Yes, As Swimshark said in this thread especially if your older. Feelling a bit sick can occur if you dont cool off and its a common feeling, also more serious arrhythmias (abnormal heart beat) can occur with the heart beating fast for a period of swimming then the effort stopping suddenly. A cool off and slow down is a smart thing to do unless your a young well conditioned swimmer and just set a new world record and can jump right out of the pool looking at the time clock in amazement and excitement!
