create a respawn after character die

hi guys ! i need some help on how to create a respawn after the character die. So i already create a health script, i just want when the health = 0 then the character will die and you need to wait 5 second then respawn back to a way point that i created at empty object. here is health script: public class playerHealth : MonoBehaviour {

     public int HeroMaxHealth;
     public int currentHealth;
     
     public float flashSpeed = 5f;
     public Color flashColor = new Color(1f, 0f, 0f, 0.1f);
     public float timer;
     public float BloodGenerateTime ;
 
     public Text HealthText;
     public Slider healthSlider;
     public Image damageImage;
     Animator anim;
     player playerMovement;
     public bool isDead;
     bool damaged;
     // Use this for initialization
     void Awake () {
 
         //Setting up the references.
         anim = GetComponent<Animator>();
         playerMovement = GetComponent<player>();
         healthSlider.maxValue = HeroMaxHealth;
         healthSlider.value = HeroMaxHealth;
         currentHealth = HeroMaxHealth;
        
 
 
     }
     
     // Update is called once per frame
     void Update () {
         //If the player has just been damagedd....
         GetHealthText();
         timer += Time.deltaTime;
         if(damaged)
         {
             // set the colour of the damageImage to the flash colour
             damageImage.color = flashColor;
         }
         else
         {
             // transition the color back to clear.
             damageImage.color = Color.Lerp(damageImage.color, Color.clear, flashSpeed * Time.deltaTime);
         }
         damaged = false;
 
         HealthGenerate();
 
 
     }
 
     public void TakeDamge(int amount)
     {
         //Set the damaged flag so the screen will flash.
         damaged = true;
 
         //Reduce the current health by the damage amount.
         currentHealth -= amount;
 
         //Set the health bar's value to the current health.
         healthSlider.value = currentHealth;
 
         //If the player has lost all it's health and the death flag hasn't been set yet...
         if (currentHealth <= 0 && !isDead)
         {
             Death();
         }
 
     }
 
     void Death()
     {
         //Set the death flag so this function won't be called again.
         isDead = true;
 
         //Tell the animator that the player is dead play die clip
         anim.SetTrigger("Die");
 
         //Turn off the movement 
         playerMovement.enabled = false;
 
     }
 
     void HealthGenerate()
     {
         if (currentHealth < HeroMaxHealth && !isDead && timer >= BloodGenerateTime)
         {
             currentHealth += 1;
             healthSlider.value = currentHealth;
             timer = 0;
         }
     }
 
     void GetHealthText()
     {
         HealthText.text = currentHealth.ToString() + "/"  + HeroMaxHealth.ToString(); 
     }
 }
