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.
Anvil Lightning: A positive lightning bolt which develops in the anvil, or top of the thunderstorm cloud, and travels generally straight down to strike the ground. Heat Lightning: Lightning from a thunderstorm that is too far away to be heard. Lightning Facts: - Lightning causes an average of 80 deaths and 300 injuries each year. - The energy from one lightning flash could light a 100 watt light bulb for more than 3 months. - Only about 10% of people that are struck are actually killed. 90% survive, but nearly 25% of these survivors suffer long term psychological or physiological trauma. - 92% of lightning injuries and deaths occur between May and September.
