Any type of non-monophasic schedule is fighting the biological make up of sleep times. That is, humans have slept for a single block during the night for thousands of years, and it is therefore less restorative for the body to sleep at alternative hours.
The transition period is particularly dangerous because it is self-inflicted sleep deprivation. This opens the door for all types of sleep disorders such as narcolepsy, sleep apnea, bipolar and some circadian rhythym sleep disorders.
The patterns can be unsocial or inconvenient for others.
Depending on your sleep schedule, it might be difficult to go out for more than a few hours.
Uhh, those were all things that are in the article... So? Besides, no offense, but I believe the article is more trustworthy than an uncited statement.
