As a pediatric pelvic floor physical therapist, I work with families every day who are managing bed-wetting challenges with their children. Bed-wetting, or nocturnal enuresis, is a common concern for parents, and it can be stressful for children, affecting their self-esteem and social experiences. While there are many potential contributors to bed-wetting, one lesser-known factor that fascinates me and often surprises parents is mouth breathing. In this post, I’ll explain how mouth breathing can impact bed-wetting and discuss steps you can take to address this issue.
Understanding Mouth Breathing in Children
What Is Mouth Breathing?
Mouth breathing is simply breathing through the mouth rather than the nose. While it can happen occasionally—like during a cold or congestion—for some children, it becomes a regular habit. Common causes of mouth breathing include nasal congestion, enlarged tonsils or adenoids, allergies, or structural nasal issues. Because mouth breathing is so common among children with these conditions, it’s important to recognize when it may be playing a role in bed-wetting.
Why Does Mouth Breathing Matter?
Breathing through the mouth, especially while sleeping, can impact a child’s overall health, including their sleep quality, energy levels, and even dental development. Mouth breathing often leads to fragmented or less restful sleep, which has a cascading effect on other bodily functions—including bladder control.
Understanding Bed-Wetting (Nocturnal Enuresis)
What Is Bed-Wetting?
Nocturnal enuresis, or bed-wetting, is involuntary urination that happens during sleep. It can be classified as either primary (when a child has never had dry nights for an extended period) or secondary (when a child starts wetting the bed again after a period of staying dry). Bed-wetting is quite common, and it’s often a natural part of development for younger children. However, if bed-wetting persists beyond the typical age or starts impacting a child’s well-being, it’s worth exploring possible underlying causes.
Common Contributors to Bed-Wetting
Bed-wetting can stem from several factors, including genetics, delayed bladder development, deep sleep cycles, stress, and lifestyle habits. However, one connection that’s increasingly coming to light is the impact of mouth breathing on bed-wetting patterns.
How Mouth Breathing Can Contribute to Bed-Wetting
As we explore the mouth breathing-bed-wetting connection, there are a few key factors to consider.
Hormone Production
Sleep quality affects our bodies in many ways, including hormone production. The antidiuretic hormone (ADH) is released during sleep to help reduce urine production, allowing us to sleep through the night without needing the bathroom. When sleep is disrupted, ADH levels can fluctuate, leading to higher urine production at night and an increased likelihood of bed-wetting.
2. Sleep Apnea
Mouth breathers often have a tendency to snore while sleeping or to temporarily stop breathing while sleeping (apnea). In this scenario, the blood oxygen level drops and the carbon dioxide level rises, triggering the release of a surge of adrenaline to wake you up and take a big breath. This rush of adrenaline certainly serves to disrupt sleep, but it has also been suggested that the rapid inhalation causes a dramatic enough shift in pressure on the heart that the body thinks there is fluid compressing the heart. To compensate for this, the body shifts the kidneys into overdrive, facilitating even greater urine production. The reduced oxygen levels put additional stress on the body. For children, this can increase physiological stress and even irritate the bladder.
Treatment Approaches and Interventions
If your child is struggling with both mouth breathing and bed-wetting, here are some strategies and treatments that may help.
Treating Mouth Breathing
Address Nasal Blockages: Visit an ENT specialist to determine if your child has any physical obstructions like enlarged tonsils or adenoids that can be addressed.
Consider an Orthodontic Evaluation: Sometimes, jaw alignment or dental issues can contribute to mouth breathing. A pediatric orthodontist can assess if structural concerns are contributing.
Breathing Exercises: Working with a pediatric therapist who specializes in breathing can help your child develop healthier breathing habits. Speech therapists can help myofunctional exercises before or after nasal or dental work.
Behavioral and Lifestyle Changes
Practice Good Sleep Hygiene: Regular sleep routines, a calm bedtime environment, and limiting fluids before bed can support better sleep and bladder control.
Monitor diet and fluid intake: Avoid irritating foods and drinks and spreading out fluid intake throughout the day helps to maintain a happy bladder.
Pelvic Floor Physical Therapy
Pediatric Pelvic Floor Therapy: A pediatric pelvic floor physical therapist can work with children to improve bladder function and educate families on managing bed-wetting. We address a variety of skills and activities including reflexes, breathing patterns, core strength and bowel function to determine their impact on bladder function. We use a combination of exercises, education, and sometimes biofeedback to help children gain awareness of their pelvic floor muscles and control over their bladder to overcome bed-wetting. Children can also learn awareness of their bladder signals which helps them recognize and respond to the urge to go during the day for better control at night.
Conclusion
Bed-wetting is challenging, but understanding the role of mouth breathing offers an opportunity for targeted intervention that can improve sleep, breathing, and bladder control all at once. If you suspect that mouth breathing is contributing to your child’s bed-wetting, reaching out to a specialist can be a powerful first step toward improving their overall well-being.
Addressing mouth breathing and bed-wetting early on can make a significant difference in a child’s life, both physically and emotionally. If you have questions or would like guidance, consider reaching out to a pediatric specialist, such as an ENT, orthodontist, or pediatric pelvic floor physical therapist, to discuss options for treatment. Together, we can help your child develop the skills they need for restful sleep and dry nights.
