The next stop along our walk around the clock is 9PM. Here you will learn about the importance of light timing. What happens at 9PM is anti-mirrored at 9AM, so commentary for both times are included together on this graphic.

9 PM & 9 AM

The changing thicknesses of the yellow and blue curves illustrates the effective weight of eye exposure impacting the delay or advance of melatonin onset. It is the balancing of these light timing occurrences, against each other (how much eye light exposure occurs during the blue time versus how much eye light exposure occurs in the yellow time) that determines the final moment when melatonin onset will occur for the next 24-hour cycle. If the final outcome of the blue versus yellow eye light exposure amounts weighs in favor of phase ADVANCING, then this means that the next melatonin onset will occur EARLIER. If the balance tips toward DELAY, than the onset will occur LATER for the following cycle.

If Alan and James were suddenly placed in permanent darkness, a different effect would result. The master clocks in their brains would still continue to follow the same 24-hour schedule releasing melatonin into the bloodstream at the same time except approximately 15 minutes later on each successive 24-hour period. This is because the master clock in the brain relies on light timing, originally only provided by nature, to advance or delay the brain’s master clock. Light timing drives the RESET ADJUSTMENTS to advance or delay the 24- hour and 15 minute master clock in the brain.

Regarding TIMIMG DELAY we have to understand how important it is that Alan is wearing melatonin onset eyewear and James is not. Both men are in homes lighted artificially during the peak moment that eye light exposure delays melatonin onset for the next 24-hour cycle. Alan’s melatonin onset eyewear has defeated the melatonin onset delay that James will experience. A person will daily require a little more “blue” time eye exposure than “yellow” time, to correct the 15 minute slowness of the master clock in the brain.

Now we move on to the next important event in Alan’s and James’ clock which occurred at 10:30 PM.


10:30 PM
10:30 PM

As stated earlier, James’ melatonin onset occurs later that Alan’s although both men go to sleep and awake at the same times.  James’ REM sleep will be shallower than Alan’s, and his nightly cellular repair will be less than Alan’s. Furthermore, his following day’s productivity will be less than Alan’s. James only gained more productivity than Alan just prior to sleeping. James’ productivity in the morning will be much less than Alan’s in the morning and overall Alan will be better off (physically, mentally and emotionally) than James during the following day. What Alan lost in productivity during the evening, compared to James, he more than made up the next day and especially in the morning hours before lunch.

Our next point of interest is 3 AM, which is the point in time where eye light exposure switches from delaying to advancing melatonin onset, so click on the advancing item on the table of contents below to continue.
