Mask headaches and skin irritation: what studies report

Surveys of health-care workers and reviews of skin reactions show how common these problems were, and what dermatology bodies suggest, with dates and limits.

Anyone who wears a mask for hours may notice a sore nose bridge, itchy cheeks or a headache by mid-afternoon. This sheet looks at what studies actually measured, what dermatology and occupational-health pages suggest in response, and when the sensible step is to see a clinician. Most of the research comes from health-care workers during COVID-19, so it describes long shifts in protective equipment more than casual use.

As at 7 August 2024 (American Academy of Dermatology): the skin-care advice below reflects that page's last-updated date. The studies date from 2020 and 2021.

What studies report on headaches

A cross-sectional study of 158 frontline health-care workers in Singapore, published in Headache in May 2020, used a self-completed questionnaire. Of the 158, 128 (81.0%) reported new headaches linked to protective equipment, which in that hospital included N95 masks and protective eyewear. A pre-existing primary headache diagnosis (odds ratio 4.20) and combined equipment use for more than 4 hours a day (odds ratio 3.91) were each independently linked to new headaches.

Among the 46 respondents who already had a headache diagnosis, 42 agreed or strongly agreed that the extra equipment had affected control of their headaches. The authors concluded that most workers developed new equipment-related headaches or had existing headache disorders worsen.

The limits matter. This was a single-hospital survey that asked people what they perceived. The mask could not be separated from the eyewear, so it cannot say that a mask alone causes headaches, or how a lighter mask would compare.

A dermatology review adds one more clue. The systematic review in the Journal of Clinical and Aesthetic Dermatology (2021) reports that studies of N95 use for more than four hours showed a nonsignificant link (p = 0.053) with low oxygen and raised carbon dioxide, which it says can lead to headaches and chest discomfort. The review words this cautiously, and so should a reader.

What reviews report on skin

That same review collected 954 reported cases of skin effects from masks. The most common were itch (38.8%), facial indentation or ear pain (10.7%) and discomfort (9.4%). Among skin conditions made worse, acne accounted for 44 cases (4.6%), rosacea 14 and seborrheic dermatitis 9. Nurses and doctors were affected more often than other hospital staff, in studies that gave the detail.

Two terms are worth defining. Contact dermatitis is a rash where skin touches something that irritates it or triggers an allergy. Pressure injury is damage from a strap or nose clip pressing on skin for hours, and the review's own list shows indentation and ear pain among the most frequent reports.

What dermatology and health pages suggest

The American Academy of Dermatology's page 10 ways to prevent face mask skin problems (last updated 7 August 2024) recommends gentle cleansing and a fragrance-free, non-comedogenic moisturiser, skipping makeup under a mask, and avoiding new harsh products. It advises a snug but comfortable fit with no gaps, noting that a loose or sliding mask irritates skin and invites touching. For cloth masks, it suggests soft, breathable cotton on the layer against the skin.

On breaks, it suggests a 15-minute mask break every 4 hours, saying health-care workers have found this helps their skin. The JCAD review recommends 15 minutes every two hours in a safe environment, so sources differ on timing. The AAD page also says to replace a wet or dirty mask, and to wash cloth masks or discard disposable ones after one wear. See caring for reusable masks for washing, and fit and seal for sizing.

Two practical questions get only brief treatment in the sources: how to ease sore ears from elastic loops, and how to pick a mask that stays comfortable across a long day. The one concrete tip cited here is the AAD suggestion to alternate mask types with different ear loops. The JCAD review also cautions that skin protectants and dressings can change how an N95 fits, so they should be used carefully.

When to see a clinician

The studies above are surveys and reviews. They cannot diagnose anyone. As a general rule, a headache that is severe, keeps returning or does not ease should be raised with a clinician, as should skin that breaks open, blisters, weeps, or shows signs of infection such as spreading redness, warmth or pus. The AAD page says to tell a dermatologist if skin becomes irritated or an existing condition worsens under a mask.

Breathlessness deserves attention too. The NIOSH page on community respirators and masks (25 March 2025) says that wearing a respirator can make breathing harder, that anyone with a heart or lung condition should ask a doctor first, and that someone who has difficulty breathing or feels dizzy should go to cleaner air and remove it. The same page says to take breaks and drink water, since heat illness is possible. Where an employer requires a respirator, NIOSH says it should be used within a respiratory protection program, which in the US OSHA requires of many workplaces. The putting on and taking off sheet covers handling, and the types sheet explains how a respirator differs from a surgical or cloth mask.

This is general information. A person's own clinician or occupational-health adviser has the final word.

The short version

Surveys of health-care workers found headaches and skin reactions common after long hours in protective equipment, though those studies cannot show cause. Dermatology advice centres on a good fit, gentle skin care, clean masks and breaks. Severe or lasting headache, broken or infected skin, and trouble breathing are reasons to see a clinician.
