Adequate sleep and exercise are two good ways to improve lymphatic drainage.

Exercise, it's always exercise.

Exercise and sleep*

Why can't they put the effects of exercise and sleep into a pill, patch, or suppository? In all seriousness that'd be pretty great.

Id just take the sleeping pill, i like to exercise and wouldn't want to lose that, but really don't like sleeping.

How does doing exercise not make you tired? When I do a workout I can’t fight the exhaustion when 9pm hits and I’m in bed and sleep like a rock until the sun comes out.

Could be the difference between those that get a "runner's high" from exercise vs those that don't. If I'm going to have to stay awake for longer than normal (adjusting for swing shifts), I plan for my exercise to take place before the last 6-8 hours of that because it gives me such a mental and physical energy boost.

Doesn’t everyone get a runner’s high if you run long enough? It just takes 20+ mins of running and most people can’t do that.

I honestly think some people don't, maybe it's a genetic thing, maybe it's a learned thing, but some are adamant that exercise them discomfort.

And it would really suck for that to be your experience. I couldn't imagine exercising without that rush on endorphins and confidence. It's gotten to the point where my energy levels paradoxically tank on the days I don't exercise. If I'm working a long shift I feel twice as alert throughout the day when I've exercised before

There's a high correlation between not receiving the endorphin rush from running and having ADHD. I never believed that high was real until I tried exercising on stimulants.

Back when I was actively exercising regularly there was not a single time where I felt anything but exhaustion and aches. I was just going through it all with the mantra of ‘Do this to be healthy.’ running through my mind constantly and that was NOT encouraging at all. A big factor of why I stopped. It became a greater drain on me than any benefits I was observing (which was probably a purely psychological thing, as there were probably great benefits, but that is just how a mind works).
