Time matters: How does circadian rhythm affect the performance and regeneration of the body and mind?

Every day, the body cycles through phases of activity and regeneration. The circadian rhythm, our natural biological clock that regulates physiological processes, influences not only sleep and wakefulness but also mental performance, immunity, metabolism, and longevity. When we live in harmony with this rhythm, our body can function more efficiently—potentially giving us more energy, better focus, a stronger immune system, and enhanced recovery. How does the circadian rhythm affect our daily performance, and why is it important to respect it?

The circadian rhythm is a natural 24-hour cycle that governs the function of our body and brain. It is influenced by:

  • light,
  • sleep,
  • diet,
  • physical activity,
  • and internal biological processes.

If this rhythm is disrupted—due to insomnia, poor diet, or an irregular lifestyle—it can lead to impaired focus, weakened immunity, slower metabolism, or faster cellular aging.

On the other hand, living in sync with the circadian rhythm allows the body to naturally adapt to different phases of the day, optimizing energy, immunity, and overall vitality.


Proper cognitive care can help maintain quality of life for a long time.

Upon Waking Up

There is a sharp rise in cortisol levels, helping the body transition from a resting to an active state. The brain prepares for work, and the body gears up for physical activity. At this stage, it is essential to:

  • Expose yourself to natural daylight, which synchronizes the internal clock.
  • Hydrate the body, as fluid loss occurs during sleep.
  • Kickstart metabolism with a breakfast rich in quality carbohydrates and proteins.

During this phase, it is beneficial to support mental performance with dietary supplements containing antioxidants and compounds that enhance brain circulation, such as ginkgo biloba or Baikal skullcap.

Before Bedtime

As late hours approach, cortisol levels naturally decrease, and the body prepares for regeneration. During this phase, it is crucial to:

  • Limit exposure to blue light (from mobile and computer screens), which can disrupt melatonin production.
  • Consume a dinner rich in proteins and healthy fats that support muscle and brain recovery.
  • Support the nervous system with B vitamins and antioxidants.

How Are Circadian Rhythm and Longevity Connected?

The circadian rhythm also influences long-term health and cellular regeneration. Studies suggest that people who follow a consistent sleep schedule and respect the body's natural phases may have a lower risk of neurodegenerative diseases and better metabolism.

Molecular hydrogen has the potential to support cellular protection and regeneration. Studies indicate that it may act as a selective antioxidant and influence cellular signaling, contributing to overall vitality.


Research suggests that Molecular Hydrogen® penetrates cells, aiding in repair and energization.
