“Acute activation of the immune system (from exercise or sauna use for example) can temporarily reduce inflammation and the depression that can come with it. The segments brought to you by this episode of The Aliquot feature professor of psychiatry Dr. Charles Raison.”

“Since a driving force in the development of insomnia is change, especially change that affects relationships, employment, or family dynamics, Dr. Mason employs cognitive behavior techniques that help her patients identify what those changes are and develop strategies that promote, rather than hinder, sleep.”

“- Practical details like temperature and duration of sauna use, the difference between a dry, wet and infrared sauna, sauna timing, as well as other forms of heat stress such as steam showers, hot baths, and hot yoga.”

“In a crossover experiment with 12 healthy adults, six 40-second high-intensity cycling intervals increased circulating BDNF four to five times more than 90 minutes of light cycling. The BDNF response also tracked with the rise in circulating lactate.”

“Dr. Patrick describes increased shear as a possible way vigorous exercise can damage fragile circulating tumor cells; this is a proposed mechanism, not proof that a workout eliminates metastasis or treats an established tumor.”

“Exercise can improve blood pressure, insulin sensitivity, triglycerides, and fitness, but someone with high ApoB or LDL may still need targeted diet changes and clinician-guided lipid-lowering treatment. Mood is another major benefit.”
