Sleep: The Do’s and Dont’s of This Crucial Tool

Working at sea means long hours, shifting schedules, and unpredictable sleep patterns. Yet sleep is one of the most powerful tools a crew member has for maintaining health, performance, and emotional stability.

We recently spoke with Michael from MP Tech, who specialises in circadian lighting solutions for yachts. Even if your vessel does not yet have circadian friendly lighting installed, there are simple habits that can significantly improve your sleep quality with immediate effect.

The Do’s

• Get morning sunlight

   Step outside within 30 minutes of waking. Natural light signals your body to switch into wake mode and start building sleep pressure for later.

• Wake at a consistent time

   Consistency is one of the best ways to protect your circadian rhythm.

  
  

• Absorb evening natural light where possible

   The green and red light wavelengths at sunset help trigger melatonin. Even a short step outside can make a difference.

  
  

• Support your sleep environment

   Aim for a cool, dark, quiet cabin. Reduce noise and heat sources where possible.

  
  

• Use gentle lighting after night watch

   Swap bright white cabin lights for warm, low intensity lamps to avoid confusing your brain into “wake mode”.

  
  

• Choose light pre sleep nutrition

   Herbal teas, magnesium, or L theanine are helpful. Heavy meals signal your body to stay alert.

The Dont’s

• Do not overuse melatonin

  Melatonin helps you fall asleep when shifting time zones, but should not be a nightly habit. Long term use can reduce natural hormone production. When needed, a very small amount (around 2 mg) is enough.

• Do not rely on caffeine to stay alert

  Late shift coffees and energy drinks disrupt your ability to unwind when you finally get off duty.

• Do not ignore sleep pressure

  If you wake late, spend the day under artificial light, and stay on devices right until bed, you are fighting your biology.

Why all of this matters

Healthy sleep helps your body complete all four restorative stages. That means better mood, stronger immunity, faster reaction times, clearer decision making, and more patience with the rest of the team.

Or as Michael says:

Everything is better after a good night of real sleep.
