Long term exposure to night shift work is associated with

increased risks for cardiovascular and gastrointestinal disease,

sleep disorders, altered personalities, above average accident

rates and menstrual irregularities. Restorative sleep loss during

the natural occurring rest phase, i.e., 11pm-7am results in a

decreased secretion of serum growth hormone. This limited

secretion produces a muscle fatigue sensation. In conjunction with

altered serum growth hormone levels, the serum cortisol level does

not rise sufficiently to respond to alert time activities. All

body functions are misaligned with subnormal body temperature

during peak activity time noted as a characteristic guide mark.



Recent research by Czeisler reveals an association between a

retinal photo receptor pathway and the ability to successfully

switch human nadir points under strictly controlled illumination

settings. Based on Circadian Rhythm Theory, dietary/social, and

light/dark cycle adaptation approaches, the hypothesis is that

hospital night shift workers who follow a light/dark cycle rather

than a dietary/social approach will present a normal body

temperature (98.6 degrees F) at 3am.



The sample population consisted of 22 night shift employees who

completed a somatic assessment survey, followed a light/dark cycle

or dietary/social interaction approach for a twenty-one day period.

The activity plan was specific for home sleep preparation, 3am body

temperature, sleep time accomplishment and suggested activity times

on a daily basis. It was nonspecific for dietary type and time.

The dietary plan employed specific feedback for time and type of

food eaten and 3am temperature, but nonspecific feedback for sleep

patterns and environment. Employees were also classified according

to the amount of illumination available at each nursing station.

Group A had 15 foot candles of illumination at desk level. Group

B had 50 foot candles of illumination at desk level.



The Wald Test of Significance for fixed effects and convariances

was used to accommodate an unbalanced design related to repeated

measures data. The Wald chi-square value for the dietary/activity

plan was 0.03. The P-value was 70.8. Day to day temperatures also

proved insignificant. A statistically significant value was

obtained for this good light versus poor light group comparison.

The chi-square value is 17.13, the P-value is less than 0.001.



Somatic symptoms experienced by the Hospital's night shift

employees matched those symptoms described in the literature.
