>>1694570>is it really that easy? yes, your neck has a lot of blood vessels that regulate heat, which is why they'll place ice packs there first if you're experiencing heat stroke. Same logic in the winter, placing a heat pack there lets you warm up your blood and core temperature extremely efficiently.
>my shivers get bad, i was wearing a jacket and boots in IDK maybe 40F and tried to nap outside and i started shuddering after 30min.are you sweating out when you're hiking? you should learn to layer/delayer properly so your clothes don't get soaked, because that will make you lose heat extremely fast
>solar powered warm coil to stuff in a shirt, solar panels are 20% efficiency so its like 20% of the sunlght straight into ur chest for a whole nightanything electric or battery powered turns to shit in the cold. Plus winter has the least amount of sunlight. Just pick up a few disposable handwarmers and try those out first
