It also shows why it is a good idea to sleep in a dark room, and
suggests that a good way of getting awake is to have a timer set to
brighten it (I use a 150W halogen lamp above my bed in the winters).

The use for jet-lag works (scientifically well studied and I have
personally tried it). The mental performance and longevity stuff is
unproven and rather controversial. The depression aspect is
interesting, but likely mediated through sleeping - SAD and some forms
of depression are influenced by when and how much you sleep.
