The use of N95 mask increases the effort in breathing and may cause discomfort, tiredness or headache. As some people with chronic lung disease, heart disease or stroke may already have reduced lung volumes or breathing issues, they should stop using a N95 mask if they feel uncomfortable. They should consult their doctor as to whether they can use the N95 mask.

The N95 mask is not suitable for pregnant women and children.

Persons with chronic lung or heart conditions who feel uncomfortable when wearing the N95 masks should stop doing so and consult a doctor before carrying on.

Note: Persons who are not feeling well should seek medical attention
