Is it OK to wear a face mask overnight?

Quick Answer

For most people, it is generally safe to wear a face mask overnight as part of COVID-19 precautions or to treat certain sleep conditions. However, there are some risks to consider, especially for those with underlying health conditions like asthma or sleep apnea. Proper mask fit and material are important to reduce risks. Consulting a doctor is advisable, especially if experiencing any breathing difficulties or other concerning symptoms while wearing a mask overnight.


Wearing a face mask overnight has become more common during the COVID-19 pandemic as part of precautions to reduce disease transmission. Face masks may also be worn overnight to treat sleep disorders like sleep apnea.

However, there are some health risks associated with wearing masks for extended periods, particularly related to breathing difficulties and skin irritation. Assessing these risks and benefits on an individual level is important.

Factors like mask type, fit, and underlying medical conditions play a role in determining if overnight use is advisable. Taking proper safety precautions like cleaning masks regularly can also reduce potential risks.

Consulting with a doctor is the best way to decide if overnight mask use is recommended based on your unique health profile and sleep issues. Being aware of any concerning symptoms and adjusting mask use accordingly is also crucial.

Benefits of Wearing a Face Mask Overnight

There are a few potential benefits associated with wearing a face mask overnight:

Reducing COVID-19 transmission

Wearing a cloth or medical face mask while sleeping is one way to provide an additional layer of protection against the COVID-19 virus, especially if you sleep near others. Both cloth masks and medical masks like N95s can help prevent respiratory droplets from spreading.

Masks worn overnight may reduce the risk of presymptomatic or asymptomatic transmission of COVID-19 to household members. They provide continued protection while sleep when social distancing and other precautions may be relaxed.

Treating sleep apnea

Sleep apnea is a condition where breathing repeatedly stops and starts during sleep. Face masks like CPAP machines provided pressurized air to keep airways open, often by way of a tight fitting N95-style mask worn over the nose and mouth.

For those with diagnosed sleep apnea, overnight mask use is an important part of treating the condition and improving sleep. Masks keep airways open to facilitate continuous, uninterrupted breathing.

Providing allergen protection

Wearing certain masks overnight may provide some protection from allergens like pollen or pet dander for those with allergies or asthma. N95 masks are designed to filter out particles.

This can prevent allergen exposure during sleep that may trigger symptoms like congestion, coughing, or wheezing for those sensitive to certain allergens. Reduced reactions can also mean better sleep quality.

Potential Risks and Side Effects

While there are some benefits, there are also some potential downsides and risks to wearing a mask repeatedly or for extended periods overnight:

Breathing difficulties

Wearing a face mask could make breathing somewhat more difficult, especially for those with underlying respiratory conditions like asthma or COPD. Rebreathing exhaled carbon dioxide may also build up inside masks.

This could potentially lead to oxygen deprivation over time, especially if the mask is ill-fitting or made from non-breathable material. Those with severe lung disease may be at higher risk.

Skin irritation

Wearing masks overnight frequently may cause skin redness, irritation, acne breakouts, rashes, and other problems. The warmth and humidity inside masks are contributing factors.

Sensitive skin, allergies to mask materials, tight elastic bands, and chafing can also cause skin discomfort. Extended overnight use without washing masks regularly may increase irritation.

Interference with sleep

Some people may have difficulty falling or staying asleep while wearing a mask due to discomfort. ill-fitting masks may be distracting and cause sleep interruption for some.

CPAP masks for sleep apnea also take some adjustment for users to get comfortable wearing overnight. This may disrupt sleep initially before benefits are seen.

False sense of security

Wearing masks overnight should not replace other important precautions against COVID-19 like vaccines, social distancing, improved ventilation, and handwashing. Relying too heavily on masks may provide a false sense of security against transmission.

Who Should Avoid Wearing Masks Overnight

While overnight masking is likely low risk for most healthy individuals, certain groups are more likely to experience problems. Those who should use caution or avoid extended mask-wearing while sleeping include:

– Children under 2 years old: Risk of suffocation or choking hazards.

– Anyone with breathing problems: People with asthma, COPD, sleep apnea, or other conditions may have more difficulty tolerating masks for long periods.

– Those with anxiety disorders: Wearing masks may trigger claustrophobia or feelings of panic.

