ORS (Oral Rehydration Solution) – A Key Health Solution to Prevent Dehydration During Summer

Introduction

During summer, increasing temperature poses a major challenge to human health. The normal body temperature is around 98.4°F, but when it rises due to external conditions, conditions like hyperthermia may occur. This can lead to dehydration, dizziness, and heat stroke. To prevent this, ORS (Oral Rehydration Solution) is considered a simple and effective solution.

Dehydration – Causes and Effects

During summer, the body sweats excessively.
This helps in reducing body temperature.
However, at the same time:
Water, glucose, sodium, potassium and other electrolytes are lost.
This leads to:
Kidney failure
Heart function issues
Dizziness and fatigue
Severe condition: Heat Stroke
This topic is related to TNPSC General Science (Health & Hygiene).

ORS – Composition and Function

The ORS formula recommended by the World Health Organization (WHO) includes:
Sodium Chloride (NaCl)
Glucose
Potassium Chloride
Trisodium Citrate

These help in the body by:
Maintaining fluid balance
Restoring electrolyte balance
Ensuring rapid absorption through the intestine

Usage:
Mix in 1 liter of boiled and cooled water
Use within 24 hours

Soft Drinks vs ORS

Some drinks marketed as “ORS” in the market:
Are medically ineffective
Do not contain proper levels of salts or glucose
Only real ORS:
Follows WHO standards
Effectively treats dehydration

Historical Importance

During the 1971 Bangladesh refugee crisis,
Dr. Dilip Mahalanabis used ORS
Saved thousands of lives
ORS is considered one of the most important medical discoveries of the 20th century.

Children and Public Health

ORS is essential for children with diarrhoea
So far, about 70 million children have been saved using ORS
It is considered a Public Health Intervention.

Implementation in Tamil Nadu

ORS centers in government hospitals and PHCs
Free distribution to the public
Preventive measures during summer
This is related to Health systems in Tamil Nadu (TNPSC syllabus).

Home Preparation of ORS

Water + Salt + Sugar
Correct proportion is very important
Incorrect ratio → harmful to the body

Conclusion

Although dehydration may seem like a common issue during summer, it can become life-threatening. ORS is a simple, affordable, and effective solution to prevent it. Public awareness, strengthening health systems, and following WHO standards are essential.
