    Area of Science:

    • Sleep science
    • Psychology
    • Cardiology

    Background:

    • Type A personality is linked to coronary-prone behaviors.
    • Chronic REM sleep deprivation has been hypothesized as a cause for Type A traits and coronary-proneness.

    Purpose of the Study:

    • To investigate sleep differences between Type A and Type B students.
    • To test the hypothesis that Type A individuals experience REM deprivation.

    Main Methods:

    • Eight Type A and eight Type B students participated.
    • Sleep was monitored in a laboratory for three consecutive nights.

    Main Results:

    • Type A students exhibited significantly more fragmented sleep.
    • Type A students had more spontaneous awakenings during sleep.

  • No significant differences in REM pressure were observed between Type A and Type B students.

    • Conclusions:

    • Type A behavior is associated with sleep fragmentation, not REM deprivation.
    • The hypothesis linking Type A personality, coronary-proneness, and chronic REM deprivation is not supported by this study.
