Our eye movement stops and body temperature also drops. This stage also marked by some brief bursts of electrical bursts. Generally we spend most of our repeated sleep cycles in this stage.
Third stage- It's a period of deep sleep and we need it most to feel refreshed in morning. It lasts during the first half of night. In this stage, our heart rate and breathing slows to its lowest level. In this stage it is difficult to awake you. In this stages brain waves become even slower.
