Sleepless in Asia

Sleepless in Singapore, said The Sunday Times (Singapore) headline.

Apparently half the nation are nightbirds. A survey found that one in two stay up past midnight, with half (27 per
cent) hitting the sack between midnight and 1am, and the other half
turning in after 1am.
Over a third (37 per cent) of the 500 polled rise between 6am and 7am. Another 31 per cent get up between 7am and 8am.
The majority (59 per cent)
sleep six to seven hours, while 3 per cent survive on only five hours
of sleep.
But Singaporeans take it easy compared with the Japanese.
The Japanese sleep the least, with four out of 10 getting six hours or less.
The Portuguese are the most likely to stay up late, showed the survey by AC Neilsen. But the Taiwanese come next. In fact, seven of the top 10 nightbird nations are Asian. Singapore ranks seventh on the list. The only Europeans on the list are the Portuguese, Spanish and Italians. And all three are known for siestas or afternoon naps, notes an Asian site. The implication, of course, is that we don’t do that.
The Aussies and the Kiwis are the biggest sleepers in Asia-Pacific, with 31 per cent of Aussies and 28 per cent of Kiwis sleeping nine hours a day. The survey found 24 per cent of Aussies and 19 per cent of Kiwis are in bed by 10 pm, compared with just 2 per cent of Singaporeans.
Indonesians are the earliest risers in the region with nine in 10 out of bed by 7am.
The Taiwanese  are the last out of bed. Over a quarter (26 per cent) don’t get up until after 9am.
Asians differ from others  on another  count — the nightbirds here are more likely to be thirtysomethings rather than twentysomethings.
