Symptoms of heat illness

If someone appears to be suffering from heat stroke, it's critical to call 911 immediately.

The NWS advises removing excess clothing, loosening garments, and using water or ice to help cool the person down.

Without proper treatment, heat stroke can cause permanent damage or even be fatal.

Signs of heat exhaustion include dizziness, intense thirst, heavy sweating, nausea, and feeling weak.

If you or someone else is showing these symptoms, move to a cooler place, loosen tight clothing, and slowly drink cool water.

If the condition doesn't improve, seek medical help, as heat exhaustion can progress into heat stroke.

Muscle cramps may also be an early warning sign of a heat-related illness.

Tips for heat safety

During extreme heat, the Baltimore City Health Department suggests staying well hydrated by drinking plenty of water while avoiding alcohol and caffeine.

Limiting outdoor activities and spending time in air-conditioned spaces can help reduce the risk of heat-related illnesses.

Residents are also urged never to leave children or pets unattended in closed vehicles, even for a short time, as temperatures inside can rise dangerously fast.

Additionally, checking in on elderly or ill neighbors is encouraged, as they may need extra assistance coping with the heat.
