Clothing developed out of utility and ability at least 200,000 years ago. Initially naturally and readily available plant and animal products were used. Eventually the technology to improve those products developed into the clothing and textiles industry we know today. Clothing most likely had no aesthetic purpose initially; but was a barrier from weather, minor trauma, UV damage, bugs, parasites and even microbes (though they may not have realized it at the time).
Over time, as societies developed and communities evolved, people began to use clothing to communicate. It was used both as an art form and as a way to identify status in society. Personal protective gear and athletic/sportswear, both rooted in utility, have influenced fashion. However, in all of our self expression and trend following, there are health risks that may outweigh the general benefits of some clothing.
Tight underwear have been associated with lower sperm count in men, increased risk for jock itch and other dermatoses in both genders, bacterial vaginosis and vaginal yeast infections in women, and urinary tract infections (mostly in women). Thongs and G-strings are obvious culprits, but bikini and brief style underwear are generally problematic due to anatomic and physiologic reasons to both sexes. However, if going without underwear for the reasons above; a skirt, sarong or kilt is healthier for the crotch than pants. Friction from clothing against the body can be irritating.
Tight clothes and athleisure gear can increase heat and moisture retention, increase friction of fibers against skin, limit mobility and create neuropathic pain. Some fibers like nylon or lycra may exacerbate this problem. Wearing clothing too tightly exposes skin to detergents, fabric softeners, irritants, microbes or dyes that may be in or on those clothes. People are commonly sensitive to some fabrics, wool for example, so wearing it closer to the skin may be more uncomfortable. On the other hand, compression is appropriately used to treat various vascular and lymphatic complaints- usually to reduce swelling.
Corsets can improve posture and reduce the pressure that a bra puts on the shoulders, stabilizing the back and reducing some pain. If used for waist slimming, as they were for centuries, they could cause or worsen gastrointestinal problems, bowel pain and pelvic floor prolapse. They can also cause rib distortion and injury to internal organs. They can certainly lead to restricted depth of inspiration and associated respiratory complications. Long term use, may reduce core tone as the corset is relied upon for stability. Body shaping garments can have similar effects.
Bras have shortcomings as well. Though not known to be associated with breast cancer, underwires and bras in general are a frequent cause of discomfort and a mass effect in breast. Ill fitting bras can cause breast pain, back pain, or shoulder pain. They can cause the same problems that other tight fitting clothes do and can cut into the shoulders or torso, leading to skin compromise. A well fitted bra is worth the investment.
Fibers found in elastics can also be irritating. Thread tourniquets or elastic band tourniquets can form due to friction within a garment. This usually occurs in small children – they present with irritability and a swollen finger or toe (or genitalia in some cases). Loose fitting clothing is generally better except that wearing loose clothing to bed has been associated with higher risk during a fire (especially in children). Some fabrics may be associated with worse burns than others, but fabrics containing halogenated fire retardant materials may be associated with reproductive and neurodevelopmental toxicities.
Walking barefoot causes athlete’s foot through direct contact with the causative microorganisms. At the same time wearing footgear that doesn’t allow for ventilation increases moisture and heat entrapment and will exacerbate athlete’s foot by contributing to skin breakdown and providing a favorable environment. Footgear is important protective equipment, but it is also important to rotate frequently and occasionally take breaks from entirely. High heels and platform shoes can lead to serious musculoskeletal lower extremity and back injuries either chronically or acutely. They can also lead to falls. Tight toed shoes and gravity can worsen bunions; lead to corns and calluses, nerve pain, or bony distortions.
Buttons, beads, sequins, zippers, strings and cords can be dangers as choking or strangulation hazards. Anything not well affixed to the garment (or any jewelry) can be a choking hazard to a child. Zippers, beads and buttons may all be made from metals to which people are sensitive (like nickel). Kids also put buttons, beads and sequins in their noses, mouths, ears, butts and vaginas. These, as well as earrings and other jewelry, can also lead to problems such as infection, inflammation or obstruction. Rings on fingers have led to serious hand injuries, including skin avulsions and amputations. Zippers lead to numerous penis and scrotal injuries yearly from using them appropriately, but absentmindedly.
There are, of course, psychosocial consequences to the clothes we choose. These are subtle and subjective. The way we present ourselves affects how people interact with us: whether they even choose to interact with us sometimes. They can make us feel like part of a group or like outsiders: can be the cause for our acceptance or rejection relative to who we are and who we are with. There is no doubt that fashion can affect our happiness. Indeed there are many tales throughout history in which the outfit, uniform, disguise or costume makes all the difference. While they can promote hygiene and protect us from the elements, we should not overlook the common ways our wardrobes could threaten our health and safety.
