The Biological Mechanisms Behind Fever and Chills
Fever and chills are not just random symptoms. They are part of the body’s defense mechanism. The hypothalamus plays a key role in this process, acting like a thermostat to adjust the body’s temperature.
How the Body Regulates Temperature
The hypothalamus is very sensitive to temperature changes. It starts cooling down or warming up the body as needed. “When the body’s temperature rises, the hypothalamus makes you sweat to cool down,” it explains the balance in temperature regulation. On the other hand, if it’s too cold, it makes you shiver to warm up.
When you get sick, the hypothalamus raises your body’s temperature. This makes it harder for many pathogens to multiply. It helps your body fight off the infection.
Why Symptoms Often Intensify at Night
At night, the body’s natural rhythm affects the immune system. Cytokines, which fight infections, are more active at night. This can cause your body temperature to rise, leading to fever and chills.
Also, the body’s temperature can fluctuate during sleep. This can make fevers worse at night. You might wake up sweating or feeling fever chills at night. This can really disrupt your sleep and make you feel worse.
Many people experience chills and sweats with fever. This is the body trying to adjust its temperature to the new set point. It’s called cold shivers hot sweats.
