That's because the body's internal clock is set for two 12-hour periods of light and darkness, and when this rhythm is thrown off, so is the immune system. One reason may be that the genes that set the body clock are intimately connected to certain immune cells, according to a new study. And that was what happened yesterday night, I was playing with my phone in the dark under the blanket. TOO MUCH LINK.
