Life Time: The New Science of the Body Clock, and How It Can Revolutionize Your Sleep and Health

In 1991, Foster and his colleagues provided evidence that rods and cones are not necessary for entrainment of an animal to light. [11] In this experiment, Foster gave light pulses to retinally degenerative mice. These mice were homozygous for the rd allele and were shown to have no rods in their retina. Only a few cones were found to remain in the retina. To study the effects of light entrainment, magnitude of phase shift of locomotor activity was measured. The results showed that both mice with normal retina and mice with degenerate retina showed similar entrainment patterns. Foster hypothesized that circadian photoreception occurs with a small number of cones without an outer layer or that an unrecognised class of photoreceptive cells are present. Russell Foster is perhaps best known for his team's contribution to the discovery in the late 1990s of photosensitive retinal ganglion cells, a type of neuron in the eye. Unlike the eye's rod and cone cells, they're not responsible for forming images, but for detecting light, providing information to the brain about the length of day and length of night. The ground-breaking discovery of these cells and their function was a milestone in the now exploding field of circadian biology to which Russell has dedicated his working life.

Social jet lag, a term developed by Till Roenneberg, is what people suffer if they are either living on a Western edge of a time-zone (book doesn't explain what location that is), or from Daylight Savings hours (created by Germans originally to ration coal), or due to social/work demands we sleep irregular hours.

We now appreciate that every aspect of the immune response is being regulated by the circadian system. The skin is one of the most important, but most overlooked, parts of our immune defence... providing an effective barrier. the extraordinary effects the time we take our medication can have on our risk of life-threatening conditions, such as strokes sleep loss is associated with increased release of the 'hunger hormone' ghrelin from the stomach and reduced release of the 'satiation hormone' leptin from adipose tissue."

Easy to read and understandable for most of it but some parts do get more scientific and the reading becomes difficult. I think it was an audience that is too wide, it aims to be a book for non scientific audience but at the same time includes parts for a scientific audience and the mix is not great. The male praying mentis has his head eaten while mating (doesn't stop the act) and then the female eats the rest of him. Poor sod. Foster, R.
