Dr Peter Dingle, Director, Dingle Wellness - Wellness at the core of health and safety

  1. 1. Wellness at the core of health and safety. Dr Peter Dingle Dingle Wellness www.drdingle.com peter@drdnigle.com
  2. 2. Why Workplace Wellness? • We spend most of our waking hours • Has a significant affect on the mental, physical, economic and social well-being of workers • Attention and focus of workers • Make up a significant group in the population • Established communication channels • Provides a convenient, familiar physical and social setting • Direct and indirect $ return • Improve OHS outcomes • OHS responsibilty
  3. 3. The costs of poor health The cost of poor health on personal and professional productivity is high. • stress, • absenteeism, • low morale, • low productivity, • poor concentration and focus, • low output, sub-par performance, • Tardiness, and disruption of other workers (presenteeism). • Accidents /injuries and OHS
  4. 4. Hidden causes of injury/accidents • Poor Wellbeing/illness • Stress • Obesity • Sleep and fatigue • Mental health • Medication • Negative ageing
  5. 5. Accidents Incidents Injury $ Negative behaviour Negative states Poor health
  6. 6. Negative Behaviour Diet Environment Attitude Lifestyle (DEAL)
  7. 7. Negative States Stress Poor sleep Fatigue
  8. 8. Negative Health Obesity CVD High blood pressure Diabetes Mental health Alzheimer’s Negative ageing
  9. 9. Accidents Incidents Injury $ Negative mind body response Mental and physical fatigue Poor thinking, concentration, Focus Errors of omission Errors of admission
  10. 10. SLEEP“8 hours a day keeps the doctor away” Dr Peter Dingle www.drdingle.com .com
  11. 11. Sleep is not an option • Rest • Recovery • Recuperation • Repair and Growth – Immunity – Hormones Dr Peter Dingle www.drdingle.com .com
  12. 12. Health Disorders • Depression and anxiety • Cardiovascular Disease 30-100% • Diabetes 50% • Weight gain 50% • Obesity • Cancer • ADHD • One study conducted showed that sleep deprived rats died within 2-3 weeks. Dr Peter Dingle www.drdingle.com .com
  13. 13. Cognitive Effects of lack of sleep • Deterioration of performance, attention and motivation • Diminishment of mental concentration, creativity and intellectual capacity •Increased likelihood of accidents and injuries Dr Peter Dingle www.drdingle.com .com
  14. 14. Sleep problems: potential risk factor for work injuries • In total, 27 observational studies (n = 268,332 participants) that provided 54 relative risk estimates were included • workers with sleep problems had a 1.62 times higher risk of being injured than workers without sleep problems. • Approximately 13% of work injuries could be attributed to sleep problems. (Sleep problems and work injuries: A systematic review and meta-analysis, Uehli et al)
  15. 15. Grumpy boss syndrome • It is known that a lack of sleep will affect a person’s mood. • in participants who slept only 5 hours per night for 7 days their mood progressively worsened. Dr Peter Dingle www.drdingle.com .com
  16. 16. Voluntary Sleep killers • Television / telephone/internet. • Thomas Edison • Stress/ active mind • Shiftwork/irregular hours • Work: shift-work, early starts, excessive hours. • Study. • Social commitments e.g. excessive partying. • Dietary-big dinners • Caffeine • Alcohol • Medication
  17. 17. Causes of Fatigue • Medical and Illness such as anemia, Thyroid gland, Depression or grief , Persistent pain • Arthritis, including juvenile rheumatoid arthritis, Autoimmune diseases, Diabetes • Infection • Medications – sedatives or antidepressants – statins • Use of alcohol or drugs • Low fitness • Poor nutrition – Iron deficiency (without anemia), zinc, B vitamins, magnesium
  18. 18. Seven major reactions of fight-or-flight • 1. Digestion slows • 3. Heart rate and blood pressure increase • 6 Chemicals released to make the blood clot more rapidly.
  19. 19. Stress on the not so good side • Your body halts long term building projects – Digestion, – Growth – Reproduction-irregular or no female cycles • Low sperm count, decreased testosterone levels – Sexual function – Immune function, increased risk of disease – Fatigue- Wears you down wears you out – Poor sleep
  20. 20. Stressed health conditions • Migraines • Irritable bowel syndrome • Hypertension • Coronary heart disease • Diabetes • Asthma • Obesity • Cancer • Age related illness
  21. 21. Implication of Stress: Lowered Immune System. Viral infections Allergies Cancer Lupus Arthritis
  22. 22. Implications of Stress: Memory Function concentration focus accidents injury .
