I agree with the other correction so I will just offer a different way of expressing the same idea to make it feel more natural.
Recently, I've had issues with waking up early, so I decided to research the topic to enhance the quality of my sleep. How my day starts is quite important to me. Firstly, what I find essential is considering the sleep cycles. The human sleep cycle lasts around 90 minutes, encompassing light sleep, deep sleep, and the rapid eye movement (REM) phase, during which we dream. Our bodies aren't designed to be interrupted during a sleep cycle. What I'd like to emphasize is that by tracking the time it takes you to fall asleep and adding your desired number of sleep cycles, you'll wake up feeling alert and refreshed. It's important to note that the number of sleep cycles needed varies from person to person, as does the amount of physical activity required by your body.
Secondly, to ensure uninterrupted sleep cycles, it's crucial not to be disturbed by anything unimportant while sleeping. If you live near a busy street, I'd recommend installing soundproof windows. Also, make sure to completely darken your room. Additionally, using earplugs may be beneficial.
In general, there are many ways to improve your sleep.
Hope this helps.
