• Seek cool shelter: Opt for an air-conditioned room to stay comfortable.

• Stay out of the sun, and check up on relatives and neighbors.

• Child and pet safety: Never leave young children and pets unattended in vehicles, especially when car interiors can reach lethal temperatures within minutes.

• Be mindful outdoors: Take extra precautions when working or spending time outside.

• Time your activities wisely: If possible, reschedule strenuous activities to early morning or evening when the heat is less intense.
