What About Turning White Overnight?
A good scare, legend has it, can turn hair white overnight. Martyr Thomas
More and the notorious Marie Antoinette supposedly went “white” the night
before their executions.
What about Cooper? His new book, just out, titled A Memoir of War,
Disasters, and Survival, recounts many harrowing adventures. Could his
exploits have turned him white?
Of course, existing hair cannot “turn” any color because the part above the skin
is already whatever color it is. One explanation for this “white overnight
phenomenon,” is that the dark hairs suddenly fall victim to an autoimmune
condition called alopecia areata, which can cause dark hairs to fall out
overnight -- leaving the white ones.
Bank adds that the dark hair can fall out in quite large quantities in a short
period of time and you might not notice. “I know that sounds weird,” he says,
“but some goes down the drain. You may not notice.”
He also points out that going gray does not mean that your body’s aging
process has speeded up. You aren’t suddenly going to lose function in other
areas.
