In the navy I preferred the night shifts. Nice and quiet. Day shifts were hectic, always stupid shit happening. Night shifts in the CIC were cozy, chill, having some coffee together, making grilled cheese sandwiches, being able to do work in full concentration as no one bothers you constantly. On the bridge it was even better. Extreme darkness, having nice conversations with your colleagues while watching the stars and the lights of other ships on the horizon. Only downside is the night shift has to get out of bed for fire drills etc during the day, so sometimes that leaves you with only 2h of sleep every day during sea trials. But that’s only 2 to 6 weeks of sleep deprivation so not all too bad imo.
