Morning Naps May Signal Underlying Health Issues, Study Finds
Daytime naps have always had a bit of a good reputation. A quick nap can feel like a reset button, especially as we get older. But a new study is now suggesting that for some older adults, those extra daytime naps might be less about rest and more about what the body is trying to say.
Researchers from Mass General Brigham and Rush University Medical Center tracked more than 1,300 adults over nearly 20 years, looking closely at their daytime sleep habits. Their findings, published in JAMA Network Open, show a clear pattern: people who nap more often, nap longer, or nap earlier in the day tend to have higher overall mortality rates.
Now, before anyone swears off naps completely, there’s an important detail here. Napping is not the cause of health issues, but the frequency of it could signal that something else is going on.
Think of it like this. If someone who’s always been active suddenly starts needing long naps every morning, that change might be worth paying attention to.
The study used wearable devices to track when people were napping and for how long, which gives it a bit more weight than older research that relied on people guessing their own habits. Over time, researchers noticed that every extra hour of napping was linked to a 13 percent increase in mortality risk. Each additional nap added about 7 percent. And here’s the part that stood out: people who tended to nap in the morning had about a 30 percent higher risk compared to those who stuck to a short afternoon nap.
So what could be behind that?
According to the researchers, excessive napping is often tied to underlying health issues. That could mean chronic conditions like heart disease or diabetes, sleep disorders that mess with nighttime rest, or even early signs of neurological changes. In some cases, it may also reflect fatigue from inflammation or ongoing health stress in the body.

There’s also the timing factor. Morning naps seem to raise more red flags than afternoon ones. The thinking is that needing sleep that early in the day might point to deeper fatigue or disrupted sleep cycles. In other words, your body didn’t really get the rest it needed overnight.
That said, napping itself is not the villain here. Plenty of older adults nap regularly, and in many cases, it’s completely normal. Experts often say that a short nap, around 15 to 30 minutes in the early afternoon, can actually be beneficial. It’s when naps get longer, more frequent, or start creeping into the morning that they become something to watch.
There are also a few caveats. The study mostly followed older adults from a specific group in the U.S., and it didn’t account for things like nap quality or lifestyle differences across different populations. So while the findings are strong, they are not the final word.
Still, the bigger takeaway feels pretty practical. Changes in sleep habits, especially later in life, can offer clues about overall health. And now that wearable devices can track these patterns more accurately, doctors may have a new tool to catch potential issues earlier.
