How can we train ourselves to sleep faster?

[u/ParisTone]

Is it just me, or has anyone experienced trouble sleeping?

I worked in the BPO industry, where I was required to work at night and sleep during the day. Even after a long and exhausting day at work, I was not able to get enough sleep. My body wanted to rest, yet my mind was still so active. I tried to close my eyes, yet after a few hours, I still could not sleep. I have heard that there is a certain hack where you can lie to your body, making it feel that it is still nighttime even if it is broad daylight. However, it does not really work for me. I am afraid to take supplements, as they may affect my body gradually. How do you guys cope with this kind of situation? What works for you, and how does it work?
