How to Protect Yourself.
Drink plenty of fluids, stay in an air-conditioned room and stay out of the sun.
And check on elderly relatives and neighbors. Wear light weight and loose fitting clothing when possible.
Never leave small children or pets unattended in vehicles. Temperatures inside the vehicle can rapidly climb to 130 degrees.
When possible, reschedule strenuous activities to early morning or evening. Know the signs and symptoms of heat exhaustion and heat stroke.
To reduce risk during outdoor work, the Occupational Safety and Health Administration (OSHA) recommends scheduling frequent rest breaks.
Anyone overcome by heat should be moved to a cool and shaded location. Heat stroke is an emergency — call 911.
Here are our favorite places to stay cool in McLean. Please let us know yours.
1. Dolley Madison Library. Our top choice. Very cool. Great view, soothing view of the woods. Comfortable chairs and desks. Lots of nooks where you can curl up. The comfy chairs come with cup holders.
2. Tysons Corner Mall is open from 10 a.m. to 9:30 p.m.
Especially the movie theaters: The crowds are now a little smaller for local showings of summer blockbusters, but may swell again when Batman opens next week. See showtimes for the AMC Theaters at Tysons for information.
Or, just sit in the mall. There is a great sitting area just outside Macy's on the first level. Starbucks is adjacent. Just sip and people watch.
3. Tysons Galleria is open from 10 a.m. to 9 p.m. This is the Fifth Avenue of McLean. There's a great Starbucks on the first level.
4. Starbucks in Chesterbrook. This is McLean's best Starbucks. Cool temperatures. It's two levels, spacious and airy, and larger than the one in downtown McLean.
