A deep sleep at night is the privilege of a few. Stress, eating disorders and psychological disorders negatively affect the quality of rest. Demand for magnesium supplements for better sleep has increased in doctors’ offices. But does it really help?
According to registered dietitian Larissa Leal of the Saues Clinic, it can be really beneficial for people to get a deep, restful night’s sleep. However, the indication does not apply to people with insomnia.
Unlike the hormone melatonin used to induce sleep, magnesium is indicated to maintain the quality of matter after a person has fallen asleep, for sleep that goes through all stages. According to Larisa, the mineral reduces cortisol, better known as the stress hormone, and has a relaxing effect on the body. This combination contributes to a restful sleep.
Larissa explains that a balance of macronutrients (like carbs, protein, and fat) and micronutrients (magnesium and iron) is good for the body because it keeps the circadian cycle in check, keeping us awake during the day and sleepy at night.
Supplementation also indirectly contributes to the prevention of chronic diseases, premenstrual tension (PMS) and cardiovascular diseases.
“Sleep is one of the pillars of quality of life, when it is released it is associated with chronic diseases such as high blood pressure and obesity, as well as an increase in inflammatory markers with decreased immunity,” says the doctor.
A survey carried out by the Sono Institute of São Paulo in 2021 revealed that difficulty sleeping affected almost 70% of Brazilians in the pandemic. About 60% of the 1,600 people interviewed said they wake up frequently during the night.
Magnesium is found in green leafy vegetables (such as watercress), nuts, whole grains, and green leafy vegetables (such as broccoli). Although they contain large amounts of the mineral, food alone may not be enough for people who are deficient in this substance.
In this case, the doctor would suggest supplementation with professional follow-up until the levels stabilize. After that, the patients can continue to eat the fortified food.
