How to increase body temperature?
Your body temperature is very finely coordinated by a complex set of systems and it is set at a point that is best for your body and the processes occurring in it. Have you measured your temperature before? Because if you have temperature within the normal range than increasing your body temperature would be stupid and pointless. Normal oral temperature is about 98.2±1.3 °F. The way to increase your temperature would be to increase your metabolism, which will be coupled with several side effects including weight loss at the very minimum. This will be similar to people who take pills to lose weight, which work by increasing their metabolism and if you haven't noticed, most of those pills are made illegal a few years after they come out because of all of their side effects. If you're still interested, (though I don't think this is a good idea), the following are supposed to increase your body temperature: bitter orange, capsicum, ginger and caffeine. PS. You wouldn't be able to increase your skin temperature without increasing your core temperature. Skin temperature only rises when core temperature rises, causing heat to be carried from the core to the skin, where it can be lost.
