Episode notes

ADVICE

Build Fitness For Medical Resilience

Maintain cardiorespiratory and muscular fitness across life; Dawn credits lifelong fitness with preserving her survival capacity during cardiogenic shock.
Prioritize exercise early to build reserve that protects against severe illness.

ADVICE

Train Smart After Transplant

After transplant, train progressively and include exercise cardiology oversight; expect altered heart rate responses due to denervation and use catecholamine drive early.
Combine smart training, sleep, nutrition, and yoga to rebuild capacity safely and hit goals like a marathon.

INSIGHT

Lifestyle Medicine Underpins Integrative Care

Integrative medicine complements conventional care by adding evidence-backed lifestyle, mind-body, and supportive therapies without replacing standard treatments.
Lifestyle medicine (diet, movement, sleep, stress, connection) should be foundational to all cancer care.
