Frequently Asked Questions
What causes brain fog?
Brain fog is not a medical diagnosis but a symptom cluster associated with sleep deprivation, stress, anxiety, post-viral illness (including Long COVID), hypothyroidism, nutritional deficiencies, and ADHD. Persistent brain fog warrants a GP consultation.
How much sleep do adults need?
Adults need 7–9 hours per night for optimal cognitive function. Chronic sleep restriction below 6 hours is associated with impaired memory consolidation, slower reaction times, and increased anxiety and depression risk.
