Wearing naturally dyed clothes may boost health- 12-Aug-2013
London: Wearing particular colours may not only improve your mental health but also boost the body as it absorbs natural dyes, a new study suggests.
A researcher from University of Derby in UK is investigating whether garments dyed using traditional, natural colourings can directly improve physical wellbeing, as minute amounts are absorbed through the skin of the wearer.
Using different colours to stimulate positive moods, or colour therapy, is a known practice in complementary medicine.
The study by Dr Kate Wells, Senior Lecturer in Textiles at the university pointed out that many of the plant extracts once commonly used to dye clothing - such as indigo and woad (blue), turmeric (yellow) and henna (red) - would also have been used in traditional medicines.
She is looking at the possibility that, by wearing naturally dyed cloth next to the skin, people might directly absorb health-improving extracts.
"It's an area that's not really been studied before which is surprising given that a dye like indigo appears in many different countries and across cultures," Wells said.
"It is extracted from different plants through a process that is steeped in myths, superstitions and religious rituals, and which evolved over centuries.
"Around the world indigo was extracted from a variety of plants. In Europe it was the flowering plant isatis tinctoria (woad), in India indigofera tinctoria (indigo), in China and Japan it was polygonum tinctorium (Japanese indigo, a type of knotweed), and in West Africa the vine Ionchocarpus cyanescens.
"With people's interest now in handmade and sustainably made clothing, there is renewed interest in natural dyes. Woad is again being commercially farmed in England and to a greater extent in France, alongside other natural dyes. These are also being used in some cosmetics," Wells added.
The study was published in the Journal of the International Colour Association.
