Are you stressed? If so, your chances of heading to an early grave are significantly higher.
New research has found that people who reported feeling anxious and overwhelmed were 27 per cent more likely to suffer a heart attack.
The study, led by Columbia University Medical Centre researchers, was published in the American Journal of Cardiology.
The researchers looked at six previous studies where people had been asked about their perceived stress with questions such as ‘how stressed do you feel?’ and ‘how often are you stressed?’.
The groups were separated into high and low stress scores and then followed for 14 years to track the number of heart attacks .
Those who were the most stressed were 27 per cent more likely to have a heart attack.
The effect of stress was so profound that the researchers compared it to smoking more five cigarettes a day.
It was also likened to a 2.8mmol/l increase in LDL cholesterol and a 2.7/1.4 mmHg increase in blood pressure.
The British Heart Foundation says that people who are at high risk of, or already have, heart disease should aim for an LDL cholesterol level under 2 mmol/l.
Therefore, it says the figures suggest a 2.8mmol/l rise is more than double the recommended cholesterol levels for heart and stroke patients.
A healthy blood pressure reading should be below 140/90mmHg.
LDL cholesterol is considered a risk for heart disease that can lead to heart attack because it contributes for narrowing of the arteries that supply blood flow to the heart from plaque buildup, or atherosclerosis.
Higher blood pressure puts stress on the heart and contributes to stiffening of the arteries, making them more susceptible to blockage. It is thought to be responsible for 50 per cent of all heart attacks and strokes.
The researchers did further analysis to try to learn what might unpin the link between stress and heart disease. They found that while gender was not a significant factor, age was.
Among older people, the relationship between stress and CHD was stronger, suggesting the effects of stress compound over time.
They also noted that older people tend to have worse risk factors such as high blood pressure and raised cholesterol to begin with, and that stress may interact with those risk factors to trigger a heart attack.
‘These findings are significant because they are applicable to nearly everyone,’ said study author Safiya Richardson.
‘The key takeaway (message) is that how people feel is important for their heart health, so anything they can do to reduce stress may improve their heart health in the future.’
Her co-author, Donald Edmondson, assistant professor of behavioural medicine at CUMC added: ‘This is the most precise estimate of that relationship, and it gives credence to the widely held belief that general stress is related to heart health.’
Heart disease is Britain’s biggest killer. Around 270,000 people in the UK suffer a heart attack every year and and nearly one in three die before they reach hospital.

We need stress for without it we'd have no motivation to do anything. Imagine this scenario: you've suddenly acquired a vast amount of money on the lottery, riches beyond your wildest dreams. So what's the first thing you do? likelihood you give up your job, people often find their jobs as stressful. You've got enough money so you don't need to work. That makes you feel less stressed, or so you think. Of course you buy the big house, the cars, the boat, designer wardrobe and you party. You really think you have it made. There comes a point though when you can have anything you want, you don't have to work for it, there's no sense of achievement, no goal in sight. You don't have to cook or clean what do you do all day? eventually you will run out of ideas and you will become bored, you will have no motivation to do or achieve anything. Stress is a catch 22 situation if you have no motivation, you become depressed and bored, the days are long that equals stress. So a certain amount of stress is necessary to motivate us and stimulate us and give us a reason to be here and a sense of accomplishment this can be seen simply as this:
Stress = Motivation > Stimulation > Accomplishment = Satisfaction
Stress The dictionary definition of stress is: a constraining or impelling force, effort or demand upon physical or mental energy. A stressor is a person or situation that makes you become stressed. We are more likely to suffer stress in society today than that of our ancestors. 70% of all illness to day is now directly attributed to stress. Modern society with all its pressures traffic congestion, over-crowding, noise, fears and general uncertainties about work, mortgages and family life present situation after situation where the state of stress is ever present. Stress is an everyday part of modern life, everyone experiences at sometime or another and everyday stresses are not necessarily harmful. A certain about of stress keeps us motivated and stimulated to make life more enjoyable and interesting. It is the effect of long-term stress that can be positively harmful to our bodies.
When do stress levels become harmful?
The factors that seem to make any situation dangerously stressful are:
• Lack of predictability
• Lack of control
• Lack of outlets for frustration
For when these elements are present even simple situations can become stressful and produce a reaction that is completely out of proportion to the cause. It is not the situation but our reaction to it that creates the stress in our lives. The problem with us humans we have this tendency to dwell on the past and worry about the future and this takes our attention away from the present. Yet it is in the present moment that we have the greatest clarity to deal with any situation. We should enjoy our life in the present for in holding on to the past and holding back the future we create fear and ultimately stress. Growth in our lives is usually preceded by change the problem is handling change can be difficult in the short term and life-changing events such as:
• Bereavement
• Moving House
• Debt
• Ill Health
• Difficult Relationships
• Stressful Work
• Family Problems Have been identified as the most likely to cause negative or harmful stress.
