Probably a heated blanket. Recalling when my mom used to put the warm laundry on me and it was so cozy warm. I also remember a time in the hospital while I waiting in the ER to be admitted. It was so cold. I tried covering myself with my coat but it wasn't enough. I asked for some blankets and they brought me some which helped but not a lot. When I finally got admitted and they put me in my bed the blankets had been heated and it was soooo much better.
Fires, hot drinks, dressing warm, hot soup, blankets at home and extra layers outdoors .. i used to have larger sized pants that i would wear warm funny pajama pants under.. it was cozy 😁 but i was dressed normally over them ☺️
