Based on the above, here is a summary of the recommendations from Professor Panda’s research and his knowledge of this field: Light / sleep As Dr. Sachin Panda details in his new book, The Circadian Code, your health is governed by your circadian rhythms. Ignore this fact at your peril. Learn why when you eat makes all the difference to your body composition, metabolic health, hormone optimization and more!

circadian clocks affect our health beyond sleep How our body’s circadian clocks affect our health beyond sleep

One was about melatonin supplementation. While supplementation is not required, it can be incredibly useful for people struggling with sleep. The author covers this but then mentions a dose between 1mg and 5mg. This is way too high. For most people, this will have unwanted side-effects, such as waking up in the middle of the night or still feeling groggy the next morning. The correct dose for most people is 0.3mg (Alexander, 2018). If we average out the dose the author mentioned, he was off by a factor of 8. In his defense, such a dose is widespread, and most supplements have that dose, but it is incorrect nevertheless, and he should have known better. Most people are NOT eating enough protein, even if we as a society are eating more (which is a natural course of the industrial progression of society). The RDAs are prescriptions for avoiding malnourishment, not for optimizing health.Changes to the circadian rhythm and sleep occur once an individual begins abusing drugs and alcohol. Once an individual chooses to stop using drugs and alcohol, the circadian rhythm continues to be disrupted. [127] The first section of the book does talk about some of the circadian rhythm science, but mostly as a review of the history of the field, and of course the personal narrative of how the author entered the field.

Excellent book for information on the circadium rhythms of the bodies organs, brain, and how this effects how we digest foods, insulin spikes, hormonal weight gains and quality of sleep. As others pointed out the strength of this book was all in regards to Dr. Panda's timing research and how this directly impacts how much food effects us biochemically, and the downstream effects in regards to mood/energy/sleep.Folk GE, Thrift DL, Zimmerman MB, Reimann P (2006-12-01). "Mammalian activity – rest rhythms in Arctic continuous daylight". Biological Rhythm Research. 37 (6): 455–469. doi: 10.1080/09291010600738551. S2CID 84625255. Would local animals maintained under natural continuous daylight demonstrate the Aschoff effect described in previously published laboratory experiments using continuous light, in which rats' circadian activity patterns changed systematically to a longer period, expressing a 26-hour day of activity and rest? It does not. While caffeine is a diuretic, the water in the coffee compensates for this effect, and also the diuretic effect seems to fade for habitual drinkers (Killer, 2014).
