A new study found that hydration is important when it comes to managing stress.
People who drink 7 cups or 1.5 liters of water per day, or those with less than 1.5 liters, have a cortisol response to stress 50% higher than those who meet water intake recommendations.
Researchers at Liverpool John Moore University (LJMU) have published a study in the Journal of Applied Physiology.
According to scientists, wearable hydration monitors can help prevent heat strokes
Of the 62 healthy men and women, 32 participants were selected for both habitual hypofluid intake and habitual high fluid intake.
Typically subjects I drank it Although 1.5 liters or more of liquid per day was considered the “low fluid” group, the “high fluid” group consisted of people who drank the recommended amount of 2 liters for women and 2.5 liters for men.
Participants’ fluid intake was monitored over a 7-day period by testing Trier’s Social Stress Test (TSST) and hydration markers containing blood and urine.
This study also discovered drinking Small water An increase in stress-related health problems in both men and women.
Professor Neil Walsh, research leader at LJMU’s School of Sports and Exercise Science, said in a press release that keeping your water bottle close to during stress-related times can potentially benefit your long-term health.
“Cortisol is the body’s major stress hormone, and exaggerated cortisol reactivity to stress is associated with an increased risk of heart disease, diabetes Depression” said Walsh.
“Both groups experienced similar anxiety and similar increases in heart rate,” Dr. Daniel Kasi, a member of the research team, said in the release. Stress Test. ”
He added: “Only the ‘low fluid’ group showed a significant increase in salivary cortisol in response to stress tests.”
“The low-fluid population did not report being thirsty than the high-fluid population, but they had darker, concentrated urine, making clear signs of poor hydration,” Kashi said.
“A significant observation was that poor hydration was associated with greater cortisol reactivity to stress tests. Long-term healthKashi added.

Long-term dehydration can lead to more serious health issues, such as kidney damage and failure, anxiety and depression, and heart problems. and diabetesaccording to the Cleveland Clinic.
Dehydration causes the release of vasopressin hormone, which puts pressure on the kidneys, making it difficult to concentrate urine and manage the balance of the electrolyte.
“Vasopressin also affects the brain’s stress response cents[er]According to the LJMU release, “it will affect where the release of cortisol is.”
The release states, “This dual role.” [of] Vasopressin helps maintain a balance between blood volume and electrolytes, but it also increases cortisol. ”
Researchers found that water intake recommendations should be followed, but found that additional research and more longitudinal studies are needed.

Researchers suggest that monitoring the colour of the urine is a good way for people to check their hydration status.
Bright yellow urine color usually indicates good hydration.
“Hydration may help your body manage stress more effectively,” he said.
