Quality Innovation Education Is modern life fracturing Alessandro Ferretti Stress - Modern day epidemic Work-related stress, depression or anxiety accounted for 39% of all work-related illnesses in 2013/141.
The UK annual total of working days lost due to stress, depression or anxiety is 11.3 million1 The WHO estimate that up to 70-90% of doctor's visits are for stress related issues2 1.Stress-related and Psychological Disorders in Great Britain 2014 Health and Safety Executive Oct 2014 2.

"Everyone knows what stress is, but nobody really knows" Hans Seyle Selye defined stress as "the non-specific response of the body to any demand for change".
It is important to differentiate between the unpleasant or harmful variety
of stress - distress, and positive stress or eustress.
With both forms of stress, the body undergoes virtually the same non-specific responses to the various positive or negative stimuli. However, eustress causes much less damage than distress. Stress and performance Increased stress results in increased productivity…up to a point After which things go rapidly downhill. That point or peak differs for each of us. Stress is difficult to define because it is so different for each of us. Top causes of stress in the US • Job Pressure Co-worker tension, bosses, work overload Loss of Job, Reduced Retirement, Medical Expenses Health Crisis, Terminal or Chronic Illness • Poor Nutrition Divorce, Death of Spouse, Arguments with Friends, Loneliness • Media Overload Inadequate Nutrition, Caffeine, Processed Foods, • Sleep Deprivation Top Causes of Stress in the US American Psychological Association, 07.08.2014 Worrying yourself sick Animals deal mostly with acute physical stressors.
"Psychological stress is a recent invention - we humans can experience wildly strong emotions linked to mere thoughts."1 Worrying can activate the stress response in anticipation of stressful events.
1. Sapolsky RM Why Zebras don't get ulcers 1998 US Stress -fracturing our health Stress and Immunity Nearly 80 years ago Selye presented evidence for stress-induced immunosuppression via atrophy of the thymus gland.
We now know that chronic stress is associated with a greater risk of autoimmune diseases, upper respiratory infections, and poorer wound healing1,2,3.
1. Cohen S et al JAMA 2007,298:1685–1687 2. Cohen S et al Psychosom Med 1999 61:175–180. 3. Stone AA, et al. Behav Med 1992 18:115–120. Does stress help or hinder? Short-term stress up regulates natural immunity - requiring minimal time and energy investment to act against invaders1. − In evolutionary terms, these changes prepare the organism for infections resulting from bites, puncture wounds, scrapes or other challenges to the integrity of the skin and blood. − This process would be adaptive and did not divert excess energy from fight-or-flight behaviour2. Long-term stress suppresses or dysregulates both innate and adaptive immune responses: − Disturbs cytokine balance, induces low-grade chronic inflammation, and suppresses numbers and function of immuno-protective cells3. − Chronic stress may increase susceptibility to some types of cancer by suppressing Type 1 cytokines and protective T cells3.

Dhanhar FS Immunol Res. 2014;58(2-3):193-210. 3.Canetti D et al J Trauma Stress 2014 27 (3):345-52 Stress and circulation Chronic stress hammers away at the cardiovascular system, basically making it work harder and harder.
With the increase in blood pressure that accompanies repeated stress, damage occurs at branch points of the arteries.
Adrenaline triggers changes to enhance blood clotting.
These changes contribute to the development of atherosclerosis1. 1.Dekker M.J.H.J et al. J Clin Endocrinol Metab. 2008;93:3741–3747 When the adrenal glands are fatigued they continue to function, but hormones can: − become depleted.
− lose balance with each other.
− lose circadian rhythm.
A growing body of scientific research indicates that stress can have profound effects on sleep. Compared to those not experiencing insomnia, insomniacs have a greater number of stressful life events in the previous year1.
1. Hall M et al Symptoms of stress and depression as correlates of sleep in primary insomnia Psychosomatic The circadian rhythm of cortisol is regulated by the sleep-wake cycle.
Secretions are characterised by a steep increase in the morning, followed by a gradual tailoring off until about midnight (circulating levels are at their lowest).
