Lack of sleep: Poor sleep may affect the quality of human brain functions, according to research conducted in 2021, so it is usually recommended to sleep daily for a period of between 8 and 9 hours. Hormonal changes: 2018 research found that hormonal changes can also cause brain fog. For example, progestero ne and estrogen levels rise during pregnancy, leading to some effect on short-term memory. Diet: Diet can also play a role in brain fog.
