Failing to Drink Enough Water Impacts Brain, Increases Risk of Accidents


August 02, 2018

USA- Thejakartapost.com reports that a study released in July 2018 shows that dehydration has a significant impact on human cognitive function. The dehydration a person could experience in a couple ofhours of activity on a hot summer day is enough to impair a person’s ability to concentrate.*

The study was conductedat the Georgia Institute of Technology, and it looked into the ways in which acute dehydration, which can be experienced from exposure to heat, after exerting energy, or after not drinking, can impact cognition. The levels of dehydration studied could be experienced by anyone under fairly common circumstances. 

The functions impacted most severely include “attention, coordination and complex problem-solving.” 

Repetitive, boring tasks were impactedthe most. This includes activities such as pushing a button. Activities that require reactions are lessimpactedbut still demonstrated diminished functionality.  

Examples of tasks that a person who is dehydrated might struggle to perform include keeping their focus in a long meeting, staying alert in a factory job, and driving a car. 

People also indicated a decreased ability to do mathand complete other higher-order functions.

The researchers concluded that people who are dehydrated could be at a greater risk of being involved in an accident. People using heavy machinery in hot environments could be at particularly high risk of being dehydration related accidents. 

One of the researchers pointed out that while dehydration is a major problem, it is also possible to drink too much water. Drinking too much water dilutes a person’s blood and can lead to swelling of the brain. This can even lead to death in extreme cases.
