Wait in seconds before damaging the player again

Title says it all, basically I have a problem where my script damage the player in every second, I want to tell the script that it should be waiting like 5 seconds before damaging again.`{

public int Pain = 1;

void Start()
{

}

void OnTriggerStay (Collider other)
{
{

        if (other.gameObject.tag == "Player")

        {
            StartCoroutine(CountDown());

        Vector3 damageDirection = other.transform.position - transform.position;
            damageDirection = damageDirection.normalized;

            FindObjectOfType<PlayerHealth>().DamagePlayer(Pain, damageDirection);

        }
    }
}
IEnumerator CountDown()
{
    print(Time.time);
    yield return new WaitForSeconds(1000);
    print(Time.time);
}

}

I don’t think you need a Coroutine at all:

private float hitLast = 0;
private float hitDelay = 5;
void OnTriggerStay (Collider other)
{
    if (other.gameObject.tag == "Player")
    {
        if (Time.time - hitLast < hitDelay)
            return;

        Vector3 damageDirection = other.transform.position - transform.position;
        damageDirection = damageDirection.normalized;
        FindObjectOfType<PlayerHealth> ().DamagePlayer (Pain, damageDirection);

        hitLast = Time.time;
    }
}

put the damage function in coroutine too, or else they would execute together without delay. Something like this:
(Edit: if you want to use OnTriggerStay, you probably want to make sure you are not starting co-routine every frame when player is in trigger.)

 bool coroutineRunning;
 IEnumerator DmgAfterTime(float seconds)
 {
     coroutineRunning=true;
     yield return new WaitForSeconds(seconds);
     playerHealth.DamagePlayer (Pain, damageDirection);
     coroutineRunning=false;
 }

void OnTriggerStay(Collider other)
{
        //if not running
        if(!coroutineRunning)
        StartCoroutine(DmgAfterTime(5));

}

Another way to run function after time is to use delegate in a cotoutine.

public delegate void RunFuncDelegate();
public IEnumerator RunFuncAfterTime(RunFuncDelegate Func, float time)
{
    yield return new WaitForSecondsRealtime(time);
    Func();
}

This way you can call any function after a delay.

StartCoroutine(RunFuncAfterTime(() =>  playerHealth.DamagePlayer (Pain, damageDirection), 5));
