Excessive stress and sleep deprivation can cause cardiovascular issues, such as high blood pressure and heart disease. In a study focusing on the impacts of chronic stress on the heart, it was found that during times of chronic stress, the body hyperactivates the sympathetic nervous system which leads to changes in heart rate variability.

The decrease in systolic blood pressure, diastolic blood pressure, and heart rate signal a state of calmness, which is essential for having a good night sleep. Sedative music, which is characterized by a slow tempo, repetitive rhythm, gentle contours, and strings, is effective in generating anxiolytic responses to aid sleep.
This increases your heart rate and blood pressure while mobilizing glucose (blood sugar) stores to give you a surge of energy. In simple terms, these hormones help you handle the perceived threat by :
A medical monitoring device displaying a normal human heart rate. Heart rate is the frequency of the heartbeat measured by the number of contractions of the heart per minute (beats per minute, or bpm). The heart rate varies according to the body's physical needs, including the need to absorb oxygen and excrete carbon dioxide.

"This hormonal surge increases blood pressure and heart rate and can put an ongoing strain on your cardiovascular system, causing angina or a heart attack." That's not the only thing it does.
The human organism physically restores itself during sleep, occurring mostly during slow-wave sleep during which body temperature, heart rate, and brain oxygen consumption decrease. In both the brain and body, the reduced rate of metabolism enables countervailing restorative processes. [ 97 ]
