Understanding Wet Bulb Temperature
Wet bulb temperature is a crucial environmental measure that combines heat and humidity to assess how the environment impacts the human body. Unlike the regular temperature readings found in weather apps, this measure provides a more accurate reflection of environmental stress on humans.
Impact of Humidity
- According to Dr. Sundar Krishnan, during periods of extreme humidity, the body struggles to cool due to inefficient sweat evaporation. This can make temperatures in the mid-30s feel dangerous.
- Risks:
- Dehydration
- Heat exhaustion
- Muscle cramps
- Dizziness
- Heatstroke in severe cases
- Warning Signs:
- Persistent fatigue
- Intense thirst
- Headache
- Nausea
- Confusion
- Rapid heartbeat
- Excessive sweating followed by dry skin
- Reduced urination
Vulnerable Groups
Dr. Harish Chafle warns that high wet-bulb temperatures are particularly dangerous for older adults, children, outdoor workers, and individuals with heart or kidney issues.
Measurement Techniques
- Traditionally measured using a thermometer wrapped in a wet cloth.
- Modern methods involve calculations using humidity, air temperature, wind speed, and atmospheric pressure.
Preventive Measures
- Maintain hydration and replenish electrolytes.
- Avoid outdoor activities during peak afternoon hours.
- Wear loose, cotton clothing.
- Stay in well-ventilated or air-conditioned spaces.
- Avoid direct sunlight.
- Use fans or air conditioning when possible.
Note: Always consult your health practitioner before starting any routine.
