Khaberni - Many people struggle to start their day energetically due to mild dehydration and mental fatigue upon waking.
In this context, Dr. Amir Khan, a primary care physician at the British National Health Service, recommends a simple habit that takes only seconds: drinking a glass of water immediately upon waking.
Khan emphasizes that the body loses fluids during sleep, leading to mild dehydration - even without feeling thirsty - which can affect energy levels, focus, and mood. Therefore, providing the body with water at the beginning of the day helps quickly restore its balance.
The benefits of this morning habit are not limited to hydration only but include several health aspects, such as:
Boosting metabolism and signaling the body to start activity.
Supporting kidney and liver functions in waste removal.
Improving concentration and memory and reducing feelings of mental confusion.
Enhancing the efficiency of the digestive system, especially when consuming a fiber-rich breakfast.
Helping to maintain skin freshness and hydration.
The doctor describes this step as a "small habit" that makes a "big difference," noting that he ensures to have a glass of water next to his bed to drink it immediately upon waking, as a symbolic gesture to start a healthy day.
For its part, the National Health Service does not specify a fixed amount of water to drink daily, but it advises maintaining adequate hydration so that the urine color is light. This usually translates to drinking between 6 to 8 cups of fluids daily, with an increase in quantity in situations like hot weather, physical activity, or pregnancy and breastfeeding.
The authority also affirms that water remains the best choice, with the possibility of consuming other unsweetened drinks such as tea and coffee, while reducing sugars and caffeine.
The importance of this advice lies in the fact that water makes up a large percentage of the human body and plays a crucial role in its vital functions. Studies indicate that even mild dehydration can affect mental performance, whereas drinking water helps improve concentration and decision-making.
