The National Weather Service of Wichita tweeted a warning Wednesday morning — ”be sure to limit outdoor activity in the afternoon and early evening.”

The reason comes from the service adding a day to a dangerous heart warning — head indexes could climb to as high as 110 degrees today, and remain above 100 through Saturday.

McPherson’s finest will still be on patrol and out in the heat.

“As officers go from call to call, in and out of their patrol cars, the heat can definitely take a toll on them if they are not hydrated,” said Mark Brinck, Administrative Captain/Public Information Officer with the McPherson Police Department.

And in addition to monitoring themselves, they are keeping tabs on the community as well.

“As always, our officers keep an eye out for anyone who looks like they may be in distress and will stop to lend a hand,” Brinck said

According to the U.S. Department of Health and Human Services, there is a high risk of “heat stress” during triple-digit high temperatures. There is also a risk of heat stroke, which can lead to serious health problems.

According to the Mayo Clinic, untreated heat stroke can quickly damage your brain, heart, kidneys and muscles. The damage worsens the longer treatment is delayed, increasingrisk of serious complications or death.

The clinic recommends staying in air conditioned buildings during the heat of the day — but if that is not available, drink plenty of fluids, taking breaks and knowing where medical attention can be given in the case of overheating.

“With the elevated temperatures we are experiencing now, and the uniforms, ballistic vests, and equipment our officers wear, it is extremely important that our officers stay hydrated, “ Brinck said.

Signs of the most severe heat-related illness, heat stroke, include a body temperature above 103 degrees; hot, red, dry or moist skin; rapid and strong pulse; and altered mental status, which can range from confusion and agitation to unconsciousness. If symptoms are present, call 911 immediately and take steps to cool the person.

Victims of heat stress may experience heavy sweating; weakness; cold, pale, and clammy skin; fast, weak pulse; and nausea or vomiting. Early signs include muscle cramps, heat rash, fainting or near-fainting spells, and a pulse or heart rate greater than 100.

According to the department, victims of heat stress should be moved to a cooler location to lie down. Apply cool, wet cloths to the body, especially to head, neck, arm pits and upper legs near the groin area, where a combined 70 percent of body heat can be lost; and have the person sip water. They should remain in the cool location until recovered with a pulse heart rate well under 100 beats per minute.

To help prevent heat-related illness:

• Spend time in locations with air conditioning when possible.

• Drink plenty of fluids. Good choices are water and diluted sport electrolyte drinks (1 part sport drink to 2 parts water) unless told otherwise by a doctor.

• Choose lightweight, light-colored, loose-fitting clothing.

• Limit outdoor activity to morning and evening hours.
