What Is Circadian Rhythm & How Does it Relate To Better Sleep?

Sleep and wakefulness are controlled by your circadian rhythm. Most living things have a 24-hour body clock connected to this rhythm. Circadian rhythms are influenced by outside factors, such as light and darkness. Depending on your environment, your brain releases certain hormones, regulates your body temperature, and regulates your metabolism, keeping you awake or bringing you to sleep.

Sleep disorders or external factors can cause disruptions in the circadian rhythm of some individuals. The ability to respond effectively to your body’s natural rhythm depends on maintaining healthy habits, resulting in better sleep.

How Does The Circadian Rhythm Work?

Your body’s circadian rhythm is composed of several factors that interact with each other. 

Your body’s cells

First, your brain responds to light and darkness. Changes in the environment trigger your eyes to transmit signals to different cells about when it is time to go to sleep or wake up.

In response to this, the brain sends signals to other parts that activate other functions, making you feel fatigued or awake.

Hormones play an important role

Melatonin and cortisol are hormones that are affected by your circadian rhythm. The sleep hormone melatonin is released more in the evening and suppressed during the day. When you wake up, your body makes more cortisol, which boosts alertness.

Additional factors

Your circadian rhythm is also affected by your body temperature and metabolism. Your body temperature drops during sleep and rises during waking hours. You also have a different metabolic rate throughout the day.

Circadian rhythms can be influenced by other factors as well. Rhythms can change as a result of work hours, physical activity, and additional lifestyle choices or habits.

Circadian rhythms are also influenced by your age. Children, teens, and adults have different circadian rhythms.

When to Consult a Physician

If you are experiencing problems with your circadian rhythm, you may wish to consult a physician. Consider making an appointment with your doctor if you experience any of these symptoms for a prolonged period:

  • Having difficulty getting adequate sleep every night
  • Having difficulty falling asleep
  • Awaken several times during the night and are unable to get adequate sleep
  • Having difficulty waking up
  • Feel extremely fatigued during waking hours

Sleep loss is a major contributing factor to many road and workplace accidents. You could also experience impaired cognitive functions and, over time, become more susceptible to serious health problems, such as heart attack and high blood pressure.
