The first is a good overview of sleep research in general, and specifically addresses some of the claims that are made about the purposes of sleep. Horne looks at several arguments (he agrees with some, and disagrees with others) but more importantly gives pointers to the research which supports or refutes each claim.

      The second is a book dealing with polyphasic sleep and chronobiology. Some of the findings presented there seem to have been missed by much of the sleep research community.

      Both books are fairly technical, but this is news for nerds, right?

      On a related note, sleep research is an area in which there are a lot of (widely) divergent views, all with some amount of data to back them up. Anyone who doesn't acknowledge this fact is not giving you the whole story. As a couple of examples, a number of hormones are released in different amounts thoughout the day (and night). In some cases, this is linked to sleep, but in others, the rhythm is linked to other zeitgebers without being directly related to sleep. Since most people sleep at night and are awake during the day, researchers have to be very careful to separate the two.

      Also, experimental methods can be very important. Some of the methods used to limit sleep (or one particular phase of sleep) have caused other trauma which may have been responsible for some of the results. And finally, much research has been done on rats or other small mammals, and then extrapolated to humans. The problem is that humans (unlike rats) have a big enough brain to relax without sleeping. Since the only way for a rat to relax is for it to sleep, there are a number of effects which are tied to being relaxed which some researchers have instead tied to being asleep. Horne's book covers all of these points in detail (as well as several others).

    One the things that those who practice ancient Chinese medicine believe is that certain types of energy run through meridians in the body, and are tied to individual organs or groups of organs. Supposedly, each energy has a peak time and a nadir time. For instance, the lung energy has its peak from 3-5 am and then the large intestine energy peaks from 5-7 am.

    Practitioners use this diagnostically by associating when people have a major dip in their energy level to show them which energy needs to be strengthened, which may indicate a pathology in that associated organ.

    The individual energies correlate to five elements that are each expressed by particular flavors, seasons, colors etc. and they will recommend a person increase their exposure to the things associated with the element where their energy is weakest.

    It would be interesting to see if the times of people's energetic nadir as predicted by this system or observed empirically did correlate to physical or emotional issues as predicted by this ancient system.
