This lecture from Alexander Wunsch was presented at the 84th International Conference on Light and Vision of the College of Syntonic Optometry (CSO) in Indianapolis, IN, USA.
In photobiology, the definition of action spectra is a crucial step in understanding the underlying mechanisms. Once the action spectrum is found, it often serves as a guide for phototherapeutic interventions, aiming to match the wavelength as closely as possible. Lasers and LED light sources are on the rise and widely available. Monochromatic light is highly effective – but mother nature´s light sources are differently composed. The presentation discusses the value of diligently combined wavelengths even from opposite regions of the light spectrum for phototherapy, photoprevention and cosmetic use.
Remarks: Some of the topics have been addressed in other presentations provided on my vimeo account. Anyhow, repetitions can help to make things clearer. Or, in Latin words: repetitio est mater studiorum…

Wie Licht den BMI beeinflusst: Wer früher sonnt, ist eher schlank – Video – Video – FOCUS Online.

Licht übt auf eine Reihe von Stoffwechselfunktionen einen nachhaltigen Einfluss aus. Dieser Beitrag beschreibt Zusammenhänge zwischen Zeitpunkt der Sonnenexposition und dem BMI.

“Our biological clocks measure the day length and change our behavior according to the seasons. We were curious to see if light signals could shape the development of the biological clock,” said McMahon.

The human body literally glimmers. The intensity of the light emitted by the body is 1000 times lower than the sensitivity of our naked eyes. Ultraweak photon emission is known as the energy released as light through the changes in energy metabolism. We successfully imaged the diurnal change of this ultraweak photon emission with an improved highly sensitive imaging system using cryogenic charge-coupled device (CCD) camera. We found that the human body directly and rhythmically emits light. The diurnal changes in photon emission might be linked to changes in energy metabolism.
