>What is cold fever and why does that happen?
“Cold fever” isn’t a thing. When you have a fever, what’s happening is basically your body’s thermostat is dialed up a few degrees. Because your body’s temperature is below your “set point,” you interpret that as ‘cold.’
The reason we get fevers is because a higher body temperature both increases the effectiveness of your immune system and negatively affects bacteria and viruses infecting you.
Fever changes the body temperature. This change can destroy some causes of illness. As the brain “turns on” the ‘we need to be warmer” switch, you feel cold because you are below your target temperature. It’s the physiological response because you’ll get warmer if you do more to retain heat.
Chills without a fever are the same cause, just out of order. You may never actually develop a fever. But your body thinks you need to be warmer because you aren’t warm yet.
Your body has a built-in thermostat that helps control your temperature. When you go down with a fever, it’s like your thermostat is “set” up a few degrees to help fight off the infection (since heat kills bacteria/viruses). But the downside is, your body temperature doesn’t catch up immediately before the thermostat raises, which is why you get chills when your fever starts. This then gives you the sensation of being cold, making you want to hide under a blanket, sip hot tea, or do other things to quickly bring your body temperature up to the “set” temperature. You then experience shivers, which are your muscles working to generate heat by burning stored energy
