If you want to get ahead in life, then you’ll need to work hard, be disciplined, and sacrifice sleep. If you’re asleep, you’re not working, and if you don’t work constantly, you can never manage a successful company or create the art that will make you famous. It’s not just your success on the line, either. Your country’s economy is counting on you to be a productive member of society. Besides, there will be plenty of time to sleep when you’re dead.

If you’re thinking these old saws sound dull, you’re right, and the data agree with you. Insufficient sleep has been linked to a slew of health issues, such as obesity, hypertension, and heart disease. It can also cause mood disorders and is a main contributor to poor work-life balance.

Workers pay and pay often for their poor sleep habits, but since the best-known ailments of sleep deprivation are personal in nature, employers and society do little to properly incentivize good sleep hygiene. But according to a study by Rand Europe, sleep-deprived Americans will cost the United States economy up to $434 billion by 2020, and the tab gets larger after that.

Sleep pays for itself

Based on survey data from 62,000 people, Rand Europe created a bespoke macroeconomic model that stimulated the interactions of economic agents (workers, companies, governments, etc.). They ran the model through three scenarios, and the results for 2016, the year of the study’s release, were staggering.

The United States proved the biggest economic loser, with losses between $281 and $411 billion. Japan, Germany, Canada, and the United Kingdom were also modeled, and researchers estimated that all five countries lose “up to $680 billion dollars of economic output every year.”

Insufficient sleep has been linked to a slew of health issues, such as obesity, hypertension, and heart disease. It can also cause mood disorders and is a main contributor to poor work-life balance.

That’s the bad news. The worst news is that these economic losses increase slightly in magnitude over time, meaning we forfeit more every year we don’t devise solutions for our societal sleep deprivation. In 2020, the U.S. is estimated to lose between $299 and $434 billion. By 2030, the amount will be between $330 and $468 billion.

Invested properly, these amounts could easily fund tuition-free public colleges and provide health care coverage for uninsured families, with change to spare (or, you know, it could develop one-third of an F-35 fighter jet).

Productive postmortem

We lose more year after year because of how insufficient sleep drains productivity from the labor supply — namely, through lower productivity levels, negatively affected skill development, and higher mortality risks.

The study found that less sleep increased absenteeism (due to illness) and presenteeism (that is, being physically at work but mentally checked out). Workers who slept less than six hours a day averaged a 2.4 percentage point loss of productivity compared to healthy sleepers. That may not seem like much, but it adds up to 6 working days lost per year per sleep-deprived worker.

Expand that number across the U.S., and the country loses the equivalent of 1.23 million working days a year. Days that, once lost, are gone.

Insufficient sleep also drains talent from the labor supply by hindering the skill development of school children, preventing them from properly acquiring the skills necessary to grow their productivity once a part of the workforce.

Finally, the study looked at the link between sleep deprivation and death. Poor sleepers have a 13 percent higher mortality risk from all causes of death, including, but not limited to, health-related issues and accidents caused by drowsiness. The CDC cites drowsy driving as responsible for 72,000 crashes, 44,000 injuries, and 800 deaths in 2013 alone.

Workers who die particularly impact economic losses, as their removal from the labor supply doesn’t just affect the year they died. It also removes all their future productivity, as well as the productivity of potential future children.

Even if there is time to sleep when you’re dead, there isn’t time to do much else.

Make sleep a priority, not a luxury

Good sleep hygiene improves your health and work-life balance, so it is to your benefit, not just the benefit of your employer or the country’s economy, that you sleep and sleep well.

As such, it may be worth having a talk with your manager about how to properly address deficiencies that deprive employees of sleep. Remember, it’s not just about your health, but your ability to perform productively for your employer. 

Here are some tips to help you get a good night’s rest:

  • Rest up. The National Sleep Foundation recommends working-aged adults (26–64 years old) get between seven and nine hours of sleep a night. Less or more sleep may be appropriate depending on personal needs. Women, for example, need more sleep than men on average.
  • Figure out your circadian rhythm. Try to go to bed and wake up at times that feel natural to you (but still net you the hours you need). Once you find that rhythm, be consistent. Go to bed and wake up at the same time every day.
  • Don’t acquire sleep debt. Your weekend catch-up sessions will credit you a bit, but it’s usually not enough. Creating a consistent sleep schedule is the only way to stay in the black.
  • Don’t consume nicotine, alcohol, caffeine, or sugary drinks before bed. Alcohol may help you fall asleep faster, but it reduces rapid-eye movement, curbing the quality of your sleep.
  • Silence is golden. Your brain needs silence to recover from the day. Schedule your phone to be silent during your sleep hours, and try to fix any household intermittent noises that you can (looking at you, leaky faucet).
  • Be in balance. Your room should be neither too warm nor too cold. Your body has to work to maintain a regular temperature in extreme conditions, making it difficult to rest.5
  • Darkness, my old friend. Night lighting may not be very bright, but it is significantly more so than the natural light of the moon and stars. Remove LEDs from your room and block out street lighting to help regulate your sleep-wake cycle.
  • No screen time before bed. The blue light of electronic screens prevents your pineal gland from releasing melatonin. Melatonin helps reduce alertness and mellow you out. Without it, your brain stays alert and awake.
  • Stop the snooze cycle. Using a snooze button wrecks your pre-waking REM and blunts your morning brain.8 If you’re waking up tired, you need to adjust to get more sleep.
  • Stay healthy. Exercise will also help you sleep by burning off excess energy earlier in the day.

Of course, our jobs will often add stressors that put mental relaxation out of our control. Commutes, financial concerns, unrealistic deadlines, irregular hours, and our always-on work culture are all cited by the authors of the Rand Europe study as sleep deterring qualities of the modern work environment.

As such, it may be worth having a talk with your manager about how to properly address deficiencies that deprive employees of sleep. Remember, it’s not just about your health, but your ability to perform productively for your employer. As the study’s authors note, “Solving the problem of insufficient sleep represents a potential ‘win-win’ situation for individuals, employers, and the wider society.”
