The Four Types of Sleep Schedules

The Four Types of Sleep Schedules - The Atlantic

Via The Atlantic:  ‘“[O]wls”—people who prefer to wake up late and are more alert in the evenings [are] one of two basic chronotypes, or preferred sleep schedules. The other is “larks,” or crazy people those who prefer early mornings.But now, scientists in Russia are proposing that there are actually four chronotypes: In addition to early and late risers, they say, there are also people who feel energetic in both the mornings and evenings, as well as people who feel lethargic all day.’

I’ve been one of the lucky ones. However, I think one’s sleep type can change with age, and I am clearly losing my ability to burn the candle at both ends.
