I think I’ve talked about napping before. It’s supposed to be good for your heart and brain. But anyway, here is what a (paywalled) Philadelphia Inquirer article says are best practices.

• 20-30 minutes in length
• end 4-6 hours before bedtime (this would be 4-6 pm for me)
• “create the right environment by napping in a quiet, comfortable, and dimly lit space”

The article actually suggests it is okay to use caffeine to fight off grogginess when waking up from an afternoon nap. But I don’t think a cup of coffee late in the afternoon would work for me. I think that is actually a great time for exercise. And we know that is good for our hearts and brains.