"A clear diurnal pattern of low cortisol excretion at night that increased some x7 in the morning was reproducibly identified in healthy control subjects"1 1. Burch W Endocr Pract. 2011;17(4):591-7. Stress and Energy The adrenal hormones are integrally involved in how energy is produced and where it is allocated.
When blood glucose levels drop, the adrenals release cortisol which triggers the liver to produce more glucose.
Cortisol increases the amount of glucose available to the brain and muscles and limits energy supplied to digestion, growth and reproduction (nonessential, or even detrimental in a survival situation).
Adrenal fatigue and blood sugar 1. Lam M Adrenal Fatigue Syndrome www.Drlam.com Adrenals mobilise energy When faced with a stressor: − sympathetic nervous system turns down insulin secretion to stop energy storage.
− secrete glucocorticoids to block transport of nutrients.
− glucagon, adrenaline & noradrenaline liquidate assets to turn stored nutrients into cash.
− making this ‘withdrawal' means that there is now plenty of energy available for muscles to respond to the crisis.
1. Sapolsky R M Why zebras don't get ulcers 1998 W H Freeman and Co USA So where's the problem? ….it's inefficient! Withdrawing money early from savings and investments typically incurs a penalty. In the same way, every time you store energy away from the circulation and then return it, you lose a proportion of the potential energy.
Activate the stress-response too often, and you will expend so much energy on making energy that you'll end up fatigued.
1. Sapolsky R M Why zebras don't get ulcers 1998 W H Freeman and Co USA Stress and fertility In men, psychological stress lowers serum testosterone levels and alters quality of sperm (reduced motility & morphology)1.
In women, higher levels of stress are associated with a longer time-to-pregnancy and an increased risk of infertility2 1. Bhongade MB et al Andrologia. 2014 Mar 26. 2. Lynch CD et al Hum Reprod. 2014;29(5):1067-75.
Stress and Cognition Chronic stress clouds the ability to think clearly.
Investigators found that in response to repeated stress, there was a significant loss of glutamate receptors.1 Glutamate signalling plays a significant role in the functioning of the pre-frontal cortex.
This is a region of the brain that controls high level "executive" functions such as working memory and decision-making.
1.Yeun EY et al Neuron 2012; 73(5): 962–977.
Stress and Digestion Stress alters gastroduodenal motility, slows gastric emptying, and unsettles intestinal transit and colonic motility1.
Stress has negative effects on the vagal nerve providing a pathway through which negative emotions may influence gut function and health2.
Vagal activation directly and profoundly influences metabolic responses to food and is a key factor in the regulation of glucose metabolism3. 1.Yin J et al Neurogastroenterol Motil. 2004;16:737–44. 2.Pieper S et al Psychosom Med. 2007;69:901–9 3.Teff KL. Journal of Parenteral and Enteral Nutrition. 2008;32:569–71. Stress and the microflora Stress, linked to imbalances in HPA, has been shown to alter the composition of gut flora.1 Researchers compared the response of the HPA axis to stress in germ free mice compared with those with a normal flora. Stress caused an exaggerated ACTH & corticosteroid reaction in germ free mice.2 This hyper reaction was reversed by administration of Bifidobacterium infantis.3 1. O'Mahony et al Biol Psychiatry 2008;65:263-267 2. Sudo et al J Physiol 2004;558:263-275 3. O'Mahony et al Gastroenterology 2005;128:541-551 Fracturing our health Continual over-activation of the stress response without compensatory relaxation and recovery can turn a survival mechanism into one that has potential to cause harm. Stress has been linked to the 6 major causes of death1 1. Actor S Make Stress Work for You Feb 15, 2011 Harvard Business Review Can we change our response to stressors? Is stress inevitable? "Between stimulus and response ……there is a space. In that space is our power to choose our response" Identifying a problem You feel tired for no reason.
You have trouble getting up in the morning, even when you go to bed at a reasonable hour.
You are feeling rundown or overwhelmed.
You have difficulty bouncing back from stress or illness.
