It looks as though a nap can help increase learning capacity, perhaps by clearing out a backlog of facts and making room for more. From the article:
“It’s as though the e-mail inbox in your hippocampus is full and, until you sleep and clear out those fact e-mails, you’re not going to receive any more mail. It’s just going to bounce until you sleep and move it into another folder.”
If you couple this with the boost in growth hormone that you can obtain from the same nap (a topic I want to post more on soon), it seems that it may be well worth scheduling a daily siesta.
A midday nap markedly boosts the brains learning capacity.

Another benefit of exercise: remaining young at a sub-cellular level. Telomeres (caps on the end of DNA strands) measure the “age” of a cell, and get shorter with time. In younger subjects (average age in their 20′s), exercise didn’t make a significant difference in telomere length, but in older subjects (average age of 51) there was as much as a 40% difference between the telomere lengths of sedentary individuals and serious runners. It’s unclear how much exercise is necessary to reap these benefits before experiencing diminishing returns.

I caught a cold this weekend. Sort of. Friday, I got really tired in the afternoon and that scratchy back-of-the-sinus feeling that means I am going to get sick. It always means that I am going to be laid out with a cold for the next week. I never get cute little cases of the sniffles; I get nailed with a debilitating disease and it takes me a week to kick the major symptoms every single time.
But not this time. Read the rest of this entry »
