Overview of Sleep Devices
Sleep apnea and other sleep disorders can disrupt your quality of life, affecting your energy levels, mood, and overall health. Fortunately, various devices are designed to help manage these conditions. Below, we provide an overview of the four main types of sleep devices:
- CPAP (Continuous Positive Airway Pressure) Machines
- BiPAP (Bilevel Positive Airway Pressure) Machines
- Oral Appliances
- Wearable Sleep Trackers
Each of these devices serves a unique purpose and has varying impacts on safety and comfort. Let’s take a closer look at each device type.
1. CPAP and BiPAP Machines
CPAP machines are the most commonly used devices for treating moderate to severe obstructive sleep apnea (OSA). They work by delivering continuous air pressure to keep your airways open during sleep. On the other hand, BiPAP machines provide a variable pressure for inhalation and exhalation, making them ideal for those who struggle with exhaling against constant pressure.
Common side effects of CPAP and BiPAP machines include:
- Nasal congestion
- Dry mouth and nose
- Facial discomfort or skin irritation from the mask
- Dry eyes
- Claustrophobia or discomfort when exhaling
Long-term risks are rare but can include:
- Dental changes, especially in children
- Middle ear discomfort
- In some older machines, breakdown of foam can release toxic gases
Serious complications are uncommon but may arise from improper use or lack of maintenance, such as increased infection risk or improper pressure settings. Despite these issues, CPAP and BiPAP machines are considered safe for most users, with most side effects being manageable with mask adjustments or adding a humidifier to the setup.

2. Oral Appliances
Oral appliances (also known as mandibular advancement devices (MADs) or tongue-retaining devices (TRDs)) are typically used for mild to moderate obstructive sleep apnea. These devices work by repositioning the jaw or tongue to keep the airways open during sleep. They are a popular alternative for those who find CPAP machines uncomfortable or impractical.
Common side effects of oral appliances include:
- Dry mouth or excess saliva
- Tooth discomfort
- Jaw pain or muscle soreness
- Teeth grinding
- Changes in bite alignment
Long-term risks are rare but can include:
- Dental or jaw alignment changes
- Potential for jaw or tooth damage over extended use
While serious complications are uncommon, oral appliances require regular dental follow-up to ensure they are not causing damage to your teeth or jaw. Most side effects are mild and improve with continued use or adjustments by your dentist.

3. Positional Therapy Devices
Positional therapy devices are designed to help individuals with positional obstructive sleep apnea (OSA), which occurs when the airway becomes blocked during sleep, typically when lying on the back. These devices may include wearable sensors that help prevent the user from sleeping on their back.
Common side effects of positional therapy devices include:
- Mild back or chest pain
- Occasional discomfort from wearing the device
- Sleep disturbances due to the device’s positioning
Long-term risks are minimal, and no significant complications have been reported in studies. Overall, positional therapy is considered safe, especially for people with positional OSA or those who cannot tolerate CPAP therapy.

4. Wearable Sleep Trackers
Wearable sleep trackers, such as the Oura Ring, Fitbit, and Apple Watch, are growing in popularity for tracking sleep patterns and improving overall sleep quality. While these devices are not intended for diagnosing sleep apnea, they offer valuable insights into your sleep habits, stress levels, and even heart rate variability.
Common side effects of wearable trackers include:
- Skin irritation or allergic reactions from prolonged wear
- Discomfort from wearing the device on the wrist or finger
Despite the minor discomforts, these devices are generally considered very safe for the majority of users. They emit low-level, non-ionizing radiation, which is far below international safety limits and is considered harmless.
Serious complications are virtually non-existent for wearable sleep trackers, though there may be concerns regarding data privacy and potential misuse of personal sleep data by third parties.

Safety Comparison Table
Below is a quick reference table that compares the safety profiles, side effects, and long-term risks of the sleep devices we’ve discussed. This will help you easily visualize the key takeaways for each device:
| Device Type | Common Side Effects | Long-Term Risks | Serious Complications | Overall Safety |
|---|---|---|---|---|
| CPAP/BiPAP | Nasal dryness, skin irritation, discomfort when exhaling, dry eyes, bloating | Dental changes (rare), ear discomfort, foam breakdown (rare) | Infections (rare), improper use risks | Safe for most, with manageable side effects |
| Oral Appliances | Dry mouth, jaw pain, dental discomfort, bite changes | Dental and jaw alignment changes (rare) | Rare | Safe for most, requires regular dental follow-up |
| Positional Therapy Devices | Mild back or chest pain, sleep disturbances | Minimal long-term risks | Very rare | Safe for positional OSA |
| Wearable Sleep Trackers | Skin irritation, mild discomfort | No long-term risks known | None reported | Very safe, though not a substitute for medical treatment |
As seen in the table, each device has its unique strengths and weaknesses in terms of safety. While CPAP and BiPAP machines are very effective for sleep apnea treatment, their side effects and risks must be carefully managed. Oral appliances are a safer, more comfortable alternative but should be monitored by a dentist. Positional therapy devices offer a non-invasive option with minimal risks, while wearable trackers provide insightful data but should not replace medical-grade treatments for sleep apnea.
Key Takeaways and Conclusion
In summary, here are the key takeaways about the safety of each device:
- CPAP and BiPAP: These are the most effective devices for moderate to severe OSA, but they come with side effects like nasal dryness, facial discomfort, and rare risks such as dental changes. Proper maintenance and mask adjustments can alleviate most issues.
- Oral Appliances: A great alternative for mild to moderate OSA, especially for those who struggle with CPAP. They carry some risk of dental discomfort and alignment changes, but these can be minimized with regular dental visits.
- Positional Therapy Devices: Perfect for positional OSA, these devices have minimal side effects and no significant long-term risks. They are an excellent option for those who can’t tolerate CPAP therapy.
- Wearable Sleep Trackers: While not suitable for diagnosing or treating sleep apnea, wearable trackers like Oura Ring and Fitbit are a safe way to monitor sleep patterns and improve sleep quality over time. Just be mindful of data privacy concerns.
Choosing the right sleep device is a personal decision that depends on your specific condition, comfort preferences, and safety considerations. While CPAP and BiPAP machines are the gold standard for severe OSA, there are effective alternatives like oral appliances and positional therapy devices for those with milder conditions or discomfort with CPAP. Wearable trackers provide an excellent non-invasive way to monitor sleep and overall wellness, though they should not be used as a substitute for professional medical treatments when needed.
If you are struggling with sleep issues, consult your healthcare provider to determine the best course of action and which device is right for you.
