When Work and Sleep Conflict, Work Wins

nytimes.com - There are a lot of advantages to earning more money, but getting a good night’s sleep may not be one of them.

It turns out that, in general, the more money people make, the less they sleep. That’s been true for decades in the United States, and in other countries as well. On average, adults earning the highest incomes — around $98,000 for a family of four — sleep 40 minutes less than people in the lowest-income families. And among short sleepers — those who are in the bottom 10 percent of nightly rest — high-income people are overrepresented, according to the government survey that sleep researchers trust most.
