High Altitude and Snoring: The Connection

High altitude can worsen snoring and sleep apnea due to changes in breathing patterns and reduced oxygen levels, leading to disrupted sleep. The overall apnea-hypopnea index (AHI), which measures sleep apnea severity, is higher for individuals with obstructive sleep apnea (OSA) at altitude, indicating an increase in sleep apnea severity.

Grasping the link between high altitude and snoring is beneficial for managing sleep disruptions in elevated regions.

Breathing Changes at High Altitude

At high altitudes, the air pressure and oxygen levels are lower, making respiration more arduous as the body must exert more effort to acquire sufficient oxygen. This can lead to altitude-induced sleep disturbances, such as:

  • high altitude periodic breathing, where breathing patterns become unstable and episodes of deep and rapid breathing occur

  • difficulty in breathing

  • coughing

  • confusion

  • an inability to walk in a straight line

In some cases, more severe symptoms may manifest.

Decreased oxygen in the blood at high altitude commonly results in breathing instability, manifested as periodic rather than normal breathing. This irregular breathing pattern can be especially challenging for individuals with preexisting respiratory conditions or those who are not accustomed to high altitudes. Healthy mountaineers ascending rapidly may also experience breathing difficulties and sleep disturbances.

Our bodies need to adjust to the changing environment as we climb to higher altitudes. Altitude acclimatization is a vital process that helps prevent altitude sickness and other altitude-related illnesses.

However, it’s important to note that acclimatization takes time and varies from person to person. So, while some may experience minimal sleep disturbances, others might suffer from more severe symptoms like insomnia or acute mountain sickness.

Effects on Sleep Quality

High altitude can adversely impact sleep quality, leading to escalated snoring and sleep apnea symptoms due to the body’s struggle to maintain regular breathing. Exposure to high altitude can lead to:

  • Sleep disturbances

  • Reduced sleep efficiency

  • Sleep fragmentation

  • Insomnia

The reduced oxygen levels at high altitude can significantly influence sleep quality and may cause some individuals to develop central sleep apnea.

Decreased oxygen levels at high altitude prompt the body to strive for maintaining regular breathing. This can result in augmented snoring and sleep apnea symptoms, which can have a detrimental effect on sleep quality, especially for patients with obstructive sleep apnea. Furthermore, at high altitudes, complications related to central sleep apnea can also occur.

Various strategies can be adopted to manage sleep disordered breathing like snoring and sleep apnea at high altitude.

Central sleep apnea, a less common form of sleep apnea, can be triggered or worsened by high altitude, leading to interrupted breathing during sleep. Unlike obstructive sleep apnea, where the airway is physically blocked, central sleep apnea occurs when the brain fails to send the proper signals to the muscles that control breathing.

High altitude-induced central apnea is a type of central sleep apnea that can occur due to respiratory instability induced by altitude, resulting in periodic breathing and central apneas during sleep.

Individuals with central sleep apnea may experience snoring, but it may not be as pronounced as with obstructive sleep apnea. Treatment-emergent central sleep apnea, a combination of obstructive and central sleep apneas, can develop in some individuals with obstructive sleep apnea while utilizing continuous positive airway pressure (CPAP) therapy. Complications central sleep apnea may present can further impact the effectiveness of the treatment.

In some cases, complex sleep apnea can be alleviated with sustained use of the CPAP device.

Cheyne-Stokes Breathing

Cheyne-Stokes breathing is a type of central sleep apnea that is typically associated with heart failure or stroke, and its occurrence can be intensified at high altitudes. This abnormal pattern of breathing is characterized by progressively deeper and sometimes faster breaths, followed by periods of shallow or no breathing. Cheyne-Stokes breathing is a condition of considerable severity that can be linked to a range of medical conditions, including nighttime breathing symptoms.

Individuals with Cheyne-Stokes breathing may experience more severe symptoms at high altitudes as the reduced oxygen levels and changes in air pressure can exacerbate the condition. Moreover, the impact of high altitude on Cheyne-Stokes breathing can be particularly challenging for individuals with preexisting heart failure or stroke.

It’s essential for individuals with Cheyne-Stokes breathing to consult a healthcare professional before traveling to high altitudes.
