Andrew Huberman performs jumping rope in the morning while getting sunlight in his eyes to set sleep and waking rhythms.

“I own a jump rope I love doing it in the morning while I get sunlight in my eyes. It's actually a protocol I picked up from Tim Ferris who mentioned 'cause listeners in my podcast know I'm like a broken record with get sunlight in your eyes even through cloud cover it's just sets your sleep rhythms and your waking rhythms of yada yada on and on.”