– Facial skin conditions: Eczema, acne, allergies may be aggravated by mask contact.

– Sensory processing disorders: Masks may be uncomfortable or distracting for those with sensory issues.

Consulting with a doctor is the best way to assess if overnight mask use is appropriate for those in higher risk groups.

Precautions for Safe Overnight Use

If you do choose to wear a face mask overnight, following certain precautions can help reduce risks:

– Choose breathable materials: Cloth masks should be made from tightly woven but breathable fabric like cotton.

– Prioritize fit: Masks should fit snugly over nose and mouth without gaps but not be painfully tight.

– Adjust head straps: Ensure straps or elastic are loose enough to prevent skin irritation.

– Clean regularly: Wash cloth masks or replace disposable masks daily to prevent buildup of contaminants.

– Give skin breaks: Avoid wearing masks for overly long periods and give skin time to breathe overnight.

– Monitor breathing: Be aware of any worrisome breathing changes and adjust or remove mask if issues arise.

– Use caution if high-risk: People with respiratory conditions or anxiety should be extra cautious about overnight use.

– Don’t replace other precautions: Masks add protection but don’t eliminate the need for additional COVID-19 safety steps like distancing.

Signs of Problems Related to Overnight Mask Use

It’s important to monitor yourself or your child closely for any signs of breathing issues, skin injury, or other concerning symptoms associated with long periods of mask use:

– Shortness of breath, difficulty breathing
– Dizziness, lightheadedness
– Rash, skin irritation, redness, acne
– Face pain or numbness
– Headaches upon waking
– Excessive sleepiness or fatigue
– Discomfort sleeping, frequent waking

Remove the mask immediately and contact your doctor if any of these symptoms appear severe, worrisome, or persistent. Mild problems may resolve by using proper breathable masks, adjusting fit, and allowing skin breaks overnight.

Children and Masks Overnight

There are some unique risks and considerations when it comes to mask use overnight among children:

– **Suffocation risk:** The CDC recommends against mask use for children under 2 due to dangers of suffocation and strangulation.

– **Breathing concerns:** Children with asthma, allergies, or airway abnormalities may have more acute breathing issues with overnight masking.

– **Distraction and discomfort:** Masks may disrupt sleep more significantly for some children. Frequent fidgeting can reduce effectiveness.

– **Skin irritation:** Softer children’s skin may be more prone to rashes or irritation from extended mask contact.

– **Supervision required:** If masks are used on children overnight, parents should provide close monitoring for safety.

Consult with a pediatrician about whether benefits outweigh the risks for your individual child before attempting overnight masking. Proper fit, breathability, skin breaks, and caution are essential if pursing.

Alternatives to Masks for Overnight Use

For those who cannot tolerate mask use at night, some alternatives may provide similar benefits:

– Sleeping alone: Having your own room and bed can reduce COVID-19 transmission risks if isolating from household members.

– Air purification: Air cleaners with HEPA filters may reduce airborne allergens.

– Nasal strips: Adhesive strips that open nasal passages may ease some mild sleep apnea.

– Sleep position: Sleeping on your side rather than back can help with sleep apnea.

– Weight loss: Losing weight through diet and exercise can help treat sleep apnea for some people.

– Nasal dilators: Devices to open nasal valves may improve airflow without masks for mild sleep apnea cases.

– Avoiding allergens: Removing allergen triggers from the bedroom like dust mites, pet dander or pollen may help reduce overnight symptoms.

Discuss options with your doctor to find appropriate treatment alternatives if masks are not well-tolerated.

The Bottom Line

For most healthy people without significant underlying conditions, wearing cloth face masks overnight is unlikely to pose major risks. But some possible downsides include potential breathing issues, skin irritation, sleep disturbances, and a false sense of security against COVID-19.

People with respiratory diseases, children under 2, and anyone who experiences worrisome symptoms with masks should avoid extended overnight use or take proper precautions. Consulting your doctor for personalized advice is recommended.

With suitable masks, proper fit, and careful monitoring, masks may provide added overnight protection against COVID-19 and allergens for many people. But they should not replace other protective measures. Being aware of any concerning symptoms remains essential when wearing masks for extended periods.
