What are hormetic stressors?

Hormetic stressors are agents or conditions that can be beneficial in small amounts but become harmful if experienced in excess. These stressors cause the body to adapt and improve its resilience through a response known as hormesis. Examples of hormetic stressors include mild physical exercise, caloric restriction, hot and cold exposures (like saunas and cold plunges), and potentially certain foods. Hormetic stressors work by providing just enough stress to the body to stimulate adaptation without causing significant harm or disruption 1 2.
