In response to forecast heat (including temperatures of 90 degrees or higher all week in Kent), state health officials are issuing a health advisory and urging people to take precautions.

Groups at increased health risk from extreme heat include older adults (ages 65-plus), people with chronic medical conditions, young children and those who work or exercise in a high heat environment.

It’s important to visit older friends, relatives and neighbors to make sure fans or air conditioners are working and living spaces are ventilated. People who do not have air conditioning are advised to seek relief from the heat by visiting friends or relatives that have air conditioning.

A new system deployed by the state Department of Health using data provided by hospitals across Washington showed a significant rise in the number of people seeking medical treatment for illness and injury related to heat during the high temperatures experienced earlier this month.

The state Department of Health recommends that to avoid heat-related illness, people should follow some simple tips:

• Stay indoors and in an air-conditioned environment as much as possible, unless you’re sure your body has a high tolerance for heat.

• Drink plenty of fluids but avoid beverages that contain alcohol, caffeine or a lot of sugar.

• Eat more frequently but make sure meals are balanced and light.

• Never leave any person or pet in a parked vehicle.

• Avoid dressing babies in heavy clothing or wrapping them in warm blankets.

• Check frequently on people who are elderly, ill or may need help. If you might need help, arrange to have family, friends or neighbors check in with you at least twice a day throughout warm weather periods.

• Salt tablets should only be taken if specified by your doctor. If you are on a salt-restrictive diet, check with a doctor before increasing salt intake.

• If you take prescription diuretics, antihistamines, mood-altering or antispasmodic drugs, check with a doctor about the effects of sun and heat exposure.

• Cover windows that receive morning or afternoon sun. Awnings or louvers can reduce the heat entering a house by as much as 80 percent.

• Make sure pets have plenty of water.

The early warning signs of heat stress can include decreased energy, slight loss of appetite, light-headedness and nausea. People experiencing these symptoms should go to a cool environment, drink fluids, remove excess clothing and rest.

Serious signs of heat stress can include unconsciousness, rapid heartbeat, throbbing headache, dry skin, chest pain, mental confusion, irritability, vomiting, diarrhea, muscle cramps, staggering and/or difficulty breathing. People experiencing these symptoms should get immediate medical attention. While waiting for help move the person to a cool area, remove excess clothing, spray with water and fan the person. In an emergency, dial 911.
