To stay warm during cold winter mornings at home, you can start by wearing warm clothing such as thermal underwear, socks, and a cozy sweater. Using blankets or a heated blanket on the couch or bed can also help retain body heat. Keep your indoor temperature comfortable by using a heater or turning up the thermostat if possible. Drinking warm beverages like tea, coffee, or hot chocolate can raise your core temperature. Additionally, sealing drafts around windows and doors with weather stripping or curtains can prevent cold air from entering and keep warmth inside.
