The National Weather Service has issued an excessive heat warning, increasing the risk of heat related illnesses like heat exhaustion and heat stroke for those who are more sensitive to heat.
Prolonged exposure to excessive temperatures may cause serious conditions like heat exhaustion or heat stroke and can even be fatal. Symptoms of heat exhaustion may include heavy sweating, muscle cramps, weakness, headache, nausea or vomiting and dizziness. Warning signs of heat stroke may include an extremely high body temperature, unconsciousness, confusion, hot and dry skin (no sweating), a rapid, strong pulse, and a throbbing headache. If symptoms of heat stroke occur, immediately call for medical assistance. Move the person to a shady area and begin cooling their body with water.
Recommended precautions to prevent heat related illnesses include:
- Drink plenty of water; don’t wait until you are thirsty.
- Wear light, loose-fitting clothing.
- Stay out of the sun if possible, and when in the sun wear a hat, preferably with a wide brim, and use sunscreen.
- Avoid strenuous activities if you are outside or in non-air conditioned buildings. If you are working outdoors, take frequent rest and refreshment breaks in a shaded area.
- Never leave children, elderly people or pets unattended in closed cars or other vehicles.
- Check on those, like neighbors, who are at high risk to make sure they are staying cool – including seniors who live alone, people with heart or lung disease, and young children.
- Stay cool indoors.
In addition, California ISO has issued a Stage 3 electrical emergency with possible rotating outages during this excessive heat event. Energy experts are asking residents and businesses to use AC early in the day, pre-set thermostats to 78 degrees or higher and avoid appliance use from 3 – 10 p.m.
