What is a good way to warm yourself when it is cold outside?

Wearing warm clothing, such as sweaters, is an effective way to retain body heat and protect yourself from the cold. Layering clothing creates insulation, trapping heat that your body generates and preventing it from dissipating into the colder environment. This approach helps maintain a comfortable body temperature, especially in chilly conditions.

In contrast, consuming alcoholic beverages can give a false sense of warmth as alcohol can dilate blood vessels, causing heat to be lost more quickly from the body's core. Keeping an electric heater plugged in and on at all times may pose safety risks, including the potential for fire hazards, and may not be practical or energy-efficient. Staying completely still can reduce heat loss through movement but does not actively keep the body warm without additional insulation from clothing or heat sources.
