Are you troubled by Brain Fog? Wish you could counter it but don't know what to do? Too 'foggy' and tired really even to try to think about what to do? Well I offer some simple suggestions.
First off I'd recommend cutting down on salt and salty food. People who try this are commonly amazed at how much better they feel, and how much brighter, happier and more energetic. Even in just a few days.
Secondly, cut down on sugar and sugary food, and on bread/biscuits/wheat. These are notorious for causing fluctuations in blood sugar levels, which can lead on type 2 diabetes, with its attendant health problems of overweight, tiredness, vision damage/possible blindness, cognitive decline, impaired mobility, depression and many more, including premature death.
Improve your nutrition. - You're tired and you can't think straight and that makes processed ready meals/convenience foods a big temptation. Try hard to overcome this temptation because this sort of food is usually high in salt and sugar, the baddies I have already indicted, and very low in nutrients that your brain and body need. They are nutrient-poor and baddie-rich. Instead of taste, they offer addictive saltiness and sweetness, with the added harm of artificial colours, artificial toxic garbage like MSG (monosodium glutamate), synthetic transfats to lengthen 'shelf life', etc. (Note: if an ingredient lengthens the shelf life of a food product, it's a pound to a penny that it shortens the longevity of the person who eats the product!)
Vitamins that are especially helpful for brain fog are Vitamin B12 and Vitamin D. - If you click on the Vitamin D label beneath this blogpost you can read some of my earlier blogposts that go into more detail about this very important vitamin. See also this related page with more info about Vitamin D and other essential nutrients.) Similarly you can read further about Vitamin B12 by clicking on its label beneath this post.
Avoid taking anti-depressants, the ultimate in pharmaceutical junk! Tricyclics and any other drugs that have anticholinergic properties cause memory loss, cognitive impairment/decline and can lead eventually to dementia. You've only got one brain and one body. Don't damage them with pharmaceutical junk.
As you gradually improve your health in the ways - or at least some of the ways - I have mentioned - you will hopefully soon have the energy to do a bit more and take a bit more exercise than you can manage at present. Exercise will in turn add to the virtuous circle and reduce your brain fog and ill-health even further.
And here's a more authoritative and much more detailed webpage about clearing brain fog for when you can cope with reading more demanding reading material than my little effort.
