Sleep plays an important role in regulating blood pressure and supporting cardiovascular health. During deep sleep, blood pressure normally falls, giving the heart and blood vessels a period of recovery. When you regularly sleep for less than 6 hours, this natural process can be disrupted. Short sleep may increase the activity of stress hormones such as adrenaline and cortisol, which can contribute to higher blood pressure.
Normally, blood pressure decreases at night—a pattern known as “dipping.” Some people experience less of this reduction, known as a “non-dipping” pattern, which may be associated with greater cardiovascular risk. Blood pressure can also rise naturally in the morning as the body becomes more active. Understanding the relationship between sleep and BP can help you recognise why adequate, consistent sleep is an important part of heart health.
