We talk endlessly about caffeine, alcohol, and sleep—but what about plain old water? In this episode, we will:
- Dive deep into the fascinating relationship between hydration and sleep quality
- Explore how dehydration disrupts sleep architecture—raising heart rate, cortisol, and even airway resistance
- Learn how hydration supports thermoregulation, helps maintain slow-wave sleep, and prevents the dry-mouth awakenings familiar to CPAP users and frequent flyers
- Break down the latest research, from studies showing that short sleepers have higher urine osmolality
- Find out strategies for timing and optimizing hydration for better nights
