Night-night

Sleep is easy for some and like the holy grail for others, and we need it more than you may think. In fact, a new study published in the Journal of Experimental Medicine suggests that the health of our immune systems actually might depend on it. It’s all about T cells, which help battle viruses and cancer cells, and little adhesion molecules called “integrins.” Researchers in Germany have found that, in order for T cells to do their work, they have to stick to all the bad stuff. However, certain stress hormones prevent that necessary bond. These stress hormones get sleepy when you sleep, though, so that is when T cells have the most power to battle all the nasty stuff and muscle-up your immunity. Lesson for the day: If you want to stave off that cold and prevent infection, find a good pillow and turn off the lights.
