People who drink less water are more irritable than others.

People who do not drink enough water each day have a stronger biological response to stress, with significantly higher levels of stress hormones than people who drink enough water.

Adults should drink enough 1.5 - 2 liters of water per day.

A new study shows that people who do not drink enough water every day have a stronger biological response to stress, with levels of the hormone cortisol - a hormone associated with stress - much higher than people who drink enough water.

Interestingly, this group did not feel more thirsty, but their bodies responded more negatively to stress.

The study was conducted by experts at Liverpool John Moores University (UK) on 32 adults, of whom 16 drank less than 1.5 liters of water per day and 16 met the recommended water intake.

The study results have reinforced advice from health authorities. Specifically, the European Food Safety Authority (EFSA) recommends that men should drink 2.5 liters of water per day, while women drink 2 liters. Meanwhile, the UK's Healthy Eating Recommendation (Eatwell) also suggests that adults should drink 6-8 glasses of water per day, equivalent to 1.5-2 liters.

Experts emphasize that the need to drink water can increase when it is hot, the body is active, sick or during pregnancy and breastfeeding.

According to the research team, keeping a bottle of water next to you during stressful times not only helps you feel more comfortable mentally but also benefits your long-term health.
