Brain Function
Dehydration can alter brain function and contribute to synthesizing neurotransmitters and hormones. As a result, long-term dehydration can cause issues with thoughts and reasoning. Furthermore, lack of water in the body impacts the neurological system, affecting mood and cognitive abilities.
Drinking water can enhance mood and the activity of the central nervous system, according to 2019 research. The study demonstrated that participants’ self-reported anxiety levels decreased. Their brain activity increased during mentally challenging activities after drinking water.
Water also facilitates communication between brain cells, removes waste and poisons that harm cognitive function, and transports nutrients to the brain. Conversely, everything collapses if the fluid levels decrease.
Cortisol, a stress hormone, is also produced at high levels when a person is dehydrated. Chronic stress and elevated cortisol levels can cause psychological issues, including social withdrawal and isolation.
Brain functions start to deteriorate when fluid intake drops. This explains the strong link between dehydration and poor brain health. Experts advise drinking more fluids to support and improve cognition in various ways, including learning and focus.
