You can take many steps in their everyday lives to improve their mental health, one of the main factors is sleep (1). A previous post looked at poor sleep and worsening stress levels (2).

Poor sleep can also impact tension, irritability, depression, confusion, reduced life satisfaction, or poor academic performance (3).

Yet more than 75% of young adults report getting less than 8 hours of sleep on average on weeknights over the last 2 weeks (4).

A recent study looked at of impact of omega 3s on sleep.

What was the study? (5)

  • This was a randomized, placebo-controlled, double-blinded, parallel-grouped study (5)
  • 66 healthy males and females, mean age 52.8 years (5)
  • Participants received 576 mg DHA and 284 mg EPA per day (n = 33), or corn oil (placebo group, n = 33), for 12 weeks (5)
  • Sleep was measured using a self reported scores (OSA-MA and POMS-2 tests) and objective sleep monitoring via a device (monitor that evaluates the sleep state by collecting breath, pulse, and body movement data) (5)
  • Blood omega 3 levels and dietary survey was also done.

What were the results? (5)

  • The study showed that 576 mg DHA and 284 mg EPA per day improved sleep quality (5)
  • Frequent dreaming also improved (5).
  • They theorized that the mechanism might be related to impact on serotonin and melatonin levels (5)

What are some caveats?

  • This is one of the first studies to show that low dose omega 3s can improve sleep quality (5).
  • This was a well designed randomized, double blind, placebo controlled, parallel grouped study with objective and subjective measures (5).
  • There are many other studies showing benefit from omega 3’s and sleep quality. (6)
  • While this study involved healthy participants, individuals with health conditions may need a higher dose of omega 3’s to find benefit (5).
  • Check with your health professional to ensure that Omega 3’s are appropriate for you as they may not be suitable for everyone.
  • Plant based omega 3’s may be an option for those who do not or cannot eat fish.
  • While this study was in middle aged adults (5) and a separate study found benefits in young adults (7) findings may not be generalizable to other populations with health conditions.
  • Further study in specific populations  with specific health conditions is needed.

What are some ways of improving sleep?

The American Academy of Sleep Medicine suggests the following ways to improve sleep (8):

  • Keep a consistent sleep schedule.
  • Get up at the same time every day, even on weekends or during vacations.
  • The National Sleep Foundation recommends 7 to 9 hours of sleep for young adults (9).
  • Don’t go to bed unless you are sleepy.
  • If you don’t fall asleep after 20 minutes, get out of bed.
  • Establish a relaxing bedtime routine.
  • Use your bed only for sleep and sex.
  • Make your bedroom quiet and relaxing. Keep the room at a comfortable, cool temperature.
  • Limit exposure to bright light in the evenings.
  • Turn off electronic devices at least 30 minutes before bedtime.
  • Don’t eat a large meal before bedtime. If you are hungry at night, eat a light, healthy snack.
  • Exercise regularly and maintain a healthy diet.
  • Avoid consuming caffeine in the late afternoon or evening.
  • Avoid consuming alcohol before bedtime.
  • Reduce your fluid intake before bedtime.
