This summer's already showing signs of being intense. Temperatures are up, humidity's higher, and heatwaves are lasting longer. More people are landing up at clinics and hospitals with signs of extreme heat exhaustion — and in many cases, it's heatstroke.

Heatstroke happens when the body overheats and cannot cool itself down. It often builds up gradually during exposure to high temperatures, especially in humid weather. This summer, the risk is higher due to longer heatwaves and rising humidity levels across many parts of the country.

It is important to understand what heatstroke looks like, who is at risk, how it affects you in varied ways, including the epidermis, as per the experts at the skin specialist hospital in Delhi and how to deal with it early. Ignoring the signs can lead to serious health complications.

What Actually Happens During Heatstroke?

The body keeps a stable internal temperature — usually around 37°C — by sweating and releasing heat. But in very hot or humid weather, sweating alone isn't enough. If you're out too long or not drinking enough water, your temperature can climb above 40°C.

When that happens, the body stops functioning as it should and you may start noticing symptoms of sun stroke. Organs can come under stress. Without quick action, heatstroke can cause long-term damage or become life-threatening, like heart disease.

It Doesn't Just Affect Outdoor Workers

There's a common belief that heatstroke only hits people doing phy

sical labour in the sun. That's not true anymore. Here's who's at higher risk:

● Children, especially toddlers

● Older adults, particularly those who live alone or with limited cooling

● People with long-term health conditions, including diabetes, heart disease, or obesity

● Anyone not drinking enough water

● People exercising or walking outside during peak heat

● Workers exposed to the sun for hours — delivery agents, security guards, traffic police 

Even a short trip in the sun without water or shade can cause problems if the body starts heating up too quickly, thereby showcasing the heat stroke symptoms.

Signs That Something's Wrong

Heatstroke doesn't always give a loud warning. It builds up and can catch people off guard. Watch out for:

● Body temperature above 40°C

● Red, hot, dry skin (or heavy sweating that doesn't seem to help)

● Headache, confusion, or irritability

● Dizziness or a faint feeling

● Nausea or vomiting

● Fast heartbeat

● Muscle cramps or weakness

● Loss of balance or passing out

If someone looks spaced out, isn't responding properly, or collapses in the heat — don't assume it's tiredness. It could be heatstroke.

You may notice dehydrated skin, dry lips, or a tight feeling on the face after being in the heat for too long. These are early signs that your body is low on fluids.

What To Do Immediately

If someone shows signs of heatstroke, don't wait to see if they'll recover on their own.

1. Get them out of the sun — move indoors or into the shade

2. Cool their body — use cold water on the skin, place a wet cloth on the neck, forehead, and underarms

3. Remove tight or extra clothing

4. Don't force water if the person is drowsy or disoriented

5. Call for medical help; go for an emergency if required at the best heart hospitals. This is not something to treat casually.

Even if the person starts feeling better after cooling down, they should still be checked by a doctor. The internal effects of heatstroke may not be obvious straight away.

Staying Safe This Summer

You don't need expensive gear or complicated plans. A few small changes can go a long way.

1. Drink regularly, not just when thirsty

Keep a bottle nearby. If you're sweating a lot, consider ORS or lemon water with salt and sugar.

2. Avoid stepping out during peak heat

Between 11 AM and 4 PM, the sun is strongest. If you have to go out, wear a cap and carry water.

3. Wear light, breathable clothes

Loose cotton or linen helps. Stick to light colours and avoid synthetic fabrics that trap heat.

4. Don't overexert

Running errands, walking long distances, or exercising during peak heat puts extra pressure on the body, especially the cardiovascular muscles as the best heart hospitals state. If you feel dizzy, pause and rest.

5. Cool your living space

Use curtains to block harsh sunlight. Turn on fans or coolers. If you live in a warm flat, consider spending some time in public spaces like libraries or malls when the heat is unbearable.

6. Never leave anyone in a parked car

Even five minutes in a locked vehicle can be dangerous — especially for children or older adults.

7. Look After What You Eat

Some foods hold traditional value in cooling the body. For instance, onions — even dehydrated onions used in chutneys or salads — are believed by many to offer some relief in the heat.

8. Eat Light and Smart

Heavy meals can make the body work harder. Go for lighter options like fruits, curd, and home-cooked meals. If you're carrying food to work or on the go, simple dishes made with dehydrated vegetables can be a good option — they're light, easy to pack, and don't spoil quickly.

Summer 2025: Why It Matters More This Year

This year, more places are seeing repeated heatwaves. Nights are warmer, giving the body less time to recover. Access to cooling isn't equal for everyone, especially in crowded homes or areas with limited electricity.

It's no longer enough to "just drink water" and carry on. Paying attention to heat exposure — and acting early — matters more than ever. In case something happens, do keep notes of remedies for sun stroke.

Keep an Eye on Others, Too

Check in on older neighbours, workers in your area, and even delivery personnel who may be spending long hours outside. A glass of water or a short rest in the shade can help someone stay safe.

Final Thought

Heatstroke isn't just a rare medical case. It's a real problem in regular settings — during commutes, errands, walks, or a hot day at home. If you know what to look for and take small steps to protect yourself, it's possible to avoid it completely. If you still have any doubts, feel free to reach out to the doctors at our hospital, a prominent skin specialist hospital in Delhi and other locations.

Stay cool, stay aware, and help others do the same.

Frequently Asked Questions

Which Hospitals Are Best for Heat Stroke Treatment?

In India, multi-speciality hospitals with strong emergency care like Apollo, Fortis, Max Healthcare, and Park Hospitals are equipped to treat heatstroke. Look for 24/7 emergency services, internal medicine specialists, and ICU support. Quick access matters more than just a brand—go to the nearest well-equipped hospital.

Can Heatstroke Be Fatal? How to Avoid It?

Yes, heatstroke can be life-threatening if not treated quickly. You can avoid it by staying out of direct sun during peak hours, drinking plenty of fluids, wearing light clothing, and using fans or cool showers to regulate your body temperature.

What Are Signs One Is Having a Heatstroke?

High body temperature (above 40°C), dry skin, confusion, nausea, headache, fast heartbeat, and even fainting. It's a medical emergency—call for help immediately if you notice these signs.

What's the Difference Between Heat Stroke and Heat Exhaustion?

Heat exhaustion is the early stage: heavy sweating, weakness, dizziness. Heatstroke is more serious—your body stops cooling down and overheating damages organs. No sweating, mental confusion, and risk of collapse.

Why Does Dehydration Cause Headaches?

When you're dehydrated, your brain temporarily contracts due to fluid loss, triggering pain. It also reduces oxygen flow to the brain, making it worse.
