I've talked to various health care professionals and one of the consistent features is the need to manage stress associated with death.
From the high-intensity environments of trauma centers to the comparably quieter, lingering death of hospice care, and gradual deterioration of a loved one's body at home, the stresses of healthcare provides are multifaceted. Too often, the healthcare system doesn't provide sufficient care for the those caring for the dying and dead.
Healthcare providers react to death differently. Some work out, others meditate. Some develop more empathy, others disengage in order to preserve their sanity. But it's an uphill battle because of the intimacy of death, especially for healthcare providers who experience in a uniquely direct way.
