Tips on how to deal with the hot weather, David Nuno reports. (KTRK)

The National Weather Service has issued heat advisories for Houston as temperatures are expected to stay high over the next few days. The advisory is in effect until Saturday.

Tips to guard against extreme heat from the Houston Health Department:
* Wearing loose-fitting, light-colored clothing if you're going to be outdoors.
* Drink plenty of water, and avoid caffeine and alcohol, as these can cause dehydration
* Conduct outdoor work, such as lawn care in the early morning or evening when it is cooler.
* NEVER leave Children, Seniors or pets unattended in vehicles
* Wide-brimmed hats help prevent sunburn as well as heat-related illness. Sunscreen reduces the risk of sunburn.
* If your home is not air conditioned, seek accommodations in air-conditioned facilities such as libraries, multi-service centers, malls , movies theatres, etc.
* Take frequent cool baths or showers if your home is not air conditioned
* Be informed about changing conditions. The National Weather Service usually 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.
