Grief is a natural response to loss, deeply rooted in our biology and psychology. When we lose someone or something important to us, our brains and bodies react in ways that can be quite intense and overwhelming.
At its core, grief is about the attachment we have to what we’ve lost. Our brains form strong connections with people, places and things that bring us joy and comfort. When these connections are broken, our brains struggle to adjust to the new reality, leading to feelings of sadness, confusion and even physical pain.
For example, think about a time when you lost something precious, like a cherished pet or a close friend moved away. The sadness you felt wasn’t just in your mind, it was a whole-body experience. This is because grief activates the same areas of the brain that process physical pain. It’s why heartbreak can feel like a real, physical ache in your chest.
Our bodies also react to grief by releasing stress hormones like cortisol. This can lead to symptoms like fatigue, trouble sleeping and changes in appetite. It’s our body’s way of telling us that something significant has happened, and we need time to heal.
Grief also serves a purpose in helping us process and come to terms with our loss. It gives us the space to reflect on what we’ve lost and find ways to move forward. Over time, the intense feelings usually lessen, and we find new ways to carry the memory of what we’ve lost while continuing with our lives.
