BOSTON (WBZ NewsRadio) — The warmer air temperatures may tempt you to take a dip in the ocean and nearest lake, but the National Weather Service is reminding residents to slow their roll and prepare themselves for a polar-like plunge should they take the dive.
The advisory comes as part of the NWS' "Cold Water Safety Awareness Week," which spans April 10 to Friday, 14.
WBZ's Brooke McCarthy spoke to NWS Meteorologist Kristie Smith, who said part of the preparation is mental.
"It's not a good idea to go swimming if you're not prepared for the shock of that cold water. People go out unprepared, especially without anybody knowing or without a buddy system, obviously [I] always recommend if you are going out on the water you bring a life jacket," Smith said.
According to officials, swimmers that jump into waters below 50 degrees Fahrenheit are at risk of "cold water shock," which can incapacitate and even cause heart failure in some. Smith goes on to say symptoms of cold water shock can come in the forms of gasping for air, increased confusion, and an elevated heart rate— all of which can set in less than a minute.

For waters a little warmer, in the ballpark of 60 degrees, incapacitation comes on typically around the ten minute mark with possible loss of feeling and muscle control in arms, legs, and fingers. With the water just below 70 degrees, the core body temperature drops to under 95 degrees, leading to potential loss of motor control.
Along with a life jacket, officials say dressing for the water temperature (not just the air temps) is a good idea. That could mean strapping on a wetsuit or dry suit, officials said.
