Reasonable water distribution during the day
The body still needs to be hydrated in the evening, but instead of drinking a lot at the same time before going to bed, you should supplement water regularly throughout the day and gradually reduce it at the end of the day. This helps the kidneys not overwork at night, while limiting waking up.
Limit drinking too much water right before bed
Although providing enough water is essential, drinking too much water close to bedtime (above 60-120 ml) can cause you to wake up to urinate in the middle of the night. This disrupts sleep and negatively affects health, including kidney function.
Maintain a regular drinking habit
A healthy kidney system at night largely depends on how you replenish water during the day. Drinking enough and spreading evenly the amount of water helps the body maintain a balanced state, avoiding thirstiness in the evening and having to drink too much before going to bed.
Note watery foods for dinner
Dishes such as soup, soup, or juicy fruits also contribute to the total amount of fluids intake into the body. For people who need to control fluid levels, especially kidney patients, eating a lot of these foods in the evening can put pressure on the kidneys, even leading to edema or high blood pressure.
Avoid caffeinated and sugary drinks
Caffeine has diuretic effects, making you urinate more often and more prone to insomnia, causing the kidneys to work more at night. Meanwhile, sugary drinks can affect blood sugar and harm kidney blood vessels in the long run. Filtered water is still the best choice before bedtime.
Maintain electrolyte balance in the body
Besides water, the body also needs to maintain electrolyte balance. Drinking too much pure water without minerals can reduce blood sodium levels, affecting the kidneys and nervous system, especially in people with underlying diseases.
Notes for people with kidney disease
People with chronic kidney disease or undergoing dialysis need to strictly adhere to the amount of water prescribed by their doctor. Drinking even a small amount before bed can cause edema, shortness of breath or increase pressure on the body.
Monitor urine color for adjustment
Observing urine color is a simple way to assess your body condition. Light yellow urine shows that you have drunk enough water, while dark yellow is a sign that you need to supplement more. This habit helps adjust the amount of water reasonably, avoiding putting pressure on the kidneys.
