NASA's research in the 1980s revealed that strategic napping could significantly enhance alertness and productivity, especially for astronauts facing erratic sleep patterns in orbit. The concept of "power naps" originated from efforts to improve pilot safety during long flights, with findings suggesting that napping early in a flight was most effective. Interestingly, the term "power nap" was coined to resonate with the alpha male culture of pilots, moving away from the less appealing "prophylactic napping."
