The Houston Department of Health and Human Services (HDHHS) urges everyone to take precautions to protect themselves from heat-related illness and death.

High-risk groups such as adults age 55 and older, children under the age of five and people with chronic illness are urged to stay inside air-conditioned buildings between 1pm and 5pm, the hottest part of the day.

Anyone without access to air-conditioning can seek shelter at any city facility. Houstonians may call 311 and ask for the nearest open city facility.

HDHHS recommends people take precautions against high heat and humidity to prevent illnesses such as heat exhaustion and heat stroke:

  • Increase water consumption. Drink lots of liquids even before getting thirsty, but avoid those with caffeine, alcohol or large amounts of sugar because these can actually result in the loss of body fluid
  • Conduct outdoor work or exercise in the early morning or evening when it is cooler. Outdoor workers should drink plenty of water or electrolyte-replacement beverages and take frequent breaks in the shade or in an air-conditioned facility
  • Check on the elderly. Take the initiative to visit seniors for signs of heat related illnesses. It takes the elderly nearly twice the time of younger people to return to core body temperature after exposure to extreme temperatures. A phone call to the frail elderly is not sufficient to determine physical condition
  • Wear light-colored, loose fitting clothing that permits the evaporation of perspiration
  • Do not leave children, senior citizens or pets unattended in a vehicle
  • A wide-brimmed hat helps prevent sunburn as well as heat-related illness. Sunscreen also protects from the sun's harmful rays and reduces the risk of sunburn
  • If the house is not air-conditioned, seek accommodations in air-conditioned facilities during the heat of the day: multi-service centers, malls, movie theaters, libraries, etc. Take frequent cool baths or showers if your home is not air-conditioned
  • Ensure that your pets are provided with shade and adequate water

Stay alert to heat advisories. The National Weather Service declares a Heat Emergency when the heat index, a computation of the air temperature and humidity, reaches 108 degrees on two or more consecutive days. A heat index of 108 is a potential health threat for all people and is particularly dangerous for high-risk groups.

During an excessive heat advisory, utility companies are prohibited from disconnecting service due to lack of payment.
