"[Y]ou can manipulate different types of sleep to your advantage." #readingToday 

The really exciting thing about the connection between sleep and your state of mind is that you can manipulate different types of sleep to your advantage. If you want slow wave sleep to strengthen your neural representations of specific bits of knowledge, then it would be sensible to take a nap in the afternoon. On the other hand, if you want to strengthen emotional memories, it might be better to sleep longer in the morning, or take a morning nap. This isn’t a hard and fast prescription, of course, but that is because we are still exploring the roles of these various types of sleep. The association between time of day and sleep type is absolutely firm.
