Dehydration triggers stress alarm in the brain

A new study from the UK has found that people who don't drink enough water experience more stress. Researchers have found that those who regularly drink less water have an exaggerated biological response to stress.

According to the study, those who don't drink enough water produce higher levels of the stress hormone cortisol. Experts say that keeping a water bottle with you during stressful times or during an important conversation can be beneficial for both immediate and long-term health.

“WATER LACK AFFECTS MENTAL HEALTH”

Child and Adolescent Psychiatrist Dr. Günay Budagova, who evaluated the research, said that water consumption should be increased in extremely hot weather, during the recovery period from illness, and during pregnancy.

Budagova stated that men should consume 2.5 liters of water a day and women 2 liters, and provided the following information:

"Dehydration doesn't directly cause stress, but it disrupts the body's hormonal balance, affecting mental performance, which in turn increases the stress response. There's a strong connection between dehydration and mental health. Low fluid levels can lead to hormone changes, cognitive impairment, poor sleep, and mood-damaging symptoms. Even mild dehydration can increase cortisol levels and reduce the production of the happiness hormone. This can make people feel irritable, sad, and exhausted."

It weakens attention and decision making

Dr. Budagova emphasized that dehydration also disrupts electrolyte balance, which has negative effects on cognitive functions:

"Electrolytes regulate cognitive processes such as attention, learning, decision-making, and memory. When they are out of balance, these functions are impaired. An excessive cortisol response to stress can increase the risk of heart disease, diabetes, and depression."
