Heatstroke is a serious heat- illness caused when the body can no longer regulate its temperature. If not treated quickly, it can affect the brain, heart, kidneys and muscles.

Who Is Most At Risk?

Children, senior citizens, pregnant women, people with chronic illnesses, and those working outdoors for long hours are among the most vulnerable during extreme summer heat.

Early warning signs of heatstroke

Severe Headache And Dizziness

One of the most common early symptoms is a sudden headache, heaviness in the head or throbbing pain. Many people also feel dizzy or light-headed. This may indicate rising body temperature and heat stress.

Dry Mouth And Extreme Thirst

Excessive heat can quickly lead to dehydration. A dry mouth, sticky lips and constant urge to drink water may be early warning signs.

Sudden Weakness And Tiredness

If the body suddenly feels drained, weak or unable to continue routine work, it may be struggling to cope with heat exposure. Some people may even feel difficulty walking.

Changes in sweating pattern

Some people sweat excessively, while others may suddenly stop sweating despite intense heat. Both situations can be warning signals that the body is failing to cool itself properly.

Restlessness Or Confusion

Heat can also affect the brain. A person may feel anxious, irritated, unable to focus, confused or unusually restless. Rapid heartbeat may also occur.

Feeling Feverish Or Unusually Hot

If the body feels hotter than normal, flushed or mildly feverish, it may be a sign that internal temperature is climbing.

What To Do Immediately

Move the person to a cool or shaded place. Drink water or oral rehydration fluids if conscious. Loosen tight clothing, apply cool clothes, and rest. If confusion, fainting, vomiting or high fever develops, seek urgent medical help.

How To Prevent Heatstroke

Wear loose cotton clothing and keep the head covered when outdoors. Avoid stepping out during peak afternoon heat if possible. Drink water regularly even if not thirsty. Coconut water, buttermilk and lemon water can help maintain hydration. Those working in the sun should take frequent breaks in shade.

Why Early Action Matters

Ignoring early symptoms can allow dehydration and overheating to worsen rapidly. Timely rest, cooling and hydration can prevent heat exhaustion from progressing to heatstroke.
