Patients with hypertension sometimes show insomnia and poor sleep, but it is not directly related to hypertension itself, but more closely related to the concomitant symptoms of hypertension. Patients with hypertension and other patients face many social problems, family problems, economic problems, and work pressure problems, and often these are more important causes of sleep disorders. For hypertension itself, some secondary hypertension may cause sleep disorders, for example, patients with hypertension due to hyperthyroidism are prone to sleep disorders; hypertension combined with cerebrovascular lesions lead to poor sleep, therefore, the main cause of sleep disorders due to hypertension is comorbidity. Statistics show that patients with nocturnal sleep apnea sleep with sleep disorders look good but actually have poorer quality. In addition, some hypertensive patients have poor kidney function leading to polyuria at night, which also leads to poor sleep, so there is no direct relationship between the degree of hypertension and poor sleep.
