Intermittent physical and environmental challenges, such as heat, cold, or fasting, trigger beneficial genetic stress response pathways that protect against aging and disease.

“these are all types of stress intermittent challenges that activate genetic pathways in our bodies. These are often referred to in science as stress response pathways because they respond to a little bit of stress.”

Biological stress such as exercise, fasting, and plant phytochemicals induce adaptive stress responses that enhance cellular resilience and overall health.

“The reason fruits and vegetables are good for our health is not because they are free-radical-scavenging things like vitamin E or C can help in certain ways, getting rid of free radicals. That's not the answer. The answer isn't that we want to swamp ourselves with things that sop up free radicals be”

Environmental hormesis involves providing the body with the right dose of challenge and recovery to improve resilience and function.

“So when you challenge those systems regularly with the right dose which I talk about in my book which is an environmental hormis allow it to recover and align that with a functional circadian rhythm you will improve function your health will improve and your overall quality of life will get better.”
