Sleep

Does Tart cherry juice help with sleep?

About 14% of young adults reported sleep difficulties (1)

There are many non medication strategies that can help improve sleep, and these have been discussed previously (2).

One study looked at tart cherry juice and its impact on sleep.

Why tart cherry juice?

Previous studies reported the positive effects of consumption of tart cherry juice on recovery in cyclists, soccer players, and marathoners (3,4,5). In addition, a study on healthy people reported that consumption of tart cherry juice can quickly promote sleep, cognition, and a decrease in the level of oxidative stress and training-related muscle damage (6,7).

Interestingly, tart cherry contains high concentrations of melatonin (8).  Melatonin is both a supplement and a substance created in the human body that helps to induce sleep (9,10).

Tart cherry juice has been shown to increase in the efficiency of objective sleep (11).

What was the study? (12)

22 participants were randomized to receive either 30 mls tart cherry juice or placebo given 5 times over 48 hours (12).

What was measured? (12)

Melatonin, stress hormone cortisol, and the quality of sleep after intermittent exhaustion exercise in female elite field hockey players (12).

What were the results? (12)

Tart cherry juice was found to improve sleep quality, but not affect changes in the levels of melatonin or the stress hormone, cortisol (12).

What are some caveats?

  • In my experience, some people may experience morning tiredness or vivid dreams.
  • This is a small study and further study is needed to verify the results.
  • Long term side effects are not known.
  • The benefit size may not be enough for everyone.
  • There are many factors impacting sleep and the combination of factors impacting any 1 person may not be the same as others, so the combination of strategies that work to help improve sleep may vary from person to person.

What are some helpful strategies for sleep?

The American Academy of Sleep Medicine suggests the following ways to improve sleep (13):

  • Keep a consistent sleep schedule.
  • Get up at the same time every day, even on weekends or during vacations.
  • Don’t go to bed unless you are sleepy.
  • Other strategies:

Poor sleep and poor grades might go together

College students might stay up late or have an erratic sleep schedule for a variety of reasons.

A recent study looked at the impact of sleep pattern on grades.

Who was studied? (1,2)

  • 61 undergraduate students at Harvard college
  • They were asked to keep a sleep diary for 30 days.

What did the investigators find? (1,2)

Compared to peers, students reporting irregular patterns of sleep and wakefulness had:

  • Lower grade point averages.
  • Delays in the times people went to bed and woke up compared to more normal sleep/wake times.
  • Upto 3 hour delay in melatonin (sleep related hormone) release compared to students with regularly scheduled sleep and wakefulness pattern.

What are some caveats?

  • Poor sleep can impact almost every aspect of health and many parts of brain functioning, including learning, remembering, mood, energy level, decision making, etc.
  • This is a small study and does not prove cause-and-effect (2).
  • Students with erratic sleep schedules ended up sleeping the same number of hours as those with a regular sleep schedule. (1,2).
  • Study participants might have an erratic sleep schedule for a variety of reasons.

What are some ways of improving sleep?

The American Academy of Sleep Medicine suggests the following ways to improve sleep (3):

  • Keep a consistent sleep schedule.
  • Get up at the same time every day, even on weekends or during vacations.
  • Plan to get at least 7 hours of sleep.
  • 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.

Anything else?

  • Some people may need to eliminate caffeine or alcohol completely.
  • If you have to use electronics in the evenings, consider BLUEBLOCKERS.
