In the world of health and fitness there are a ton of varying ideas out there. Just look at diet for instance. At the same time some are arguing you should eat zero animal products others are arguing for the carnivore diet. In the end, though, you are the only person that matters. I know that’s what you’ve always wanted to hear anyways!
Of course, there are facts about what is healthy and what is not, but ultimately it comes down to what works for you. The practices you use for having the best sleep or maintaining a healthy weight need to be the ones that work for you. In the health industry we make generalizations that we believe will help the largest percentage of people, but you have to try different routines and see what works for yourself.
The hardest part about you being the only subject in your study is that you have to learn to listen to yourself. The experiment never works if we simply convince ourselves of false outcomes. I’ve heard too many times comments like “I just function better on 4 hours of sleep instead of 8.” Well….I would be very skeptical of that and more inclined to think you haven’t done a proper study on yourself. You would need to actually measure your productivity on 4 hours and then on 8 hours of sleep.
Whether it is diet, sleep, exercise, or breathing I encourage you to tune in to yourself. Be honest about what works and what doesn’t for you. What are the current variables in your life you can adjust one at a time to see if you feel better and happier?
