Is your stress written all over your face?
Famous for making necks tight, heads ache and stomachs upset, stress is becoming
a recognised trigger to redness, itching, burning and flare-ups commonly classified
as skin sensitisation.
And it’s a growing phenomenon: the American Academy of Dermatology reports up to 50% of the U.S. population experience some form of sensitive skin. Sensitised skin can be triggered in any person regardless of racial background or skin colour. Excessive exposure to skin-damaging environmental factors like chemical pollutants are frequent sensitisers. For example: Approximately 36% of the population in China has declared themselves as “sensitive”, a condition that may in fact be attributed to the high level of pollution in both rural and urban parts of this region.
What happens on the surface is stemming from a biological reaction in the body: inflammation. Inflammation is the immune system’s (immunogenic) response to infection and foreign invaders.
Just as irritating chemicals and excess exfoliation can trigger inflammation and red, stinging, itching skin, researchers recognise neurogenic inflammation (stemming from
the nervous system), is also triggered by
emotional and physical stress. It yields the same red, stinging, itching response, and
could even be responsible for severe skin disorders including psoriasis, rosacea and atopic dermatitis.
