New York may be the city that never sleeps but the Big Apple had better watch about because for the last 48 days Smashville has been sleepless and doctors said those late nights of playoff hockey can take a toll on your health.
"I think for the spectator you don't want to get too high and you don't want to get too low," said Dr. Bill Petrie a psychiatrist at Vanderbilt University.
Dr. Petrie is himself an avid Predators fans and says for fans, lack of sleep can become problematic especially over the prolonged period of time that the team has been in the playoffs for.
"Don't drink too much and I think when you've had as many games as we've have if your routine is to drink four or five beers during every game that's probably too many especially if you have three or four games a week," he added.
Fans who have been watching every game said they've noticed their heart rate increase during dramatic goals or controversial calls by reffs.
"My Apple watch tell me my heart rate has been going up, I knew it was up. It's like an adrenaline rush mixed with emotions. It's crazy," said Preds fan Adriana Valdivia.
