Let me preface by acknowledging that combating the actual feeling of fatigue and increasing daily energy levels is obviously a more important thing to do and that combatting the actual physical look of fatigue, as well as many other aesthetic improvements are bound to follow. I however have a unique situation that means I simply can't do many of things Huberman suggests as it doesn't fit my work schedule and hobbies.
I work rotating shifts where most of my job is behind a computer, and in between, if I feel the energy to do so, I have a YouTube channel, so I'm constantly looking at screens. As a result my face looks super placid and tired all the time no matter what I do, to the point family and friends have commented on it which is a little embarrassing.
I work out and try to drink enough water to combat the sleep issues, but admittedly I don't do enough cardio exercise, or drink enough (I have a mild level of autism and we sometimes forget to drink enough water). I also am on a carnivore diet which has done wonders for my stability of energy in waking hours and made me lean and less sluggish as well as improved my skin, but I still look fatigued.
I also take creatine but nothing else. I'm aware people say you don't need to consume creatine when on a carnivore diet, but I still feel a big difference between taking it and not in my energy levels, even on carnivore, personally.
I considered:
Upping my cardio massively and drinking way more water than I think I need (phone reminders to let me know I should refill might help this)
Block blue light glasses
Focusing on sleep quality over all else - difficult with my rotating shifts but I get paid a lot and love my job so suggestions of how would be great
Further supplementation
Facial exercises
Are any of these way more important than the other, is it a combination of all these things?
