However, it is necessary to clearly understand the real mechanism to avoid misunderstanding that warm water has the ability to detoxify directly. In fact, the liver and kidneys are two organs that automatically perform the function of filtering and eliminating toxins. This process takes place continuously, not completely dependent on the time of drinking water.
However, staying hydrated, including drinking warm water before bed, still has indirect benefits that help these two organs function more effectively.
Warm water helps increase blood circulation, supports metabolism and keeps the body in a state of balance. When the body is hydrated, the kidneys have better blood filtration conditions, reduce the risk of kidney stones and support the excretion of waste products through urine.
For the liver, adequate hydration helps optimize fat metabolism, breakdown and maintain night-time performance - the time when many visceral recovery processes take place.
Drinking warm water in the evening helps relax the nervous system, supporting deeper sleep. Quality sleep plays an important role in liver health. Because while sleeping, the liver performs many activities of cell regeneration and blood filtration. Intermittent sleep or prolonged lack of sleep can negatively affect liver function and metabolism.
However, drinking too much water right before bed can cause drowsiness, disrupt sleep, thereby affecting liver and kidney health. A reasonable amount of water is usually about 150250 ml, depending on the body's needs. The water should be slightly warm, not too hot to avoid mucosal irritation.
More importantly, supporting healthy liver and kidneys requires combining many factors such as a diet low in saturated fat, limiting alcohol, maintaining a reasonable weight, exercising regularly and drinking enough water throughout the day, not just before bed.
Drinking warm water before bed does not directly detoxify but contributes to improving circulation, supporting sleep and maintaining a favorable environment for liver and kidneys to function effectively. This is a good habit if done properly and combined with a healthy lifestyle.
