JJ Virgin argues sleep is the foundation for fat loss, muscle, and immunity. One bad night raises cortisol and hunger hormones while tanking serotonin. She recommends 7-9 hours, a cool dark room at 68°F, no screens an hour before bed, and a consistent bedtime routine.

Questions this episode answers

7–9 hours (average cited ~8 hours 15 minutes).

Within 30 minutes.

About 68 degrees Fahrenheit.

About three hours before bedtime.