  23. 23. Perception Stress
  24. 24. Stress and nutrition • Increase an individual’s requirement for certain nutrients; and • there is the role of various nutrients in reducing the severity of an individual’s stress response – C, E, A and B-complex vitamins, magnesium, zinc and calcium and amino acids • Poor nutritional behaviour
  25. 25. Stress and weight gain • Cortisol • Promotes hunger • Reduces mobilisation • Releases glycocorticoids
  26. 26. Obesity increases • the risk of: – Heart disease – Stroke – High blood pressure – Type 2 diabetes – Arthritis – Breathing problems – Some cancers including endometrial, gallbladder, ovarian, breast and prostate – Age related illness
  27. 27. Obesity increases • Social stigmatism and discrimination • bullying • Sleep • Fatigue • Injury and Accidents
  28. 28. Obese workers are also at increased risk to injury (traumatic and non-traumatic) from: • Motor vehicle accidents • Falls • Strenuous exercise • Manual handling tasks • Biological agents (from reduced well being)
  29. 29. Obesity related injuries • Manual handling tasks - obese workers can have difficulty holding objects close to their bodies when lifting exposed to increased risk of injury (Thompson, 2007; Xiang, 2005). • Injuries may include Carpal Tunnel Syndrome and musculoskeletal injuries (sprains, strains, back, knee and shoulder) (Leboeuf-Yde, et al, 1999; Lievense, et al, 2002; Oliveria, et al, 1999; østbye, et al, 2007; Pollack, et a/, 2007; Thompson, 2007; Xiang, 2005).
  30. 30. Case study Physically demanding occupations • The study also showed that fire-fighters with BMI > 28.5 had a 70% increased risk of job disability and that this cohort was at particular risk of obesity related cardiovascular disease.(Soteriades et al (2008).
  31. 31. Obesogenic workplaces • Weight gain may be associated with some workplaces and practices. • Including long work-hours, high-demand and low-control pressures and extended periods of performing sedentary tasks (laIa and Pronk, 2001; Kiser, 2007; White and Jacques, 2007, Schulte et al (2007). • Such working conditions are exacerbating the effects of obesity and, in turn, increasing obesity related costs (The National Obesity Taskforce, 2005). • Loss of mobility for extended periods of time not only results in loss of opportunity for energy expenditure but it also increases risk to injury the musculoskeletal system due to sudden, rapid movement (Hamilton, et al, 2007).
  32. 32. OHS and obesity • OSH duty of care has traditionally applied to the identification and control of workplace hazards and diseases, but may have a future role in the control of workplace risks relating to obesity.
  33. 33. Mental health and injury • The researchers estimated mental health problems and psychotropic treatments might account for an "important minority" of workplace injury events (approximately one in 10). (Palmer et al 2014 Occup Environ Med doi:10.1136/oemed- 2013-101948 )
  34. 34. Exercise and depression
  35. 35. Medication and OHS • Fatigue • Sleep • Obesity • Accidents • Injury
  36. 36. Workplace wellness Thinking • A study in DuPont found a reduction of 47.5% in absenteeism and 14% fewer disability days • Mental performance was significantly better in physically fit workers compared to unfit workers. • Fit workers committed 27% fewer errors on tasks involving concentration and short term memory tasks compared to unfit workers
  37. 37. Decision making • In a 9 month study of 80 executives those who regularly worked out improved their fitness by 22% and demonstrated a 70% improvement in their ability to make complex decisions compared with non exercisers.
  38. 38. Less accidents • One study found that employees who participated in a regular fitness program had a 50% reduction in job grievances and on the job accidents and a 40% reduction in lost time.
  39. 39. Nutrition and Injury/illness recovery • Immune • Asthma • Cancer • CVD • Diabetes • Reproduction • Obesity Patient recovery Patients receiving nutrient supplementation had 70% fewer infections, fewer complications and accelerated recovery compared with controls.2
  40. 40. Why is health behavior change so hard? • “miracle drug” or “silver bullet” mentality • Too much pressure to be unhealthy • Lack of awareness/education • Lack sufficient motivation • I- don’t know how • I-don’t-care-itis • Barriers are too great to overcome • Feel overwhelmed
