A Sleep Study, also known as Polysomnography, is a non-invasive diagnostic test that records your body’s activity while you sleep. It helps detect sleep disorders such as sleep apnea, snoring, insomnia, restless legs syndrome, and more.
During the study, a specialized device monitors various parameters like:
Breathing patterns
Heart rate
Oxygen levels
Brain activity
Eye and muscle movements
At-home sleep studies use portable diagnostic equipment like Alice PDx or ResMed ApneaLink Air, making it convenient and comfortable to undergo the test in your own bedroom.
Data sheet
Please take the advice of the authorized medical practitioner before use.
1. What is a sleep study and how is it done at home?
A sleep study is a test used to diagnose sleep apnea by monitoring your breathing, oxygen levels, and sleep patterns overnight. With a home sleep study, you can do this in the comfort of your own bed using compact, FDA-approved devices like the ResMed ApneaLink Air or Alice PDx—no need to visit a sleep lab.
2. What equipment will I need to wear?
You’ll be guided to wear a nasal cannula to track airflow, belts around your chest and abdomen to monitor breathing effort, and a finger sensor to check oxygen levels and heart rate. Advanced kits may also include sensors to monitor brain activity and sleep stages.
3. What does the test detect?
The sleep study identifies apneas (complete pauses in breathing), hypopneas (shallow breaths), drops in oxygen levels, and interruptions in your sleep cycles or body position—giving your doctor a full picture of your sleep health.
4. What are the symptoms of sleep apnea I should look out for?
Common signs include loud snoring, choking or gasping during sleep, dry mouth, morning headaches, and daytime fatigue. Often, these are first noticed by a bed partner.
5. Why do people with sleep apnea feel tired even after sleeping?
Because sleep apnea causes repeated brief awakenings due to breathing interruptions, your body doesn’t reach deep, restful sleep—leaving you exhausted the next day.
6. Is sleep apnea dangerous if left untreated?
Yes. Chronic low oxygen levels during sleep can strain your heart and raise the risk of high blood pressure, heart attack, stroke, diabetes, and accidents due to drowsiness.
7. Can sleep apnea affect mental health?
Absolutely. Poor sleep and low oxygen can lead to mood swings, anxiety, depression, and trouble with focus and memory.
8. Does sleep apnea contribute to weight gain?
Yes. It disrupts hormones that control hunger and fullness, making you more likely to overeat. Fatigue from poor sleep also reduces physical activity.
9. Can losing weight help reduce sleep apnea?
Yes. Excess weight, especially around the neck, increases the risk of airway obstruction. Even modest weight loss can lead to significant improvement.
10. What lifestyle changes can help with sleep apnea?
Maintain a healthy weight, avoid alcohol or sedatives before bed, quit smoking, sleep on your side, and stick to a consistent sleep routine.
