Initiate a restart of the level after character death

So I currently have a character that switches to its ragdoll and “dies” upon contact with a kill object, however after the ragdoll falls out of screen I need the level to restart. I’m new to C#. Just looking for a simple way to get the game to restart without player input. I’m kind of moving over from java script so I don’t have reference for how to do this.

here is how I have the character death setup. any suggestions are greatly appreciated.

using UnityEngine;
using System.Collections;

public class Entity : MonoBehaviour {
	
	public float health;
	public GameObject ragdoll;

	
	public void TakeDamage(float dmg) {
		health -= dmg;
		
		if (health <= 0) {	
			Die();
		}
	}
	
	public void Die() {
		Ragdoll r = (Instantiate(ragdoll,transform.position,transform.rotation) as GameObject).GetComponent<Ragdoll>();
		r.CopyPose(transform);
		Destroy(this.gameObject);
		
	}
		
	}

Use the following code to restart the level:
using UnityEngine;
using System.Collections;

public class Entity : MonoBehaviour {
 
    public float health;
    public GameObject ragdoll;
 
 
    public void TakeDamage(float dmg) {
       health -= dmg;
 
       if (health <= 0) {    
         Die();
       }
    }
 
    public void Die() {
       Application.LoadLevel(Application.loadedLevel);
 
    }
 
    }

Appreciate all the feedback.It definitely helped. I got it all to work perfectly after reading more into the documentation of coroutines.

So I have tried all kinds of different values to get it to wait. I want it to wait for 5 seconds before restarting the level.

if (other.tag == "Player")
		{
			Instantiate(playerExplosion, other.transform.position, other.transform.rotation);

            

            if (time <= 6)
            {
                SceneManager.LoadScene(SceneManager.GetActiveScene().buildIndex);
            }

            time =   1;



        }
		
		gameController2.AddScore(scoreValue);
		Destroy (other.gameObject);
		Destroy (gameObject);
	}
}

I’ve tried changing the values to if (time >= 6) then if (time >= -6) I’ve tried the negative values on both the if factor and the time factor. Can you guys catch what I am doing wrong?
