First thing: the article does not advocate against heating your home as most comments here seem to suggest. Quote: "this article is not a plea to get rid of heating systems altogether [..] for many of us, a heating system remains a necessity". Secondly I have experimented quite a lot this winter with clothing to reduce home heating requirements. I used to keep my home at 24C(74F) and wear short pants and short sleeves made of cotton. Now I keep the home at 20C(68F) during the day and 18C(64F) during the night. My heating bill is now half and I did notice I sleep a lot better at 18C then I used to at 24C. I wear synthetic form fitting long pants and sleeves thermal base layer and a loose synthetic robe on top of those. The base layer keeps more heat but more importantly evacuates sweat a lot better than cotton. The robe is what keeps most of the heat trapping air inside being thick but also air between it and the base layer. You can find a lot of material on the internet about layering clothes and what each layer should do. One mistake I used to make and the article seems to think so as well is that the base layer's role is to keep heat. I chose synthetic over wool for home because of the huge price difference and also the wear resistance. It's 10 euros vs 200 euros, I can wash it without care, I won't cry if they get stained with coffee, etc. I use merino wool when going out. After these experiments I plan to get rid of most of my cotton clothes and replace them with synthetic and merino wool, even for the summer. I can't believe how I put up with the humidity trapping cotton for so long. I am also interested to hear what other people experimented in this regard and their results.
