Relation between mouth breathing and airway infections and/or sympaticus activation

What are the scientific evidens on airway infections and too much symphaticus activation when you are full time mouth breathing. Stine, Denmark

Time managment and focus

I am certain this question has been answered in several episodes but I am curious about a statistic that I have read in some time management articles. I ascribe to your information about circadian rythms, exposure to sunlight, sleep cycles, and more. I have become much more productive and satisfied by applying information that I've learned here. I have read a statistic in several articles by other authors: "It takes about 23 minutes to get back into a state of flow" when distracted or pulled into other things mid-task. Is this true? I also have read as people age it can take longer--I am 62 and have noticed that it takes me longer to return to a task or even remember where I left off. I would love to harness this information to use to change some of the work processes at my job. There is an expectation in my work environment that Microsoft Teams and Outlook are to be attended to throughout the day, which I think is detrimental to productivity. I also think Teams is now "overused" in the work ennvironmennt as a way to share information. It is impossible to respond to all the data that is being shared by so many people. It would be better if the organization instituted a better way to use Teams and Outlook--like allowing for Teams/Outlook-free chunks of time. I'm saying this because for every email or teams message that needs prompt attention, it prolongs whatever task I am working on. Sometimes it takes me all day to get something done because I've been interrupted so much. I loved Dr. Kay Tye's method of addressing email! I felt very validated, because I decided I can't make other people's emails my priority. There are other ways to impart important information. And quite frankly, I believe that it is not possible to get everythihg done. I have come to accept that not everything will be done or done perfectly. So I guess my question is: Is this widely quoted statistic correct? Does it take about 23 minutes to return to flow after a distraction? And could you do a podcast about time management? I know that the answers about attention, focus and the best ways to schedule tasks can be found in podcasts about brain health, dopamine, attention and focus. Can you do a podcast from the perspective of time management? Thank you. I realize that a lot of this information can be found in several episodes. I love you podcast series, which is why I'm a subscriber.

Not sweating in the sauna (or just about anywhere else)

I'm an endurance runner who practices cold and heat exposure, largely following the exposure principles you've shared in your podcasts on those topics. I've never been a big sweater—even when I'm training hard in summer—but since implementing sauna practice, I have barely shed a bead of sweat. Is this... normal? Worrisome? If the latter, is there anything I can do do ameliorate it? For context: I do about 11 minutes per week of submersion in a cold river (hooray for New England winters). I have primary Raynaud's, and have noticed that my fingers and toes have become much more cold adapted since starting cold exposure about about six months ago. I'm newer to heat exposure. For the last month, I have been doing two-three rounds in an 185-190 degree sauna at 10-12 minutes each. It's unpleasantly hot, of course, but I never sweat during a session—not even when I stay in for upwards of 15 minutes. I'm confused about this, and also wondering if my body's historical response to cold (Raynaud's and how it relates to my core temperature regulation) might have something to do with this. I know that repeated sauna exposure can teach your body to sweat better, but what about the folks who come out dry and fresh? Is there hope for us? Should we even be concerned about it?

TBI from mutation of CACNA1A gene

Is there a way to reverse TBI in the hippocampus caused by a status epilepticus seizure that lasted for 5 days caused by a genetic mutation of the CACNA1A gene?

Skinny fat and body re-composition

Hi, I would love to hear your science-backed thoughts on those strruggling with getting rid of skinny-fat body composition. What is the ideal way to approach this as a woman in her 30s? Should I focus first on losing weight (will involve considerable muscle loss as Dr. Norton also explained in his episode) and then focus onmuscle building (eating enough and stregth training)? What would be your protocol or just any tips on many people with sedantary lifestyles who look thin but underneath their t-shirts are hiding a significant amount of belly fat? I know this question has been asked many times on AMA but I don't know if it has been answered! Thanks for all you do and making science accesssible to us all!
