The blood pressure drop is essential to relieve the heart of some stress and establish normal breathing. Poor sleep which might be due to sudden disruption or disorders is likely to keep your blood pressure high even during the night. Studies have shown that high nocturnal blood pressure is a bigger contributor to hypertension than high day blood pressure.

Lack of sleep associated with heart failure, arrhythmia

On the occasion of World Heart Day which is observed on September 29 every year, Dr Sibasish Dey, Head of Medical Affairs, South Asia, ResMed explains the relation between sleep and cardiac health. He says: "Several key physiological phenomena occur while one is asleep. This can be maintaining primary homeostatic functions, restoring energy, repairing tissues, allowing the brain to consolidate and process information, immune regulation and so on. Sleep helps in regulating the hormonal balance in our body including various stress hormones. Given today's long work hours and late nights, if one is not sleeping adequately for an extended period, the body's ability to manage stress may be adversely impacted and consequently may lead to cardiac complications in long run. Clinical research over the years has shown an association between sleep deprivation with heart failure, arrhythmia and high blood pressure. Therefore, it is imperative to get a good sleep both in terms of quality and quantity. Daily exercise, weight loss, moderation of caffeine, smoking and alcohol are some of the ways to have restful sleep and keep the heart healthy".
