Observation: In the Philippines, most parents force their kids to take a siesta. These are taken around 1 or 2 in the afternoon. However, some parents fail to wake their kids up after 3 hours of sleep. In this case, these kids are up till the wee hours of the night, making their sleeping habits more complicated than it should be.

Regarding the article, I guess one should just do what works for them (their body). Some people find it necessary to get 8 hours of sleep, and some are okay with six.
