Both the human and financial costs of stress are enormous. Statistics for workplace stress show that around 120,000 people die each year from work-related stress. The cost of stress in the workplace also drains the US budget, resulting in healthcare costs of around $190 billion per year. This represents between 5% and 8% of the total national healthcare spending.
