March is Sleep Month—Are you getting enough sleep?

March, the month Daylight Savings Time ends, is National Sleep Month. On Sunday, March 13th, when the clock springs ahead, already chronically tired Americans will lose another hour of sleep.

Did you know more than a third of Americans get less than seven hours of sleep a night? The resulting fatigue has been linked to a number of serious medical issues such as Alzheimer’s disease, hypertension and other ailments. It may cost America’s economy as much as $400bn a year, according to one study. Other countries are similarly sleepless. Consumption of alcohol and caffeine are partly to blame, as is exposure to phone and computer screens. 

Some quick numbers on the statistics of sleep from around the globe are below. Let them serve as your wake-up call - no pun intended - to prioritize your Zz’s. Sleep is an important part of health and well-being at every age.

Sleep statistics worldwide

More than 20% of the general adult population in the U.S. and Canada have reported experiencing insomnia (Sleep Research Society, 2012).

-62% of adults around the world say they don’t sleep as well as they’d like (Philips Global Sleep Survey, 2019).

National sleep statistics

The prevalence of sleep disorders in the United States is so high that the CDC declared insufficient sleep a public health problem. Here are some national statistics on sleep loss in the U.S.:

-70 million Americans have chronic sleep problems (CDC, 2017).

Men and women each have their fair share of sleeping problems. In fact, one sleep survey found that 30% of respondents reported that they would like to file for a “sleep divorce” (in other words, sleep separately from their partner).

Between 9% and 21% of women have obstructive sleep apnea (ASA, 2021).

-Between 24% and 31% of men have obstructive sleep apnea (ASA, 2021).

How much sleep should you get?

Not getting enough sleep can be bad for your physical and mental health and cause some unwelcome symptoms. Not meeting your sleep needs can cause a lack of energy, trouble remembering things, a reduced attention span, slowed thinking, a reduced sex drive, poor decision making, irritability, daytime sleepiness, and other mood changes.

The exact amount of sleep you need will depend on your age, but in general, children need more sleep than adults to support their growth and development. Here’s a helpful guide from the Centers for Disease Control and Prevention (CDC) on the recommended amount of sleep that someone should get based on their age: 

0-3 months 


4-11 months 


1-2 years old 


3-5 years old 


6-12 years old 


13-18 years old 


18-64 years old
