When I try to take health away from the player in unity using this code, it just says as an error playerhealth.takedamage() is inaccessible due to its protection level, fix?

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class EnemyShoot : MonoBehaviour
{
   
   public Transform rifle;
   public Transform player;
   public float distance; 
   
    // Start is called before the first frame update
    void Start()
    {
        
    }

    // Update is called once per frame
    void Update()
    {
        transform.LookAt(player);
    }

    private void Shoot()
    {
        RaycastHit hit;

        PlayerHealth playerHealth;

        if(Physics.Raycast(transform.position, transform.forward, out hit, distance))
        {
            if(hit.transform.tag == "Player")
            {
                playerHealth = hit.transform.GetComponent<PlayerHealth>();
                playerHealth.TakeDamage();
                Debug.Log(playerHealth.health);
            }
        }
    }
}
