Everything to Know About Your Circadian Rhythm

Updated: Aug 22, 2022

You may not realize it, but your body has a circadian rhythm – a shift in how your mind and body react to the world throughout the course of the day. And if you’re having trouble getting up in the morning or falling asleep at night, it might be because your circadian rhythm is out of sync!

What is our circadian rhythm?

Your circadian rhythm is the natural body clock that governs when you are awake and asleep. This internal 24-hour clock is based on the Earth’s cycle of day and night. It can be disrupted by jet lag, shift work, or other factors.

There are many benefits to having a healthy regulated circadian rhythm. According to research, people with a healthy circadian rhythm are more alert and productive during the morning hours. They also have fewer problems with sleepiness in the afternoon and evening.

If you’re looking to improve your health, it’s important to learn about your circadian rhythm and make adjustments as needed.

What does it do for us?

Our circadian rhythm is responsible for regulating our body’s sleep and wake cycles. This internal clock is based on sunlight and dark, which helps us to feel alert and energetic during the day and sleepy and lethargic at night. Our circadian rhythm also affects how we digest food depending on the time of the day (best before 5pm), how our immune system works, and how our hormones are produced.

What are the benefits of a regulated circadian rhythm?

Good energy levels and good sleep are the most obvious benefits, but also a regulated digestion, balanced blood sugar levels and hormones depend on a regulated circadian rhythm, as well as a reduced risk of heart disease and cancer.

How to maintain a healthy circadian rhythm?

There’s a lot of information out there on how to maintain a healthy circadian rhythm, but sometimes it can be difficult to know where to start. Here are some basics to help you get started.

UTC+00:00:00: This is the time zone in which most of us live. Most of our body’s cells are sensitive to daylight, so keeping your wake and sleep times in this zone will help you stay healthy and productive. The National Sleep Foundation recommends around seven hours of sleep for adults.

The sun-sleep connection: Our bodies are naturally wired to wake up and feel alert when the sun rises, because this is the time of day when most natural light reaches our eyes. When we’re awake during the day, our brains are processing all the new information we’ve gathered. Try to avoid working or spending time indoors during the late afternoon and early evening when the sun is setting, as this will disrupt your circadian rhythm.

Foods that affect your circadian rhythm: Eating foods that work with your circadian rhythm (instead of against it) will help keep your body on track. Avoid caffeine and sugary drinks before bedtime, eat


Understanding your circadian rhythm is key to optimizing your health and energy levels. By understanding when you are naturally energized and when you are naturally tired, you can better manage both your work and personal lives. Knowing when to sleep and when to eat can make all the difference in terms of feeling refreshed and energetic all day long. Visit wellness & health clinics in Dubai for the best advice on health.
