Keeping active plays a huge rôle in tiredness, sleep and much more. I think the last few years with Covid have been very hard on all of us. And I also have had 2 major operations.
I have returned to a more active life, started doing Gi-Gung, swimming, walking, cycling, again, lost some weight (still chubby but fit with it), and going out more, and I now feel better than I have for a long time. I know it is hard for some to be physically active, for all sorts of reasons- but honestly, try to get back to some physical activity, slowly but surely. I am sure it really helps, mentally and emotionally too.
