Relationship Between High Blood Pressure and Sleep-Disordered Breathing
Delving into the Relationship Between High Blood Pressure and Sleep-Disordered Breathing: A Whole-Patient Approach
High blood pressure, or hypertension, is a prevalent cardiovascular condition that can be significantly impacted by sleep-disordered breathing, such as obstructive sleep apnea (OSA) and upper airway resistance syndrome (UARS). These sleep conditions are characterized by repeated interruptions in breathing, leading to oxygen desaturation and fragmented sleep. The physiological stress caused by these events can contribute to the development or worsening of hypertension, highlighting the importance of a whole-patient approach to management that addresses both sleep and cardiovascular health.
The Connection Between High Blood Pressure and Sleep-Disordered Breathing
Sleep-disordered breathing exerts several influences on the cardiovascular system, including increased sympathetic nervous system activity, inflammation, and oxidative stress, all of which can contribute to elevated blood pressure levels. The repetitive cycles of apnea and hypopnea lead to transient spikes in blood pressure throughout the night, increasing the overall risk of developing sustained hypertension.
- Nocturnal Hypertension: Characterized by elevated blood pressure levels specifically during sleep, often a result of sleep-disordered breathing.
- Daytime Blood Pressure Regulation: The effects of poor sleep quality and oxygen desaturation can extend into daytime hours, affecting overall blood pressure regulation.
Distinguishing the Impact of Sleep-Disordered Breathing
Unlike primary hypertension, which can develop due to a variety of factors including genetics, diet, and lifestyle, hypertension related to sleep-disordered breathing has a distinct pathophysiology linked to the disruptions in normal breathing patterns. Recognizing the signs of sleep-disordered breathing in patients with hypertension is crucial for effective treatment and can lead to significant improvements in blood pressure control.
Prevalence and Clinical Importance
The prevalence of hypertension among individuals with sleep-disordered breathing is notably high, underscoring the clinical importance of screening for sleep disorders in patients with elevated blood pressure. Effective management of sleep-disordered breathing can help improve sleep quality and contribute to better blood pressure regulation and reduced cardiovascular risk.
Underlying Causes
Factors that intertwine sleep-disordered breathing with hypertension include:
- Intermittent Hypoxia: Leads to increased sympathetic activity and vasoconstriction.
- Fragmented Sleep: Disrupts the normal sleep architecture, impacting the regulation of hormones involved in blood pressure control.
- Inflammatory and Oxidative Stress Responses: Triggered by recurrent apneas, contributing to endothelial dysfunction and arterial stiffness.
Identifying Symptoms
Symptoms that may indicate a link between hypertension and sleep-disordered breathing include:
- Resistant Hypertension: High blood pressure that is difficult to control with medications.
- Loud Snoring and Observed Apneas: Common indicators of sleep-disordered breathing.
- Daytime Sleepiness: Due to disrupted sleep patterns.

Many people from infancy and into old age suffer from undiagnosed disorders that could be fixed. You don’t have to suffer, we’re here to help, we see you, we’ve got you.
Diagnostic and Treatment Pathways
A comprehensive approach to addressing hypertension in the context of sleep-disordered breathing involves:
- Sleep Studies: Polysomnography to diagnose sleep-disordered breathing conditions.
- Positive Airway Pressure Therapy: Such as CPAP, to treat OSA and potentially lower blood pressure.
- Lifestyle Modifications: Including weight management, dietary changes, and exercise to support overall cardiovascular health.
BreatheWorks' Integrated Care Approach
At BreatheWorks, we adopt a whole-patient approach to managing the intricate relationship between hypertension and sleep-disordered breathing. Our care strategy includes:
- Whole-Patient Assessment: Conducted by a Speech-Language Pathologist, we take a detailed case history to get a clear picture of your body’s story and assess the function of the speech and breathing mechanisms. We will observe how the muscles perform tasks like speaking, chewing, swallowing, clearing your teeth, and breathing and identify the contributing factors that may relate to your symptoms.
- Tailored Treatment Plans: Addressing both cardiovascular and sleep health to optimize outcomes.
- Multidisciplinary Collaboration: Engaging cardiologists, sleep specialists, and dietitians to provide a cohesive management plan.
- Patient Education and Support: Offering resources and guidance on lifestyle changes, medication adherence, and the use of therapeutic devices for sleep-disordered breathing.
Conclusion
The relationship between high blood pressure and sleep-disordered breathing underscores the need for an integrated, whole-patient approach to care. By addressing the underlying sleep conditions, patients can achieve not only improved sleep quality but also better blood pressure control, enhancing overall health and reducing the risk of cardiovascular complications. BreatheWorks is dedicated to supporting patients through comprehensive care that targets both hypertension and sleep-disordered breathing, promoting long-term wellness and improved quality of life.

Orofacial Myofunctional Disorders (OMD)
Orofacial Myofunctional Disorders (OMD) refer to a group of conditions characterized by abnormal patterns of muscle function and incorrect habits involving the face, mouth, and throat. These disorders can affect various aspects of oral function, including speech, swallowing, breathing, and facial development. Examples of OMD include tongue thrust (where the tongue pushes against or between the teeth during swallowing or at rest), open mouth posture (habitual mouth breathing with the mouth consistently open), and incorrect tongue resting position. OMD can contribute to dental malocclusions, speech articulation difficulties, temporomandibular joint (TMJ) dysfunction, and other orofacial issues.Orofacial Myofunctional Therapy (OMT or MYO)
Orofacial myofunctional therapy (OMT) is a specialized form of therapy designed to address and correct Orofacial Myofunctional Disorders (OMD). It focuses on retraining the muscles of the face, mouth, and throat to achieve proper resting posture, swallowing patterns, and speech articulation. OMT involves a variety of exercises, techniques, and behavioral modifications tailored to the individual’s specific needs and goals. The goals of OMT include improving orofacial muscle strength and coordination, correcting abnormal swallowing patterns, promoting nasal breathing, and enhancing overall oral function and health. OMT is typically provided by speech-language pathologists or therapists trained in orofacial myofunctional therapy techniques.Benefits of Orofacial Myofunctional Therapy (OMT)
Orofacial myofunctional therapy (OMT) can be highly beneficial for individuals with Orofacial Myofunctional Disorders (OMD). By addressing underlying muscle dysfunction and promoting proper oral habits, OMT can help improve speech clarity, correct swallowing patterns, alleviate breathing difficulties, and optimize facial development. However, the effectiveness of OMT depends on various factors, including the severity of the OMD, the individual’s commitment to therapy, and consistency in practicing exercises and techniques. OMT is often recommended as part of a comprehensive treatment plan in collaboration with other healthcare professionals, such as dentists, orthodontists, and ENT specialists, especially when addressing complex orofacial issues.We hold space in our clinicians’ schedules for new patients because we know that early intervention is the best approach.
