It is important to study our sleep patterns.

If the most health-conscious among us have such deep swings in our shut-eye levels throughout the year, how much sleep are the rest of us losing? They are culture-related.

From data collected, it seems the things that cause us to lose the most sleep, on average, are sporting events, time changes, and holidays.

Few people really know the importance of sleep.

Everybody sleeps, but what people stay up late to catch—or wake up early in order not to miss—varies by culture.

Other studies have found that even infants in East Asia sleep about an hour less than European infants, so we're trying to figure out how culture shapes the way you sleep.

right now, to reduce the risk of sudden infant death syndrome, the American Academy of Pediatrics recommends that mothers not sleep in the same bed as their babies, but sleep in the same room.

That means they wake up hungry, they are hungry all day, and they go to sleep hungry.

That suggests that catch - up sleep may undo some but not all of the damage that sleep 32 deprivation causes, which is encouraging, given how many adults don't get the hours they need each night.

The most common topics they discussed included kids' sleep, nutrition, discipline, behavior problems and day care and preschool.

The relationship between getting more sleep and making better food choices is well-documented.
