Forty-two percent of Americans start feeling tired as early as noon, according to new research.

The survey looked at the daily habits of 2,000 Americans and found 65% said they rarely wake up feeling rested and energized.

And this daytime tiredness negatively affects 74% of respondents’ productivity.

Conducted by OnePoll on behalf of sleep and circadian rhythm supplement maker RestoreZ, the survey found that nearly half of respondents point the finger at not sleeping enough, closely followed by not sleeping deeply enough.

And when respondents don’t get enough sleep they’re left feeling out of focus and unmotivated.

Nearly half of respondents also said a lack of sleep puts them in a bad mood, while three in 10 admitted to getting snippy and losing their patience.

A quarter of respondents even said a lack of sleep contributes to poor decision making.

And 64% of respondents said they have trouble sleeping when their daily routine is thrown off.

Having a solid nighttime routine is crucial for 83% of those surveyed to properly wind down the day. Over half watch TV as they start getting ready to head to bed. Other parts of respondents’ nighttime routines included taking a bath or shower and checking to make sure their doors are locked. Thirty percent of respondents wind down for the night by meditating or exercising.

Despite these routines, however, only 37% of respondents are dedicated to a consistent sleep schedule where they go to bed and wake up at the same times every day.

A quarter of those surveyed even said their bedtimes and wake up times vary on a daily basis.

“Most people who are tired during the day and who wake feeling unrested think they have a sleep problem, but really they have a circadian rhythm problem,” says Jennifer Cooper, chief scientific officer at RestoreZ, in a release. “Our modern lifestyle is at odds with century-old programming built into our DNA that is designed not just to synchronize our sleep patterns, but also coordinates many other important functions in the body. One of the most important things we can do to strengthen our innate circadian rhythm is to have a bedtime routine that includes going to bed and waking up at approximately the same times each day.”

With this lack of consistency, it’s not surprising that 27% of respondents have trouble falling asleep and 34% have trouble staying asleep.

To remedy their sleep issues, 28% of those surveyed said they’ve tried herbal remedies and 26% have turned to over-the-counter medications.

Twenty-three percent of respondents also said they’ve tried melatonin and even prescription sleep medication in the hopes of improving their sleep.
