Listening to Music Before Bed

Listening to Music Before Bed

According to Science Daily, Dr Naresh Sen, study author, Consultant Cardiologist at HG SMS Hospital, Jaipur, India, said: “We use music therapy in our hospital and in this study we showed that yoga music has a beneficial impact on heart rate variability before sleeping.”

Previous research has shown that music can reduce anxiety in patients with heart disease. However, studies on the effects of music on the heart in patients and healthy individuals have produced inconsistent results, partly they did not state what style of music was used.

The body’s heart rate changes as a normal response to being in “fight or flight” or “rest and digest” mode. These states are regulated by the sympathetic and parasympathetic nervous systems, respectively, and together comprise the autonomic nervous system. High heart rate variability shows that the heart is able to adapt to these changes. Conversely, low heart rate variability indicates a less adaptive autonomic nervous system.

Low heart rate variability is associated with a 32-45% higher risk of a first cardiovascular event. Following a cardiovascular event, people with low heart rate variability have a raised risk of subsequent events and death. Failure of the autonomic nervous system to adapt may trigger inflammation, which is linked to cardiovascular disease. Another possibility is that people with low heart rate variability already have subclinical cardiovascular disease.
