Why can't I convince myself that it is important for me to sleep?

It can be hard to, sleep is important for the body so your body will give you signs at some point and without sleep your body may start to suffer

While I can’t know exactly why convincing yourself about why you should sleep is a challenge, one possible reason is that you may not understand why it is so incredibly important to your overall health. Sleep helps your memory, learning ability, response time and concentration levels. Research shows that sleep reduces your risk for certain health conditions by improving your immune system. There is a certain phase during the sleep cycle where your body is completely relaxed. Without that cycle, it’s hard to feel refreshed and relaxed upon waking. There are so many other reasons why working toward a regular sleep schedule is a healthy habit. I encourage you to read more about this by searching the internet for “benefits of sleep” and I believe you will convince yourself.
