Snoring can keep you awake, ruin your sleep cycle and your daily rhythm, even harm your relationships. But more than being just an annoyance, snoring may bring about life-threatening consequences.
If you’ve ever awakened yourself with a sudden snore — or if your partner nudges you awake to get you to turn over — it’s possible you could be affected by sleep apnea, which is associated with high blood pressure, arrhythmia, stroke and heart failure.
Isn’t sleep apnea just a fancy name for snoring?
Not at all. Snoring is that annoying sound that occurs when air passes relaxed tissues in your throat as you sleep. Sleep apnea is a disorder in which a person’s breathing repeatedly starts and stops during sleep.
Not everyone who snores has sleep apnea, but many who have sleep apnea do snore regularly — and loudly. One in five adults suffers from at least mild sleep apnea; it afflicts more men than women.
The most common type is obstructive sleep apnea (OSA), in which weight on the upper chest and neck contributes to blocking the flow of air. A less-common type, central sleep apnea (CSA), occurs when the brain fails to send regular signals to the diaphragm to contract and expand. CSA has been associated with brain stem stroke.
Why is this a big deal?
For people with OSA, it becomes difficult to keep the upper airway open during sleep because weight overpowers the muscles that hold it open. Each time the airway closes during sleep, there is a pause in breathing; it can happen five to 30 times an hour or more, causing the sleeper to wake up suddenly, gasping for air.
When the air flow stops, the body releases stress hormones, which over time can lead to heart disease — the leading cause of death in the United States — stroke and high blood pressure. It also can increase the risk of type 2 diabetes, liver problems and .
It’s also associated with obesity, and experts say it can be part of a vicious cycle in which the sleep deprivation it causes can lead to even more obesity, which in turn makes the condition worse.
Who’s at risk?
People who are overweight are especially at risk for OSA because fat deposits around the upper airway can cause the airway’s muscles to lose tone over time, leading to obstructed breathing. Similarly, people with thicker necks, narrow throats or enlarged tonsils or adenoids may also be at risk.
Men are more likely to have sleep apnea than women, and it occurs significantly more often in older adults. There also may be an increased risk for people with a family history of sleep apnea, smokers or drinkers.
What are the signs?
Aside from loud snoring and sudden stopped breathing or gasping for air during sleep (observed by someone else, obviously), symptoms may seem similar to those of any sleep disorder:
- Waking up with a dry mouth
- Morning headaches
- Difficulty sleeping or excessive sleepiness
- Irritability or trouble paying attention while awake
How can I know for sure?
Your doctor can evaluate your symptoms, but you may need a sleep specialist to conduct testing, such as overnight monitoring of your breathing, to diagnose your condition and determine its severity.
Using a test called polysomnography, your doctor can monitor your heart, lung and brain activity and other movements while you sleep. This study helps rule out other sleep disorders such as restless legs syndrome or narcolepsy.
¿Cómo se trata?
For moderate to severe cases, your doctor may recommend devices or treatments — or even surgery to help open the airway.
Common therapies include continuous positive airway pressure (CPAP), in which a machine delivers constant air pressure through a mask into the nose or mouth, or a mouthpiece that is designed to keep a person’s throat open.
If you have a mild case and you’re struggling to get a good night’s sleep, your doctor may suggest lifestyle changes, such as:
- Realice actividad física de forma habitual, pero no justo antes de acostarse, ya que esto hace que la adrenalina aumente y se mantenga despierto.
- Limite el consumo de alcohol a una bebida al día si es mujer y a dos bebidas si es hombre. El exceso de alcohol interfiere en el sueño.
- Evite la cafeína antes de dormir.
- Desarrolle una rutina para antes de acostarse, como darse un baño caliente, atenuar las luces o beber un poco de té de hierbas.
