The National Weather Service advisory indicates that the combination of heat and humidity will increase the risk for heat related health issues, especially for the elderly, those with chronic health problems such as lung and heart disease, those working outdoors and other heat sensitive groups of people.

Extra precautions should be taken for those working or spending time outside.  The National Weather Service suggests when possible to reschedule strenuous activities to early morning or evening, know the signs and symptoms of heat exhaustion and heat stroke, wear light weight and loose fitting clothing and drink plenty of water.

Seniors and those with chronic health problems or mental health conditions are at an increased risk.  Homes without air conditioning can be much hotter than outdoor temperatures.

Use air conditioning to stay cool at home or go to a place that has air conditioning.  Check on vulnerable friends, family members and neighbors. 

Anyone overcome by heat should be moved to a cool and shaded location.  Heat stroke is an emergency, call 911.
