Industrial Exposure
Infrequent exposure to high doses of nitroglycerin can cause severe headaches known as "NG head" or "bang head". These headaches can be severe enough to incapacitate some people; however, humans develop a tolerance to and dependence on nitroglycerin after long-term exposure. Withdrawal can (rarely) be fatal; withdrawal symptoms include headaches and heart problems; with re-exposure to nitroglycerin, these symptoms may disappear.
For workers in nitroglycerin (NTG) manufacturing facilities, this can result in a "Monday morning headache" phenomenon for those who experience regular nitroglycerin exposure in the workplace leading to the development of NTG tolerance for the vasodilating effects. Over the weekend the workers lose the tolerance to NTG and when they are reexposed on Monday the prominent vasodilation produces tachycardia, dizziness, and a headache.

Famous quotes containing the word industrial:
“Nearly all the Escapists in the long past have managed their own budget and their social relations so unsuccessfully that I wouldn’t want them for my landlords, or my bankers, or my neighbors. They were valuable, like powerful stimulants, only when they were left out of the social and industrial routine.”
—Willa Cather (1876–1947)
