There are stairs near the building where I live and there is a palm tree next to them - it has giant green leaves that are just above those stairs. These leaves have quite sharp edges as well.

Sometimes when I climb up these stairs, I accidentally smash my head against some of the leaves when I jump up to the next stair (the leaves are hanging low above the stairs and I sometimes jump and by accident get hit on the head with their edges).

It hurts in the head when it happens, and it has already happened a few times, so I'm slightly concerned about this.

Is it OK that when I jump up the stairs I sometimes hit my head against the leaves that above the stairs? The leaves are giant and have sharp edges (which are not soft), so I'm wondering if it might be dangerous and possibly worsen my brain injury.

In case you've never seen these leaves, this is how they look like:



So is it OK, or it could be dangerous and make my head injury worse?
