When in doubt, lie down in the shade, flat on your back, arms
stretched out to the sides, a bottle of water in one hand and a bottle
of juice in the other. Stay there until one bottle or the other is
empty, not less than five minutes.

That covers you for overheating, dehydration, low blood sugar, and
fatigue.
