Honored to be interviewed by @nytimes @TheAthletic for their feature on why NHL players are prioritizing #sleep optimization over #alcohol during the season.

Alcohol disrupts sleep quality, slows recovery, and affects next-day performance.

Thank you @FlutoShinzawa!

It was a great pleasure to take part in an interview for Novi list, where I emphasized that #sleep is not passive rest, but an active phase that, when optimized, enables #athletes to recover quicker and perform better.

😴 People sleeping <5 hours had the most erratic glucose readings
🌙 Going to bed after midnight worsened blood sugar control even if total sleep time was decent
🛌 Early bedtimes helped stabilize blood sugar
