Dehydration may show up as a headache, tiredness, light headedness, nausea or anxiety. If you experience any of these symptoms, drink 1 to 2 glasses of pure water and notice if you feel better.
If you have not eaten for a while you could be having a low blood sugar headache. Eat something, but not the candy bar! Try orange juice and a few crackers – the sugar and other “good stuff” in the juice will pick up sugar level and the crackers will reduce potential of crash. Notice if you feel better.
