Why do we get dehydrated at night?
Dehydration during sleep occurs due to a combination of factors related to bodily functions and our sleep environment. During the night, our bodies continue to lose moisture via processes like respiration and perspiration, even though our activity levels and fluid intake are significantly reduced.
The humidified air we exhale can lead to water loss, especially in dry or air-conditioned environments. Individuals who snore or suffer from sleep apnea may experience increased moisture loss through mouth breathing.
Lastly, the body’s natural circadian rhythm influences the release of antidiuretic hormone (ADH), which helps regulate urine production. ADH levels typically drop during sleep, leading to increased urine output and potential fluid loss.
All these factors combined can result in a state of mild dehydration by morning, underscoring the importance of hydrating properly before bedtime and staying hydrated throughout the day to support overall health and sleep quality.
