The Science

WHAT IS CIRCADIAN RHYTHM

Our body contains an internal clock that regulates alertness and sleepiness throughout the day. This biological timekeeper is called the circadian rhythm controls numerous physical and mental functions, including hormone production and energy levels. Modern lifestyle factors can disrupt this natural rhythm:
  • Reduced winter sunlight exposure
  • Excessive time spent indoors
  • Lack of natural light

Without proper sun exposure, the body's internal clock cannot properly calibrate itself and begins to drift away from its normal 24-hour cycle.

WHAT IS LIGHT THERAPY

Light therapy works by helping to reset and maintain our body's natural rhythms. As the primary external factor influencing our biological clock, light plays a crucial role in:
  • Regulating mood and energy levels
  • Controlling hormone production, including:
    • Melatonin (promotes sleepiness)
    • Cortisol (promotes alertness)
Our bodies are naturally programmed to synchronize with the sun's daily cycle. Light therapy lamps provide an effective indoor solution by:
  • Delivering bright light exposure
  • Using LED technology
  • Filtering out harmful UV rays

This therapeutic approach helps maintain proper circadian rhythm functioning when natural sunlight exposure is limited or disrupted.

HOW DOES CIRCADIAN OPTICS LAMP WORK?

Light is the biggest external factor that controls our body clock. It influences our mood and energy throughout the day. Human bodies are programmed to run in sync with the natural light of the sun. 

Our lamps mimic the color and brightness of the sun. Our lamps are an easy and effective way to get exposure to daylight indoors.

Light via eyes - When bright light enters the eyes, it stimulates specialized receptors cells that sets your body clock and regulates our sleep/wake cycle, energy and mood levels.

You don’t need to stare at the lamp, the light must reach your eyes to have any effect. This means you can use Circadian Optics while you’re working at the computer, watching TV, reading, etc. You should notice positive benefits after using Circadian Optics for a week.

WHEN SHOULD I USE MY LIGHT?

In the morning. Exposure to bright light in the early part of the day stimulates receptors in your eyes and sets your body clock for the day. Morning light is most effective in helping us be awake, alert and energetic during the day.

Our suggestion is setting up the lamp next to you at your work desk or breakfast table. Experiment with the light intensity and session duration until you find a routine that’s comfortable and effective for you. For most people, that’s 15 to 60 minutes a day, but your needs may be different.

HOW SHOULD I POSITION THE LAMP?

Position the lamp just off on the side of your face so that you aren’t looking directly into the light.

  1. Place the lamp on a stable surface, preferably a desk, 5”-18” away from your eyes. You can read, eat or work on your computer while you use the lamp. Good rule of thumb is setting the lamp next to your computer keyboard.
  2. Do not stare directly at the light. The lamp is effective even when the light reaches your eyes indirectly, from a sideways direction. Use the lamp in a well-lit room to minimize eye strain.
  3. Experiment with the light intensity and session duration until you find a routine that’s comfortable and effective for you. For most people, that’s 15 to 60 minutes a day, but your needs may be different.
