Tips to Prevent Heat-related Illnesses

Stay cool. Keep your body temperature cool to avoid heat-related illness.

  • Stay in air-conditioned buildings as much as possible.
  • Find an air-conditioned shelter.
  • Do not rely on a fan as your primary cooling device.
  • Avoid direct sunlight.
  • Wear lightweight, light-colored clothing.
  • Take cool showers or baths.
  • Do not use the stove or oven to cook.
  • Check on those most at-risk twice a day.

Stay hydrated. Because your body loses fluids through sweat, you can become dehydrated during times of extreme heat.

  • Drink more water than usual.
  • Don’t wait until you’re thirsty to drink more fluids.
  • Drink from two to four cups of water every hour while working or exercising outside.
  • Avoid alcohol or liquids containing high amounts of sugar.
  • Remind others to drink enough water.

Stay informed. Stay updated on local weather forecasts so you can plan activities safely when it’s hot outside.

NH Environmental Public Health Tracking

New Hampshire has a lot of nature to enjoy. There is a sea coast to swim and surf. There are mountains, lakes, and forests to explore. However, environmental dangers like radon, ultraviolet radiation, and climate change threaten the enjoyment of these natural resources. The New Hampshire Environmental Public Health Tracking (EPHT) Program is keeping track of these and other emerging environmental health threats in order to keep residents informed and protected.

Surveillance data is accessible through NH Health WISDOM and focuses on measures of health outcomes that are related to the environment, hazard data that tell us about pollutants that may be found in the environment, and exposure data that tell us about contaminants found in people's bodies.

Environment Data: Air Quality, Climate Change, Drinking Water Quality, and Radon.

Health Data: Asthma, Birth Defects, Cancer, Carbon Monoxide, Heart Attack, and Lead Poisoning.

Local Project Areas: Heat and Health, Neighborhood Health Indicators, Recreational Water Quality, Social Determinants of Health, and Tickborne Disease.

Policy makers and public health officials can use the Tracking Network to make critical decisions about where to target environmental public health resources and interventions. Health practitioners and researchers can use the Tracking Network to learn more about health conditions related to the environment, and improve treatment plans. Anyone can use the Tracking Network to find out how the environment may be affecting them, their family’s or community’s health.
