- Poor sleep if low Vitamin D, Magnesium, or Vitamin B6 (NHANES) – June 2019
- Poor sleep associated with low vitamin D (again) – July 2017
Sleep category starts with
A few items in SLEEP category
- Sleep greatly improved by 50,000 IU of vitamin D once every two weeks – RCT Sept 2018
- Sleep disorders nicely treated by Vitamin D (50,000 IU twice a month) – RCT May 2017
- Sleep, Dr. Gominak and Vitamin D - several studies
- Restless Legs Syndrome dramatically reduced by vitamin D, etc
- On the job sleepiness 2.2X more likely if low vitamin D – Feb 2020
- Poor sleep 1.5 X more likely if less than 20 ng of Vitamin D – Feb 2019
- The Better Sleep Vitamin (Vitamin D) – nice 3 dollar book Feb 2015
- The worse the sleep apnea, the lower the vitamin D levels – meta-analysis 2017, 2020
- Vitamin D for better sleep video - Dec 2021
- 5X increase in sleep problems in a decade in US Veterans
- Sleep Apnea and Vitamin D - many studies
- Melatonin and Vitamin D - many studies does much more than improve sleep
Items in both categories Infant/Child and Sleep are listed here:
- Many sleep problems are associated with low Vitamin D (children in this case) - Jan 2022
- 2.5 X more health compaints in children and youths if low vitamin D – Jan 2021
- Sleepiness in children 1.7X more likely if low vitamin D – Nov 2020
- Children with low Vitamin D slept 1 hour less, had 1 hour later bedtimes – July 2020
- Sleep duration in 2 year olds proportional to Vitamin D levels – Dec 2019
- Children short sleep 12 percent more likely for each 1 ng lower vitamin D at birth – Oct 2018
- Sleep half hour longer if OK level of Vitamin D (2-year olds) – April 2018
Note: The study on this page is an observation study
You can increase Vitamin D levels in your child both before and after birth with Vitamin D supplementation
The study listed above found that increased vitamin D levels in children were assoicated with better sleeping
Highlights
•Low vitamin D levels have been associated with sleep troubles in adults.
•Five distinct sleep-duration trajectories were observed from age 2 to 5-6 years.
•Cord blood vitamin D levels were lower in children with a short-sleep trajectory.
Objective
25-hydroxyvitamin D (25OHD) deficiency has been associated with sleep disorders in adults. Only three cross-sectional studies were performed in children; they showed an association between 25OHD deficiency and both obstructive sleep apnea syndrome and primary snoring. No longitudinal study has been performed in children from the general population. We analyzed the association between cord-blood vitamin D levels at birth and night-sleep duration trajectories for children between 2 and 5-6 years old in a non-clinical cohort.
Method
We included 264 children from the French EDEN mother-child birth-cohort with cord-blood 25OHD level determined by radio-immunoassay at birth, and night-sleep trajectories for children between 2 and 5-6 years old obtained by the group-based trajectory modeling method. Associations between 25OHD and sleep trajectories were assessed by multinomial logistic regression adjusted for maternal and child characteristics.
Results
The trajectories short sleep (<10h30/night), medium-low sleep (10h30-11h00/night), medium-high sleep (≈11h30/night), long sleep (≥11h30/night) and changing sleep (decreased from ≥11h30 to 10h30-11h00/night) represented 5%, 46%, 37%, 4% and 8% of the children, respectively. The mean 25OHD level was 19 ng/ml (SD=11, range 3 to 63). It was 12 (SD=7), 20 (SD=11), 19 (SD=10), 14 (SD=7) and 16 (SD=8) ng/ml for children with short, medium-low, medium-high, long and changing sleep trajectories, respectively.
On adjusted analysis, for each 1-ng/ml decrease in 25OHD level, the odds of belonging to the short sleep versus medium-high sleep trajectory was increased (odds ratio =1.12, 95% confidence interval [1.01-1.25]). We found no other significant association between 25OHD level and other trajectories.
Conclusion
A low 25OHD level at birth may be associated with an increased probability of being a persistent short sleeper in preschool years. These results need confirmation.
