Sleep can be disrupted throughout the night, leaving a foggy head for the next morning. Which surprising vitamin has been shown to help with a good night’s kip?
According to “The Sleep Doctor” Michael Breus, clinical psychologist: “Vitamin D is catching a lot of interest for its potential benefits for sleep.”
Researchers, from the department of Psychobiology at a university in Brazil, found a link between a vitamin D deficiency and sleep duration.
The link between vitamin D deficiency and a limited amount of sleep was seen in those aged 50 and older.
The Sleep Doctor postulated: “Vitamin D may influence sleep by helping to regulate our circadian clocks.”
The Sleep Foundation explains that the circadian rhythm is an internal body clock.
It’s also known as the sleep/wake cycle and is controlled by a portion of the brain called the hypothalamus.
The Sleep Doctor then referenced research that shows “vitamin D may activate two circadian clock genes which, in turn, controls the 24-hour circadian rhythms”.
He continued: “Light and darkness, we know, are the primary regulators of our internal bio clocks.”
The Sleep Foundation states that darkness sends a signal to the hypothalamus that it’s time to feel tired.
The hormone melatonin is then released by the brain to induce the feeling of fatigue.
“Sunlight is also our single best source of vitamin D,” The Sleep Doctor added.
