Summer Health Alert: Dehydration Cases Rise Across India

Doctors warn of silent health risks as extreme heat and humidity take a toll

Kolkata, May 19:

The heat is visible.

The danger is not always.

As temperatures continue to rise across India, hospitals are witnessing a surge in dehydration-related cases, many of which begin with mild symptoms but quickly escalate if ignored.

In West Bengal, particularly in coastal regions like Haldia, the situation is compounded by humidity—making the body lose fluids faster while reducing its ability to cool down.

Doctors say this is where the risk begins.

“Most patients don’t realise they are dehydrated until they feel weak or dizzy,” said a Kolkata-based physician. “By then, the body has already lost a significant amount of fluids.”

What Is Dehydration and Why It Happens Faster in Summer

Dehydration occurs when the body loses more fluids than it takes in.

During extreme heat, sweating increases.

That means more fluid loss.

If you are not replacing that fluid regularly, the body begins to struggle—affecting energy levels, concentration, and even vital organ function.

Humidity makes it worse.

Sweat stays on the skin instead of evaporating, which reduces the body’s natural cooling system.

Warning Signs You Should Not Ignore

Doctors advise watching for early symptoms:

• Dry mouth and lips

• Fatigue and weakness

• Headache or dizziness

• Muscle cramps

• Dark yellow urine

• Reduced sweating (in severe cases)

Even mild symptoms can worsen quickly in extreme weather.

Who Is Most at Risk

Not everyone experiences heat the same way.

High-risk groups include:

• Outdoor workers (construction, transport, delivery)

• Elderly individuals

• Children

• People with diabetes or heart conditions

• Those who consume less water regularly

In industrial towns like Haldia, where many workers spend long hours outdoors or in high-temperature environments, dehydration cases are rising steadily.

How Much Water Is Enough?

There is no one-size answer.

But doctors suggest:

• At least 3–4 litres of water daily in extreme heat

• More if you are sweating heavily

• Include ORS, coconut water, and fruit juices

• Eat water-rich foods like watermelon, cucumber, and oranges

The key is not to wait until you feel thirsty.

Thirst comes late.

Dehydration begins earlier.

Daily Habits That Can Protect Yo

Simple changes can reduce risk significantly:

• Avoid stepping out between 11 AM and 4 PM

• Wear loose cotton clothes

• Use umbrellas, caps, or scarves

• Take regular breaks if working outdoors

• Keep a water bottle with you at all times

Why Haldia and Coastal Bengal Are More Vulnerable

Unlike northern India’s dry heat, coastal areas face humid heat, which feels heavier and more exhausting.

Even when temperatures are lower, the heat index—which combines heat and humidity—can be dangerously high.

That’s why people often feel more tired in coastal regions.

And why dehydration can happen faster.

What Doctors Are Saying Now

Medical professionals are urging people not to ignore early warning signs.

“Dehydration is preventable,” said a health official. “But it requires awareness. People must understand that drinking water is not optional in this weather—it’s essential.”

Hospitals are also preparing for increased patient load as the heatwave continues.

Looking Ahead

The current heatwave is expected to persist over the next few days, with only gradual relief in some regions.

That means the risk will remain.

And so will the need for caution.

Because dehydration does not arrive suddenly.

It builds quietly—one skipped glass of water at a time.

Until the body begins to feel it.

And by then, recovery takes longer than prevention
