Mind-Body Connection: How Emotions Affect Your Overall Health and What To Do About It

by Kristen Fisher

When I was still a child, I remember my mother asking if I was having trouble at school when I complained of a headache one morning in a bid to stay home that day. Of course, at the time I didn’t understand that she was asking me this question as there is a direct relationship between our mental and physical health.

Over the years, however, I have come to understand the mind-body connection. For example, your face flushes red as warm blood flows towards it when you feel embarrassed, or sometimes you get a funny feeling in your tummy when you feel anxious or nervous. However, these are harmless emotional changes that may not cause much harm. But, extreme changes in emotional health can have severe implications on your body.

Here is how emotions affect your health and what you can do to keep them under control.

1. Increased Risk of Cardiovascular Diseases

Various mental illness and disorders have long been associated with cardiovascular diseases. However, what people have known instinctively for decades has been proven scientifically as well. According to a recent study published by King’s College London, severe mental illnesses are linked to a much higher risk of cardiovascular diseases.

The study comprised over 3.2 million patients and more than 113 million people from the general population. It revealed that the risk of developing cardiovascular diseases goes up by almost 53% among people suffering from various mental ailments such as schizophrenia, bipolar disorder, and major depression compared to their healthy counterparts. The risk becomes much higher (78%) over the longer term.

Angry outbursts, on the other hand, may last for just a few minutes. But, they are also associated with heart attacks, particularly when accompanied by stress. According to a study conducted by researchers from the University of Sydney in Australia, in the 2 hours after a period of intense anger, the risk of heart attack may increase 8.5 times.

Individuals who experience high levels of anxiety in the 48 hours before the onset of symptoms of heart attack are 9.5 times more likely to suffer it within the following 2 hours. “Episodes of anger or anxiety can cause increased heart rate, high blood pressure, narrowing of blood vessels and increased clotting, all of which can be heart attack triggers,” says lead author Dr. Thomas Buckley.


2. Increased Cancer Death Risk

A study published earlier this year states that anxiety and depression may be linked to increased cancer death risk. The researchers looked at the mental health of more than 160,000 adults in England and Wales that were free from cancer at the beginning of the study.

The average 10-year follow-up found that people with the highest levels of mental distress were 32% more likely to have died of cancer, particularly colon, prostate, and pancreatic cancers. The researcher adjusted the figures for potential factors such as age, sex, body mass index, educational attainment smoking, and alcohol consumption that could affect the data. However, the study supports the growing evidence that physical and mental health are related to each other.

Another study involving a systematic review and meta-analysis of the data from 1,469,179 participants and 89,716 incident cases of cancer from 25 studies also found an association between depression and the overall occurrence risk of cancer, particularly liver and lung cancers.

3. Increased Risk of Developing Type-2 Diabetes

In 2015, 30.3 million Americans or 9.4% of the population had diabetes, of which 7.2 million (23.8%) were not aware of it. It was also the seventh leading cause of death in 2015. In the recent years, the relationship between stress and diabetes has been confirmed by various scientific studies. One of the most recent studies, published by a team of Australian researchers has established that stress increases the risk of Type-2 diabetes in women.

The study focused on more than 12,000 women from the 1946–1951 cohorts who completed surveys for the Australian Longitudinal Study on Women’s Health in 1998, 2001, 2004, 2007 and 2010. Moderate-to-high stress levels increased the odds of diabetes by 2 to 3 times after three years. It was found that perceived stress can influence smoking, hypertension, physical activity and body mass index, either directly or indirectly. All of these factors ultimately increase the risk of diabetes.
