I am not ready for all this cold weather, but I have a few suggestions. First, as a heat pad for me, I created rice bags. Small ones for my hands and feet, a large one for my back and legs .
Warm winter gloves and a warm winter coat. I broke down last year and purchased a goose down coat; boy, is it warm!
If you are not good at sewing a simple rice bag is made by filling a knee high sock with rice and then tie the end. You could use a pretty ribbon to tie it with then place in the microwave oven for 2-3 minutes. You may have to experiment to get the right temperature for you. Also most big chain stores carry hand warmers that you open, shake and they get hot. The warning to these are they get very hot and can cause minor burns on sensitive areas.
The thing I enjoy about the rice socks is that they cool off through the night and there is less likelihood of causing severe burning as electric hot pads. Or for the wires to become trapped around a person.
Nowadays you can also get heated sheets for your bed; I have night sweats so I don't like those but many people do
Does anyone else have suggestions for this chilly weather survival?
