Polyphasic sleep and Grow Hormone

[Rajec]

According to wikipedia:

HGH is synthesized and secreted from the anterior pituitary gland in a pulsatile manner throughout the day; surges of secretion occur at 3- to 5-hour intervals.[2] The plasma concentration of GH during these peaks may range from 5 to even 45 ng/mL.[6] The largest and most predictable of these GH peaks occurs about an hour after onset of sleep.[7] Otherwise there is wide variation between days and individuals. Nearly fifty percent of HGH secretion occurs during the third and fourth REM sleep stages. [8] Between the peaks, basal GH levels are low, usually less than 5 ng/mL for most of the day and night.[7] Additional analysis of the pulsatile profile of GH described in all cases less than 1 ng/ml for basal levels while maximum peaks were situated around 10-20 ng/mL.[9][10]

A number of factors are known to affect HGH secretion, such as age, gender, diet, exercise, stress, and other hormones.[2] Young adolescents secrete HGH at the rate of about 700 μg/day, while healthy adults secrete HGH at the rate of about 400 μg/day.[11]

How does polyphasic sleep work with this?
