Extreme heat and cold safety: what to do
Heat waves kill more people than any other weather hazard in many countries, and extreme cold brings frostbite and carbon monoxide risks.
What to do
- In extreme heat, drink water, stay in shade or air conditioning, and check on older neighbors.
- In extreme cold, dress in layers and limit time outdoors.
- Run generators and grills outdoors only. Carbon monoxide kills.
