Why Jerks at Work Are Making You Sick—And What Science Says to Do About It

The Hidden Health Costs of Toxic Colleagues (And How to Heal)

Think a toxic coworker is just an annoyance? Think again. According to Tessa West and leading workplace psychologists, chronic exposure to jerks at work can literally make you sick. Victims report insomnia, headaches, high blood pressure, and even hair loss—symptoms you’d expect in much older adults. The stress isn’t just emotional; it’s deeply physical.

Worse, stress spreads like wildfire. One anxious team member can infect an entire group, tanking morale and productivity. Avoidance seems like a solution, but it rarely brings lasting relief. Instead, it breeds isolation and even greater anxiety.

Science-backed recovery starts with connection. Build a wide network of allies, not just close friends. Document every toxic incident—specifics matter more than emotion when seeking help. Practice self-care: sleep, nutrition, and even simple gratitude rituals can help reverse the damage. And remember, optimism is contagious too. Teams that celebrate small wins and support each other can transform even the most toxic culture. 1 3
