Comment of the Week

“Sun exposure – totally depends where you live. Here in New Zealand you can get seriously sunburnt in about 10 minutes in summer between the hours of around 10am – 3pm, especially if you are pale. You can actually feel the sun burning your skin immediately. I NEVER sit directly in the sun and don’t go into the sun without sunscreen and a hat. We have the highest rates of melanoma in the world.”

  1. The older I get (68) the more I become a morning person. It’s working well for me as I do 2 to 3 fasted workouts each morning. Added that 3rd workout, hiking, after gaining 8 ‘covid’ pounds only to lose 20 since then.

  2. Beginning to wonder just how much time, effort, and money these “experts” are going to waste trying to make plant mush taste like meat

    1. It’s ironic, to put it lightly.

      Europe has banned meat from animals treated with Hormonal Growth Promotants, despite the fact that HGPs are chemically identical to the natural hormones (which these artificial meats are NOT) and that they are produced via the same processes that are now being considered acceptable for manufacturing fake-meats.

      Regardless of what you think of HGPs and manufactured foods, the double-standard should be obvious.

  3. Have loved your blog for years and it has changed my life for the better. Though the covid/obesity article may be true, Swprs is a known pseudoscience website. My skeptical radar went off like crazy on this website.

    1. I’ve learned this past year that a lot of sources that I used to trust have an incredible pro-corporate bias. At this point I’m not at all concerned with where relevant information appears as long as the data is good or the hypothesis has some merit.

    2. “Known” by whom? I’ll bet you anything that the “whom” would also identify MDA as a pseudoscience website.

  4. I detest mornings and have always been a night owl. My favorite shift was from 2000hrs to 0400hrs. I felt healthier and was more active. As someone whose day now starts at 0500, not so happy but is the real world reality.

  5. I grew up in Kansas. Not much of a chance for ocean swims there! Then I joined the USAF and oh my did I love swimming in the ocean! Nothing better than a 3 mile run and then a nice long swim. Those ice cold waters can be amazing.

  6. I like your email newsletters and your one about jumping in the ocean hit home. Though a planned trip is necessary, getting to the ocean is something we can do at any time and wouldn’t have it any other way. I remember when I was in my 20’s, I lived on Lake Winnipesaukee and would run every morning down railroad tracks, having to pay attention to the rails so not to trip – and then getting back and running immediately to the end of the dock and jumping in the lake. You’re so right – the sensation of jumping in cold water and getting your head under is exhilarating. I miss those days! Nowadays I walk fast, not so much jogging and no lake to jump into immediately but thanks for bringing back that great time in my life.

    1. I live in the Midwest, so no chance to jump in the ocean, at least not very often. But I have been forcing myself lately to endure a blast of cold water at the end of my morning shower. It’s a shock to the system, to be sure, but I’m convinced that it is good for me, so I plan to continue doing it.

  7. On ocean plunges.

    My family had a cabin on Lake Superior in N Minnesota. We have always taken family vacations there during the summer. one of our traditions is a swim or plunge in the lake. Now when I do it at in my late 40’s, I can only handle 2 quick plunges and I’m really spent. Feels like I have had an intense exercise session.

  8. Regarding ocean swims, been there and done that years ago when I lived on the gulf coast of Florida. It was fun but I don’t miss it. I much prefer living in Colorado. No oceans, of course, but it can get pretty cold here in the wintertime if that’s what a person likes.

  9. Ok this is going to sound kinda nuts but does anyone worry about having a heart attack if they plunge into cold water?

    1. Not nuts at all. I think it’s a definite consideration for anyone who is over 55 or 60.

      1. It depends on the state of your cardiac health, not necessarily age. I’m 66, and my cardiovascular health is fine (based on all my blood work and other indicators), so I would have no fear at all of doing that. I think someone in their 40s, with poor cardiac/metabolic health, would probably have a much higher risk than I have.

    2. I think if you’re in good general cardiac health, moving a lot at a slow pace, strength training (with some brief, intense sessions), and occasionally sprinting, then a cold water plunge isn’t going to present you with any issues.

  10. About the cold water swims. 1969 BUD training off of Coronado. 4 mile open water swim with 4-6 foot swells. Some went into shock while swimming. Very invigorating!

  11. I enjoy river swimming and have found that I can swim for longer now that I’m full carnivore. I think the increase in protein helps me to stay warm. I drink bone broth (full of electrolytes) and can handle the cold even better… I think it’s the potassium. I’ve also read that exposing the body to hot and cold temperatures produces glutathione. It’s got to be good 🙂

  12. My foray into cold water exposure is simple. At the end of a shower I adjust the water colder, little by little until I can’t take it anymore. This is nice especially before bed as it helps lower my core temperature a few degrees which is conducive for quality sleep ( see Matthew Walker “Why We Sleep” an excellent book on that subject ).

  13. In northern Montana its only river plunges. The river on our property never gets above 55 degrees. We have an annual winter solstice polar plunge. For some crazy reason we have never had the same people join us a second year. The water is usually 33-35 degrees. Very invigorating.

  14. I’m a morning person in summer. I wake with the sun, which is awfully early in this latitude at this season. But in winter I tend to sleep in more, so I try to keep up the habit of getting up early and turning on the full spectrum light to study for half an hour before starting the day. So I suppose I’m neither a morning nor a night person, just a daylight person.

  15. I’ve been cold showering for over 10 years now and without a doubt it has made me more resistant to cold water. I swam easily, early in the morning at 7,000 feet in Glacier National Park in late August with snowfields just above me and in a northern Maine pond on a mid-September morning when the air temperature was 40.

    Cold water exposure is an energy booster for me.

  16. When I was a kid, we used to go to Brighton Beach located in Brooklyn, NY. My brothers and sisters were always too scared of the water, but me, I would run right into it and engulf myself completely in the cold, cold water on early summer days. Yes, Brighton Beach is very cold early in the mornings even in the summer. I used to dive right in and almost immediately my body would get accustomed to the cold. Just like you said, if you wet your head first and take it under water, the body would follow suit. Thanks for bringing back wonderful memories, Mark.

  17. A Maine guy didn’t like cold water?! ??
    Fellow New Englander here (North Shore, above Boston… Ipswich)….been loving my cold plunges at Crane’s beach. One summer, I plunged every day while on a 5 day fast. Felt amazing, lost 20 lbs in a week. Good stuff!

    1. That’s what I thought when I read Mark’s rant about cold water.

  18. I am surprised on the inclusion of an article published by Swiss Policy Research, an anonymous, WordPress blog. I realize that the conclusions of this particular article may be attractive to the message from MDA, but Swiss Policy Research is getting a reputation for pushing conspiracy theories and pseudoscience. A quick read of many of their posts indicates bias and presentation of questionable “facts.”

  19. I’ve been jumping in the Puget Sound nearly 3 times a week in Seattle lately, even during the winter. Now during the summer months the water is no longer cold enough to give me an ice cream headache. I often end the swim session with some jump-rope and maybe a handstand pushup or two. I usually leave the beach with more energy than I brought there.
