How Can Caffeine Influence Your Sleep?

Coffee shops all over the country today are celebrating National Coffee Day with giveaways, deals and discounts. From Dunkin Donuts two-fers to free cups at Krispy Kreme, your Saturday is likely to be a caffeinated one. All the hype got us thinking — how does our caffeine obsession affect our sleep?

To find out more, we asked Eight sleepers how much and when they consume caffeine during the day. We correlated the responses to over 3,500 nights of sleep data from our Smart Mattresses and came up with some pretty interesting answers. Here’s what you should know about caffeine and sleep:

More coffee equals less sleep.

People lose 23 more minutes of sleep when they drink 4-6 servings of caffeine during the day compared to 1-2 servings. That may seem insignificant on a nightly basis, but if you regularly drink 4-6 servings, you could be looking at 6 full days of sleep loss yearly.

Drinking coffee in the morning affects your sleep less.

Users who drink their last cup of jo before noon sleep, on average, 20 minutes more than users who guzzle caffeine in the afternoon. Maybe you’re willing to lose those precious Zzzs, but you’ll likely be missing multiple sleep cycles in that time.

Coffee close to bedtime will delay sleep onset.

When you drink coffee in the afternoon, you’ll take, on average, 10 more minutes to fall asleep than if you only drink it in the morning.

Whatever your caffeine drinking habits are, we encourage you to enjoy National Coffee Day responsibly.

All the best,

The Eight Team
