Health Bar decreasing way too fast.

I created the game objects Player and Spikes in my game, along with other objects. I attached a health bar to the Player(also with sound) and upon colliding with the Spikes, the bar decreases which it normally has to. But the problem is that it is decreasing fast. I saw the Player Health example in the Helpful Examples under Resources, so how come the health bar there is decreasing slow?
Even in the Flowlab! Part 6 under the Video Tutorials, the health number decreases slow even when the Player is standing on the Spikes. How do you do that?

You have to post examples of what you’re doing to get any real help, but look at repeat delay setting for collision behavior

So do you mean to say that I should post my game?

Thanks I got it.
