Smart bed maker Eight released the first edition of the National Sleep Trends Report, which studied the impact of parenting on sleep. Titled “How Moms In America Sleep,” the research found that women with children experience greater sleep challenges than men with children including more frequent interruptions and trouble falling asleep. In families where children wake up in the night, mothers’ sleep suffers more than that of dads’ with their amount of deep sleep decreasing considerably.

Parents ages 25 and up living in the United States were surveyed about their sleep habits and patterns, and were asked to rate the quality of their sleep. Eight’s team analyzed these responses in correlation to the true sleep data collected from the company’s Sleep Tracker and Smart Mattress products, which measure over 12 sleep data points including sleep times, toss and turns, deep and light sleep, heart and respiratory rate.

The data showed that women sleep more than men, and the trend remains the same when they have children. However, according to the findings, moms are less likely than dads to report their sleep as good. Only 13% of moms said the quality of their sleep is “good” compared to 46% of dads. Moms frequently reported having trouble falling asleep, with 10% saying they have trouble “always” and 16% “often”—compared to 7% and 12% respectively for dads. Women with children also report getting up in the middle of the night more often than men with children.

Children waking up in the middle of the night impact the percentage of deep sleep that mothers get. A healthy person’s deep sleep range per night is 18% to 25%. Moms with children who wake up twice per night present a lower average than dads in the same situation: 21% to 24%. When children wake up every other night, moms deep sleep falls to 19% compared to 23% in dads. As a reference point, parents who report that their kids never wake up have very close percentages of deep sleep: 24% for moms, 23% for dads.

“Through our products we are discovering details and insights about sleep that no other company had been able to identify before,” says Matteo Franceschetti, CEO at Eight, in a release. “We believe that data holds the answers for most of our sleep problems, and analyzing this information is the first step towards identifying what products and solutions are needed. Our goal is to leverage this knowledge to help the 100 million Americans with sleep problems to improve their sleep and wellbeing.”

With the release of the first National Sleep Trends Report, Eight is looking to increase awareness of the current state of sleep in America by gathering insights for each segment of the population.
