8. Wear more sweaters
While you’re drinking hot tea to warm up, are you in a t-shirt or a sweater? Bundling up in layers not only when you go out but also when you’re home can help you keep your thermostat set lower, keeping your energy bills under control. Invest in some warm wool sweaters — or grab the ones that have been hanging out in your closet waiting for you. To feel even toastier, don a turtleneck, some thick socks, and perhaps even a scarf, too.
