A heat wave has hit the Santa Clarita Valley and the surrounding areas. Firefighters are advising locals to beat the heat and stay safe with some suggestions on what to do when temps hit over 100 degrees.

With a heat index above 100 degrees through Wednesday, according to the National Weather Service, Santa Clarita, Castaic, Val Verde, Agua Dulce and Gorman residents are cautioned to avoid external exposure, particularly outdoor physical activity.

Extreme heat increases the chances of getting a heat-induced illness. In the event of a heat-related disorder, it is important to know the symptoms and proper treatment, fire officials said.

Heat Cramps: Individual will contract muscle spasms. Move the person to a cooler location, gently stretch and massage the cramping region. Ensure the person is taking sips of cool water once every fifteen minutes.

Heat Exhaustion: Person may experience dizziness, nausea, and exhaustion. Their skin will be cool and pale. Treatment involves laying the person down in a cool area and providing them with small sips of water.

Heat Stroke: A potentially life-threatening condition and extension of heat exhaustion. The individual will likely not be sweating unless they recently completed a strenuous physical activity. Look for hot, red skin, a rapid, weak pulse, and shallow breathing. Call 911 immediately and move them to a cooler environment. Do everything possible cool their core body temperature, usually with wet clothes or in a cool bath. Provide the individual with small sips of water once every fifteen minutes.

These conditions can be life-threatening and dangerous. If you or someone you know is suspected of suffering from a heat-related disorder, do not hesitate to call 911.

While these conditions are extreme, there are several other simple ways to stay cool in the heat to avoid any incidents:

Cover windows that receive morning or afternoon sun with shades, awnings, or drapes. According to the L.A. County Fire Department, “outdoor awnings or louvers can reduce the heat that enters a home by up to 80 percent.”

Drink plenty of water.

Avoid alcohol and caffeine. They increase the likelihood of becoming dehydrated.

Spend the warmest parts of the day indoors (i.e. libraries, schools, offices, or malls).

Wear loose and light-colored clothing.

Wear a wide-brimmed hat that cuts down on sun exposure to the body.

Go to the pool.

Run through sprinklers.

Have a water balloon fight.

The L.A. County Fire Department also recommends taking additional caution when dealing with children and pets.

NEVER leave children or pets in an enclosed vehicle. This can be potentially deadly.

Ensure both your animals and children are well hydrated. Limit physical exertion during the hottest parts of the day, typically from noon to 3 p.m.

If you feel you or someone you know is suffering from a heat related disorder or severe dehydration, the L.A. County Fire Department recommends you call 911.
