Snoring: Causes, symptoms and solutions

Snoring is a common nighttime occurrence that happens while you sleep.1 Some people snore gently, like a purring cat. Others may sound more like a rattling chainsaw when they snore, disrupting sleep for both the person snoring and their bed partner. So, why do you snore? In some cases, snoring can be completely harmless. In other instances, it may be a sign of a more serious medical condition like sleep apnea2, making it even more important to understand the cause behind your snoring.

 

What snoring could signal about your health

Snoring isn’t just an annoying sound, it may be a sign of underlying health issues. In some cases, snoring may indicate sleep apnea or other conditions that affect your breathing and overall well-being. Here are some related signs to watch for3:

  • Loud snoring that disrupts sleep

  • Gasping for air during sleep

  • Waking up with a dry mouth or sore throat

  • Excessive daytime sleepiness

  • Difficulty concentrating

What causes snoring?

Snoring can be caused by a variety of lifestyle and/or natural, anatomical factors. Snoring causes include1:

  • Airway obstruction: Enlarged tonsils or a large uvula (the small, punching bag-shaped tissue that dangles from the back of the soft palette in your mouth) can cause an obstruction that causes you to snore.

  • Nasal problems: Persistent nasal congestion or deviated nasal septum (a crooked partition between the nostrils) can make snoring more likely.

  • Alcohol use: Drinking alcohol – especially before bed – can relax your throat muscles too much and slow down your body’s natural wake-up signals. Alcohol consumption can relax the muscles in the throat, making the airway more prone to partial obstruction

  • Sleeping position: Your sleeping position can also play a role in whether you snore or not. Sleeping on your back can cause you to snore more than other positions.

Why do I snore? Understanding personal triggers for snoring

From your unique body type to your lifestyle choices, every person is different. While there are more general reasons behind snoring, the bigger question to ask yourself is “Why do I snore?” Taking stock of your body type, allergies, habits and overall health can help you pinpoint personal triggers behind your snoring.1 

You can use a journal or app to log your behaviors to help you figure out possible triggers for your snoring. This can be helpful to share with your doctor to better understand the problem and how to solve it together.

 

Why does my bed partner snore?

If your bed partner snores loudly, it can disturb your sleep, and potentially put a strain on your relationship.4 Snoring can be caused by various factors such as sleeping position, allergies, sleep patterns, health issues and lifestyle choices such as alcohol use and smoking.1 Dealing with a snoring bed partner can be frustrating, but working together can help you both find a way to improve your sleep, energy, health and quality of life.

 

Snoring and sleep apnea symptoms: Are they linked?

Just because you snore doesn’t necessarily mean that you have sleep apnea. However, snoring regularly can be a potential sign of obstructive sleep apnea. Other tell-tale signs of sleep apnea include pauses in breathing and gasping for air while sleeping. While snoring can be annoying for both you and your bed partner, it should prompt you to talk to your doctor about sleep apnea.

 

How to stop snoring: Effective solutions

Some common ways to stop snoring involve lifestyle changes.5 Adjusting your sleeping position is a small-but-simple change that can reduce your snoring. For instance, if you normally sleep on your back, sleeping on your side may help you stop snoring.

Other lifestyle changes that can help you stop snoring include avoiding alcohol and smoking. If you often find yourself reaching for a glass of wine or beer to unwind before bedtime, saying “no” to that nightly drink may help reduce your snoring. Getting more exercise and losing weight can also have a positive impact on your snoring. Weight loss can reduce the amount of fatty tissue around your neck and airways. As a bonus, exercise can aid weight loss and help reduce bodily fluids that put pressure on your upper airway when you sleep.6

 

When should you consult a doctor for snoring?

If you’ve tried any combination or all of the tips we’ve mentioned and still see no improvement in your snoring–or if it’s getting worse–visit your doctor to get checked for sleep apnea. If your snoring is loud, frequent, or you find yourself waking up short of breath, your doctor can help you determine whether your snoring is a symptom of a more serious condition like sleep apnea. No matter the cause of your snoring, getting to the root of the problem can help you — and your sleep partner — have a more restful night’s sleep and wake up with more energy to face your day.

Sleep Revitalizes your Mind, Body, & Heart

The body goes under many transformations, while it is in the state of rest during sleep. There are many essential functions that take place in the body such as tissue repair, memory and energy restoration, release of essential hormones, muscle relaxation, and others. While you are asleep, the brain releases indispensable hormones that promote tissue growth. This process helps your body rejuvenate from the daily hustle bustle. Moreover, tissue growth aids in the recovery from wounds or cuts. Sunita Kumar, Co-Director, Centre for Sleep Disorders, Loyola University Medical Centre, aptly remarks that during sleep the body produces more white blood cells, to fight countless bacteria and viruses1. The heart rate also registers a dip during sleep, which according to Ms. Kumar, strengthens the heart as it is at rest with lowered activity. Moreover, a good night’s sleep also reduces the chances of getting afflicted with heart diseases.

Good Sleep = Sharp Memory

Sleep is a time, when becomes sharp and strong. Sleep quantity and quality play a fundamental role in determining what one remembers and what one doesnt. Therefore, development of long-term memory (LTM) from short-term memory (STM) happens during sleep.  Scientific researches state that the brain follows a different mechanism for storing memories through the hippocampus and neo-cortex areas. Hippocampus helps you to remember your life experiences (childhood memories), while the neo-cortex is responsible for remembering the concepts you learn (name of a color). Communications and sync between the two, helps in learning new data and updating old ones.

Sleep Steers Hormonal Hunger

Sleep not only affects your energy levels and mental functions, but also regulates your body weight. Improper sleep is related to the increasing cases of obesity, worldwide2. Many hormones which regulate the feeling of hunger (ghrelin) and signal the feeling of being full (leptin), are all influenced by the quality of your sleep.  Leptin: This is also known as satiety hormone, which is produced by the fat cells of the body. It prevents overeating by sending signals to the brain that the body does not require more food, as there is enough to fuel the body.  Ghrelin: This hunger hormone is produced in the gastrointestinal tract, which signifies the body that there is need for food. This hormone rises in the body, when you feel hungry and decreases when you have consumed some food.  Studies show that people who have disrupted patterns of sleep - have larger appetite, because of higher ghrelin secretion and lowered secretion of leptin. This imbalance in the secretion of these hormones is a result of improper sleep patterns3.
