(KFVS) - The American Red Cross is urging residents to take precautions against the heat.

According to the Centers for Disease Control and Prevention, about 400 Americans die each year due to summer's sweltering heat. In recent years, excessive heat has caused more deaths than all other weather events, including tornadoes, floods and hurricanes.

The Red Cross says everyone is at risk when temperatures rise above 90 degrees; and the elderly and the very young are most susceptible to heat and heat-related illnesses. Heat-related illnesses can cause serious injury and even death if unattended. Signs of heat-related illnesses include nausea, dizziness, flushed or pale skin, heavy sweating and headaches. People with heat-related illness should be moved to a cool place, given cool water to drink and ice packs or cool wet cloths should be applied to the skin. If a victim refuses water, vomits or loses consciousness, call 9-1-1 or your local emergency number immediately.

CALLOWAY COUNTY, KY (KFVS) - The Murray-Calloway County Hospital will host several support groups on Thursday, June 21.

Group meetings include:

(KFVS) - The 5th Annual National Walk@Lunch Day will be Wednesday, April 25.

National Walk@Lunch Day is created to improve personal health and decrease the costs of health care for employers and employees.

The goal is to make Nationa Walk@Lunch Day the start of a new daily walking routine for participants.

Participants are encouraged to bring or wear comfortable shoes and take a walk at lunch, rain or shine.

The U.S. Department of Health and Human Services estimates the cost to treat illness and chronic disease caused by inactive lifestyles in nearly $1,000 for every family in America, every year.

They say simply getting 30 minutes of moderate physical activity, such as a brisk walk at least five times a week, has significant health benefits, lowering the risk of developing or dying from cardiovascular disease, hypertension or type 2 diabetes, and improving the health of muscles, bones and joints.
