There is a statistic that people who have nocturia (frequent urination at night) have a lower survival rate than people who don’t. Also When waking up at night and going to the bathroom, there are people who sometimes fall down and break a bone, lowering the quality of life.
The main cause of nocturiais too much intake of water at night such as water, tea, coffee or alcohols.
Another cause that you have to pay attention to is swollen legs.
While spending daytime, blood tends to be accumulated in the legs by the influence of gravity. In addition to that, aging causes the power to push out the blood from the heart and the power to return the blood from the legs to the heart weaker, resulting in that water comes out from the blood accumulated in the legs. This is the cause of swollen legs.
Why do swollen legs become a cause of nocturia?
While sleeping at night, the level of the legs is equal to the heart’s, so blood containing a lot of water comes back to the heart easily without the influence of the gravity. There is a sensor in the right atrium, which detects the amount of water. The sensor orders the kidney to make more urine from the blood to prevent the heart from having too much water. To improve this type of nocturia, it is important to improve swollen legs.
How to improve noctruia caused by swollen legs
(1) Massage your legs from the ankle to the knee (Fig.1).
(2) Walk in the evening.
Moving the muscles in the calves promotes the dilation and contraction of the blood vessels, pumping the blood back to the heart. Walking in the evening makes urine before going to bed.
