There has been a significant amount of research into the role that seasonal variations in the levels of vitamin D may play in risk of MS and seasonal variation in relapses, but researchers have also been investigating whether the seasonal variation in melatonin could play a part in this.
A research paper was published this week by a team of researchers in Argentina. They investigated how seasonal factors affect patients with relapsing-remitting MS and found a correlation between those with higher melatonin levels experiencing fewer relapses.
These findings provide insight into how higher levels of melatonin in winter months could have a link to the seasonal changes in relapse activity seen in people with MS.
While this study suggests that there may be a link between melatonin and MS, further studies are needed to increase understanding of how it contributes to the progression and activity of the disease.
