In a context of seeking a better balance between personal and professional life and labor shortages, the use of 12-hour alternating day-night shifts has become more common in work organizations, particularly in healthcare facilities. This work pattern combines exposure to alternating day and night shifts with long working hours, raising questions about its effects on health, particularly sleep quality and cardiovascular risk. Staff working alternating day/night or night shifts are at risk of cardiovascular disease, particularly in connection with sleep deprivation and the adoption of individual behaviors that increase the risk (smoking, poor diet, alcohol consumption, smoking and low physical activity). However sleep education is not integrated in a personalized way into the prevention advice provided by occupational health services.
Therefore, this study aims to investigate the effects of a 6-month sleep education program conducted by occupational health nursing staff, on the sleep duration of healthcare workers newly exposed to alternating 12-hour day and night shifts.
Being a paramedical caregiverr (nurse or care assistant)

Working at least 80% of a full-time equivalent post
Staff employed at a hospital listed among the investigating centers
Nursing staff and nursing assistants who have been exposed for more than six months to alternating 12-hour shifts or atypical working hours (two eight-hour shifts, three eight-hour shifts or night shifts) during their professional career

Parallel
Sleep educational
BehavioralParticipants will undergo : * standardized monitoring initially (M0), then at 6 months (M6) and 12 months (M12) * a personalized educational program, including an initial consultation with a sleep doctor and a nurse, followed by monthly follow-ups with an occupational health nurse.
Effect of a 6-month sleep education program
Evaluate the effect of a 6-month sleep education program conducted by occupational health nursing staff on the sleep duration of nursing assistants newly exposed to alternating 12-hour day and night shifts.Absolute difference in average sleep duration (in minutes) measured over 14 days from an actigraph worn at the wrist, between Baseline (M0) and at 6 months (M6).
Assess the impact of the sleep education program on sleep quality
The Pittsburgh Sleep Quality Index (PSQI) comprises 24 items, with scores ranging from 0 to 21, where a score \> 5 indicates poor sleep quality)
Assess the impact of the sleep education program on participant state of health
Measure of cardiac frequency
Assess the impact of the sleep education program on quality of life
The Short Form 36 (SF-36) will be used to assess quality of life. This 36-item questionnaire includes 8 sub-scores ranging from 0 (minimum quality of life) to 100 (maximum well-being).
Assess the impact of the sleep education program on accidentology
Number of commuting accidents, workplace accidents, road accidents, near misses related to drowsiness
