The act of drinking water as a possible mechanism to reduce stress has been a subject of growing interest among researchers and physicians in different regions of the world. In recent years, the link between hydration and the reduction of emotional tension has been analyzed in depth by health specialists, who seek to determine if there is a direct relationship between both factors.
According to a report published by the New York Times, the connection between water consumption and stress management is based on clinical observations and recent studies that have evaluated both the physiological impact and the emotional well-being of patients.
Likewise, several research teams have observed that a lack of water can alter the body’s hormonal balance, which translates into an increase in cortisol levels, the main hormone associated with the stress response.
In the words of Dr. Lisa Mosconi, director of the Nutrition Science Lab at Cornell University, “mild dehydration affects brain function and can make people feel more anxious or irritable.” This statement was reported by the Washington Post, which included Mosconi’s testimony in a report on healthy habits for stress management.
The Washington Post also interviewed Dr. James Huddleston, an internal medicine specialist at Stanford Hospital, who explained that “drinking water regularly helps keep physiological systems in balance, which allows the body to react more efficiently to stressors.” He even highlighted that, although it cannot be considered a sole remedy for stress, it is a key element within a preventive approach and general health care.

Relationship between hydration and physiological stress response
Drinking water has gained interest among researchers and physicians as a potential support for reducing stress.
According to the Washington Post, proper hydration contributes to the optimal functioning of the nervous system, which can influence mood and the body’s ability to handle stressful situations.
Doctors interviewed by this media outlet stressed that, when the body experiences mild dehydration, symptoms such as headaches, fatigue, and irritability can appear, factors that facilitate the onset of stress.

Dr. Lisa Mosconi, director of the Nutrition Neuroscience Laboratory at Cornell University, explained to the Washington Post that “a lack of water causes changes in the concentration of certain stress-related hormones, such as cortisol.” According to the specialist, consuming water regularly helps keep hormone levels within normal parameters, which can translate into greater emotional stability.
The New York Times collected testimonies from patients who noticed a decrease in anxiety after increasing their daily water intake. Although the experts cited by this outlet warn that hydration is not a substitute for other medical treatments for stress management, they agree that drinking enough water promotes general well-being and can be a supporting factor in controlling emotional tension.
Scientific evidence and international recommendations
Lisa Mosconi stated that a lack of water affects brain function and can increase anxiety and irritability.
A report published by the Mayo Clinic in the United States, cited by CNN Health, points out that mild dehydration generates physiological responses that mimic the symptoms of stress. The organization recommends that adults consume at least 2 liters of water daily, adjusting the amount based on physical activity and weather conditions.
In that tone, it details that, in controlled studies, volunteers who maintained constant hydration reported lower levels of anxiety and better concentration compared to those who reduced their fluid intake.
Dr. David S. Goldfarb, a professor of medicine and nephrology specialist at New York University (NYU), stated in comments to CNN Health that “water is not a cure for stress, but there is a positive correlation observed between being hydrated and experiencing fewer symptoms associated with psychological tension.”

For its part, the American Psychological Association (APA) recommends that those facing high-stress situations pay attention to their hydration. The APA considers that water is a simple and accessible resource that supports brain function and helps modulate the emotional response.
Specialists agree that there is no evidence to support the use of water as a sole treatment for stress, but they warn that dehydration can aggravate symptoms and hinder emotional recovery. The general recommendation from experts is to maintain a regular intake of water as part of a comprehensive approach to caring for mental and physical health.
