Sleep is not just about feeling tired tomorrow.
In this episode, Stanford sleep researcher Dr. Martin Kawalski explains why sleep often gets harder after 50, why older adults do not simply “need less sleep,” and why getting the basics wrong for long enough may affect how well we age.
One of the biggest ideas from this conversation: sleep regularity may matter more than total hours. Martin explains why consistent sleep timing is linked to all-cause mortality, and why your body craves rhythm across sleep, meals, caffeine, training, travel, and daily life.
We also talk about chronotypes, deep sleep, REM sleep, wearables, melatonin, alcohol, late meals, cannabis sleep gummies, naps, jet lag, and sleeping with a partner.
This is a practical conversation about building a sleep rhythm that works in real life — without turning sleep into one more thing to obsess over.
