#174 - Hydration and Sleep: It's In The Water

Sleep Unplugged with Dr. Chris Winter

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
