Every single person is born with an internal clock, and this is an extremely helpful tool that you need to use on a regular basis. Your internal clock is made up of nerve cells in the brain, and it controls your alertness and sleepiness throughout the day, your hunger, and your blood pressure.
Your body runs on its own clock.
Your internal clock works on a 24-hour cycle, and this cycle is determined by the lightness and darkness of your day. However, once your body has become accustomed to your clock, it doesn’t need the light and dark to determine your feelings. For example, if you’re stuck in a windowless building all day, your body will still work on its pre-existing 24-hour clock, which will keep your alertness/sleepiness and everything else on track.
Clocks vary from person to person.
Your internal clock may be scheduled on a 24-hour cycle like everyone else, but each individual has their own unique clock that determines their body’s functions. For example, your internal clock is what determines if you’re a morning person, an afternoon person, or a night person. Listening to this internal clock is important to help you learn how to best organize your day. For example, if you’re a student and your body gives you the most energy late at night, it would be best to schedule your study and homework hours during the night. This will ensure that you’re giving the proper amount of attention to the things that are important.
Your internal clock helps you sleep.
Getting the right amount of sleep is important. Sleeping helps to re-energize your body and gives your body a slight break from your daily activities. Your internal clock will help determine when you’re tired, and you need to listen to this to ensure that you get the right amount of sleep. For example, staying awake well after your body is telling you that you’re tired can result in poor decision making or falling asleep at the wrong time, such as when operating a vehicle. When your body tells you that it’s tired, it’s letting you know that every part of your body needs a break in order for you to function properly.
Sometimes your body will tell you that it’s tired when you’re typically awake. This is not your internal clock malfunctioning—it’s simply letting you know that you need a break. If you’re at work, it may be hard for you to get in a nap, but you can try to take a small break and rest your body and mind for a few minutes to re-energize.
If you’re able to take a nap, allow yourself to fall asleep to help your body rest. If you try to nap and simply can’t fall asleep, reading a book or even watching television can be the right break your body needs.
Your internal clock determines your alertness throughout the day, and this is important for your optimal functionality. Listening to your internal clock is important to ensure that you get the right amount of rest to keep your body and mind in great shape.
