> I use a full spectrum LED light most mornings for about 10-15 minutes while I catch up on email. It’s great—if you try nothing else in here, this is the thing I’d try.

It's 5500K and it says it mimics midday sun; I wonder if that could be harmful long term, as you're shocking your body awake - "it's midday, get up!" - rather than following a natural progression from dark to morning-light.
