Abstract
Poor nutrition can cause us to not ingest several necessary vitamins, minerals, and essential acids, and lack of one or more of these will negatively impact our sleep. The solution is as easy as determining if we’re missing any of them, then ingesting them via food or supplements.
Here’s what I learned from recently making good progress with the chronic sleeplessness I've had for more years than I can remember. Most nights I’d get perhaps 3 hours of sleep per 24 hour period, and that usually wasn’t continuous sleep. After reaching a point where I could no longer go on in this manner, I did research and I realized I had extremely low levels of the following vitamins, minerals, and other elements that are essential for sleep. Ironically, I actually thought I had been eating healthily for all these years. This isn’t a guaranteed cure all but it’s worth exploring, and they’re incredibly easy and inexpensive fixes to implement
Salt
In my efforts to avoid high blood pressure I ended up ingesting far too little sodium, which can seriously disrupt sleep. I stopped eating processed foods a few years ago after I realized with horror that I was ingesting 9,000 mg of sodium (not salt, but sodium) daily. Unbeknownst to me, I probably needed most of it due to heavy sodium loss from weightlifting, cycling, etc. Now I add 10 g of salt into my food each day, and that seems to be the right amount for me based on how my sleep is improving. I live in America, where given our diet hyponatremia (eating too little salt) would never occur to most doctors as a possible reason for sleep issues.
If you happen to eat too little salt, just add more to your food. Nothing could be easier.
Magnesium
Magnesium helps improve sleep by calming the nervous system, relaxing muscles, and regulating melatonin. Physiological effects on sleep include:
- Nervous system relaxation: Activates GABA receptors to quiet brain activity and reduce stress.
- Hormone regulation: Helps lower cortisol levels and supports natural melatonin production to maintain the sleep-wake cycle.
- Muscle function: Relieves physical tension and helps prevent nighttime leg cramps.
You can easily fix low magnesium by taking a supplement, or eating foods high in magnesium (which is the best way to absorb vitamins and minerals).
B Vitamins
In particular, Vitamin B6 (Pyridoxine) assists in converting tryptophan into serotonin and melatonin. Deficiencies can cause psychological distress or insomnia, while balanced levels improve overall sleep quality. Vitamin B12 (Cobalamin) influences circadian rhythms and melatonin suppression. Correcting a deficiency can normalize sleep-wake cycles, but high levels or evening doses can trigger alertness and wakefulness.
Taking a B complex supplement (containing all the B vitamins) or eating foods rich in B vitamins is the fix for this deficiency.
Essential Amino Acids
There are 9 amino acids considered ‘essential’ because the human body can’t make them from other components as it can with the other 11 amino acids. That means if we don’t ingest enough essential amino acids we are guaranteed to experience a range of negative effects, many of which will likely impact our sleep. Tryptophan is the main essential amino acid related to sleep, and is a necessary component to making serotonin and melatonin, which most of us are familiar with as being crucial to relaxation and sleep.
The good news is a single scoop of whey protein (about 30 grams, depending on the manufacturer) is enough to provide all the essential amino acids you need, even if you’re highly active.
These are some areas I recommend you look into if you’re suffering from chronic sleeplessness. Given the constant stress we trauma sufferers endure and the fact we often don’t take proper care of ourselves, we could easily be worsening our sleep issues via a lack of proper nutrition.
I arrived at these conclusions via my own research and experimentation because I’ve yet to meet a doctor I thought capable of sussing out a complex issue like this (doctors in the US medical system are harried by administrators and fearful of lawsuits, so I know that affects their ability to properly diagnose issues). However, you can get a blood screening to assess your sodium, magnesium, and other factors to see if low levels may be contributing to your sleep issues. I hope this helps.
