    190 – Zone 2 Running: when less exercise might count for more

    Are light runs (Zone 2 runs) better than heavier workouts? Sophie goes on a semi-manic tangent in her most enthusiastic episode yet to answer whether less intense exercise might actually help your fitness level, aerobic threshold and mitochondrial efficiency. Also, Chris tells a funny marathon story and a viewer question tries to fact-check to the fact checkers on whether walking and running burn the same amount of energy.   Become a supporter of our show today either on Patreon or through PayPal!

    186 – Pink Noise

    Pink noise claims it can boost your memory, help your sleep, and treat your ADHD. But how it's studied in a sleep lab is very different from passive listening all night long. Chris and Sophie dive into the evidence to figure out if the influencers pushing pink noise for sleep got it right or if they're simply dreaming.   Become a supporter of our show today either on Patreon or through PayPal!

    185 – Lipoprotein(a): the cholesterol you never heard about until recently

    Lipoprotein(a) or Lp(a) is suddenly all the rage because several drug companies are working on medications to lower this previously resistant form of cholesterol. Almost entirely genetic, unaffected by diet or lifestyle, it has numerous studies linking it to heart disease and aortic valve calcification.
