Trembling and shaking in your boots? If you don’t have any reasons to be anxious like exam or important work plan, watch out! That’s not good in any case, but shivering might be an initial symptom of hypothermia. It is logical for the organism to resist changing temperatures. When it dramatically falls, the person starts feeling cold. The body is trembling trying to get hotter. It is a good sign that your skeletal muscles are shaking when it gets too cold as it is a signal that your organism is fighting instead of giving up.
