Dehydration has been a subject of concern among health experts for a long time. A shortage of water in the body can lead to many adverse effects, including cognitive function impairment.

In recent studies, dehydration showed various cognitive symptoms in both young and elderly individuals.

The Impact of Dehydration on Cognitive Function

Dehydration can significantly impact cognitive function, resulting in various mental impairments. Below are some of the most common symptoms related to dehydration:.

Decreased Attention

One of the early symptoms of dehydration is a decrease in attention and concentration. It is common to experience lapses in focus when the body is dehydrated, resulting in slower cognitive functions.

Memory Issues

Water is essential for the brain’s overall functioning, particularly regarding memory. Chronic dehydration can lead to impairments in both short-term and long-term memory, causing difficulties with recall and learning.

Mood Disorders

Dehydration contributes to mood disturbances such as anxiety and irritability. It impacts the hormones released by the brain, which affects mental health.

Reduced Brain Performance

Water is responsible for maintaining the inner atmospheres of cells in the body, including brain cells.

The brain’s ability to function is highly dependent on its cells’ hydration level, which can slow down and impair the brain cells’ functioning if depleted; resulting in a decrease in brain performance.

Dehydration and Aging

Older adults are more susceptible to dehydration since the thirst mechanism decreases as a person ages. Besides, advanced years also lead to the kidney’s decreased ability to hold water.

The effects of dehydration, among older people, will cause more significant impairments in cognitive functioning than younger individuals.

Prevention of Dehydration

The good news is that dehydration can be prevented in most situations, and maintaining proper fluid intake throughout the day is one of the most effective solutions. Here are some tips to prevent dehydration:.

Drink water regularly, aiming for at least eight glasses per day.
Consume foods with high water content, including fruits like watermelon.
Avoid alcohol, caffeine, and sugary drinks that can act as diuretics.
Consume fluids before, during, and after physical exercise.
Ensure proper hydration in hot and humid weather.
Monitor fluid levels for elderly people with frequent medical check-ups.

Conclusion

Dehydration shouldn’t be taken lightly. The body needs water to function, and cognitive performance is one of the most critical functions affected by dehydration.

If a person experiences symptoms related to dehydration, he/she can take steps to remedy the situation by consuming enough fluids daily and staying hydrated.
