The present disclosure describes methods and devices for increasing human life span (longevity) via electromagnetic treatment. An array of electromagnetic emitters are positioned proximal to a subject. An electromagnetic wave generator generates electromagnetic fields having a predetermined set of parameters. Life span is increased by applying the electromagnetic waves to the subject through the electromagnetic emitters.
