Magnesium for Sleep – Sources, Benefits and How to use it?
Overcoming sleep trouble and insomnia is a daunting task for many. Besides various breathing exercises, lifestyle changes, and other methods, taking supplements is a popular way to achieve deep and restful sleep.
To date, melatonin is the most popular supplement to help you doze off. This is because it imitates your body’s sleep hormone. However, another supplement has been recently discovered for better sleep and is grabbing the limelight. It is magnesium for sleep.
Curious about how does magnesium helps you sleep? Read on to unravel the mystery.
What is Magnesium?
Magnesium counts among the 24 essential minerals and vitamins required by our body for smooth and healthy functioning.
Wondering what magnesium is good for? Magnesium plays a vital role in over 600 cellular reactions happening inside our bodies. It is especially useful for bone health and proper muscle, brain, and heart functioning. It also helps maintain a healthy immune system, manage blood pressure, and plays a pivotal role in protein and energy production. It is also believed to improve sleep.
The magnesium requirement for an adult is 400-420 mg daily for men and 310-320 mg for women. Despite this large requirement, our body does not produce magnesium independently; thus, we rely on diet and supplements to meet the required bar.
How Does Magnesium Help You Sleep?
Magnesium is emerging as the new supplement for better sleep aid. Various pieces of research are conducted on magnesium and sleep and their correlation. While we do not have enough concrete evidence on whether magnesium is good for sleep, a lack of magnesium enhances sleep troubles.
The below-listed insights reveal the potential of how magnesium helps you sleep.
1. Magnesium Helps Your Brain and Body Relax
You cannot sleep restfully unless your brain and body are completely relaxed. Studies indicate that magnesium helps activate the parasympathetic nervous system, which functions to calm and relax you.
For it, magnesium regulates the neurotransmitters responsible for sending signals throughout the brain and the nervous system. It also regulates melatonin, the hormone responsible for the sleep-wake cycles of our body.
Another way magnesium helps you relax is by binding itself to the gamma-aminobutyric acid (GABA) receptors, which are responsible for quieting down nerve activity. You find the same neurotransmitter in popular sleep drugs like Ambien.
Overall, the effect of magnesium on sleep and anxiety is manifested by calming the mind and body.
2. Regulates Stress and Anxiety
A critical part of calming yourself is reducing stress and anxiety. We already know that magnesium impacts the body’s parasympathetic nervous system and increases the body’s GABA levels for more restorative sleep.
Magnesium also affects the sympathetic nervous system, the ‘fight-or-flight’ response system. As a result, it leaves you in a heightened state of arousal.
Magnesium supplements help these two systems reach an equilibrium. A German study showed that when magnesium sleep aid was used, it helped in reducing sleep disorders, depression, stress, poor concentration and irritability.
3. Improve Restless Leg Syndrome
Restless leg syndrome is a disorder in which you experience an uncontrollable and uncomfortable urge to move or shake your legs. It gives you a “pins and needles” feeling. It triggers a sense of inactivity, and shaking of the leg relieves it.
The condition tends to worsen at night and leads to insomnia. But regular intake of magnesium before bed reduces the symptoms and helps you sleep better.
4. Depression and Mood
Depression and mood disorders are other leading causes of restlessness, insomnia, and other sleep disorders. According to research, one of the benefits of magnesium supplement intake is the reduction of depression and associated symptoms, that in turn helps you sleep better.
5. Digestion And Gut Health
Any digestive issue will make you uneasy and uncomfortable, disrupting your sleep. While the studies are still in their primitive stage, a link between gut health and magnesium is increasingly being examined.
A research in Denmark indicated that magnesium deficiency triggered an imbalance of healthy microbiota in the gut and caused digestive issues and even depressive-like behaviour.
6. Aches, Pains, & Muscle Cramps
Various research also finds an increased link between magnesium deficiency and twitches, spasms, muscle cramps, and general weakness.
Taking magnesium at night helps improve leg cramps, among other things, to help people sleep better.
Other Benefits of Magnesium
Apart from sleep benefits, magnesium supplements also render several other benefits like:
- Magnesium plays a vital role in the bone-building process. Hence, when you use the best magnesium supplement for sleep, you also reduce bone loss or osteoporosis symptoms.
- Early research indicates magnesium supplements might reduce blood pressure marginally and minimise the chances of strokes or heart diseases. However, more authentication is still required.
- Magnesium plays a vital role in the breakdown of sugars in the body. Therefore, it is believed that a magnesium-rich diet can help you manage and avert type 2 diabetes. However, we still need concrete research on it.
- Another benefit of taking magnesium for sleep is that it reduces symptoms of headaches and migraines. However, the dosage required for migraine treatment is much higher than the standard magnesium dosage for sleep. Hence, you should only take it for migraines under a doctor’s supervision.
While nothing has been concretely established, early studies indicate the positive effects of magnesium, especially on our sleep.
