When I can’t sleep, I turn around and sleep “upside down” - moving my pillows to where my feet were beforehand, and my feet to where my head was beforehand - and I stick with that for a week or so. It gives me a week or so without insomnia and then wears off, so I have to turn myself back around for the next 7-12 day period.
Admittedly this could just be a me thing, but let’s put our faith in this method and let the power of placebo effect take hold. Boom, minor bouts of sleeplessness are cured.
What are your own examples of this?
Wait, are you saying you can look at a bright light to suppress a sneeze? I used to work with a guy who said bright light sometimes made him sneeze.
Looking at significantly bright lights cause the muscles of your face and sinuses to contract which can force a sneeze. It won’t cancel the sneeze, it just makes it happen on your own terms.
