Experts have long told us that drinking water is essential for staying healthy. It keeps our joints lubricated, improves blood flow, boosts energy, protects the kidneys, and keeps our skin looking fresh and healthy. Water also regulates body temperature, aids digestion, prevents constipation, lifts our mood, and sharpens the mind. In short, staying hydrated is crucial.
Now, scientists say keeping your body properly hydrated may be even more important than previously thought. Researchers at Liverpool John Moores University in the UK have found that people who don’t drink enough water are more likely to experience mental stress and release higher levels of the hormone cortisol even if they don’t feel as thirsty as those who drink more water.
The study observed 16 people who consumed less than 1.5 liters of water per day and compared them with 16 individuals who followed the European Food Safety Authority (EFSA) recommendations 2.5 liters per day for men and 2 liters per day for women.
According to the UK Eatwell Guide, adults should drink six to eight cups of fluids daily, roughly 1.5 to 2 liters. People may need more in hot weather, if they are very active, recovering from illness, pregnant, or breastfeeding.
During the study, researchers collected urine and blood samples from both groups after seven days. Participants were then brought into the lab for mental stress tests. Various assessments revealed clear differences between the two groups.
Professor Neil Wash of Liverpool John Moores University said the findings showed that those drinking below the recommended daily amount experienced significant mental stress and other issues caused by dehydration. He emphasized that not getting enough water can lead to multiple health problems.
