How to save life counter when changing scenes in unity

Question

so i created life system, whenever player dies it substracts one life and when there is no more life left it takes player to game over screen, however when player goes from one scene to another life counter resets, is there any easy way to fix this? im new to programming so its hard for me to understand complexed solutions. Here is the code

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

public class GameControlScript : MonoBehaviour
{

    public GameObject heart1, heart2, heart3, heart4;
    public static int health;
  
    void Start()
    {
        health = 4;
        heart1.gameObject.SetActive (true);
        heart2.gameObject.SetActive(true);
        heart3.gameObject.SetActive(true);
        heart4.gameObject.SetActive(true);
        
    }


    void Update()
    {
        if (health > 4)
            health = 4;

        switch (health) {
            case 4:
                heart1.gameObject.SetActive(true);
                heart2.gameObject.SetActive(true);
                heart3.gameObject.SetActive(true);
                heart4.gameObject.SetActive(true);
              break;

            case 3:
                heart1.gameObject.SetActive(true);
                heart2.gameObject.SetActive(true);
                heart3.gameObject.SetActive(true);
                heart4.gameObject.SetActive(false);
              break;

            case 2:
                heart1.gameObject.SetActive(true);
                heart2.gameObject.SetActive(true);
                heart3.gameObject.SetActive(false);
                heart4.gameObject.SetActive(false);
              break;

            case 1:
                heart1.gameObject.SetActive(true);
                heart2.gameObject.SetActive(false);
                heart3.gameObject.SetActive(false);
                heart4.gameObject.SetActive(false);
              break;

            case 0:
                heart1.gameObject.SetActive(false);
                heart2.gameObject.SetActive(false);
                heart3.gameObject.SetActive(false);
                heart4.gameObject.SetActive(false);
                SceneManager.LoadScene(3); 
              break;

        }
    }
}
