Aches & Pains - Back and neck pain — a common result of worry, stress

and depression — is an important cause of productivity loss (Loeppke, Taitel et

al., 2009), and contribute significantly to absenteeism and presenteeism (NIPH,

2013).

•

Headaches & Migraine are leading cause of lost productivity,

accounting for 20.5 per cent of productivity losses according to Goetzel et al.

2004.

In one study the loss of productivity from migraine-related presenteeism was

measured as greater than the total cost of absenteeism (Burton et al. 2004).

•

Digestive Problems including chronic constipation and diarrhea, IBS,

over- and under-eating, indigestion, ulcers, and gas reflux can severely

reduce productivity through loss of energy, absenteeism and presenteeism.

Stress is a major driver of digestive problems. The significant reduction in

stress typical of InHappiness programs often results in dramatic reductions in

these problems as illustrated here.

Sleep Problems — Lack of sleep exacts a heavy toll on perception and

judgment. In the workplace, its effects can be seen in reduced efficiency

and productivity, errors, and accidents (Harvard).

Compared to healthy individuals, individuals suffering from sleep loss, sleep

disorders, or both are less productive, have an increased health care

utilization, and an increased likelihood of accidents (NIH).

Insomnia costs the average US worker 11.3 days, or $2,280 in lost

productivity every year (Kessler et al, 2011).

Almost 20% of all serious car crash injuries in the general population are

associated with driver sleepiness, independent of alcohol effects. Famous

workplace accidents caused by lack of sleep include  the tragedy at the

Bhopal, India, chemical plant; the nuclear reactor meltdowns at Three Mile

Island and Chernobyl; and the grounding of the Star Princess cruise ship and

the Exxon Valdez oil tankers (NIH).
