if possible, take water to those who are vulnerable.
Take extra precautions when outside. Wear lightweight and loose
fitting clothing. Try to limit strenuous activities to the early
morning or evening. Take action when you experience symptoms of heat
exhaustion and/or heat stroke.
Beat the heat and check the backseat! Do not leave young children or
pets in unattended vehicles. Car interiors will reach lethal
temperatures in a matter of minutes.
