I've often wondered whether I'll sleep better at night if I don't take a nap. Some books say yes, others say no.
So I did a little study. For a month I recorded my nap duration and other data, and made note of how well I slept that night. Here's the data sheet:

Sleep quality is on a 0-10 scale. A 10 means I fell asleep quickly, didn't wake up during the night, and woke 8 or 9 hours later feeling wonderfully rested and refreshed. A 5 for example, could mean that I woke in the night and was awake for an hour, and/or woke up several hours early.
The key for exercise is: N=None, B=Bike, R=Run, S=Strength (weightlifting).
The alcohol refers to the number of glasses of beer (12 oz) or wine (4 oz).
The important discovery is that napping seems to make no difference to my sleep quality:

The spread (e.g. standard deviation) of these numbers is pretty high, so I'm confident that there's no significant difference between the quality for the different groups.
I was surprised to discover, that my sleep quality seems to go in waves. That is, I'll sleep well for a number of nights in a row, and then sleep less well (ignore the nap duration in this graph).

I've been too lazy to do any other analysis.
This is useful for me, since I can now be relatively confident that I can nap as much as I want without worrying that my nighttime sleeping quality will suffer.
