It was a great day to drink water and not a bad day to dump it on your head as the Big Apple baked on the first full day of summer.

So much for the old saying “Never let ’em see you sweat.”

“It’s like purifying my body, bringing out the impurities.  It’s making me sweat, like a hot sauna…it’s healing,” Annette Phillips-Hakeem told CBS 2’s Tony Aiello.

But the hot temperatures presented a danger to other people.

The ER director at Lincoln Medical Center said the very young and the very old are most at risk. Last year, heat related deaths in the city spiked to 31 from 10 the year before and just 2 in 2009. One sign someone is succumbing to the heat is confusion.

“Once your body starts to lose significant amounts of fluid, you’ll actually stop sweating.  So look for signs of dry skin, dry mouth,” Dr. Fernando Jara said.

There’s was also danger on the playground to the tender skin of young kids. Several are treated each year for serious burns from playground surface temperatures that can approach 200 degrees.

Doctors say eating fresh fruits and vegetables with a lot of water in them can help keep your internal temperature down.

“Try to eat a light meal before so the body is not taking a lot of energy to digest those foods,” said Dr. Lisa Ganjhu from St. Lukes-Roosevelt Hospital.

Mayor Michael Bloomberg also reminded New Yorkers that they have a place to go to escape the heat.

“We all think we’re tough and nobody thinks that this is a big deal, but sadly, every year, we have to re-learn the lesson that this is a big deal,” Bloomberg said. “One of the best ways to stay cool, if you’re talking to somebody without air conditioning, is to go to one of the city’s cooling centers.”

Nearly 500 cooling centers are now open throughout the five boroughs. Call 311 to find the location of a cooling center near you.
