Researchers from the University of South Australia have found another reason why society should pay more attention to mental health: it is closely linked to blood pressure and heart rate variations.

Darwin’s Exclusive Tree of Life (just think.) Sci-Tee is only in the Scientific Inquirer!

New study published in Biomedical Engineering conducts a link between mental illness and extensive blood pressure fluctuations that can lead to cardiovascular disease and organ damage.

UniSA researcher Dr. Renly Lim and colleagues from Malaysian universities say there is clear evidence that mental illness interferes with the body’s autonomic functions, including blood pressure, heart rate, temperature and respiration.

“We reviewed 12 studies of people with anxiety, depression and panic disorders and found that, regardless of age, mental illness is significantly associated with greater variations in blood pressure during the day,” says Dr. Lim.

“We also found that in people with mental illness, the heart rate does not adapt to external stressors as it should.

“Contrary to many people’s beliefs, a healthy heart is not something that beats like a metronome. Instead, it must adapt to environmental and psychological problems. The ever-changing heart rate is actually a sign of good health. ”

Decreased heart rate variation (HRV) is common in people with mental illness and indicates that the body’s stress response is poor, exacerbating the negative effects of chronic stress.

Unlike a person’s heart rate – how many times a heart beats per minute – which is usually homogeneous, HRV is more complex and represents the time between two heartbeats, which should vary depending on external stressors.

“We are not striving for a constantly changing heart rate, but for a high change in heart rate. This is achieved through a healthy diet, exercise, low stress and good mental health.

Low HRV occurs when the human body is in a “beat or run” mode, is easily stressed and is common in people with chronic diseases, including those with cardiovascular and mental health problems.

While large fluctuations in blood pressure (BPV) during the day are not ideal, at night systolic blood pressure should drop by 10-20 percent to allow the heart to rest. Researchers have found that people with mental health problems do not have enough blood pressure at night.

Decreased immersion – less than 10 percent – can be caused by many factors, including autonomic dysfunction, poor sleep quality, and disrupted circadian rhythms that regulate the sleep-wake cycle.

“The conclusion from this study is that we need to pay more attention to the physical consequences of mental illness,” says Dr. Lim.

“This is a major global burden that affects 11 to 18 percent (one billion) of people worldwide. Because mental illness can contribute to impaired regulation of heart rate and blood pressure, early therapeutic intervention is very important. ”