You crave salty and sweet snacks.
You feel more awake, alert and energetic after 6PM than you do all day.
1. Wilson JL Adrenal Fatigue - the 21st century stress syndrome 2001 Smart publications Petaluma CA Limitations of Adrenal Stress Index ASI gives a snap shot of hormonal response to stress.
Glucocorticoid resistance can develop in a similar way to insulin or leptin resistance.
Cellular receptivity to cortisol is probably more significant than circulating levels of cortisol1.
Heart Rate Variability and glucose monitoring can be more useful tools to monitor stress response if used on an on-going basis.
1. Cohen S et al PNAS 2012, 109(16) Dietary essentials Both laboratory and epidemiological studies suggest that stressful events motivate less healthy food choices1 Aim to keep blood sugar levels steady - preferably monitor regularly. − Fruit eaten in moderation and not in isolation.
− Swap processed & refined foods, (especially those containing sugar and artificial sweeteners) for natural wholefoods .
− Caffeine elevates cortisol & adrenaline levels both at rest and in periods of stress2 - replace with non caffeine containing herbal teas (esp. liquorice and green) and water. − Include at least 6-8 portions of vegetables daily - paying particular focus to dark green leafy and non-starchy vegetables. Include multiple sources of essential fats such as oily fish, flaxseeds, walnuts, almonds, hemp and chia seeds.

Re-establish a healthy circadian rhythm - asleep by 11pm at latest.
Exercising inappropriately can be an additional stressor - the physical stress of training when exhausted, or overtraining, may cause adrenal hormones to become depleted1. Use HRV to plan training sessions.
Adjust training schedule accordingly - walks in nature, pilates and tai chi etc Monitor heart rate variability to learn how emotions effect stress levels. Deep breathing techniques can be useful to help manage stressful situations2. A study at Harvard Business School asked employees to take one full day off during the week, and also unplug completely from work at night (no emails etc). The study showed that employees were more satisfied with their jobs, AND more productive.3 1.Brooks KA & Carter JG J Nov Physiother 2013;3(125):11717 2. www.heartmath.com 3 Perlow LA and Porter JL Making Time Off Predictable—and Required Harvard Business Review Oct 2009 Supporting your genes Genetic testing can help to identify individuals who may be more susceptible to the damaging effects of chronic stress: − Susceptibility to increased HPA and glucocorticoid response− Compromised methylation − Increased glutamic acid/GABA ratio− Increased blood glucose level in response to stress− Poor degradation of neurotransmitters.
− For these individuals, the learning of appropriate life load, self care and nutrition skills is essential. Nutrients for Glucocorticoids L-Citrulline has been shown to have therapeutic effects on nitric-oxide levels.
Licorice - triterpines in licorice metabolise into molecules with similar structure to adrenal cortex hormones1 potentiating cortisol by reducing its breakdown2. Stress response was partially blocked and adaptation enhanced in rats given glycyrrhizic acid for 10 days.3 Vitamin C - a key antioxidant that is needed in larger quantities during times of stress. Studies have demonstrated how psychological stress induces oxidative damage.4 Panax Ginseng - an adaptogenic herb with anti-fatigue properties5. It has been shown to improve energy, stamina & mental performance6 Chromium mobilises the glucose transporter to the inner cell surface membrane.7 It improves insulin binding, insulin receptor number, insulin internalisation, beta cell sensitivity and insulin receptor enzymes with overall increases in insulin sensitivity8 Vitamin B39 and magnesium10 support blood sugar regulation.

Lemon balm - supplementation with lemon balm extract has been shown to promote a significant increase of calm in the individual along with a reduction in the state of anxiety and insomnia2.
L-Tryptophan - is an essential amino acid acting as a building block for protein biosynthesis. It is a precursor for serotonin, melatonin and also niacin3.
L-Theanine - is a physiologically and behaviourally active compound. It increases serotonin and dopamine production in the brain, and elicits selective changes in alpha brain wave activity4. Magnesium taurate - magnesium supplementation reduces HPA overactivity and improves sleep patterns5.
