Why do I get severe brain fog after a couple days of heavy weightlifting?

After intense weightlifting sessions, some individuals experience severe brain fog, characterized by difficulty concentrating, fatigue, and impaired cognitive function. Here are some potential reasons:

  • Hormonal imbalances: Weightlifting can cause a surge in certain hormones, such as cortisol, which in excess can disrupt sleep, metabolism, and cognitive functioning.
  • Neurochemical changes: Exercise-induced inflammation and oxidative stress can affect brain chemistry, leading to decreased production of neurotransmitters like serotonin, which can impair mood, sleep, and cognitive performance.
  • Dehydration: Weightlifting can cause significant fluid loss, leading to dehydration. Dehydration can reduce blood flow to the brain, impairing cognitive function.
  • Nutrient deficiencies: Weightlifting requires a high demand for nutrients, and a lack thereof can contribute to brain fog. Specifically, vitamin B12 deficiency is linked to impaired cognitive function.
  • Sleep deprivation: Intense weightlifting can disrupt sleep patterns, leading to sleep deprivation and subsequent cognitive impairment.
