The federal Centers for Disease Control and Prevention calls sleeplessness a public health concern. Good sleep helps brain plasticity, studies in mice have shown; poor sleep will make you fat and sad, and then will kill you. Where we're concerned, it'll help make you the athlete you want to be.
One of the negatives of being a triathlete, or having the personality that gravitates toward triathlon, is that each of us wants to get six things done in the time allotted for four. Something has to give; frequently that's time in the sack. The old, "I know it's bedtime, I'm almost done with ______________" When you have a couple minutes, this is a good read.

While on a Sunday bike ride recently, the topic of snoring came up. I ride with an older group, several of whom will have wine or beer with dinner most nights or maybe something
later in the evening and that snoring was becoming more of problem. Two agreed that it was considerably worse on weekend nights after a race.
I'd remembered a couple of things from med school that could contribute, one being alcohol that can overly relax the upper airway tissue. The other was having a fat neck, not much of a concern in the bike group. But I was sure there were other contributing factors of which we should be aware. The piece from Harvard below covers the subject pretty thoroughly, isn't overly "med speak" and could be a big help if one is interested. My thanks to the folks at Harvard.
