Appropriated precautions need to be taken if heading outdoor especially if exercising.

Some tips before heading outside:

  • Exercise in the early morning or late evening hours. When the heat index is over 90 our natural body cooling system which is to produce sweat doesn’t work as well when the humidity is high.
  • Wear loose, light-colored clothing and a hat.
  • Make sure to hydrate before going into the heat.
  • Only wear a mask if you are around a crowd of people. It is not recommended you wear one while exercising as it might make it harder to breathe and cause heat exhaustion. If you do wear one make sure its breathable and made out of cotton.
