How to stay warm indoors in winter?

Simple! Turn on the heater.  ok, firstly you need to keep your feet covered. When your feet are exposed to the cold, you entire body loses heat and you will feel like a block of ice. I suggest you wear socks at home and make sure your feet are covered. If you have a fire place then start a fire and sit in front of it. This ought to keep you warm and snug. Hot piping cups of tea are an excellent way to keep the heat. Keep the kettle on boil and stay warm.  Hot Chocolate also helps.
