Not only can napping boost mood and well-being, but large studies have shown a link between regular napping and good heart health. An occasional daytime nap was associated with a 48 per cent lower risk of heart attack, stroke or heart failure.

The first part of the linked article has good advice on napping. Two points worth adding are 1) it takes some practice to learn how to nap well; and 2) knowing how to nap erases anxiety over nighttime sleep quality. I like the linked article because it describes not just short twenty minute naps but also longer ones. For the most part, if you system wants to fall asleep for 60 minutes at nine in the morning (and you have a schedule that allows that), let it do it. ABN
