Blue Light Therapy

Blue light therapy is a prototype of simpler apps that I will be building in the future.

Blue Light Therapy iPhone App

Blue Light Therapy is a prototype app. It allows you to play with blue light to activate suprachiasmatic nucleus SCN within your  brain. It is one of the few brain regions that receives input directly from the eye. Whether SCN is sensitive enough to iPhone screen light is unknown. Whether it works or not will be determined based on the user feedback. Until then it will stay as a free app that you can try to lift your mood or awaken your brain.

How to use the app

Simply set the timer to 3-10 minutes and star the app. The app will play music and animate ripples on a blue background. You can create your own ripples by moving your finger along the screen. Observe the ripples consciously and wait for the app to hide the screen. When the screen is hidden, you know that your session is complete.

By keeping consistent length sessions at consistent times of the day, you may help entrain your brain to a different daylight cycle length. This may sound like an odd thing to do, but for so many people whose lives are spent in pastel colored cubicles under dim artificial fluorescent light, the lack of blue light exposure may be quite a real threat, especially when the winter comes and it’s”Get up its dark, leave work, it’s dark”, and there’s no time to get exposure to open sky and sunlight.

This app has not been extensively tested. It does not offer to treat, cure or diagnose any medical conditions. I’m offering it here as a free tool that I developed for personal use and hope that it may be beneficial to a small fraction of the general population.

If you experience discomfort after using the app, I would recommend discontinuing the use of the app.

As a reminder, always consult your healthcare practitioner before doing anything that may affect your circadian rhythms. Do not use this app in the later part of the day, before sleep or in the middle of the night. Doing so poses real dangers to your circadian rhythm, and thus your overall wellbeing.

Touching the screen creates ripples that bounce off the walls, producing all possible shades of blue!
