How little sodium/day is too low?

[Messermann]

I am in the process of getting into shape -- primarily to lower my blood pressure. I am eating very carefully. I am consuming far less sodium than I used to, and I am walking 8-9 miles/every 24 hour period.

I decided to tally up my actual sodium intake/day. It ranges from 278 mg/day to 638 mg/day, presuming there's not much sodium in the gallon of filtered tap water I consume each day. (The American Heart Association supports a 1,500 mg target for everyone.)

I really feel wonderful! Better than when I was on this exact diet and exercise plan in the past, except this time I am limiting sodium.

My question is, am I headed for trouble (e.g. Hyponatremia) if I keep my sodium intake this low? Will I have plenty of warning from my body to increase sodium before anything serious might happen? Thank you for any insights.
