Vitamin D status may impact treatment outcome of insomnia

Posted on: January 5, 2018   by  Missy Sturges & John Canell, MD


Finally, researchers, physicians and health conscious individuals are beginning to agree that vitamin D is an important component of healthy living.

Thousands of studies have been conducted, evaluating the role of vitamin D status in an array of health outcomes. These findings have linked vitamin D deficiency with at least 45 chronic health conditions, and according to research, it appears yet another health condition can be added to this list: insomnia.

If you have a difficult time falling and/or staying asleep, or feel restless at night and fatigued during the day, you may be one of approximately 80 million Americans who struggle with a sleep disorder.

Sleep is a life-sustaining function of our bodies. Although many of us believe sleep is required to enable the mind and body to rest, this is actually a time for the body to actively repair tissues, consolidate memories and restore what is lost while awake.

Those of us who have been deprived of sleep for a prolonged period of time can attest to the negative impact this has on our health. From memory loss and mood changes to impaired judgement and decreased physical drive, sleep disorders undoubtedly pose a serious threat to long-term health. In fact, unmanaged sleep disorders have been associated with an increased risk for heart disease, stroke and mortality.

So, how may vitamin D affect sleep? Research suggests that vitamin D may be a useful tool in managing sleep disorders due to its ability to regulate circadian rhythms, our body’s internal clock that instructs us when to sleep, eat and rest. This theory has been supported by several studies which have found low vitamin D status is linked with disordered sleeping habits.
