SEVERE PULMONARY HYPERTENSION Please Help

Hello I am a 39yr old female who recently found out that i have severe pulmonary hypertension with severely elevated pulmonary artery pressure of 79mmHg. I am wondering if you have any insight on ways to reverse this condition and our ways to make it manageable to live a normal life. I have an infrared sauna and cold plunge and also wonder how to safely incorporate that into my daily routine. I was a very active mountain biker and hope to get back to that but not sure as I cant really do anything but rest at the moment. I have past drug and alcohol use and am not sure if that is the cause but I recently got married and I'm not ready to give up. There doesn't seem to be a lot of positive information out there but any insight or knowledge you have could help and its worth a try. Thank you so much

Tin Man vs Lots Wife fluoride

In your research on fluoride, did you find any definitive data comparing stannous fluoride vs sodium fluoride, in particular for tooth paste?

Exercise Intolerance! PLEASE HELP!!!

I'm fatigued chronically but I love to exercise because I desperately need it both physically and mentally. On days that I'm less fatigued, I embark on a 45 to 60 minute exercise that can involve jogging, strength training, weight lifting, biking, swimming, etc. If there is any kind of intensity to my exercise I have a severe post-work out crash! This includes hot flashes (feeling very hot/warm in the head and forehead area), severe fatigue to the point that I have to lay down for couple of hours and sometimes even flu-like symptoms. I've been able to get rid of the hot flashes by drinking a lot of water during and after work out along with some electrolytes. However, the severe fatigue episodes (crashes) remain no matter how much I hydrate. Is there a protocol that I can follow to cut down on these debilitating episodes after my workouts??? This would change my life. Your attention is much appreciated!

Five Second Rule

Is there any science behind the "five second rule" (food okay to eat if it doesn't stay on ground for longer than 5 seconds)?

Static stretching downsides and stretch-induced force loss

I saw a paper in Springer (https://link.springer.com/article/10.1007/s40279-017-0682-6) talking about downsides of static stretching. I asked Scholar GPT to summarize some of the research: “Yes, stretch-induced force loss is a recognized phenomenon in muscle physiology. It refers to the reduction in maximal force production by muscles following an elongation or stretching. This can happen without sarcomere disruption, indicating that the mechanisms behind force loss are not solely due to structural damage but may also involve changes at the molecular or cellular levels in the muscle tissue. Studies have explored various aspects of this phenomenon, including the effects of inhibiting cross-bridge cycling, the protective role of specific proteins in eccentric contractions, and strategies to mitigate force loss after stretching.” Thoughts on this? Do you stretch or do yoga, or do you find it to be problematic?
