Body Systems: The Basics

Wearable products may cause skin irritation, most often from the material (textile, film, fur) used to make the product. Individuals vary in their sensitivity to materials; some people are highly sensitive while others have no reaction. When severe, the irritation is called contact dermatitis. According to the Mayo Clinic, “contact dermatitis is a red, itchy rash caused by a substance that comes into contact with the skin. The rash isn’t contagious or life-threatening, but it can be very uncomfortable” (MayoClinic.org, 2017). Contact dermatitis from adhesives, plastic, and metals is likely to influence the viability of wearable technology. Contact dermatitis is divided into two categories: irritant contact dermatitis (nonspecific skin damage from friction and chemicals like detergents) and allergic contact dermatitis (poison ivy and fragrances). Allergic contact dermatitis tends to get worse over time. Irritant contact dermatitis goes away when the irritant is removed.

Contact dermatitis is dermatitis that occurs following contact of the skin with certain substances. Approximately 20 per cent of cases of contact dermatitis are of an allergic nature in atopic individuals and follow exposure to substances such as nickel, formaldehyde, plant and rubber products. The other 80 per cent follow exposure to irritant chemicals, such as those that are used in hairdressing, printing, catering and construction.

Additionally, workers in the MDF furniture factory may be exposed to formaldehyde and urea-formaldehyde resin, either by skin contact or because of the dust generally dispersed around the workplace. MDF dust generally contains 8%–18% formaldehyde and resins.4 This study found that workers in the exposed group, who performed daily tasks of cutting, polishing, drilling, and composing wood, developed symptoms of allergic contact dermatitis, which agrees with studies conducted by Priha et al.21 and Heikkilä et al.,22 who found that workers who performed these tasks in an MDF furniture factory had risks of exposure to wood dust during the process of sawing and sanding, or from the machines. Also, formaldehyde causes sensitization that may result in allergic contact dermatitis, as cited in the University of Pittsburgh Safety Manual.16 Another finding of this study was that the workers who spent more than 2 hour a day using chemicals at home, such as cooking, cloth washing by hand, gardening, dish washing, cleaning, and using chemicals suspected of causing contact dermatitis more than 2 h per day, and those who used bleach one to three times a month during housework, developed symptoms of contact dermatitis, as toilet cleaning liquids and bleach are skin irritants. Subsequently, this can contribute to symptoms of itching, rash, and skin swelling and an increased risk of allergic contact dermatitis.23–26

In several occupations, employees might develop cutaneous problems (i.e. dermatoses) in the work-place as a result of exposure to materials considered as irritants or allergens (Brown 2004; Sasseville 2008). In most of the cases, these work-related dermatoses correspond to occupational contact dermatitis (OCD) (Sasseville 2008). In turn, contact dermatitis constitutes an inflammation of the skin with lesions generally distributed on exposed parts (e.g. hands) (Smedley 2010; Sasseville 2008).
