Perhaps this particular entry has a dual focus. Partly discussing how amazing the human body actually is, and also discussing the need for it to be challenged and how to do just that.
As I was contemplating human biology, anatomy, and physiology (yes sometimes I actually do marvel at those things), I have the feeling and my experiences have lead me to understand that my body needs to be challenged in many different ways to achieve high and lasting levels of health.
To further elaborate the point I will give you a few examples that I have either seen or experienced personally and hope will be of some use.
Cold showers. I know, I know, where am I going with cold showers, right?
I learned the joy (and fear) of cold showers many years ago as an LDS missionary in the Dominican Republic. Logic would have it that showering with cool water in an otherwise hot and muggy environment would be pleasurable.
But no, at least for me, no cold shower is initially enjoyable; it is just shocking to the system. However, after the initial shock has worn off, it is wonderfully refreshing.
Upon returning to the US I remember the joys of again experiencing a hot shower. Yes, hot showers are great too, don’t get me wrong.
Years later I decided to incorporate cold showers into my daily routine. But how would I do this, as I love hot showers so much? Here was my compromise:
Beginning and middle of the shower is hot (well, comfortably hot). The last 2-3 minutes I put it on the coldest setting.
The initial jolt is not pleasant at all (especially when you are first getting accustomed to cold showers), but it’s not so bad after the first 10-20 seconds and ends up being wonderfully refreshing.
It is well documented that athletes, particularly professional football players will lay in tubs of ice water to speed up their recovery times between weekly games. Due to the high impact nature of the game, many players insist this is necessary for recovery by the following Sunday’s game.
I’m no football player (foosball yes), but I do feel better both physically and mentally when I have my cold showers.
Why is something that is initially unpleasant so good for my body? I believe it’s because the body is contrarian and has robust responses to virtually any challenge it encounters.
Another slightly masochistic way I have found additional health and mental/spiritual benefits is through fasting.
Members of the Church of Jesus Christ of Latter-Day Saints (of which I am) and many other religions practice fasting in some form or another. In my church, we are encouraged (if able) to attempt to go 24 hours without food or water the first Sunday of each month. While I will discuss specifics about the physical benefits, there are some amazing spiritual and psychological benefits to fasting too.
Just the ability to abstain from something as basic and necessary as food and water instills the ability to abstain from vices and other short-term desires than draw dire long-term consequences.
But physically, regarding the human body, fasting initially seems like a bad idea. Certainly it’s an uncomfortable one and while it is uncomfortable, through that discomfort many health benefits are achieved. Improved insulin resistance, for example:
After diminishing it’s glycogen stores, the body is forced into a ketogenic state where it must then convert body fat to replenish the lost energy stores. Additionally, the body releases multiples of it’s normal levels of human-growth hormone, which assists with a number of physiological processes. The digestive system gets a bit of a break and can rebalance it’s functions.
I feel better after I fast, even if I don’t feel great when I am fasting.
The body needs to be challenged. A body in a state of consistent stasis begins to experience various maladies.
That brings me to fitness. A few years ago, after reading a number of articles about the benefits of HIIT (High Intensity Interval Training) I decided to incorporate it into my regular exercise routine (I mostly follow a body-building regime via weightlifting and cardio exercise).
The HIIT sessions are by-far my most difficult and intense workouts. While I do somewhat dread the workout, I also look forward to them the most, because it is truly both physically and mentally challenging and produces an amazing mind altering effect.
This is the feeling about 30 minutes to 2 hours after doing HIIT, and it is like a drug (not that I know, haha), the endorphins and whatever other chemicals and hormones the body begins to produce/release to help me recover from the intense exercise are wonderful!
I honestly feel like I’m on top of the world both mentally and physically. I also feel great after my normal workouts, but the HIIT does something above and beyond. I’m sure this is similar to what runners refer to as “runners high”.
Now, regarding germs: I know that people who are in overly sterilized and filtered environments often have weakened immune systems and struggle with allergies, especially babies that have little exposure early on.
Human impulse is to sanitize everything. While I believe it is good to be clean, and there is no need to unnecessarily expose oneself to something harmful, I try not to be too extreme with sanitization and also ensure that I am getting at least a healthy share of probiotics (good bacteria).
Interestingly enough, a good mix of natural probiotic foods have a balance of about 85/15 good/bad bacteria. I thought that was fascinating, why would it have any bad bacteria?!?
Our bodies are designed to overcome problems, sickness, to rebuild and then fortify broken-down muscles, to revitalize and make more efficient our cardiovascular system when it is stressed by exercise.
The opposite, indulgence, all to often creates hazard, weakness, and sickness. High consumption of sugar for example:
The body craves it, loves it, but doesn’t need it.
Being sedentary also has it’s pitfalls. Sometimes it feels great to relax, especially when you’ve earned it. But if relaxing is all you do, your body quickly begins to have a number of health issues.
We’re often told to “stay out of the sun” or make sure you have sunscreen on when you are outside. But guess what? The most efficient way to produce Vitamin D is from sunlight! Not only that, but being in the sun has a verifiably positive effect on mood.
I get it, too much of anything can ultimately be bad. But our bodies are designed to resist and regenerate. The human body desires to be challenged, and often thrives in the face of challenge.
I’ve tried to stop babying myself.
I get it. It’s a balancing act. Eating healthy most of the time, but having a “cheat meal” some of the time, then occasionally no food at all. Work out regularly (pushing yourself hard on occasions), and enjoy some rest days in between. Get some sun, just not too much.
And yes, enjoy the hot shower, then hit me with the cold!
