Training in Heat and Humidity
Hi, Your podcast has changed the way I live and subsequently the quality of my life. Thank you. I live in Singapore. Many of your physical performance related episodes discuss training to HR, but I feel the impact of heat and humidity is underaddressed. I’m 55, and training in Singapore can add 10 bpm to my average HR during a run or bike. I’ve tested jogging a 10k in Singapore and six days later a 10k in Seattle while using the same pre run protocol: 10 bpm lower hr AND 30 seconds faster mile split. Similarly, I can easily hit my max HR in Singapore even though I am running or biking slower than I would elsewhere. I can only assume I put more effort into exercise in Singapore… with less gain. Or can I? I cannot escape the heat and humidity. How should I interpret my HR when training in what should be zones?. How should I adjust my training? Thanks for all your work. Mark
Disorders of Consciousness
Andrew Huberman, I just discovered your podcast about 6 months ago and I listen to it practically every day. And I absolutely love the information you provide! Unfortunately, I’m emailing on a much sadder note right now. My dad underwent what was anticipated to be a routine surgical procedure right before Christmas. However, during the operation, he had a cardiac arrest for an extended period of thirty-four minutes. He is now in either a minimal consciousness or a persistent vegetative state (it is difficult to determine which label applies to his condition). But he woke up a week and a half after the last surgery and regained consciousness for three days. After being reintubated for pneumonia he has not regained that level of consciousness. Recent MRI scans revealed minor strokes, which explain the loss of movement in his right arm, yet these findings, according to the ICU neurologist, do not explain his ongoing profound neurological impairment. We moved him to an LTAC (Long Term Acute Care) facility. The LTAC's neurologist has indicated a grim prognosis, suggesting there is little hope for recovery. This assessment has led my mother to consider withdrawing life-sustaining measures, which currently is a feeding tube, to allow for a dignified passing under palliative care (e.g., morphine drip). My inquiries to the LTAC neurologist about the potential for recovery, given the MRI results and Dad's brief periods of consciousness, have yet to yield satisfactory explanations. If his brain structures issues are minimal (which an MRI scan a month after the cardiac arrest proves) why is he not waking up? What is the mechanism for why someone would be persistently vegetative or minimally conscious if their brain structures are fine? If it is chemicals or an altered state of metabolism in the brain, could that be transient? Why would someone wake up and be significantly conscious for three days (a week and a half after the cardiac arrest) and then laps into a vegetive state, especially where no further brain structure damage occurred (as shown on a recent MRI). This uncertainty makes it all the more crucial to understand his condition fully before making irreversible decisions. Do you know of any person or group (perhaps in academia) I could talk to understand mechanistically what could have happened to my dad? Is there any literature I could read. I just read “Into the Gray Zone” by Adrian Owen, where he tells how he used an fMRI scanner to determine that almost 1 in 5 apparently vegetive patients are actually conscious and aware of everything around them. My brother and I are in search of clarity regarding what may have transpired, any additional treatment avenues, and the possibility of seeking a second opinion to better understand my dad’s condition and explore all potential options. My apologies. I know this may not be the best forum to ask this question.
Dopamine and Parkinson's
Dopamine is a pretty hot topic, and you share very useful techniques for supporting healthy levels. I'm wondering if there is any research that looks at techniques such as cold exposure for supporting early-stage PD. Also, I am interested to hear what the science says about exercise, dance, ping-pong, etc., and the progression of Parkinson's.
