I’ve got a flight to Paris, can I get those drops to prevent jet lag?
Not yet. But that hasn’t stopped the media from talking about it.
Here is the summary. Vasopressin plays a role in your circadian rhythm. A new study has shown that there is a subset of retinal ganglion cells (RGC’s) that express vasopressin and then project to the hypothalamus, the location of your biological clock. The theory is that tweaking the RGC’s to reduce the vasopressin signaling could help regulate your internal clock. Sounds cool but even the author said, “we are far from that at the moment”. (via)
