Compartmentalization is not inherently “good” or “bad.” Like many psychological processes and practices, it all depends on why and how you’re using it.
Sheridan says compartmentalization can be a healthy practice when used appropriately because it can help isolate issues that could be overwhelming if considered as a whole.
When used in a beneficial way, compartmentalization can help you set aside stressful thoughts and emotions, regulate your emotions, efficiently problem-solve, enhance attention and focus, and maintain boundaries.
“…[compartmentalization] becomes unhealthy,” Sheridan explains, “when it leads to denial or persistent avoidance of significant emotional or existential issues. If compartmentalization is used to ignore or avoid emotions or problems, it can lead to increased psychological distress or a break-down in emotional processing.”
He adds that it’s not just about dividing life into manageable parts. It's also about understanding and accepting that not every aspect of life can be controlled or resolved immediately.
It’s this acceptance that allows you to focus on what can be managed in the present, leading to more effective handling of stress, challenges, and adversity.
