Many people suddenly feel the urge to sneeze when they look into bright light. This is known as the “photic sneeze reflex” or ACHOO syndrome (Autosomal Dominant Compelling Helio-Ophthalmic Outburst) and is quite common. Studies estimate that it affects approximately 18–35% of the population.
The exact cause remains unclear to this day, and with 5BN knowledge, further considerations can be made in this regard. According to this theory, the bright light could represent a « track, » meaning that those affected may have experienced a severe weather-related conflict involving the ectodermal nasal mucosa when they were suddenly exposed to brighter light.
Both Thorsten Rüffer from my study group and I independently had the same thought about this:
Could this cluster be due to the fact that, at birth, we are suddenly brought from the near-total darkness and security of the womb into more or less harsh light? And sometimes under quite dramatic circumstances? In a hospital, bright lights and a dramatic atmosphere are certainly much more likely than in birthing centers or during home births, where the focus is usually on dim lighting (as well as calm and relaxation).
For me personally, it would definitely work (I have the reflex, and I had a C-section).
