I posted this in general health but didn't get any replies so trying here.
Does any one else suffer from fuzzy head (like when you have a cold/ flu) the day after exercise. I've been having it for at least the last three years. I noticed it during lock down (previously always thought I was fighting a virus) and only really started running again the year before. Exercise is only 30 min run or ten minute strength training so not talking over training. Not had covid before it started (and very negative antibody test in 2021).
I've tried electrolyte powder after exercise (doesn't help although a few salt crystals seemed to so maybe not enough sodium in the powder?). Also wondering if it could be insufficient carbs before/ after exercise (trying to loose some weight and prevent blood sugar spikes so don't eat much after the exercise). The strength training is after tea in the evening.
Mid forties so could it be perimenopause? Post exertional malaise/ chronic fatigue syndrome? No other symptoms of cfs.
