Heat-Related Illnesses: Prevention, Preparation, and Resources

Understanding Heat-Related Illnesses

Heat-related illnesses, such as heat stroke and heat exhaustion, are preventable with proper planning, education, and action. Heatgov serves as a valuable resource for information on heat and health.

Heat Advisories and Heat Risks

A heat advisory is issued by the National Weather Service (NWS) when dangerous heat conditions are expected. Local NWS offices establish their own criteria, often based on high heat index values. A heat advisory is typically issued within 12 hours of the onset of extremely dangerous heat conditions, with a general rule of thumb being when the maximum heat index exceeds a certain threshold.

NWS HeatRisk Index

The NWS HeatRisk is an experimental index that provides a color-coded risk assessment for potential heat risks based on local weather forecasts. Users can click on the map to access local heat risk information and NWS forecasts.

Heat Safety Tips

To prevent heat-related illnesses, follow these safety tips:

• Stay hydrated by drinking plenty of fluids.
• Avoid strenuous activity during the warmest hours of the day.
• Wear loose-fitting, light-colored clothing.
• Take frequent breaks in shaded or air-conditioned areas.
• Know the symptoms of heat-related illness and seek medical attention if necessary.

Heat-related illnesses are a serious health concern, but they can be prevented with proper precautions. By understanding heat advisories, heat risks, and safety tips, you can stay safe even during the hottest days of the year.
