Are you a napper? Unless you’re retired that may sound like a ridiculous question. When could you possibly fit in the time to doze off for even 20 minutes? I suspect there may be one or two of you who, although you are still working, have found a way to schedule a nap into your schedules. The rest of us must wait until we no longer have clinical responsibilities.

In my experience, you regular nappers seem to be the lucky few who have discovered the art of nodding off after lunch and waking up refreshed and ready to take on a full afternoon of patients. We in the unlucky majority may have tried taking a nap but run the risk of its flowing into a deep slumber the length of which we can’t control. Or, more likely, we find that we wake feeling groggy and disoriented and, even worse, the daytime nod off has messed up our nighttime schedule.
Well, it turns out the ability to take daytime naps and reap their cardiometabolic benefits is not just luck but has a significant genetic component. Investigators at Massachusetts General Hospital in Boston have recently published a study in which they report finding more than a score of gene regions that determine a person’s propensity to take daytime naps.. The researchers have also unearthed preliminary evidence supporting a link between daytime napping and cardiometabolic health. My mother began napping when my sister and I were infants and never gave it up. Unfortunately, I seem to have ended up on the wrong side of the genomic shuffle.
Although this new research is interesting, I don’t think the investigators have enough information to answer one of the questions that every pediatrician fields multiple times each week. “When should my toddler grow out of his afternoon nap?” Although it looks like we may be getting closer to a gene-based answer, I have always couched my reply in terms of behavior modification and the fostering of habit-forming associations.
As a child begins to transition from multiple short naps interspersed with feedings to a pattern of two distinct naps, I suggest to parents that they begin to think of the afternoon nap as a siesta. In other words, the nap is something that always comes immediately after lunch with no intervening shenanigans. No playtime, no Teletubbies videos, no quick trips to the grocery store, nothing, nada, zip.
At least for me, lunch has always been soporific. And I suspect we will learn eventually that association cuts across the entire genetic landscape to one degree or another. It makes sense to take advantage of that association and remove all other distractions. For some parents, that means creating the illusion that they too are taking a siesta: No TV, no phone calls. Imagine that the whole household has suddenly moved to Spain for the next hour or two. If you’ve ever been a tourist in rural Spain and tried to do anything, buy anything, or visit a museum between 2 and 4 p.m. you’ve got the idea.
When the child is young he or she will probably fall asleep as long as his parents have been reasonably successful at maintaining sleep hygiene practices. As the child is gaining more stamina and gives up the morning nap, the siesta will remain as a quiet time because that’s the way it’s always been in the household. The child may sleep or play quietly, or be read a sleep-inducing story because no other options will be available until some predetermined time. An hour is usually reasonable. If sleep hasn’t overtaken them, an earlier bedtime will probably be in order. The child will outgrow the napping part of the siesta when his or her sleep need is gone. But, the siesta/quiet time can remain as an option until all-day school intervenes. This scheme works if you can get parents to appropriately prioritize their child’s sleep needs. That’s not always an easy sell.
