Circadian Rhythm

Cirkadian Rytm – definition and facts in our glossary.

What is Circadian Rhythm?

This rhythm affects things like sleep, hormone production, metabolism, and gene expression.

How does it work in the body?

The circadian rhythm is controlled by a part of the brain called the suprachiasmatic nucleus (SCN), located in the hypothalamus.

  • Sleep cycles: The circadian rhythm influences our sleep cycles, making us feel tired at night and alert during the day.
  • Hormones: Many hormones in the body, including insulin and growth hormone, follow the circadian rhythm.

Scientific benefits

Several studies have shown that a well-functioning circadian rhythm is essential for our health:

Dosage and recommendations

Here are some tips:

  • Try to go to bed and wake up at the same time every day.
  • Avoid light from screens at least one hour before bedtime.
  • Expose yourself to natural light during the day, especially in the morning.

Best sources and forms

  • Omega-3 fatty acids: Have been shown to support brain function and may affect sleep.

Side effects and warnings

Although circadian rhythm is a natural process, disruptions can lead to negative effects. Here are some potential side effects of ignoring it:

  • Metabolic disturbances, including weight gain and insulin resistance.

Frequently asked questions

What are the most common causes of circadian rhythm disruptions?

The most common causes include irregular sleep habits, exposure to blue light in the evening, and shift work.

How can I improve my circadian rhythm?

Can supplements help regulate circadian rhythm?

Why is it important to maintain a stable circadian rhythm?

How does light affect our circadian rhythm?

Light affects our circadian rhythm by signalling to the brain when it is time to be awake or asleep. Exposure to light in the morning helps set our internal clock.
