Don\’t overdo it with the water! How often do we hear about the importance of adequate hydration during exercise? Plenty often, but so far I\’ve seen far less attention given to hyponatremia.

Yes, it is possible to drink too much water. Scads of water with too little in the way of electrolytes (especially sodium) causes the blood\’s sodium level to drop too low; in effect, it gets diluted. The consequences can be serious; in a worst-case scenario, death can result.

Although it\’s now September, the heat and humidity haven\’t yet abated. Not where I live, anyway! It probably won\’t really cool off for another month. Advice for hot weather riding is therefore not out of place in a September blog; especially considering that it can get into the 80s on Christmas Day here!

To get back to hyponatremia, I don\’t think we need to be terrified of riding in hot, humid weather. Ride early in the day, if possible. Even after the sun sets, the day\’s heat lingers. Yes, do take plenty of water; use a Camel-Bak if necessary. If you\’ll be out more than an hour, take along some kind of electrolyte drink.

Is drinking by thirst the best way? Some say it is; others disagree. Back to the old admonition, I guess: Moderation in All Things. Or, in other words, don\’t overdo it.
