• Consume plenty of fluids to stay hydrated.

• Stay in an air-conditioned room.

• Avoid direct sun exposure: Protect yourself and check on vulnerable 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.

• Exercise caution outdoors: If you work or spend time outside, take additional safety measures.

• Consider the timing: When possible reschedule strenuous activities to early morning or evening.

• Recognize warning signs: Know the signs and symptoms of heat exhaustion and heat stroke.

• Dress appropriately: Wear lightweight, loose-fitting clothing to stay comfortable.

To minimize risks during outdoor work, the Occupational Safety and Health Administration (OSHA) advises incorporating frequent rest breaks in shaded or air-conditioned areas.
