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.

In patients with stable coronary heart disease (CHD) up to 70% [1] Mental stress-induced myocardial ischemia (MSIMI) is a medical condition in which acute psychological stress can trigger a transient myocardial ischemia , which is a state of reduced blood flow to the heart muscle , often without the presence of significant coronary artery ...

Sleeping in the lateral, or side position, as compared to sleeping on one’s back or stomach, may more effectively remove brain waste and prove to be an important practice to help reduce the ...

Normal heart rates vary with age and level of fitness, from infants having faster heart rates (110-150 bpm) and the elderly having slower heart rates. [3] Sinus tachycardia is a normal response to physical exercise or other stress, when the heart rate increases to meet the body's higher demand for energy and oxygen, but sinus tachycardia can ...
A resting heart rate of 100 beats per minute or an increase in heart rate of 100 beats per minute with minimal exertion; Excluding any potential secondary causes of sinus tachycardia; Ruling out atrial tachycardias; Palpitations or presyncope (or both) symptoms that have been clearly linked to resting or easily induced sinus tachycardia.
