Alternative Peri/menopause support

Loved your episode with Dr. Mary Claire Haver, thank you so much for that wealth of empowering knowledge. Just knowing what causes symptoms somehow makes it easier, not to mention all the possible medical solutions that she spoke about is also incredibly helpful. Wondering if there could ever be an episode with other non-medicinal tools to deal with perimenopausal symptoms, especially mental issues like brain fog, depression, etc. ADHD like symptoms were mentioned in the episode, would tools for trying to improve adhd also be equally useful to help against perimenopause symptoms? Meditation? Supplements? Dopamine protocols from you dopamine episode? Thank you again for the fabulous podcast, I cannot express my gratitude enough for the help you are offering for free to help women and men navigate this Rocky Mountain range of a hormonal landscape. It is life changing.

Hydrogen Water Bottles

These range from $30-$300. Is there anything to them worthwhile? If the claims are true, it would be an easy protocol to introduce. Why is the price variance so large?

Eye lids closed or eye protection

I am 76 years old using a full body coverage red and NIR combo lamp (Rouge brand) 6” away from my body for 6 minutes on the front and then 6 minutes on the back for 6 day each week. If I keep my eyes closed for the 6 minutes when the bulbs are 6” above my face will the NIR penetrate into my eyeball? Is this harmful? Do I need eye protection.

Any correlation between Blood type and Diet?

I have heard and read a lot of critics regarding adopting type of diet/nutrition to persons blood type (A, B,AB,O) as I believe initially proposed by a book that came out in 90s “Eat Right for your Type”. Surprisingly I also know first hand from close family including my mother that have been following these recommendations maybe not strictly but on/off and could swear they can feel the difference. I’m aware this could also be placebo effect but is there any scientific evidence based study regarding this topic? Is it all pseudoscience? What is your point of view? Dr Huberman you are such a beacon of light in the science community and probably the only few opinions and views I trust!! Thank you for everything!!
