As someone who went for a long time before having my sleep issues officially diagnosed I'd recommend taking care of the why you are sleeping deprived first. While doing something quick to keep your mind sharp is fine it's not going to help with the drowsiness overall.

Yes, I do sometimes pace around while reading something too (the most boring are terms and conditions for new contracts). But that's because now my mind tends to wander when the literature or document isn't very engaging and not due to drowsiness anymore. Once I got my sleep issues sorted out which caused perpetual lack of sleep due to it before. It's better for your overall health to cut out a little training to get the right amount of sleep for your body.

Fellows,

at work I need to read a lot. Like scientific literature. Sitting on my butt for a long time plus lack of sleep plus fatigue from training makes me quite sleepy and I lose track of the stuff that I am reading.

Lately, I have fought off sleep by getting up and walking around for a few steps. It helped me to bring my circulation back on track and actually works quite well. Now, I am thinking about to go even one step further and incorporate some strength training.

What do slowtwitch people think? Am I crazy? Are you guys doing it as well? How should I spend a 5 min break?

Just thinking out loud: 15 min of strength training per day 5 days a week would make 1h15 of strength training. That's an hour of "free training" - am I wrong?

Thanks for sharing your thoughts.
Uli

PS: I could do all my exercises in private. No need to expose myself as the office weirdo - not that I heaven't already done that by being me ;-)
