Furthermore, when sleep is interrupted several times, the body does not properly enter its deep rest phases. This can affect energy, mood, and even blood pressure. Lack of continuous sleep is not only tiring: it also alters how the body regulates fluids and salts.
Some signs that usually accompany this problem are:
-
Darker urine than usual in the morning.
-
Swollen ankles or feet upon waking.
-
Intense feeling of thirst in the afternoon or evening.
-
Frequent awakenings without feeling rested.
-
Urine with a stronger odor than normal.
If these discomforts appear often, do not ignore them. The Cleveland Clinic and other medical institutions note that nocturnal urinary frequency can be related to hydration, age, medications, salt intake, and some health issues worth checking out.
