I nearly made a statement about candles, which I already make regular (but not yet consistent) use of at night. It's a difficult switch for many people to make because it requires regular material expense and forming new habits. I still encourage it, but I more strongly encourage people to spend time outside in the sun.

You can still get them, just look for 2500k, stay away from anything in the 4000k range and higher, they emit a lot of blues.