Even positive events such as:
• Marriage
• Pregnancy
• A child starting school or University May cause you stress and can ultimately lead to illness.
Your personality and coping mechanisms will largely determine how you deal with these daily stresses and strains.
WHAT HAPPENS TO US WHEN WE ARE STRESSED?
Well this goes way back to the times when we were developing as humans and in early periods in history. The body's chemistry was designed to protect us with "The fight or flight response". For example man sees a big bear approach what does he do? he either tackles it or he runs off. Nature is very clever and gives us the capacity to do this. However in 2011 we no longer have the bears, wolves, etc. (ok some of you may) like of yesteryear we have different stresses. Your work colleagues or your neighbours may annoy you but you can't fight them, nor can you run away, but you can learn to deal and dissipate your stress levels so that it doesn't impinge on your health.
But firstly we need to deal with the science bit for if we understand the physiology of stress we're half way there to solving the impact stress has on our lives.
THE SCIENCE BIT
Deep within the brain we have an area known as the Hypothalamus (1), its the home of our moods and emotions and a very primitive part of the brain. The Hypothalamus is also the area that maintains equilibrium in our bodies and it maintains and regulates every bit of our body's chemistry. It is the area that controls the Endocrine system, it forms part of the Autonomic Nervous System and part of the Limbic System. It is Hypothalmus that is the key to managing stress and all its detrimental effects on our mind and body. It is directly through this area that the holistic therapy Aromatherapy works and is managed by other holistic therapies.
Since the Hypothalamus is the home of moods and emotions anything that affects these will influence the Hypothalamus, thus will have an effect on the body's equilibrium.
Now if we are stressed and modern stressors are not the same as those stressors we had as we were evolving as humans, they still have the same effect resulting in "the fight or flight response"
(1)The Role of the Hypothalamus
The Hypothalamus is the part of the brain that controls the endocrine system.
The Pituitary gland lies beneath the Hypothalamus and it is this that controls the other endocrine glands.
The Hypothalamus receives information about the Homeostasis (balance) of the body, this is achieved by two means:
- The blood circulation i.e. temperature, blood glucose levels and hormone levels
- The nervous system i.e. The Autonomic Nervous system i.e. the part of the nervous system that regulates automatic functions e.g. breathing, heart rate etc. and mental and emotional states, our feelings: these influence ‘automatic responses’ e.g. ‘The fear, flight response’
The Hypothalamus responds to these changes by:
- Secreting Hormones (chemical messengers) that regulate hormones to be released by the anterior lobe of the pituitary
- The hypothalamus also directly releases hormones via the Posterior Lobe of the Pituitary , Vasopressin (ADH) and Oxytocin
- And by stimulating a nerve response to the ‘Central Nervous System’ (Brain & spinal Cord)
SO WHAT HAPPENS IN THE FIGHT OR FLIGHT RESPONSE?
Moods/emotions affect the hypothalamus, the hypothalamus evokes a reaction on the anterior lobe of the pituitary gland. The pituitary gland produces Adrenocorticotropic hormone this in turn targets the adrenal glands causing them to secrete Cortisone, Cortisone in turn effects the kidneys causing a rise in blood pressure by causing changes in the amount of salt secreted, this hormone causes the body to retain salt. Now remember the Hypothalamus one of its jobs is to maintain the body's equilibrium, it detects a rise in salt levels in the blood so to keep balance it causes the body to retain fluid, it is this retained fluid that increases blood pressure. At the same time, the Hypothalamus being part of the Central Nervous System evokes what is known as the Sympathetic Nervous System this diverts blood away from the digestive system and to lesser important body structures such as the skin and concentrates the blood to the heart, lungs and muscles. Simultaneously this nervous response influences the adrenal glands to produce Adrenalin and Noradrenalin, it is these hormones that induces vasoconstriction (reduces the blood supply) to the skin and peripheral tissues, thus also raising blood pressure.
Now this is putting it simply there are a few other processes also going on to increase blood sugar to give the body fuel to either run off or fight, Corticotrophic hormones influence the pancreas to secrete glucagon this has the opposite effect as insulin.
When the stress is over the Parasympathetic Nervous reverses the process again it is the Hyptholamus that instigates this.
Obviously its much more complex than this and I have focused on a few key hormones as it the action of these hormones that affects our well-being, the ageing process and blood pressure.
The fight or flight response was not designed to last forever it was meant ti instigate an action to deal with an aggressor, be it a wild animal or in a fight with an attacker therein lies the problem modern stressors tends to be work, work colleagues etc. the stress becomes long acting, this kind of reaction is fine in the short term but very detrimental to the body in the long term.
Take Cortisone, it has a damaging effect on specialised cells within the dermis (the skin), fibroblasts, these cells produce collagen and elastin, it is collagen and elastin that gives our skin elasticity and support. Adrenalin reduces blood supply to the peripheral tissues, such as the skin and hair, therefore, these structures do not receive adequate nourishment from the blood. So the effect of long term stress affects the skin resulting in ageing of the skin
