Do You Have Sleep Apnea and Not Know It?

You sleep seven or eight hours. You exercise. You eat reasonably well. You don't feel particularly tired during the day.

So how could you possibly have sleep apnea?

You could—and never know it.

Sleep apnea isn't limited to people who are overweight, chronically exhausted, or obvious loud snorers. Breathing disruptions during sleep can repeatedly interrupt your sleep architecture and place stress on your cardiovascular and nervous systems without fully waking you up.

And that's what makes it so easy to miss.

The Signs Aren't Always Obvious

The classic warning sign is loud snoring, especially when accompanied by pauses in breathing or gasping.

But there are subtler clues.

Do you regularly wake up in the middle of the night with a racing heart or a sudden feeling of anxiety? Do you wake up with a dry mouth or morning headache? Are you getting seven or eight hours of sleep but still feel like you didn't really recharge?

Even frequent nighttime trips to the bathroom can sometimes be associated with sleep apnea.

These symptoms don't prove you have apnea. But together, they can be reasons to investigate.

The problem isn't simply feeling tired the next morning. Repeated episodes of reduced breathing can cause intermittent drops in oxygen and repeated disruptions of sleep. Over time, untreated sleep apnea is associated with cardiovascular and metabolic problems, and researchers are investigating its relationship with cognitive decline and brain health.

What About the CPAP?

If you discover you have sleep apnea, don't assume your only option is a CPAP machine.

CPAP remains an important and highly effective treatment for many people. But depending on the type and severity of apnea, other approaches may be appropriate.

Mandibular advancement devices—custom dental appliances that gently reposition the jaw—can be an option for some people.

There are also approaches involving upper-airway muscle therapy, including specific exercises and newer stimulation devices.

The right treatment depends on the type and severity of your sleep-disordered breathing, so this isn't an area for trial and error on your own.

What Should You Do?

If several of these signs sound familiar, bring them up with your doctor or a sleep specialist.

You might ask:

“Could these symptoms be related to sleep apnea?”

A clinician may use a screening questionnaire such as STOP-BANG and determine whether a home sleep apnea test or an overnight sleep study makes sense.

And if you have a partner, ask them what they notice while you're sleeping. They may have information you simply can't observe yourself.

The Longevity Lesson

Don't judge the quality of your sleep by how long you're in bed.

You can spend eight hours in bed and still have fragmented, physiologically stressful sleep.

If you consistently wake unrefreshed, experience unusual nighttime awakenings, or have other signs of disrupted breathing, don't simply accept it as “getting older.”

Sometimes the most important thing you can do for your longevity is discover what's happening while you're asleep.
