In fact, I have considered one in case I just want to (for example) drive to a trailhead the night before for an early morning start, and catch some sleep in the car without setting up a tent and all.
In the US, I used to sneak away for a nap during lunch. It's amazing how much more energy I have in the afternoon.
I think naps should be encouraged by managers in American work places. For example, give a small bonus to people who take 15-30 minute naps. I know if I ever run a company, I'd have a nap policy and provide safe spaces for workers to nap. A long time ago, bosses discovered that coffee increased productivity. I don't see why 15-30 minute naps shouldn't be encouraged by bosses.
Most people are somewhat sleep deprived, whether it's insomnia, anxiety, long commute, parenting, etc. For me, if I didn't get more 7 hours of sleep the night before, my productivity is half of a normal day. A nap can boost a worker's productivity significantly for half a day. It's better than stuffing yourself with coffee, which is unhealthy and provides more of a nervous energy than productive energy in my opinion.
But.. there is the alternative theory of the "caffeine nap" a.k.a. "coffee nap" - that you have coffee just before your nap, and then the coffee's first effect (dilating blood vessels) helps you fall asleep before the second effect (increased alertness) kicks in.
you know what we need? business hammocks!
But some spare space, air beds, eye masks/ear plugs would do the trick.
By any chance you work at Globex Corporation?
