My blood oxygen level is between 90% and 92% and it regularly drops below 88% when I have an infection. Physical exertion such as walking up and down stairs or slight inclines on a road can only be managed with several stops in between. Every cold or cough develops into a major infection, which in most cases can only be brought under control by hospitalisation.

In October 2023, I had another one of those colds that wouldn’t go away despite two courses of antibiotics. I met Mr Peter Schnorr, my new neighbour, as I was walking from the car park to our flat. The path is only 50 metres long with a slight incline and I still had to stop several times to catch my breath.

He recommended this light therapy, which I then did 6 times for half an hour over 2 weeks. After 2 weeks, my blood oxygen level increased to between 95% and 97% and when I climbed a steep flight of stairs for the first time, I only realised at the top that it had gone without a hitch.

My enthusiasm knows no bounds and I first have to be able to grasp and realise my newfound quality of life. Best neighbour ever!!!! I am eternally grateful!
