Suddenly, an icy cold creeps up the spine, teeth begin to chatter uncontrollably, and even the thickest woolen blanket doesn't seem to warm you anymore. Anyone who has experienced severe chills knows how unpleasant, exhausting, and sometimes frightening this condition can be.

This article sheds light on the medical background, provides practical tips for relief, and explains when a doctor's visit is essential.

When and why do chills occur?

To understand the phenomenon, we need to take a brief look at our brain. More specifically, at the hypothalamus, which acts as our internal thermostat. If viruses or bacteria enter the body, the immune system releases certain messenger substances (pyrogens). These travel to the brain and signal: „Attention, we need more heat to kill the invaders!“

The hypothalamus then raises the setpoint for body temperature. Conversely, for our body, this means it suddenly feels „too cold“ because the current actual temperature is below the new setpoint. To quickly compensate for this difference and Regulate body temperature To be able to, the organism resorts to a drastic measure: it generates rapid Muscle contractions due to cold sensation.

The uncontrolled trembling of the musculature produces massive thermal energy, which heats us from the inside out. Thus, the strenuous shaking ultimately helps to Stabilize the body's heat balance to be able to, until the saving fever is reached.

In addition, psychological factors must not be overlooked. The Connection between stress and shivers is medically well documented. In cases of extreme emotional distress, shock, or a panic attack, the body releases large amounts of adrenaline. This leads to a severe narrowing of the blood vessels in the skin – we become pale and start to tremble uncontrollably, without any pathogen.
