1. Thought-Stopping Technique: We simply need to tell ourselves to stop so we can shift our attention away from whatever is preoccupying our thoughts. This works best if we have good control over our system. We can also try reverse psychology on ourselves. Many people do not realize it but worrying that we must sleep can actually stress us out and keep us from sleeping. What we need to do is to tell ourselves to stay awake for the longest time possible and before we know it, we might already be in dreamland.
2. Breathing Techniques: Which is as simple as breathing in and out deeply. And try to take long, deep breaths for a more relaxed feeling. Some people say this is quite an effective relaxation technique and this is something worth trying.
