Loud snoring isn’t the only symptom of sleep apnea. If you notice any of the following less obvious sleep apnea symptoms, talk to your doctor.

You’re sleepy all day
If you’re tired 24/7, don’t just chalk it up to a busy life. “A lot of people feel tired, but don’t know why and attribute it to lack of sleep, among other things,” says Boris Chernobilsky, MD, director of sleep and airway surgery at Mount Sinai Beth Israel in New York City. Daytime sleepiness is one of the most common symptoms of sleep apnea, but men with sleep apnea tend to report daytime sleepiness more often than women, says Dr. Chernobilsky. Both obstructive sleep apnea (muscles relax during sleep, causing soft tissue in the back of the throat to collapse and block the airway) and central sleep apnea (the brain fails to signal your body to breathe) lead to disrupted sleep. Patients wake up frequently throughout the night but they don’t always remember it. They just feel sleepy all day.
You wake up with a headache
If you start each day with a pounding head (and didn’t have one too many beers the night before), lack of sleep caused by sleep apnea might be to blame. Even if you did get the recommended seven to eight hours, sleep apnea disrupts your sleep. Shockingly, people with severe sleep apnea can awaken hundreds of times each night, according to the Stanford Center for Sleep Sciences and Medicine.
More nighttime trips to the bathroom
“Many people wake up in the middle of the night and don’t know why, so they’ll think maybe it’s because they need to pee,” says Dr. Chernobilsky. Though that may sometimes be the case, many patients are just searching for the reason they’re awake and don’t actually have the urge to go, he says.
You’re irritable or have mood changes
Lack of sleep may be the reason for your newfound irritability, not the fact that you have a case of the Mondays. Changes in mood, as well as increased stress and anxiety can be a silent sign of sleep apnea; studies have shown that people who don’t get enough sleep report feeling more stressed, angry, sad, and mentally exhausted, according to the Division of Sleep Medicine at Harvard Medical School.

Your driving is getting worse
“One of the biggest signs of sleep apnea is car accidents,” says Dr. Chernobilsky. In fact, a 2015 study in the journal SLEEP found that people with sleep apnea were 2.5 times more likely to be the driver in a car crash than people without the disorder. Researchers said in a news release that extreme daytime sleepiness and getting less than five hours of shuteye were to blame for the dangerous distracted driving. In the same study, car accidents were reduced by 70 percent among sleep apnea participants who used the common treatment of continuous positive airway pressure (CPAP) therapy at night.
Weight gain for no apparent reason
While you’re snoozing away, your hormones are hard at work, with those that regulate hunger functioning at very specific times throughout your sleep cycle. “When you disturb the natural circadian rhythm, some hormones don’t reach their peaks or get released at all,” says Dr. Chernobilsky. That means you may feel hungrier throughout the day and even become more insulin resistant, he says, which can eventually lead to diabetes.
Trouble being intimate
“Impotence is a big sleep apnea sign for men. Many blame it on low testosterone or stress, but sleep apnea can be the cause,” says Dr. Chernobilsky. Studies have found that people with erectile dysfunction are more than twice as likely to have sleep apnea than people without ED, according to the National Sleep Foundation. Poor sleep and irregular sleep patterns are to blame.
Your kid is acting up
Sleep apnea strikes children too. And behavioral issues such as misbehaving at school, a poor attention span, and a drop in grades might be telling signs of sleep apnea, says Dr. Chernobilsky. “Sleep apnea in kids can present as hyper, irritable, or falling sleep in class, and some parents get a misdiagnosis of attention deficit disorder [ADD],” he says.
A 2015 review of 16 studies related to sleep apnea in children, published in Pediatrics, found that those with sleep apnea performed worse on language arts, math, and science tests compared to those without.

Your child wets the bed
If your child was potty trained but starts to wet the bed again, consider talking to their doctor about possible sleep apnea, says Dr. Chernobilsky. “When their breathing is disturbed oxygen levels drop, which makes them lose bladder function,” he says.
