示范答案：
If I struggle to fall asleep at night, I have a few go-to habits that usually help—nothing too complicated, but they work for me.
First, I avoid screens entirely. Phones, laptops, or TVs emit blue light that tricks my brain into thinking it’s still daytime, which makes it harder to wind down. Instead, I’ll grab a physical book (something calm, not a thrilling novel) or listen to soft instrumental music or white noise—like rain sounds. These are low-stimulation and help my mind stop racing.
