Hard work has long been the bedrock on which the American dream was built. But when hard work gets in the way of sleep, research suggests, it might just have the opposite effect. Sleep is slowly becoming a luxury good in the U.S., and a lack of it might affect not only how tired someone feels, but also that person’s income, health, and family life.
“If we aren’t fully rested, we are irritable, our motor skills are impaired, and we may not be able to make sound decisions,” said Bill Fish, a certified sleep science coach and co-founder of Tuck. “The labor market is competitive. Going into a job, or even to excel at a job, you have to be at your best. You aren’t [there] if you are not getting the recommended seven to nine hours of sleep on a nightly basis.”
According to Christine Spadola, a professor studying sleep and mental health at Florida Atlantic University, “We really do not have enough research to say that sufficient sleep can cause better financial outcomes. However, we do know that adequate sleep can be associated with higher productivity, increased concentration, and better academic functioning — all of which can be associated with better financial outcomes.”
The Center for Disease Control and Prevention (CDC) recommends that adults ages 18-60 should get at least 7 hours of sleep per night. However, the CDC reports more than 35 percent of the U.S. population gets less than that. Sleeping less than the recommended amount is associated with a wide range of health problems, from heart disease and mood disorders to diabetes and obesity. Similarly, data from the CDC 500 Cities project shows a strong correlation between sleep and self-reported physical and mental health, as well as physical activity and weight, according to a Haven Life analysis.
At the national level, 11.5 percent of the population suffers from poor physical health, 11.9 percent from poor mental health, 23.7 percent from a lack of physical exercise, and 29.5 percent from obesity, according to a Haven Life analysis of the CDC data. At the city level, as sleep habits dip below seven hours and household incomes decline below the national median of $60,336, these negative health metrics are more likely to increase.
In addition to the effects on the individual, sleep deprivation affects the family too. Research shows that it takes more than six years for first-time parents’ sleep routines to return to normal, pre-parenting levels. This is noteworthy given that parental sleep deprivation can influence childhood development, from infancy through adolescence. In addition, those who suffer from a lack of sleep might also struggle with key behaviors needed for effective parenting.
When asked how parents should prioritize sleep among other responsibilities, Spadola said, “In order to help parents prioritize their sleep, I would first encourage parents to identify how proper rest makes them better caregivers. For example, proper sleep allows you to be more patient, present, productive, and overall healthier.” For new parents, Fish recommends, “The best course of action is to work with your partner to set up a plan … to ensure you both get the rest that your mind and body need.”
Interestingly, some parts of the country are more likely to suffer from sleep deprivation than others. To find which cities are the most sleep-deprived, Haven Life analyzed statistics from the Centers for Disease Control and Prevention’s 500 Cities Project and the U.S. Census Bureau’s American Community Survey. For each city — grouped into large, midsize, and small cities based on population — Haven Life looked at the percentage of adults who get less than seven hours of sleep per night.
The most sleep-deprived cities are largely found on the East Coast and in the Midwest. Additionally, all but two of the most sleep-deprived small, midsize, and large cities have a median household income below the national median. Here are the cities whose residents get the least amount of sleep:

Methodology
Health statistics are from the Centers for Disease Control and Prevention’s 500 Cities Project. Median household incomes and population statistics are provided by the U.S. Census Bureau’s 2017 American Community Survey 1-Year Estimates.
For each city, data points were selected based on their correlation with the percentage of the population sleeping less than seven hours per night. Only variables with a Pearson correlation coefficient greater than .4 or less than -.4 (at least a weak to moderate correlation) were considered.
Only cities with a population greater than 100,000 were included in the analysis. Cities were grouped into the following categories based on population:
- Large cities: more than 350,000 people
- Midsize cities: 150,000 – 350,000 people
- Small cities: 100,000 – 150,000 people
