Rethinking Laundry for the Planet With Dr Holly Kaye Smith (430) [REPEAT]

Most of us throw our clothes in the wash without a second thought, but what if that habit is doing more harm than good? In this episode, Dr. Holly Kaye-Smith, social change expert and communications specialist, challenges the way we think about cleanliness, climate action, and everyday laundry. From surprising stats (over 90% of washed clothes aren't even dirty!) to the hidden environmental cost of every wash cycle, we dive into the myths, microplastics, and mindsets that shape our laundering routines. Holly shares practical refreshing techniques that save water, and why she recommends everyone have a "rewear chair." Connect with Dr Holly Kaye Smith on Linkedin Instagram - Youtube -
