I recently had an experience where I needed to do physical labor about 16 hours a day for two weeks, at the same time there was hardly any time to eat so I had to eat very small and simple meals. At the end of the two weeks I felt amazing.

Be careful with that feeling and don't underfuel, or at least keep it at "sane" levels. I feel pretty amazing and full after 62km/2700mD+ XCMs as well, as an extreme example... which is at least partially due to the immune system (and resp. inflammation/etc) being suppressed. Long, light/moderate efforts without adequate food intake and rest can lead to the same thing.

What are XCMs? 2700mD? Why would the immune system being suppressed make you feel good? I’m so confused

		Stress hormones. Read up on cortisol's effects. XCM - cross country marathon (MTB race). 2700mD+ - 2.7km of vertical gain. A reduction of inflammation is a general effect of anti-inflammatory drugs, which tend to make you feel better. There's a LOT more than that (i.e. say, all the things that fall under the umbrella of "runner's high"), but the TL:DR is that significant physical activity / energy expenditure, combined with a lack of proper rest & nutrition leads to long-term undesirable effects that can definitely be masked and/or disregarded.

I fugure XCM must be cross country marathon, where 62km is the distance. But what is mD? Difference in elevation in meters?

I have no idea what you wrote and you shouldn't assume people know some niece jargon.

Did a major house cleaning a few years ago, got me out of the chair and the couch for a couple of weeks. Probably not as intense as your experience but I definitely felt better and was more flexible for about a month afterwards.

I think this works well for relatively short bursts, but if you made it a regular habit your body would start to break down after a year or two.
