"Heatwave conditions are likely over Gujrat, Rajasthan, Haryana Chandigarh & Delhi and Punjab during next 4-5 days," the IMD had warned on April 6. "Mainly clear sky. Heat wave conditions very likely at most places over Delhi. The maximum and minimum temperatures over Delhi are likely to be in the range of 40 to 42°C and 21 to 23°C respectively. The predominant surface wind will likely be from the east direction with a wind speed of 10-12 kmph during morning hours. The wind speed will gradually decrease becoming 04-06 kmph from the southeast direction in the afternoon. It will increase becoming less than 10 kmph from the southeast direction during evening and night," it had forecasted for April 8.

Since summer has already begun, it is important to follow preventive measures to stay safe. Before that one must know how heatwaves affect human health across all age groups.

Heatwaves aren’t just annoying or uncomfortable—they’re actually dangerous. And the worst part? They mess with people across all age groups—from tiny toddlers to our cool, wise grandparents. So whether you’re a college student baking in your PG room or a working parent running errands, this kind of heat affects you more than you might think.

Your body’s like a car—it runs best within a certain temperature range. When the weather gets too hot, your body tries to cool itself off by sweating. But in a heatwave, especially when there’s also high humidity, this cooling system can start to fail. Your internal temperature starts rising, you lose water and salt through sweat, your heart works harder to cool the body, you feel sluggish, dizzy, or confused and in extreme cases? You collapse. Or worse.

Babies and small children are super vulnerable in the heat
The little bodies don’t regulate temperature well, and they can’t exactly tell you when they’re overheating. Dehydration sets in faster. They may get irritable, drowsy, or vomit. There's a high risk of heat rash and heat exhaustion.

Keep them indoors during peak hours (12 PM–4 PM). Dress them in light cotton clothes. Offer fluids often—even if they’re not asking. NEVER leave them alone in a car, not even for five minutes.

Children and teens have a playful energy; keep them safe during intense heatwave
Kids love to run around, even if the sun’s boiling overhead. But that playful energy can turn dangerous in a heatwave. Dehydration—they forget to drink water! Sunburns if they’re not wearing sunscreen. Heat cramps and fatigue after physical activity.

Encourage regular water breaks. Don’t push them to play outside during peak heat. Use hats, sunglasses, and SPF generously. Cool them down with a wet towel or cold shower if needed.

Young adults need to pay attention to the symptoms
This is the group that thinks they’re invincible. Hustlers, gym goers, bikers, and people trying to catch up with deadlines, workouts, or social scenes. Problem? Many ignore the signs of heat exhaustion until it gets serious.

The common warning signs are exhaustion or fainting while commuting or working outdoors, headaches, nausea, or irritability, poor concentration (yep, the brain doesn’t function well in high heat) and electrolyte imbalance from too much sweating.



Hydrate even before you feel thirsty. Avoid heavy workouts in the sun. Shift to early mornings or late evenings. Ditch the tight clothing—loose, breathable fabrics are your best friend. Limit alcohol and caffeine—they dehydrate you faster.

Adults tend to ignore heatwave sign, be careful especially if you have existing health conditions
This group usually has the most responsibility and the least time to take care of themselves. Many are juggling kids, work, errands, and elderly care—so it’s no wonder they ignore symptoms.

Health issues that get worse in the heat:

• High blood pressure
• Diabetes-related dehydration
• Heart problems
• Migraines and sleep disorders

Even mental health can take a dip. The fatigue, crankiness, and sleep disturbances from relentless heat can lead to anxiety and mood swings.

Keep rooms well-ventilated and use fans strategically if there's no AC. Soak your feet in cold water or place a cold pack on your neck to cool down. Plan errands early morning or post-sunset. Watch your blood sugar and BP regularly if you have a chronic condition.

Older adults suffer the most
Now, this is the age group that suffers the most—and often quietly. People over 65 often have a reduced ability to sense heat, so they may not even realize how hot they’ve gotten until it’s too late. Also, they might be on medications that affect hydration, or they might avoid drinking too much water out of fear of needing frequent bathroom trips.



Major risks for this age group are heatstroke, which can happen without warning, sudden falls due to dizziness or low BP, worsening of existing conditions (like heart or kidney issues) and confusion or delirium due to dehydration

Check in on elderly family members often. Ensure they have access to fans, cool drinks, and shade. Encourage water-rich foods like fruits (melon, cucumber, etc.) Watch for early signs: dry mouth, confusion, excessive tiredness.

Warning signs to not ignore
Across all age groups, these red flags are a sign you should act immediately:

• Excessive sweating or lack of sweat
• Red, hot, and dry skin
• Rapid pulse
• Dizziness, confusion, or fainting
• Nausea or vomiting
• Muscle cramps

If someone shows any of these, get them into a cool place, have them sip water, and call for medical help if they don’t start improving fast.

Be cool, stay shaded, and take care of yourself and your people.
