Formication is a sensation linked to stress and fatigue

Question asked:

“Imagine feeling like tiny insects are crawling on or underneath your skin, but nothing is actually there. That unsettling sensation is called formication. It is a type of false sensory experience where your nervous system generates a crawling or tingling feeling without any physical cause. It can be linked to high stress levels, extreme fatigue, nutritional deficiencies, or sudden changes in body chemistry. Supporting consistent sleep, balanced nutrition, and effective stress management habits are lifestyle practices that may help reduce how often these uncomfortable sensations occur.”
