I'm extremely lucky as I have an office with a door. Most days I take a very short nap. It can be as short as 6 minutes but I like it to be 12 to 18 minutes. I drink a 1/2 cup of coffee before I nap most days. After darkening my space, I sit upright in my chair, close my eyes and nap. I use a android timer app and can glance at it with it if needed. I do find that most days I go out for a few mins, glance at the timer, out again till I get the amount I need in. I can turn around to my desk and be productive almost instantly after that short break.

My workspace nap time is usually between 1:30PM and 3:00PM.

On some days when I can't nap or don't I am foggy for the rest of the work day. On days when I nap this feeling is gone.

I 63 years old and love naps anyway. On the weekend I can nap in the corner of the couch for 20 to 30 mins sitting up. I used to be a road (plane) warrior and traveled for work 45 to 50 weeks a year. I had to learn to sleep wherever, like airports, on the plane, etc. So now I can sleep anywhere most days.

For example if I go to the doctor's office and have a long wait I can tap a nap if my body says it wants one.

My team is a team of 2 and they work in an open space outside of my door. They seem to like it a lot but they respect each others need to be quiet.

We work with another dev/creative team that is in an open office and is 8 people and they hate the open space. Everyone has headphones on but phone calls and visitors disrupt the quiet. Sometimes one of them comes to my open space and sits at one of the tables to get some quiet time in.
