In Greek mythology, Hypnos is the God of Sleep. He is the son of Nyx (night) and Erebus (darkness) and his twin brother is Thanatos (death). They live in the underworld (Hades). So even in ancient time sleep has been linked to darkness, death and hell. Foster is not a clinician. This is quite clear. He has this bizarre, amusing, and frankly insulting idea that doctors are completely formed after medical school. He implies on a number of occasions that your GP or hospital clinician could not have the foggiest clue about sleep science because it is not an integral part of the medical school curriculum. Give me a break. As if, after the age of 22 the medical brain is impermeable to all other information. Doctors couldn't possibly begin to advise pharmaceutical companies because God-forbid they ever attempt to read a paper that wasn't explained to them in second-year physiology. It's laughable. Medical school is, in actuality, like a preparatory pre-school for the school of intensive medical formation that continues up until, well, a doctor's... death.

As easy as the book is to read, or listen to, there is a sense that some material here is designed to signpost for undergraduate students areas they might take their future studies. History books do this all the time, and it is fun to see it in the context of biology. Foster has a great deal of wit in his writing, and the cadence with which he delivers his own narration is frankly superb. Around chapter 10, the focus of the book begins to narrow in on specific subjects, and it is here where many more casual readers may begin to find their interest slipping. Drugs, food, exercise and current academia are all areas people would likely want to know more of, but for some reason the subject matter landed a lot less smoothly in these chapters than earlier entries. Benzodiazepines, which was discovered accidentally by Leo Sternbach in 1955 who worked for Hoffmann–La Roche after escaping the Nazis. The first was chlordiazepoxide (Librium)), then diazepam (Valium).

And then there's the bit where he bangs on about how nocturia can keep you up at night (terrible), and then advises his previously maladvised clinician colleagues to prescribe all of their patients their DIURETICS before bed.)

Foster attended Heron Wood School in his native Aldershot and studied at the University of Bristol and graduated with a Bachelor of Science (BSc) in Zoology in 1980. He also carried out postgraduate studies at the University of Bristol under the supervision of Brian Follett, and was awarded a PhD in 1984 for his thesis entitled An investigation of the extraretinal photoreceptors mediating photoperiodic induction in the Japanese quail (Coturnix coturnix japonica).

All of these drugs work to enhance GABA release (the neurotransmitter gamma-aminobutyric acid), but have long-term use problems. People are instead encouraged to try CBTi: cognitive behavioural therapy for insomnia Weight Gain & Obesity: high levels of cortisol (stress hormone) can lead to weight gain, because " cortisol mobilises the liver to produce more glucose, but if the glucose is not metabolised it gets converted into stored fat in fat cells (adipose tissue)... cortisol directly alters appetite sensitivity and increases the cravings" The circadian system plays an important role in skin porousness (permeability). Permeability is increased in the evening and at night, and lowered in the morning and during the day. This means that there is more water loss in the evening, which is why we feel more skin itchiness towards the evening and night as our skin dries out which can lead to more chance of disease. But we also have more blood flow during the night to help fight them. Loads of STIs and infections go rampant. Sleep breaks down our immune response and the infections impact our sleep causing further infection.

Chapter 1: The Day Within discusses the 24-hour cycle. Circadian rhythm and the main Chronotypes, such as larks and owls.

Actually, something I really liked about this book was how deep it got molecularly. It was really interesting to read about, even if it did take me a few reads to understand it all.

It made the effects (me getting to bed sooner) last longer, and I'm hoping that'll continue even now that I'm finished with it.In his 1953 poem Days, Philip Larkin asks: 'What are days for? Where can we live but days?' He goes on with typical gloomy yet endearing angst: 'Ah, solving that question/Brings the priest and the doctor/In their long coats/Running over the fields.'

During this compelling conversation, we cover the science behind exposure to natural daylight at the right times. We talk chronotypes – and if there’s anything you can do to change being a lark or an owl. Russell explains the dangerous phenomenon of ‘microsleeps’ and why 4am is the most dangerous time to be on the roads. And we cover the unique problems faced by night-shift workers and new parents, including what they, their families and employers can do to mitigate their health and safety. 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. Tryptophan an amino acid, may aid sleep as it's a precursor to the neurotransmitter serotonin, the hormone melatonin, and vitamin B3. Full fat milk has Tryptophan. It's not just medical students. Foster (like Walker in fairness) has his intellectual baby. He thinks that sleep science should change the face of the school curriculum: Honma Prize (Japan), David G. Cogan Award (USA), Zoological Society Scientific and Edridge-Green Medals (UK)A couple of minor points do differ: Foster suggests use of Tryptophan-containing foods to boost serotonin and melatonin levels, helping both sleep and mood (glass of whole milk before bed? yes please). He also refutes the idea that it is the blue light from our devices that keeps us awake, but rather the whole stimulation effect of playing on a computer (absence of evidence in not evidence of absence). For my part I begrudge Foster for this revelation as it is easier to follow a recommendation if there are multiple reasons for doing so (and now I've lost a reason to not look at my phone before bed, which I'm sure doesn't help). 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. the extraordinary effects the time we take our medication can have on our risk of life-threatening conditions, such as strokes a b "Russell Foster, BSc, PhD, FRS". Oxford Neuroscience. The Medical Sciences Division, University of Oxford. 2008 . Retrieved 24 January 2010. 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.
