...Circadian dysrhythmia, the medical name for jet lag, is a recognized disorder. Zooming through time zones upsets biological clocks and desynchronizes functions such as sleep, hunger, elimination and sex. The body resists its forcible relocation in the external world with numerous warning signals: sleepiness, insomnia, dimmed vision, throat discomfort and irritability. A pack-a-day smoker, Haig also would be affected by high altitudes more than the nonsmoker. Some studies indicate more disturbing effects of jet megatravel: a diminution in mental ability, and mild amnesia about recent events. The heart undergoes a special series of reactions during intercontinental travel. Levels...

Though the clock now rules the industrial universe, it is a mechanical chronos that has been foreign to most human experience. All organisms have "circadian" rhythms (from circa, about, and diem, day), whose periodicity is a response to biological needs. The psychological sense of time is one of durée, of bleak moments and moments of bliss, of the agony of time prolonged and time eclipsed; memory is not the function of a "length" of time, but of its intensity. Most important, in the area of work-the experience that shapes character-time was long considered a function...
...Circadian Rhythms. NASA has suggested that such nighttime illumination would be useful in search-and-rescue work, in spacecraft-recovery operations and in lengthening short winter days at high latitudes. But its spokesmen have carefully avoided discussing another obvious application: military use in Viet Nam. A single mirror satellite in synchronous orbit over Southeast Asia could cast light on an area stretching from Saigon all the way to Pointe de Camau, at the southern tip of Viet Nam, thus depriving guerrillas of the protection of darkness...
Despite these practical applications, many scientists share Physicist Everhart's concern about the space mirrors. Biologists fear that decreasing the hours of darkness could disturb the delicate circadian rhythms that control many life processes. Other scientists envision a mirror swinging out of control, reflecting sunlight indiscriminately over the night face of the earth. Even more alarming to Everhart is the potential proliferation of the mirrors. "Farmers would demand them to plow their fields at night," he says, "and resort owners would want them to light their lakes and pools." Singlehanded, Everhart has mounted an intensive campaign to rally...
