in your diet. Even a short daily walk helps your body stay active and alert.'
6. Don't ignore early symptoms of discomfort
If you develop a sore throat, headache, fever, or any breathing discomfort after exposure to sudden temperature changes, consult a doctor. Early intervention can prevent complications.
7. Practice deep breathing to ease respiratory strain
'AC air can constrict airways. Simple deep breathing exercises or pranayama can help ease breathing and protect lung health.'
8. Let your body adjust before stepping into the heat
If possible, avoid stepping out immediately after long exposure to cold air. Give your body a few minutes in a non-air-conditioned indoor environment before heading outside. 'Don't rush from your desk to the outdoors. Let your body adjust—turn off the AC a few minutes before stepping out,' said Dr Koul.
'While we can't avoid the heat, small changes in routine can prevent bigger health issues. It's about listening to your body and adjusting smartly,' concludes Dr Koul.

How climate change is worsening physical and mental stress in rural India
As the world turns its attention to carbon emissions and global temperature rise, a quieter yet devastating health crisis is unfolding in rural India, one that is deeply intertwined with climate change but rarely heat-induced strokes and kidney failures to growing mental distress, experts warn that the human cost of extreme weather, especially on women, is rising sharply."In the heart of rural India, the escalating heat is more than a discomfort, it's a silent crisis that is reshaping the health and well-being of entire families,' said Neeraja Kudrimoti, Lead, Climate Action at Transform Rural India, a development design RISING TEMPERATURES, RISING HEALTH RISKSIndia experienced its hottest February in over a century in 2023, and this year's summer has already seen heatwave warnings in multiple to the India Meteorological Department (IMD), several districts faced temperatures above 45 degrees Celsius in May each passing summer, doctors are seeing a surge in strokes, particularly among outdoor workers. From heat-induced strokes and kidney failures to growing mental distress, experts warn that the human cost of extreme weather is rising sharply. (Photo: PTI) "Recurring heatwaves are triggering strokes even at young ages. In deep rural pockets, climate change is a felt reality, impacting livelihoods, bodies and minds," said Shyamal Santra, Associate Director, Health & Nutrition at Transform Rural are especially vulnerable. Kudrimoti explained how rural women, often involved in outdoor agricultural labour and caregiving at home, suffer disproportionately."The gendered impacts of heat stress are profound. Women often sacrifice their health and psycho-social well-being for the sake of their families," she added burden of fetching water, collecting firewood, and caring for the elderly under scorching conditions takes a heavy toll.A 2024 report from the International Labor Organization (ILO) revealed that 2.41 billion workers are exposed to excessive heat worldwide, of whom nearly 19,000 succumb health impacts of this exposure are many from heat stroke and exhaustion to heat rashes and physical injury to cardiovascular and kidney FAILURE AND WATER CRISISAccess to clean water is worsening. As water sources dry up or become saline, rural families are forced to rely on contaminated supplies."Chronic dehydration and high fluoride intake from poor water sources are contributing to rising cases of kidney failure," Santra issues are particularly alarming in drought-prone and flood-affected areas where water quality is a persistent challenge. As water sources dry up or become saline, rural families are forced to rely on contaminated supplies. () A recent study published in The Journal of Climate Change and Health, revealed that while climate change response efforts in cities are urgent, they often overshadow the "climate-sensitive health challenges in India's rural regions where residents endure severe heat and air pollution but have far fewer resources to adapt."MENTAL DISTRESS: THE SILENT SUFFERINGThe crisis doesn't end with physical health. Erratic weather and frequent crop failures are creating economic hardships, leading to climate-induced often move to cities in search of work, leaving women behind to bear the emotional and financial burdens alone. "This deepens anxiety, isolation and mental stress. It impacts the overall well-being of rural communities," said shared a striking observation from the field: "As a didi once said, cranky kids and unrealistic expectations from the woman in the house are a recipe for crisis – 'job not done, care half given'."'COOLING MUST BECOME A RIGHT'Most rural homes lack access to fans, let alone air-conditioning. The concept of cooling as a public health necessity is still absent in policy is time to recognise cooling as a fundamental right, a 'right to cool', essential for health, dignity, and gender equity," Kudrimoti stressed the suggested solutions like community cooling spaces, climate-resilient housing, widespread tree planting, and decentralised cooling technologies powered by renewable energy."We must centre women's voices in climate adaptation strategies to lift this hidden toll of heat," she said that beyond carbon, climate action is about people, strengthening local ecosystems, supporting women's collectives, and rooting solutions in dignity and India faces more frequent and intense heatwaves, it's important to recognise how climate change is affecting people, especially women, so that better solutions are made for Reel
