WHAT TO DO IN A HEATWAVE
A heatwave is a period of excessively hot weather, which may be accompanied by high humidity. A heat wave is a period of unusually hot weather. A heatwave is a period of prolonged abnormally high surface temperatures relative to those normally expected. Heat waves may span several days to several weeks and are significant causes of weather-related mortality, affecting developed and developing countries alike.
CAUSES OF HEAT WAVE:
Heat waves are caused by a strong high pressure settling in at 10,000-25,000 ft. and refusing to move. This causes warm air to sink. The result is a dome of hot air that traps the heat near the ground and prevents cooling convection currents from forming clouds. Heat also causes an increase in blood flow to the skin and pooling of blood in the legs, which can lead to a sudden drop in blood pressure. There can be a feeling of light-headedness before fainting occurs. Heat exhaustion – this is a serious condition that can develop into heatstroke.
EFFECT OF HEAT WAVE:
Rapid rises in heat gain due to exposure to hotter than average conditions compromises the body's ability to regulate temperature and can result in a cascade of illnesses, including heat cramps, heat exhaustion, heatstroke, and hyperthermia.
TIPS TO STAY COOL :
- Stay in an air-conditioned place as much as possible.
- Wear appropriate clothing: Choose lightweight, light-colored, and loose-fitting clothing.
- Don't use an electric fan when the indoor air temperature is over 95°F. ...
- Use your stove and oven less.
PREPARE FOR A HEAT WAVE :
1. Wear loose, lightweight, light-colored clothing.
2. Use your oven less to help reduce the temperature in your home.
3. If you're outside, find shade. ...
4. Drink plenty of fluids to stay hydrated.
5. Avoid high-energy activities or work outdoors, during the midday heat, if possible.
The signs of heat exhaustion :
• a headache.
• dizziness and confusion.
• loss of appetite and feeling sick.
• excessive sweating and pale, clammy skin.
• cramps in the arms, legs, and stomach.
• fast breathing or pulse.
• a high temperature of 38C or above.
