Frequent Naps May Signal More Than Simple Fatigue

What if your daily nap is trying to tell you something?

A new study published in JAMA Network Open found that older adults who took longer, more frequent daytime naps, especially in the morning, were more likely to die earlier than those who napped less.

Before you swear off naps forever, researchers say the naps themselves may not be the problem. Instead, excessive daytime sleepiness could be an early warning sign that the body is struggling with underlying issues like poor sleep quality, lung disease, sleep apnea, heart problems, or chronic inflammation.

In other words: your body may be asking for more sleep during the day because something else is going on underneath the surface.

What the Study Found

Researchers followed more than 1,300 adults over age 56 for up to 19 years. Participants wore wrist devices that tracked their sleep and activity patterns throughout the day.

The results showed several clear patterns:

• People who took longer naps had a higher risk of death over time

• People who napped more often throughout the day also had a higher risk

• Morning nappers had a higher mortality risk than people who mainly napped in the early afternoon

• Day-to-day inconsistency in naps did not appear to matter much

Researchers adjusted for many other factors, including age, medical conditions, nighttime sleep quality, medications, and physical activity. Even after accounting for those variables, the association remained.

Why Morning Naps Stood Out

The timing of naps may matter more than many people realize. Researchers found that older adults who regularly napped in the morning had a higher mortality risk than those who primarily napped after lunch or later in the afternoon.

Why? Because most healthy adults are naturally more alert earlier in the day. Feeling exhausted enough to sleep in the morning could signal excessive daytime sleepiness, disrupted sleep cycles, or an underlying medical issue.

That does not mean every morning nap is dangerous. But if someone suddenly feels the need to sleep multiple times a day or struggles to stay awake during normal daytime activities, it may be worth paying attention to.

What This Could Mean for Lung and Sleep Health

Excessive daytime fatigue is common in several pulmonary and sleep-related conditions, including:

• Obstructive Sleep Apnea

• Chronic Obstructive Pulmonary Disease

• Chronic low oxygen levels

• Poor nighttime sleep quality

• Heart disease

• Chronic inflammation

The researchers specifically noted that untreated sleep apnea may be one reason some people experience excessive daytime sleepiness and increased health risks.

Many people assume being tired during the day is simply part of getting older. But persistent fatigue can sometimes be the body’s way of signaling that sleep quality, breathing, or overall health may need closer evaluation.

Naps Are Not “Bad”

It is important to keep this study in perspective.

A short daytime nap can still be healthy and restorative. In fact, brief early-afternoon naps may improve alertness, mood, and energy levels for many people.

Researchers are not saying naps cause illness or early death. Instead, they believe excessive or unusual daytime napping may act more like a symptom, a clue that something else may be happening beneath the surface.

What You Can Do

Pay attention to changes in your energy levels. If you suddenly feel more tired during the day than usual, or find yourself needing multiple naps daily, it may be worth discussing with your healthcare provider.

Watch for signs of sleep apnea, symptoms can include:

• Loud snoring

• Waking up gasping for air

• Morning headaches

• Dry mouth upon waking

• Feeling exhausted despite sleeping through the night

• Trouble concentrating during the day

• Prioritize better nighttime sleep

Simple habits can help improve sleep quality:

• Keep a regular sleep schedule

• Reduce screen time before bed

• Limit caffeine late in the day

• Stay physically active

• Create a cool, dark sleep environment

• Don’t ignore chronic fatigue

Persistent daytime sleepiness is not something people should simply “push through,” especially in older adults or those with chronic lung or heart conditions.

The Bottom Line

An occasional nap is normal. But according to new research, longer, more frequent, and especially morning naps may sometimes be the body’s way of signaling an underlying health issue.

For older adults, changes in daytime sleep habits could offer an early clue that something deeper, from sleep apnea to cardiovascular or pulmonary disease, deserves attention.
