Sleep Apnea and Psoriasis: What's the Connection?

Quick answer: Sleep apnea and psoriasis are two separate health conditions that researchers have observed occurring together more often than chance would suggest. The exact connection is not fully understood, and having one condition does not mean you will develop the other. If you have symptoms of either condition, talk with your clinician about appropriate evaluation and next steps.

What is sleep apnea?

Sleep apnea is a sleep-related breathing disorder in which breathing repeatedly stops and starts during sleep. The most common form is obstructive sleep apnea, where the throat muscles relax and block the airway. Central sleep apnea is less common and involves the brain not sending proper signals to the muscles that control breathing. Typical signs include loud snoring, gasping for air during sleep, waking with a dry mouth, morning headaches, and excessive daytime sleepiness. Many people with sleep apnea are unaware of their breathing pauses until a bed partner notices them.

What is psoriasis?

Psoriasis is a chronic skin condition that causes skin cells to build up rapidly, forming thick, silvery scales and itchy, dry, red patches. It is not contagious. Plaque psoriasis is the most common type, often appearing on the elbows, knees, scalp, and lower back. Symptoms can flare and subside over time. Triggers vary by person and may include stress, skin injury, certain medications, infections, and weather changes. Psoriasis can also be associated with psoriatic arthritis, which affects the joints.

How might sleep apnea and psoriasis be connected?

Some studies have observed that people with psoriasis may have a higher likelihood of also having sleep apnea compared with people without psoriasis. Researchers have proposed several possible explanations, including shared inflammation pathways and common risk factors such as obesity. However, these observations do not prove that one condition causes the other. The relationship between sleep apnea and psoriasis remains an active area of research, and more evidence is needed before firm conclusions can be drawn.

What the research shows so far

Observational studies have reported associations between sleep apnea and psoriasis, but results vary. Some research suggests that the severity of psoriasis may correlate with the presence or severity of sleep apnea, while other studies find weaker links. Because most existing data are observational, they cannot establish cause and effect. Confounding factors such as body mass index, smoking, alcohol use, and other health conditions may influence both conditions. Large, long-term studies are still needed to clarify whether treating one condition affects the other.

Shared risk factors to consider

Several factors may increase the likelihood of developing both sleep apnea and psoriasis. Obesity is a well-established risk factor for obstructive sleep apnea and is also associated with more severe psoriasis. Smoking and heavy alcohol use can worsen sleep apnea symptoms and may trigger psoriasis flares. Other conditions, including high blood pressure and type 2 diabetes, appear more frequently in people with either condition. Age and family history also play roles for both disorders.

Factor	Sleep Apnea	Psoriasis
Primary nature	Breathing disorder during sleep	Chronic immune-mediated skin condition
Common age range	Often diagnosed in adults 30-60	Often begins between ages 15-35
Key risk factor	Excess weight, neck circumference	Family history, immune system factors
Typical clue	Loud snoring, daytime sleepiness	Scaly, red skin patches

When to talk to a clinician

You should consider speaking with your clinician if you experience loud snoring, witnessed breathing pauses during sleep, or persistent daytime fatigue. Skin changes such as persistent red, scaly patches that do not improve with basic care also warrant evaluation. If you have both sleep symptoms and skin symptoms, mention them together so your clinician can assess whether separate referrals are appropriate. A sleep specialist may recommend a sleep study, while a dermatologist can evaluate skin concerns.

What to expect next: evaluation steps

1. Schedule an appointment with your primary care clinician to discuss your symptoms.
2. Describe any snoring, breathing pauses, daytime sleepiness, or skin changes in detail.
3. Ask whether a referral to a sleep specialist or dermatologist is appropriate.
4. If a sleep study is recommended, learn what happens during a sleep study so you can prepare.
5. Follow up on test results and discuss treatment options with your clinician.

Frequently asked questions

Can sleep apnea cause psoriasis?

Research has not established that sleep apnea causes psoriasis. Some studies show an association between the two conditions, but causation has not been proven.

Can psoriasis cause sleep apnea?

There is no proven evidence that psoriasis directly causes sleep apnea. Shared risk factors such as obesity may explain why they sometimes occur together.

Should I treat my psoriasis to help my sleep apnea?

You should not change any treatment expecting it to affect the other condition without speaking with your clinician. Each condition is typically managed separately based on its own guidelines.

How do I find a sleep clinic?

What happens during a sleep study?

A sleep study typically monitors breathing, oxygen levels, heart rate, and brain activity while you sleep. Learn more in our overview of what happens during a sleep study.
