How to check if there is a ceiling above the player?

I added crouching to my movement script, what messing is to check if there is a ceiling above the player, and if there is the player should remain crouched. How would I achieve this?

currently, for crouching, the user should press the c key and if he wants to stand up, he should press it again.

enter image description here

UPDATED CODE:

if (crouching)
        {
            isRunning = false;
            transform.localScale = new Vector3(transform.localScale.x, crouchYScale, transform.localScale.z);
            movement = (move.y * transform.forward) + (move.x * transform.right);
            controller.Move(movement * crouchSpeed * Time.deltaTime);
        }
        else
        {
            
            transform.localScale = new Vector3(transform.localScale.x, startYScale, transform.localScale.z);
            movement = (move.y * transform.forward) + (move.x * transform.right);
            controller.Move(movement * moveSpeed * Time.deltaTime);
        }

 controls.Player.Crouch.performed += _ => OnCrouch();

Here is my attempt:

public void OnCrouch()
    {

        RaycastHit hit;

       bool checkCeiling =  Physics.Raycast(transform.position, -Vector3.up, out hit, 2f);
        if (crouching && checkCeiling == true)
        {
            crouching = false;
        }
        else
        {
            crouching = true;
        }
    }

But this does not show any result. the Player still can stand up even if there is a near ceiling above his head. How can I prevent standing up if there is a near ceiling and allow it only when there is enough space to stand up? please help.

Most game logic allows to uncrouch only if there is no ceiling above the player, but does not auto-crouch upon approaching low-ceiling areas. In your toggle function, do the ray cast like this:

public void OnCrawl()
{
  if(crouching && Physics2D.Raycast(transform.position, Vector2.up, 2f).collider == null) 
    crouching = false;
  else 
    crouching = true;
}

Keep the rest of your code as is and you should be good to go.
