Ruby Thread not sleeping but finished

Question

I have coded something in ruby. Now, I want to make it so that every 3 seconds that code runs again. I have looked at threading. I built a thread and I put a

while true do end

loop inside it. Also I make it sleep for 3 seconds. Take a look

Thread.new do 
while true do
#code 
end
sleep 3
end

My problem is that when I run my code it doesn't run it at all and it doesn't repeat. Thank you

Here's how to do it:

Thread.new do
  loop do 
    sleep 3000
    # your code here
  end
end
