Why Seela is the future of activewear? Our products protect your health from every aspect.

When your heart rate is up, “you get vasodilation — vessels widen, and more blood, oxygen and nutrients go to the skin,” said Marnie Nussbaum, a dermatologist in Manhattan. “That’s the glow you see.” Your pores open up, letting in more of whatever is on the skin’s surface.



More or less all sportswear today are made out of synthetic fibres, as polyester or polyamide, raw or recycled. These fibres has great technical properties and low prices. But is there a hidden cost in garments made out of these fibres?


A study from Stockholm University made 2015 screening different textile materials that are common in clothing, like cotton and polyester. Their tests revealed the presence of thousands of compounds in the materials - and they especially looked at the ones that had skin penetrating properties and toxic characteristics. When it comes to polyester, the study showed that the concentrations of these chemicals were notably higher in their polyester samples compared to garments made of plant based source. For instance, they found an 800 times higher concentration of quinolines in polyester samples compared to garments exclusively made out of cotton. Quinoline is a chemical compound primarily extracted from coal tar and petroleum that potentially can have health-hazardous effects. There are also two other chemical compounds, benzothiazole and benzotriazole. The highest concentration of them was found in a sample made from 100% polyester. These two compounds that have been shown to have acute toxicity in various test systems and cause allergies and irritations. Benzotriazole was found to be mutagenic and estrogenic in aquatic organisms and they can bioaccumulate in birds, fish and invertebrates. They can also be absorbed by the skin. A transfer to skin experiment revealed that benzothiazoles are released from textile clothes, and that both compounds have been detected in urine samples collected from general populations. Even aromatic amines have been found in highest amounts in polyester samples. Aromatic amines are mainly used in the production of azo-dyes, can be absorbed by the body, and can increase the risk of certain cancers.


To sum it up, differences in the concentrations of these chemical components is related to the fibre type used in the garment, and higher amounts could be found in textiles manufactured from synthetic base. 


"In the past, I always had mixed feelings when I got dressed for my workouts. I knew about the hazardous effects from synthetic fibres but still needed their properties to perform at the level I wanted. Today I feel totally different. Getting dressed in Seela calms my mind and makes me feel strong physically. In Seela I become the best version of myself.”
