How to Stay Cool During the Summer in Austin

Finding ways to beat the heat in Austin is very important to keep you from experiencing heat exhaustion and to keep your cooling bills down. 

There are several things to do during the summer months in Austin not only to stay cool, but healthy as well. 

  1. Drink lots of water. It is best to avoid things like caffeinated drinks and alcohol, as both of these can dehydrate you further. 
  2. Wear loose-fitting clothing. This allows air to circulate beneath the fabric and cool you off. 
  3. Don’t over-exercise. Exercise increases body heat all on its own. Be sure to take lots of breaks to rest and rehydrate.  
  4. Avoid using your oven. Turning the oven on can dramatically increase the temperature inside your home, causing your AC unit to work even harder.
  5. Air dry your dishes and clothes. Like an oven, both dishwashers and dryers will warm your home and could increase your cooling bills.

The tips listed above will help keep you as comfortable as possible in Austin’s extreme summer heat.
