What Makes You Feel Colder When Your Body Is Hotter? It's actually a normal physiological response. As soon as your brain shifts its internal thermostat to a higher set point to fight off an infection, the rest of your body goes to work trying to generate extra heat to meet that higher temperature goal.
Even if you have a high temperature, you might actually feel cold and begin to shiver. Your immediate reaction may be to huddle up under lots of blankets to feel warm. But even though you feel cold, inside your body is very hot. You will generally start to feel better when your temperature comes down.
Bundling up too much can make it harder to reduce a fever. If you have chills, try wearing a single, light layer and using one lightweight blanket. If your temperature's over 103ºF, let your doctor know. You may have the flu or another infection, so get checked out to be sure.

As part of the fight-or-flight response, you may experience a sudden temperature change, Dr. Merrill says. That's because another part of the brain involved in anxiety is the hypothalamus, which regulates body heat. Because of that, you could have chills, feel drenched in sweat, or weirdly, both at the same time.
In addition to shaking or trembling, other typical forms, according to calmclinic.com, include arm or leg spasms, cramping or longer or slower shaking than usual. Freezing hands and feet. Stress and anxiety can decrease your circulation. As a result, your hands and feet may feel icy.
They are most often associated with a fever. Chills are caused by rapid muscle contraction and relaxation. They are the body's way of producing heat when it feels cold. Chills often predict the coming of a fever or an increase in the body's core temperature.
The bottom line. Whether or not you choose to break a fever is up to you. While a fever can make you feel low, there might be good reasons to let a fever run its course. If you do choose to break your fever, antipyretic medications are effective — but remember, they won't treat the infection that's to blame.
How are chills treated? Layering clothes or getting to a warm place can make cold chills go away. You can also drink hot chocolate, coffee or tea to raise your internal body temperature. If an illness, infection or another health problem causes chills, treating the condition should get rid of the symptom.
Move Your Body
If it's too cold outside, hit the gym, or just do some jumping jacks, pushups, or other exercises indoors. Not only will it warm you up, it helps build and keep your muscles, which also burn calories and make body heat.
If you just can't warm up, it could be a sign that you need to drink more water. "Up to 60% of the adult human body is water, and water helps regulate body temperature," Moon said. "If you're adequately hydrated, water will trap heat and release it slowly, keeping your body temperature in a comfortable zone.
Without enough B12, you might not have enough healthy red blood cells to move oxygen around your body (anemia). That can leave you shivering and cold, especially in your hands and feet.
Can low vitamin D cause you to feel cold? Instead, vitamin D deficiencies typically result in rickets and other bone deficiencies. [10] While these conditions can lead to feelings of coldness, they don't seem to play as direct a role in thermoregulation as the B vitamins.
