Why do you get chills when you have a fever?

r/

Im sick today but my temp is only at 37,7 but I’m shaking as soon as I’m out of bed from the cold

why do we get chills from how cold it is when our body temp is goes up to almost 38 or higher?

    “The chills” is your body attempting to warm up, to get to the fever point it’s trying to reach

    It’s an immune response by your body. Your body is intentionally trying to raise its temperature to make itself less hospitable to invading organisms. The rapid muscle contractions generate heat.

    What we experience as “hot” and “cold” are based on the difference between our internal temps and external temps. Raising your internal temp raises your body’s reference point for temperature so the stuff around you feels cooler despite not actually being colder.

    Think of your body as an oven normally set to a standard temp. For an oven analogy – say it’s 350 degrees F. It maintains that – and all is well.

    All of a sudden, we get sick – our body turns up the temperature to 400 degrees F. Suddenly we feel cold – because our normal temperature is under where our body wants it to be. So we start shivering and shaking to engage our muscles to increase our temperature.

    A common misbelief is that a fever “kills” the germs- it does not, as a temperature that high would be incompatible with life. What the extra heat of the fever does is make the immune system more efficient.

    The chill feeling causes shivering, which is repetitive muscle contraction. That generates a lot of waste heat, which accumulates in the body and raises the internal temperature, just as shivering warms your body when you are too cold. Raising the body temperature helps fight infections by increasing your metabolic rate and immune system activity, and also by inhibiting the growth of micro-organisms.

    Your body mostly detects the rate at which it is shedding heat, not the ambient temp or your body temp. 

    When its cooler you’re shedding more heat so it feels cold. When you’re running a fever you’re also shedding more because you’re making more to sustain the fever.

    If your body temperature is only 37 degrees no wonder you’re cold

    The part of your brain called the hypothalamus serves in part as a thermostat.

    When something that can trigger fevers happens basically little molecules alert the hypothalamus that the temperature needs to rise. Then your brain basically sends out signals to the body to make it happen.

    One of the first responses is that peripheral locations constrict the blood vessels to focus on sending blood to the core which will raise the core temperature.

    As a result you feel cold because blood is shunting away from your hands, feet and the area close to your skin. Hence you feel cold.

    If your brain decides the temperature needs to rise real quickly then you may develop chills or “rigors”.
