Powerful emotions can be a good thing, but negative ones can have a dangerous impact on health. The common negative emotions are Anger, Loneliness, Stress, Anxiety, Sadness, and Shock.

Anger:
Many studies have shown that anger can lead to heart attacks and an increased risk of cardiovascular problems. A sudden burst of anger can cause an over-the-top surge of chemicals throughout the body, like adrenaline and noradrenaline. During a bout of anger, the brain’s amygdala overreacts; blood rushes to the frontal lobe, the area in charge of reasoning. This is why anger can often be blinding and can lead to unwanted deeds and impaired judgment.

Anger is dangerous to cardiovascular system. Many physiological changes occur in the body, when one gets angry. What researchers found was that two hours after an outburst of angry, people had nearly a five-fold increase in heart attack risk, and a three-fold risk increase for stroke.
Dr. Elizabeth Mostofsky, at the Harvard School of Public Health and a lead author of the study, says “The risk of an acute cardiovascular event with a single outburst of anger is relatively low, but the risk can accumulate for people with frequent episodes of anger”

Loneliness:
Loneliness is dangerous like a sudden outburst of anger. It’s a long-term condition, like depression, and is a risk factor for early death, according to Dr. John Cacioppo, a psychologist at the University of Chicago.

Feeling lonely can increase the risk of premature death by 14%, beyond what can be explained by poor health behaviors. It’s important to maintain social relationships with friends and family, and to even make small talk with new faces every once in a while. Older people who are lonely have a higher levels of stress, and less of an ability to adapt to difficult situations, if they don’t have anyone to lean on.

Loneliness can increase levels of stress hormones in the body like cortisol, affects sleep quality, and increases blood pressure. Isolation and solitude can weaken the immune system. So maintain friendships and social bonds will do good.

Stress And Anxiety:
Stress has a huge negative effect on our bodies. Stress always manifests as physical symptoms such as migraines, grinding teeth, lightheadedness, nausea, exhaustion, heart palpitations, insomnia, and a decreased or increased appetite. Constant stress has been linked to early aging, high blood pressure, chest pain, and a weakened immune system. People who are stressed are less likely to take care of themselves, sleep and eat properly, and thus are more likely to get sick. Stress can worsen an existing problem. Chronic stress may cause disease, either because of changes in the body or by overeating, smoking and other bad habits people use to cope with stress.

Job strain high demands coupled with low decision-making latitude is associated with increased risk of coronary disease.
Learning to reduce stress is one of the best investments on health. Exercise, eating healthy, and giving time as well as a chance to relax and unwind will go a long way.

Shock:
Shock, or trauma, can cause both short-term and long-lasting consequences both on mind and body. Shock typically involves an unexpected situation that throws an unprepared person off their feet, and leaves them unable to cope or react properly.
Psychological trauma occurs in the brain, and can actually change the structure of the brain in the area where the frontal cortex, emotional brain and survival brain converge. Physical symptoms that occur due to shock or post-traumatic stress disorder (PTSD) include sleeping and eating issues, sexual dysfunction, lack of energy, and chronic pain.

Sadness:
It’s called heartbreak for a reason. A deep grief or sadness, takes a toll on the health. One study from St. George’s University of London found that it is actually possible to die of a broken heart. Sadness increases the risk of a heart attack or stroke by nearly double after a partner’s death. The term ‘broken heart’ is used to signify the pain of losing a loved one and studies show that bereavement can have a direct effect on the health of the heart.
