Stress, the body and disease
Stress, the body and disease
Stress is the body’s reaction to harmful situations – whether they’re real or perceived. When you feel threatened, a chemical reaction occurs in your body that allows you to act in a way to prevent injury. This reaction is known as “fight-or-flight” or the stress response. During the stress response, your heart rate increases, breathing quickens, muscles tighten, and blood pressure rises and your bloodstream is flooded with hormones such as cortisol and adrenaline. It’s a built-in physiologic response to a threat. It is how you stay alive.
Research shows that almost every system in the body can be influenced by chronic stress. When chronic stress goes unreleased, it suppresses the body’s immune system and ultimately manifests as illness.
Studies have found that there are many health problems related to stress. Stress seems to worsen or increase the risk of conditions like obesity, heart disease, Alzheimer’s disease, diabetes, depression, gastrointestinal problems, and asthma. 
What Are the Symptoms of Stress?
Stress can affect all parts of your life, including your emotions, behaviours, thinking ability, and physical health. No part of the body is immune. But, because people handle stress differently, symptoms of stress can vary.
Emotional symptoms of stress include:

Work Related Stress
There is a growing concern about the increasing cost and prevalence of stress-related disorders in relation to work place. “Worked to death, drop death, work until you drop” are highlighted “work-related death” in the 21st century.  Japan and China have been renowned for their long working hours even have a word for death by overwork they are:
Facts On Work Related Stress 
- Japan and Korea recognise suicide as an official and compensatable work-related condition
- The estimated prevalence of stress and stress-related conditions in the United Kingdom rose from 829 cases per 100,000 workers in 1990 to 1,700 per 100,000 in 2001/2002. In that year, 13.4 million lost working days were attributed to stress, anxiety or depression, with an estimate 265,000 new cases of stress.
- The latest HSE (Health and Safety Executive) analysis of self-reported illnesses rate revealed that stress, depression or anxiety affects 1.3% of the workforce
- It is estimated that 80% to 90% of all industrial accidents are related to personal problem and employees’ inability to handle stress
- The European Agency for Safety and Health at work reported that about 50% of job absenteeism is caused by stress
Diseases Linked To Stress
When you are stressed, your body produces an influx of hormones that cause your heart to beat faster and your blood vessels to narrow. This results in a temporary spike in your blood pressure. When this occurs frequently, damage to your blood vessels, heart and kidneys result. Coronary Heart disease (CHD) has long been regarded as a classical psychosomatic illness in that its onset or course was influenced by a variety of psychosocial variables. Psychosocial aspects of CHD had been studied extensively and there is strong evidence that psychological stress is a significant risk factor for CHD and CHD mortality. 
Stress causes higher levels of the hormone cortisol and that seems to increase the amount of fat that’s deposited in the abdomen. Research has also shown that those with persistent high levels of the stress hormone cortisol weighed more, had a higher body mass index (BMI) and a larger waist compared with those who had low levels of the hormone. 
A study published in July in Biological Psychiatry, women who had one or more stressful events during the previous 24 hours burned 104 fewer calories in the seven hours following a fast-food meal than women who ate a similar meal but were stress-free. 
High Blood Pressure & Diabetes
Consistently high blood sugar levels can wreak havoc on your health, with symptoms including: increased thirst and urination, blurred vision, light-headedness, flushed skin and restlessness. Some studies go so far as to suggest extreme stress can increase your risk of developing diabetes. One found that men with prolonged stress have a 45% higher risk of developing the condition. 
Stress is considered one of the most common triggers for headaches and migraines. An occasional tension headache is usually set off by a single stressful event, but if you suffer from chronic stress, you may also get chronic tension headaches. This cycle of pain itself is a big stress factor, and can make the stresses of daily living feel even worse. 
It’s probably no surprise that chronic stress is connected with higher rates of depression and anxiety. “One survey of recent studies found that people who had stress related to their jobs – like demanding work with few rewards – had an 80% higher risk of developing depression within a few years than people with lower stress.” 
Stress throws several brain neurotransmitter systems; such as serotonin, dopamine and norepinephrine; out of balance, negatively affecting mood, appetite, sleep and libido. Some severely depressed people have permanently elevated cortisol levels, which can eventually alter the hippocampus and permanently damage brain cells. Depression truly is an illness that changes the brain. 
Stress is a common factor in many GI conditions, such as chronic heartburn (or gastroesophageal reflux disease, GERD) and irritable bowel syndrome (IBS).
One animal study found that stress might worsen Alzheimer’s disease, causing its brain lesions to form more quickly. In addition, another study found that stressful life experiences (eg. being fired, declaring bankruptcy, death of a parent or financial loss) can each age the brain by around 1.5 years, with age obviously being a contributing factor in the onset of the condition. Some researchers speculate that reducing stress has the potential to slow down the progression of the disease. 
There’s actually evidence that stress can affect how you age. A study compared the DNA of mothers who were under high stress — they were caring for a chronically ill child — with women who were not. Researchers found that a particular region of the chromosomes showed the effects of accelerated ageing. Stress seemed to accelerate ageing about 9 to 17 additional years. 
Sexual desire & Reproduction
Chronic stress, ongoing stress over an extended period of time, can affect testosterone production resulting in a decline in sex drive or libido, and can even cause erectile dysfunction or impotence.”Chronic stress can also negatively impact sperm production and maturation, causing difficulties in couples who are trying to conceive. Researchers have found that men who experienced two or more stressful life events in the past year had a lower percentage of sperm motility (ability to swim) and a lower percentage of sperm of normal morphology (size and shape), compared with men who did not experience any stressful life events.”  Stress can negatively impact a woman’s ability to conceive, the health of her pregnancy, and her postpartum adjustment.
At-Home Tips for Effective Stress Management
There are both short-term and long-term strategies that are most effective when practiced consistently. These tips are most effective when practiced consistently, they are cost little or are free and accessible for most people.

Exposure to morning sunlight profoundly benefits mood, mental health, and overall sleep hygiene. Getting out in the natural light upon waking supports your body’s built-in circadian rhythm, which regulates energy levels, mood, and sleep.
Eat a balanced diet
A poor diet, or one high in processed foods, can bring about a more intense reaction to daily stressors both big and small. Eating a healthy and balanced diet will do wonders.
This can help you address negative self-talk patterns that may also be contributing to high chronic stress.
Deliberate Cold Exposure
(cold showers, cold therapy, ice baths, cold plunging, cryotherapy)
While non-conventional, the practice of intentionally exposing the body to very cold (20 degrees C) temperatures for a short period of time may be one of the most cutting edge strategies for improving health and mitigating your physiological response to stress.
It also helps to:

Tai chi or yoga
A mind-body practice that helps unify your thoughts and movements by focusing on how you move your body through space. Tai chi has been shown to improve mental health conditions such as anxiety, depression, insomnia, PTSD, and more.
Yoga is another form of movement that has been shown to alleviate stress by decreasing cortisol levels in the body. Yoga also increases serotonin production which makes us feel better overall.
Focus on belly breathing
Your diaphragm is connected to your vagus nerve, which, when stimulated, can promote relaxation in the brain.
Cut out stressors
Set boundaries in your personal life, stick to your routine during trying times, or just reducing the number of commitments on your to-do list.
Also limiting how much you watch the news, how much time you spend online or on your digital devices, limit alcohol intake, and limit your caffeine intake.
