3. Become a Pack
Dogs, sea lions and numerous other creatures prefer to sleep in a pile with their pack. This is not just for comfort and social purposes; it is also the perfect way for everyone to stay warm.
Even if you end up sharing space with someone other than your family members after the SHTF, you will be able to more easily ride out a frigid night by adopting the pack type sleeping mentality. Cuddling together underneath thick blankets is one of the best ways to keep your body temperature up.
