Apart from causing headaches, dehydration may also impede the function of the brain, so it will negatively affect your mood, memory and decision- making skills.
A study published in 2013 in Clinical Autonomic Research showed that the lack of water in the body is one of the major reasons for brain fog along with a lack of sleep, fatigue, and prolonged standing.
Another research published in the British Journal of Nutrition in 2011 proved that it can also cause mood swings.
In most cases, when the body is water deficient, it causes signs of brain fog, which include difficulties in communicating, thinking and focusing, as well as forgetfulness.
