Hypothesis
Is there a connection between psychosomatic complaints and circadian rhythm irregularity in healthy students?
Conclusion
Psychosomatic symptoms, particularly anxiety, may be associated with irregularity in melatonin and growth hormone rhythms, which can be altered by basic lifestyle habits even in healthy students.
Supporting Evidence
- Students with irregular circadian rhythms reported more psychosomatic complaints, especially anxiety.
- Melatonin and growth hormone levels were significantly correlated in students with regular circadian rhythms.
- The study suggests that lifestyle habits can influence hormonal rhythms and psychosomatic health.
Takeaway
Students who have trouble sleeping and feel anxious might have their bodies out of sync with their natural rhythms, which can make them feel worse.
Methodology
Fifteen healthy students' salivary melatonin and growth hormone levels were measured five times a day, and they rated their psychosomatic symptoms twice daily.
Potential Biases
The small sample size may limit the generalizability of the findings.
Limitations
The study had a small sample size, potential sleep disruption from sample collection, and possible gender differences affecting results.
Participant Demographics
15 healthy Japanese university students (7 men and 8 women) aged 21 to 22.
