Hot Weather

In normal weather, the body’s internal thermostat produces perspiration that evaporates and cools the body. Extreme heat and high humidity, however, slows down evaporation, forcing the body to work extra hard to maintain a normal temperature, potentially leading to heat cramps, heat exhaustion, and heat stroke. 

  • Avoid strenuous activity on hot days.

  • Drink plenty of water. Even if you do not feel thirsty, stay hydrated.

  • Wear lightweight, loose-fitting, and light-colored clothing. Light colors reflect sunlight and help maintain normal body temperature.

  • Protect your face with a wide-brimmed hat.

  • Too much sun is harmful. Use sunscreen with a high SPF rating when outdoors.

  • Cool off at one of the City’s many pools or water spray stations.

  • Go indoors to beat the heat, such as air-conditioned community centers, schools, libraries, or theaters.
  • If your home does not have air conditioning, try to stay on your lowest, coolest floor.

  • Use electric fans to cool you down, even if they do not cool the air.

  • Cover windows that receive morning/afternoon sun with drapes, shades, or awnings. Outdoor awnings can reduce the heat that enters a home by up to 80%.

  • Check on family, friends, and neighbors to make sure that they are safe.

  • Never leave children or pets alone in a closed vehicle.

  • Do not leave pets outside for extended periods, and give them plenty of water to drink.

If you believe you or someone you’re with is experiencing a heat-related medical emergency, promptly call 9-1-1. For non-emergency questions about the City’s heat-related services, please call the Mayor’s 24-Hour Hotline at 617-635-4500.
