Science and value of DNA health tests
How useful is it get your genes analysed? How seriously must the results be taken? I understand that certain gene propositions can be switched on by lifestyle choices. Can they also be switched off, once they have been switched on? I recently got my genes analysed . Now I am challenged to interpret the results and draw actionable conclusions from it. For example, according to the test I have a moderate risk of getting a gluten intolerance. Does this mean I should completely avoid eating gluten containing foods? Also, most of my IL inflammatory genes are marked as of of high impact/risk. I already lead a fairly healthy lifestyle, so should I not worry about these variations? Thank you so much for your great work!
Physiological benefits/detriments of exercise in hot vs cold weather + morning vs evening
Hey Doc, My question is in relation to Episode 4 of your guest series with Dr Andy Galpin and your discussions around SMART Goals and "Defenders". Listening to your discussion made me realise that I have structured my training program to account for fluctuations in daily weather patterns and time of day. For example, I have noticed that the results of the same daily 80 min outdoor Zone 2/3/5 (walk/run/sprints) cardio session I do, can be significantly impacted by two factors, the time of day and the temperature. When doing this same exercise early morning vs early evening, the evening will see me achieve a significant increase in results across Max Heart Rate, Heart Rate Average and Calorie Expenditure. Similarly, when training during days of increased temperature (generally mild humidity), I see a similar increase in results, though in this scenario my cardio recovery time marginally (but noticeably) decreases. These effects are also increased when the 2 factors are compounded. So my question is in two parts: 1. What is happening physiologically for the "effectiveness" of my training to seemingly be so significantly improved when training in the evening/heat? And, 2. Which is more detrimental, training in the morning with what seems to be a lower efficacy or training within 6-8 hours of sleep with a what seems to be a higher efficacy? Many Thanks!
Calorie burn during sauna...
Andrew, is there any data on what the calorie burn is during a sauna session for those of us that track our calories? My heart rate can hit 140 with enough duration and heat, but I expect it's not the same as running and having a similar heart rate. On the other side of the spectrum I don't expect it's completely passive. I've been unable to find any definitive data on this question.
