Coldness affects me. Slow metabolism from being ill means my body can't make as much heat as it should and with the generally wonky brain I'm more likely to get grumpy or lose ability to do anything much when even a bit cold. It's been snowing this week and the usual advice is to put on an extra jumper, which is all well and good for arms and torso but not so good for the legs. Ladies can put on tights but those went out of fashion for men a few hundred years ago. So I got some thermal leggings from an outdoors shop and have taken to wearing them most days. It all helps.
