Health
Chinook winds are said to sometimes cause a sharp increase in the number of migraine headaches suffered by the locals, and are often called "chinook headaches". At least one study conducted by the department of clinical neurosciences at the University of Calgary supports that belief. They are popularly believed to increase irritability and sleeplessness. In mid-winter over major centres such as Calgary, Chinooks can often override cold air in the city, trapping the pollutants in the cold air and causing inversion smog. At such times, it is possible for it to be cold at street level and much warmer at the tops of the skyscrapers and in higher terrain. In 1983, on the 45th floor of the Petro-Canada Center, carpenters worked shirtless in 12°C, windy conditions (temperature reported to them by overhead crane operator), but were chagrined to find out the street temperature was still -20°C as they left work at 3:30 that afternoon.

Famous quotes containing the word health:
“In health of mind and body, men should see with their own eyes, hear and speak without trumpets, walk on their feet, not on wheels, and work and war with their arms, not with engine-beams, nor rifles warranted to kill twenty men at a shot before you can see them.”
—John Ruskin (1819–1900)
“Any balance we achieve between adult and parental identities, between children’s and our own needs, works only for a time—because, as one father says, “It’s a new ball game just about every week.” So we are always in the process of learning to be parents.”
—Joan Sheingold Ditzion, Dennie, and Palmer Wolf. Ourselves and Our Children, by Boston Women’s Health Book Collective, ch. 2 (1978)
“The filth and noise of the crowded streets soon destroy the elasticity of health which belongs to the country boy.”
—Rutherford Birchard Hayes (1822–1893)
