The sleep Foundation article examines the role of magnesium in sleep health, noting that this essential mineral supports nerve and muscle function, bone development, and heart rhythm regulation. Adequate magnesium levels are associated with improved sleep quality, longer sleep duration, and reduced daytime fatigue. Deficiency in magnesium may lead to sleep disturbances, including difficulty falling asleep and frequent awakenings. To enhance sleep and, consequently, brain health, the article recommends consuming magnesium-rich foods such as seeds, nuts, leafy greens, beans, and rice. For individuals unable to meet their magnesium needs through diet alone, supplements may be considered, with a general guideline to limit intake to 350 milligrams per day to avoid adverse effects. These recommendations are grounded in current nutritional science, emphasizing the importance of magnesium in maintaining healthy sleep patterns and cognitive function.
