How To Save Health Between Scenes

Hello.

I'm making a 2D videogame in Unity 2020.3.11f1 for a project for my high school. This is the second time I use C# scripting through Visual Studio, and I'm still not acquainted with some terms. The thing is I have an entire script for the main character of my videogame with its movement, attack, knockback... I also have its health programmed in there. The thing is it works perfectly, the health decreases when it has to. But the problem I have is that when the character goes to another scene, the health goes back to its maximum value and I don't want that, because it looks awkward. The health it's made through a scriptable object called Float Value. And it's a heart system, not a health bar system. Since, as I previously said, I'm still not so acquainted with Unity programming and C#, I'm watching tutorials to complete the game, from the series "Make a game like Legend of Zelda using Unity and C#" by Mister Taft Creates, if you want to take a look (more or less, from part 23 to 25). Here's the codes:

Player Code

 using System.Collections;
 using System.Collections.Generic;
 using UnityEngine;
 
 public enum PlayerState
 {
     walk,
     attack,
     interact,
     stagger,
     idle
 }
 
 public class PlayerMovement : MonoBehaviour
 {
     public PlayerState currentState;
     public float speed;
     private Rigidbody2D myRigidbody;
     private Vector3 change;
     private Animator animator;
     public FloatValue currentHealth;
     public SignalGame playerHealthSignal;
 
 
     // Start is called before the first frame update
     void Start()
     {
         currentState = PlayerState.walk;
         animator = GetComponent<Animator>();
         myRigidbody = GetComponent<Rigidbody2D>();
         animator.SetFloat("moveX", 0);
         animator.SetFloat("moveY", -1);
     }
 
     // Update is called once per frame
     void Update()
     {
         change = Vector3.zero;
         change.x = Input.GetAxisRaw("Horizontal");
         change.y = Input.GetAxisRaw("Vertical");
         if(Input.GetButtonDown("attack") && currentState != PlayerState.attack && currentState != PlayerState.stagger)
         {
             StartCoroutine(AttackCo());
         }
         else if (currentState == PlayerState.walk || currentState == PlayerState.idle)
         {
             UpdateAnimationAndMove();
         }
 
     }
 
     private IEnumerator AttackCo() 
     {
         animator.SetBool("attacking", true);
         currentState = PlayerState.attack;
         yield return null;
         animator.SetBool("attacking", false);
         yield return new WaitForSeconds(.3f);
         currentState = PlayerState.walk;
     }
 
     void UpdateAnimationAndMove() 
     {
         if (change != Vector3.zero)
         {
             MoveCharacter();
             animator.SetFloat("moveX", change.x);
             animator.SetFloat("moveY", change.y);
             animator.SetBool("moving", true);
         }
 
         else
         {
             animator.SetBool("moving", false);
         }
     }
 
     void MoveCharacter()
     {
         change.Normalize();
         myRigidbody.MovePosition(
             transform.position + change * speed * Time.fixedDeltaTime
             );
     }
 
     public void Knock(float knockTime, float damage)
     {
         currentHealth.RuntimeValue -= damage;
         playerHealthSignal.Raise();
         if (currentHealth.RuntimeValue > 0)
         {
             StartCoroutine(KnockCo(knockTime));
         }
 
         else
         {
             this.gameObject.SetActive(false);
 
         }
         
     }
 
     private IEnumerator KnockCo(float knockTime)
     {
         if (myRigidbody != null)
         {
             yield return new WaitForSeconds(knockTime);
             myRigidbody.velocity = Vector2.zero;
             currentState = PlayerState.idle;
             myRigidbody.velocity = Vector2.zero;
         }
     }
 }

where Float Value comes from:

 using System.Collections;
 using System.Collections.Generic;
 using UnityEngine;
 
 [CreateAssetMenu]
 public class FloatValue : ScriptableObject, ISerializationCallbackReceiver
 {
 
     public float initialValue;
 
     [HideInInspector]
     public float RuntimeValue;
     public void OnAfterDeserialize()
     {
         RuntimeValue = initialValue;
     
     }
     public void OnBeforeSerialize(){}
 
 }

If someone knows how to save the health between scenes with these type of scripts I would be really grateful and it would be a lot of help for my project.

Thank you.
