Heatwave warning: Are you prepared for it?
With heatstroke, hydration and health on everyone’s mind, experts advise how to protect yourself in the extreme weather
Planning that summer road trip soon? Think twice! For, the country is already in the grip of a heatwave. Since the beginning of the month, several states have been witnessing a rise in day temps (the mercury soared beyond 35°C in Kolkata and temps are already sizzling past 40° in Central India). The India Meteorological Department (IMD) has raised an alert and the Health Ministry, too, issued guidelines to tackle heat-related illnesses.
With impending dangers of heatstroke, we ask doctors to share measures of protection from the scorching days.
3 types of heat-related illnesses
Dr Divya Gopal, Internal Medicine, Sir HN Reliance Hospital and Research Centre, breaks these down.
“Heat cramps are the initial step, where severe muscle spasms, usually in the hands, calves, and feet, ensue from salt and water loss. The after effects of this usually lasts for 24 to 48 hours. Next, heat exhaustion, arises when the body’s core temperature rises to 101–104 degrees. It causes headache, mild fever, nausea, vomiting, increased thirst, numbness throughout, aches in the muscles, and decreased urine production,” she says, adding, “Some people may even pass out from a dip in blood pressure. Heat stroke is the last stage, a medical emergency and can be a potentially-lethal. Symptoms may include organ failure, dry, red skin, lack of sweating, confusion brought on by a lack of blood supply to the brain, and occasionally convulsions.”
Rise in cases of heat-related illnesses
As heatwave conditions escalate, there is a rise in illnesses across the country.
Dr Rajeev Gupta, CK Birla, Delhi, affirms, “The rising temperatures are already having various health effects, including increased respiratory infections, allergies, and gastrointestinal infections. These are accountable for 50-60 % of all emergency room cases.” He adds, “Heatwaves pose significant risks to human health, affecting cardiovascular and immune functions in multiple ways. Heat exhaustion and heatstroke that can result from long exposure is one thing, but it can lead to organ damage and mortality in severe cases.”
Who is most at risk?
With the situation set to worsen, Dr Santosh Kumar Aggrawal, Marengo Asia Hospitals Faridabad shares a key message – act immediately. “This can affect anyone, but the elderly population and young children, pregnant women, people with acute or chronic health conditions are more vulnerable. Parents should not allow their kids to go outside to play and should also not leave babies or young children in parked vehicles.”
He adds, “Heatstroke needs immediate intervention. In view of IMD’s heatwave warning, be extra cautious.”
