If it's too low early morning, this possibly is not taking place, so glucose drops too low. If this is occurring, I suggest you try taking 4000 to 8000mg/day glutamine at night. This amino acid can be used by the brain in place of glucose, but being an amino it doesn't cause a sharp drop in blood glucose levels.
Sometimes, heat lightning isn't lightning at all, but a cloud reflection of lightning from a very distant storm. In other instances, it is regular lightning which has formed far off in the distance, making a flash instead of a recognizable lightning bolt.
First off, itâs impossible to have lightning without thunder and itâs impossible to have thunder without lightning. Heat lightning is nothing more than seeing lightning and not hearing the thunder, because the storm is too far away. Lightning is pretty darn bright and can be seen for tens of miles. Thunder is a compression wave and will dissipate with time and distance. Under excellent conditions, thunder can be heard about 12 miles away from the lightning strike. However most of the time conditions arenât this good and we usually canât hear thunder any more than about 5 miles away.
