How a Lack of Sodium Impacts Our Sleep

Sodium, that substance we were wrongly taught to avoid, is actually key to getting a good night’s sleep. Who knew?

Sleep is critical to leading a long, healthy life. If your sleep is disturbed, or you for some other reason are not getting adequate rest, there will be negative cognitive, immune and other long-term consequences. The problem is, as we get a bit older, we tend not to sleep as well. As a 20- or 30-year-old, I could sleep straight through pretty much anything with no real effort on my part. I could just lie down and wake up 8 or 9 hours later. Now I need to pay attention to how I am preparing for sleep, what my sleep environment is, the temperature, the sounds, and a host of other factors that could have me not falling asleep or waking up in the night, which I find quite annoying.

Sodium, that substance we were wrongly taught to avoid, is actually key to getting a good night’s sleep. Who knew? It turns out that when our sodium levels fall, our adrenals try to compensate by increasing adrenaline. That is because adrenaline helps our bodies retain sodium. But as you can imagine, having increased levels of adrenaline is not really what we want to get a good night’s sleep. Then there is the bathroom factor. Being low on sodium impairs the release of antidiuretic hormone, ADH. This is the hormone that helps you sleep through the night without waking up to pee every 2 hours. Sodium helps maintain your ADH levels through the night. Being low on sodium, you could have a less than restful night of multiple bathroom visits and anxiety; not something I would look forward to. 

One of the things I have noticed when using LMNT in my water, is that my visits to the bathroom, day or night, are greatly reduced. I now make a nighttime visit maybe once or maybe not at all in the night. This is something I hadn’t really considered until I started adding LMNT to my water. Most of us, unless we are eating a ton of processed foods, and you know you should not in any way be doing that, are daily not getting enough sodium, and probably not enough magnesium or potassium either. First thing when I wake up in the morning, I have 20 oz of water with LMNT. This will immediately rehydrate my body and give me these essential minerals. Being the chilly season, I have also been into having a salty sugar-free hot chocolate using LMNT chocolate salt mix. Yum.

  1. So…this is basically an ad masquerading as “facts”. On social media, people are encouraged to be open about paid placement. This should be clearly marked as an ad. Sodium may be important for sleep, but I’d never accept that as fact based on this advertisement.
