how do you use Debounce I want to use it on my healing script ?

I know what is Debounce but I don't want to use it I want the script to not repeat itself too fast

function Touched(hit) if hit.Parent:FindFirstChild("Humanoid") then hit.Parent.Humanoid.Health = hit.Parent.Humanoid.Health + 5 end end

script.Parent.Touched:connect(Touched)
