ZzzQuil, Nighttime Sleep-Aid Liquicaps - 48 Liquid caps

Get a beautiful night’s sleep with ZzzQuil™, from the makers of Vicks® NyQuil®. ZzzQuil is a non-habit-forming sleep-aid for the relief of occasional sleeplessness that helps you sleep soundly, so you can wake up feeling refreshed. ZzzQuil contains diphenhydramine HCI, which is a big word for a small compound that helps you sleep. Now you can add Zzz’s back to your night with ZzzQuil. 

For the relief of occasional sleeplessness, reduces time to fall asleep if you have difficulty falling asleep. • Non-Habit Forming. • Not for colds. Not for pain. Just for sleep. Sleep soundly so you can wake refreshed. • Not for treating cold or flu.

Although ZzzQuil is brought to you by the makers of Vicks NyQuil, it’s not for colds. It’s not for pain. It’s just for sleep. But how does ZzzQuil work—and how does it help you get the sleep you need?

ZzzQuil contains diphenhydramine HCI, which is a big word for a small compound that helps you sleep. To help you stay awake and alert, your body produces histamine, a naturally occurring substance that interacts with receptors in your brain to promote wakefulness. Diphenhydramine is an antihistamine, which blocks your brain’s alertness to make you feel the opposite: drowsy.

Studies have shown that diphenhydramine relieves occasional sleeplessness when used as directed by reducing the time it takes for you to fall asleep so you feel rested in the morning. Plus, diphenhydramine is non-habit-forming, which means that you can feel safe taking ZzzQuil as directed—to get a good night’s sleep and wake up feeling refreshed.

Why Do You Need Sleep?

There’s no simple answer for why we need the amazingly complex state our bodies fall into every night. Scientists do know that sleeping is not a passive activity—our bodies snooze while our brains keep busy processing information, consolidating memories, and conserving energy.1  And without sleep, the effects are immediate: Common indicators of sleep loss include mood change (irritability and general grumpiness), feeling inattentive, and a reduction in psychomotor performance.2,3     Image

Understanding Your Natural Rhythm

Your body has a natural 24-hour cycle called the circadian rhythm, which helps you to feel awake when it’s light out and sleepy when it’s dark.4  However, this natural synchrony can work against those who keep later hours or work night shifts in the current world. If travel, work, or an ever-changing schedule keep you up and active at night, be sure to get 7 to 8 hours of sleep—even if it’s during the day.5  Also try to keep to your night owl schedule, even on your days off.6  And if you’re suffering from jet lag after traveling, try to rest when your body tells you to. It can take several days for your body to adjust to your current time zone and return to your previously set circadian rhythm.5  

The Right Amount of Shut-eye

There is one sleep fact that most specialists can agree on: how much sleep you need to perform your best, both mentally and physically. While the answer varies a bit from person to person, the findings are fairly definitive: The average adult needs about 7 to 8 hours of sleep to function well and feel rested.7
