WHAT IS THE CIRCADIAN RHYTHM?

Often called the biological clock, the circadian rhythm is regulated by daylight, and plays an essential role in the balance of the human body.

The circadian rhythm sends signals to your body and regulates: heart rate, body temperature, blood pressure, hormone production, sleep, digestion, cognitive abilities, memory and mood.

​

Your health, your morale and your dynamism therefore depend essentially on your circadian rhythm: the amount of natural light you receive on a daily basis.

WHAT CAN AFFECT THE CIRCADIAN RHYTHM?

More and more scientific studies show that blue light (color temperature of more than 5000 K) present everywhere, in lighting (indoor and outdoor) as well as in all electronic devices, is very harmful for your circadian rhythm.

​

Being overexposed to blue light can throw your circadian rhythm out of whack and cause health issues like: 

​

• Mood disorders

• Drowsiness & sleep disturbances

• Metabolic & Cardiovascular Disorders

• Seasonal depression

• Obesity and diabetes

• Cancer

• Impairment of cognitive functions

HOW TO REGULATE THE CIRCADIAN RHYTHM?

CIRCAYA lamps have been created to combat this harmful blue light on a daily basis and to keep you healthier, all year round (and especially during winter).

​

CIRCAYA uses a new LED technology without blue light* ("blue light free") for its lamps. They are safe for your eyes (suitable for both adults and children).
