True fact – according to scientists, if you start the day immersing yourself in ocean water under 75 degrees Fahrenheit for at least 30 minutes it optimizes your body temp for the entire day similar to how breakfast optimizes metabolism throughout the day. This leads to better memory, greater concentration, increased energy, and reduced risk of heart disease, diabetes, and arthritis. The practical implication? Swimming at nantasket Beach at 6:30 or 8:00 (get inside lot by 7:45 to avoid parking charge) for an open water swim is like taking a dip in the fountain of youth.
