Beat the Heat!

Summer + Texas =  Extreme HEAT!  So let’s understand what can happen to you.  During periods of high heat and humidity, evaporation is slowed, and the body must work extra hard to maintain a normal temperature.  Most heat disorders occur because a person has been overexposed to heat or has over-exerted themselves in these conditions. Older adults, children, and those who may be ill or are sensitive to environmental conditions may succumb to extreme heat.

Additionally, conditions that can induce heat-related illnesses include stagnant atmospheric conditions and poor air quality.  Consequently, people living in urban areas, like San Antonio, may be at greater risk from the effects of a prolonged heat wave than those living in rural areas.  Asphalt and concrete store heat longer and gradually release heat at night, which can produce higher night-time temperatures known as the "urban heat island effect."

To prepare for extreme heat, you should stay aware of upcoming temperature changes, identify persons around you who may be vulnerable to excessive heat and check on them often, and most importantly stay hydrated.  Never leave children or pets alone in closed vehicles, stay indoors as much as possible and limit exposure to the sun, eat a well-balanced diet, drink plenty of water even if you do not feel thirsty (avoid caffeine/alcohol), dress in loose-fitting and lightweight clothing, apply sunscreen, and do not over exert yourself.

With a little planning, you can beat the heat and have a safe and fun summer!  For more information, contact the UTSA Office of Emergency Management at or visit the UTSA Campus Alerts website at
