How to reduce post-vacation drowsiness when returning from high sunshine exposure to mainly artificial light and low sunlight access
I love “getting away” to the south during the winter months in Canada when it is dark and cold. However, when I come back, especially in January, I get a vacation hangover. Incredible drowsiness, despite getting 8+ hours of sleep, low motivation and drive to get up in the morning when just a few days previously in the sunshine I would pop out of bed, run 5k, make breakfast, and tackle the day with tons of energy.
How much does fiber (insoluble and/or soluble) actually affect absorption?
If one is tracking macro/micro nutrients and calories, how much should one take into account the impact of fiber intake? e.g. does the fiber of quinoa decrease the absorption of protein from the quinoa? If so, would that same fiber decrease the protein intake of a steak? Or calories, other nutrients, etc?
Cold plunge and the effects on kidneys
Is it true that cold plunges have a negative effect on Kidneys and is it true that if this happens it makes us age faster by increasing wrinkles and increases hair loss? Supposedly there’s a limit of how much Kidneys can take and if so what is that limit? Tell us more how much in relation there is every time we do a cold plunge for our Kidneys. From another source of information they claim that the Kidneys don’t want to be cold. How much do the Kidneys have to do with our over health and aging?
Vertigo and tinnitus
Please consider an episode on vertigo (not dizziness), tinnitus and all things ear health related. I listened to July 21 on hearing and balance, but hoping you could expand more deeply on what vertigo is, causes, how to resolve it (if possible), and how to prevent it (if possible). And along those lines defining tinnitus and if there's anything supplement or dietary related that can help. And is there any evidence that this can be caused by COVID (as this is when mine started),. Thank you to all the folks that make Huberman Podcast. Such a valuable resource. And of course Thank you to Dr. Huberman!
