Dehydration and Sleep

Too Little Sleep Can Cause Dehydration

According to a study published by Penn State, adults studied in the U.S and China who regularly slept six hours or less per night were 16-59% more likely to be dehydrated than those who got eight or more hours of sleep. Researchers think that a hormone known as vasopressin, which helps regulate the body’s fluid balance, may be the link between too little sleep and dehydration. While vasopressin is released during both day and night, it’s known to be released more quickly and later in the night’s sleep cycle. So if someone isn’t getting those last precious hours of sleep, their body’s fluid balance gets disrupted.

Dehydration Can Happen Even With a Full Night’s Sleep

Sleep deprivation isn’t the only way to become dehydrated overnight. Even when you get your full 40 winks, a number of other factors—many of which are out of your control—can contribute to your body’s fluid stores being depleted. For example:

Snoring! People who breathe through their mouths during sleep and those with sleep apnea lose more fluids in the night than those who breathe through their noses while sleeping.
An overly hot or dry bedroom. While asleep, you may not even be aware that your environment is making you sweat. But your body is—and that extra perspiration means extra fluid loss.
A late exercise routine. An intense workout late in the evening or right before bed without enough hydration can mean waking the next morning dehydrated, as you couldn’t “listen” to your natural thirst response while you were asleep.
Lowered estrogen levels. For women in menopause or those in that portion of their regular menstruation cycle when estrogen dips, your chance of dehydration rises, as this hormone is linked to the body’s ability to retain fluids, during both day and night. And for menopausal women, the addition of night sweats— those severe hot flashes that can drench your pajamas and sheets—make the body’s fluid loss during sleep all too evident.
Medication side effects. Certain categories of medications are associated with dehydration at night, including antidepressants, antihistamines, as well as various blood pressure and heart disease medicines.

Regardless of the source of your nighttime dehydration, there’s a simple way to get those fluid levels back to where you need them for the day ahead—a glass of oral rehydration solution like DripDrop ORS in the morning. DripDrop ORS provides dehydration relief fast in delicious flavors - both hot and cold - and will help restore your fluid balance after a dehydrating night.
