The ultimate "tool" for elevated focus for me is napping. A quick 20 min nap completely resets my mind so I don't have whatever random thoughts floating around.

If you are more disciplined than me, meditation in place of napping could work. But napping is easier and more enjoyable to me. As for brain fog itself, I think proper nutrition is very important. Our body needs many different micronutrients to operate at optimal capacity and many peoples' diets don't meet these. Lastly, I don't know how true this is, but a chiropractor told me that poor neck posture can result in reduced blood flow to the brain which can reduce your cognitive capacity (i.e. feeling of brain fog).
