Several factors contribute to daytime fatigue in the nursing profession: - Long shifts: Nurses often work shifts that exceed the standard 8-hour workday, sometimes extending to 12 hours or more. - Irregular schedules: Rotating shifts and night shifts can disrupt circadian rhythms, making it difficult to maintain a consistent sleep pattern. - High-stress environment: The demands of patient care, emotional stress, and the high-stakes nature of the job can all contribute to fatigue. - Physical demands: Nursing is a physically demanding profession that requires long periods of standing, lifting patients, and other strenuous activities.
