In one sentence, describe what the following article is about: Nerves in your brain control your body’s clock, known as your circadian rhythm.

So the best way to adjust your sleep cycle is to be consistent and make it a routine.  Take care not to deprive yourself of sleep. There are many studies about the dangers of sleep deprivation so talk to your medical professional before attempting to change your sleep schedule for a long period of time.  More sleep isn't always healthier than less sleep. Scientists don’t know whether sleeping longer is a symptom of poor health or the cause of it. Consult your health professional to see if there is a deeper concern as to why you are staying in bed longer such as sleep apnea or depression. If you stay up later than normal because you don’t feel tired, don’t force yourself to sleep but rather let your body adjust naturally. Eventually, you'll be tired earlier and will be able to easily fall asleep at an earlier time. Your body will naturally regulate your sleep schedule. Don’t feel frustrated if you can’t fall asleep because you might develop insomnia from becoming anxious at the thought of not being able to fall asleep. Trust that your new cycle with set itself. Each of us have different capacities at which we can function with little to no sleep. Some of us can be fully alert with just 4 hours of sleep while others need more than 8.  Calculate how much time you will need to get enough sleep to perform the task you want and set your night’s schedule accordingly. For example, if you want to wake up to catch a meteor shower at 3am and know you are able to function with only 4 hours of sleep, get into bed around 10:30pm. If you're just waking up in the middle of the night for a specific one-time event, planning exactly when you should go to bed is smart. But if you're trying to adjust your sleep cycle for a longer period of time, let your new cycle come naturally, and don't try to force it.

Practice by waking up at the same time for a month. Sleep when you’re tired and wake up at the same time every day. Plan your night’s schedule.
