Similarly, people sometimes feel like they have built-up stress, frustration, or anger that they need to release before it becomes overwhelming.
So, when someone says they need to “blow off steam,” it’s like saying they need to let go of those negative feelings or excess energy. This can be achieved through various activities like exercising, talking to a friend, listening to music, or even just taking a break to relax and unwind. It's a way to manage emotions and prevent them from causing harm or stress. It’s essential to find healthy ways to blow off steam because keeping everything bottled up inside can be detrimental to mental and emotional well-being.
