Human Circadian rhythms cycle on a. 25 hour timescale. 8 hour timescale. 24 hour timescale. Removal of alcohol from the blood stream. Can be speeded up by sleeping. Cannot be speeded up. Can be speeded up by drinking strong coffee. . For a person with normal Circadian rhythms, the body temperature will be lowest. Between 4 and 6 o'clock in the morning. Upon waking. At midday. If a maintenance engineer has a cold or flu he should. Only absent himself from duty if his work contract includes sickness pay. Only absent himself from duty if there are no staff shortages at his workplace or within his work team.. Absent himself from duty until fully recovered, regardless of other factors. Consumption of alcohol. Increases mental and physical reaction times. Has no affect upon mental and physical reaction times. Decreases mental and physical reaction times. Alertness and performance is reduced when the body temperature is. Above normal. Below normal. Either above or below normal. . A good rule of thumb for an adequate amount of sleep is. One hour of high quality sleep is good for two hours of activity. Two hours of high quality sleep is good for one hour of activity. One hour of high quality sleep is good for one hour of activity. Finding that familiar tasks (such as programming the video recorder) seems more complicated than usual, could be an early indication of. Acute stress. Chronic fatigue. A cold or flu. The only permitted stimulant is. Bromine. Caffeine. Amphetamine. Large amounts of caffeine can. Reduce anxiety and stress. Improve alertness and increase awareness. Cause anxiety, headaches and stress. . The symptoms of stress are. Irritability, forgetfulness, sickness, absence from work, drug and alcohol abuse. Indications of improved work performance.
