I remember from the winter period in 2012/13 that you can buy some very thick blankets to keep warm in bed. Getting up in the morning and feeling cold a bit with your body adjusting to the temperature after some time can keep you healthy and strengthen your body. I lost weight since then and made me look slimmer after returning to Europe. I also did not eat any meat and kept to vegetables instead the last time although I am not a real vegetarian. This will also help if you suffer from diábetes.
