I've found that exercise helps. I try to jog and lift weights regularly, but usually I exercise for a few months and stop for a few months. When I don't exercise, I notice I'm a lot more tired and feel significantly colder than when I work out. Also, if I don't eat enough food, I feel tired throughout the day as well. It makes me feel like I can't focus or think, but then I'm fine after I eat. Maybe it's because I'm skinny.
