ESPDrinking too little water could increase our vulnerability to stress-related health issues, according to a new study from scientists at LJMU.
People who drink less than the recommended daily fluid intake experience a greater stress hormone response, which is associated with an increased risk of heart disease, diabetes and depression.
A new study, published recently in the Journal of Applied Physiology, found that individuals who drank less than 1.5 liters of fluid – or seven cups of tea – per day had a cortisol response to stress that was over 50% higher than those who met daily water intake recommendations.
Study lead, Professor Neil Walsh, a physiologist in LJMU's School of Sport and Exercise Sciences, said: "Cortisol is the body's primary stress hormone and exaggerated cortisol reactivity to stress is associated with an increased risk of heart disease, diabetes and depression."
"If you know you have a looming deadline or a speech to make, keeping a water bottle close could be a good habit with potential benefits for your long-term health."
