ZNP,
My friend and I drove to a funeral together Memorial Day. As time went on, I noticed that my sinuses were closing. By an hour we pulled off and I had to walk to get my breath. I tried to figure out why I couldn't get enough O2. It wasn't simply allergies. I couldn't get enough air to compensate even when doing a hyperventilation technique. I discovered that I forgot to put my phone on airplane mode when we left my house. He had his on Google maps non stop and the phones were roaming on data. All that microwave radiation was messing up the oxygen carrying capacity of my body in a big way. I turned off mine and told him to do likewise. As time went by, I steadily improved. The symptoms disappeared so keep that in mind if you are tempted to leave your phone on while traveling or walking. It makes a big difference.
