Heat wave health risk

India is currently experiencing intense heat waves, with temperatures soaring to dangerous levels across many cities. What many people do not realise is that extreme heat is not merely “summer discomfort.” Heat can silently affect the brain, heart, liver, kidneys, hormones, sleep, mood, immunity, and even trigger life-threatening emergencies.

Hydrate yourself this sumer

According to the World Health Organization (WHO) on heat and health, prolonged exposure to excessive heat can lead to severe dehydration, cardiovascular strain, heat stroke, and worsening of chronic illnesses.

Every year, thousands of people suffer from dehydration, exhaustion, heat stroke, blood pressure fluctuations, acidity, migraine attacks, skin disorders, fatigue, anxiety, and worsening of chronic diseases due to excessive heat exposure.

Elderly at high risk for heat wave

For children, elderly individuals, diabetic patients, people with high blood pressure, obesity, anxiety disorders, liver disorders, or weak immunity — the risk becomes even greater.

Why Heat Waves Are Dangerous

Symptoms of dehydration

When the body is exposed to prolonged high temperatures, it struggles to maintain its normal internal temperature.

Normally, the body cools itself through sweating. But during extreme heat:

Excessive sweating causes water and electrolyte loss
Blood becomes thicker and circulation becomes strained
The heart works harder
The brain becomes fatigued
Digestion weakens
Sleep quality deteriorates
Stress hormones rise

Symptoms of Heat stroke

Research published by Harvard Health Publishing on dehydration and heat illness explains how dehydration affects circulation, cognitive function, and organ performance.

Even mild dehydration can lead to:

Fatigue
Poor concentration
Irrability
Headache
Acidity
Muscle cramps
Weakness
Mood changes

Diseases and Health Problems Triggered by Extreme Heat

1. Heat Exhaustion

Heat exhaustion

This occurs when the body loses excessive water and salts.

Symptoms:

Heavy sweating
Weakness
Dizziness
Nausea
Rapid heartbeat
Headache
Muscle cramps
Faintness

If ignored, this can progress to heat stroke.

The Centers for Disease Control and Prevention (CDC) heat illness guide describes heat exhaustion as an early warning stage before severe heat emergencies occur.

2. Heat Stroke — A Medical Emergency

Severe heat stroke

Heat stroke is extremely dangerous and can become fatal if not treated immediately.

Symptoms:

High body temperature
Confusion
Disorientation
Dry hot skin
Collapse
Difficulty speaking
Seizures
Unconsciousness

Immediate medical attention is necessary.

The Mayo Clinic guide on heatstroke explains that untreated heat stroke can damage the brain, kidneys, muscles, and heart.

3. Dehydration

Drink enough water in summer

Many people remain chronically dehydrated during summer without realising it.

Signs:

Dry mouth
Dark urine
Fatigue
Constipation
Acidity
Dizziness
Reduced urination
Brain fog

Children and elderly people dehydrate much faster.

You can also read the National Institutes of Health (NIH) article on hydration and body function for a deeper understanding of how dehydration affects multiple organs.

4. Acidity, Gastritis and Digestive Disturbances

Digestive problems due to summer heat

Heat weakens digestion and increases inflammation in the stomach lining.

This may lead to:

Hyperacidity
Burning sensation
Bloating
Acid reflux
Loose motions
Loss of appetite

People consuming excessive tea, coffee, spicy food, fried food, alcohol, or irregular meals are especially vulnerable.

5. Migraine and Headaches

Heat related migraine and headaches

Summer headaches are extremely common.

Triggers include:

Dehydration
Bright sunlight
Sleep disturbance
Heat exposure
Stress
Skipping meals

People already prone to migraines often experience severe aggravation during heat waves.

The American Migraine Foundation on heat-triggered migraines explains how heat and dehydration can precipitate severe migraine attacks.

6. Blood Pressure Fluctuations and Heart Strain

Extreme heat places extra stress on the cardiovascular system.

This can cause:

Palpitations
Sudden BP fluctuations
Fatigue
Breathlessness
Increased risk of heart problems in vulnerable individuals

Elderly people and patients with hypertension should be particularly cautious.

The American Heart Association heat and heart health advisory warns that excessive heat significantly increases stress on the heart and circulation.

7. Skin Disorders and Allergies

Summer heat can trigger:

Fungal infections
Heat rashes
Urticaria
Eczema aggravation
Psoriasis flare-ups
Excessive itching

sweating creates ideal environment for infections

Sweating and humidity create an ideal environment for skin irritation and infections.

8. Mental Fatigue, Anxiety and Irritability

fatigue

Very few people connect heat with mental health changes.

Research shows that excessive heat can increase:

Irritability
Anxiety
Aggression
Emotional instability
Poor sleep
Fatigue
Brain fog

overheating strains the body’s systems

When the body is overheated, the nervous system becomes strained. Sleep quality drops, stress hormones increase, and emotional tolerance decreases.

Children often become:

More irritable
Hyperactive
Emotionally reactive

Adults may experience:

Low patience
Exhaustion
Emotional burnout

The American Psychological Association on climate and mental health highlights the psychological impact of prolonged extreme heat.
