Sort of like Goldilocks and the Three Bears, we don’t want too little or too much sleep. At 7 to 9 hours, it needs to be just right.
Where are we going? To the connection between the right amount of sleep and productivity.
Sleepless Famous People
In the daily schedule that Benjamin Franklin recorded in his 1791 Autobiography, he allocated approximately 7 hours to sleep:
For President Obama, the total is closer to 6 hours while Margaret Thatcher, President-elect Donald Trump, and Martha Stewart say that 4 hours of sleep are sufficient.
The Cost of Sleep
Maybe national leaders and CEOs are very different from the rest of us.
According to a Rand study that covered more than 62,000 UK workers, the U.S. GDP is 2.28% lower because we don’t sleep enough. Translated into workdays, the total is 1.23 million that we missed.
Curious about who sleeps less, you could look at a very long list in the Rand study. People with a long commute tend to have fewer sleep hours as do unmarried individuals. It also matters if you weigh too much and are male.
Here is a summary of some of the physical reasons that Rand cites:
