Sleep & the Immune System


There are a plethora of benefits that come with a good night of sleep. In contrast, not getting enough sleep can lead to shorter attention spans, increased anxiety, weight gain, less effective immune systems and more. If you are one of the millions who have trouble falling and staying asleep, it may be time to try something more. 

In the article below, we dive into natural sleep aids and sleep-promoting supplements.

What is a natural sleep aid?

Sleep aids are products intended to help with insomnia, restless sleep, and other sleep-related issues. According to the National Institute of Neurological Disorders, approximately 40 million people in the U.S. suffer from long-term sleep disorders. Natural sleep aids help to alleviate these problems by utilizing ingredients without relying on the addition of synthetic medicine, which can be addictive and harmful to your body.

How do natural sleep aids work?

Sleep aids – specifically those that contain melatonin – help your body know when it’s time to go to sleep. Melatonin is a hormone produced by your brain in response to darkness. The more light registered by your brain, the more your brain will think it is time to wake up. 

This is one of the many reasons doctors are calling for people to “unplug” or disconnect from all devices at least 1 hour before bed. The main purpose of many sleep aids is to help the brain to slow down the nervous system and prepare for sleep.

Why Not Prescription Sleep Aids?

Since we are not your doctor, we cannot say you should or shouldn’t take prescription sleep aids. While sleeping pills work fast and well, sleeping pills can come with a ton of side effects including dependence, memory impairments, and even depression.  

What Should I look for in a sleep aid?

For natural sleep aids, it’s important to understand the different leading ingredients in most natural sleep aids.

  • Melatonin
    • Melatonin is a hormone secreted from the pineal gland that, put plainly, helps your brain understand that it’s time to sleep. The pineal gland, which is inactive during the day, is flipped on at night by the suprachiasmatic nucleus and starts producing melatonin before releasing it into the blood. 
  • Valerian Root
    • Valerian root has been used to promote sleep for centuries. It works by inhibiting the breakdown of gamma-aminobutyric acid (GABA) in the brain leading to feelings of calmness and restfulness. In contrast, low Gaba levels have been shown in relation to elevated stress, anxiety, and insomnia.
  • Magnesium
    • Low magnesium has been directly associated with heightened anxiety, stress and more due to its healthy GABA level maintaining characteristics. Knowing this, it’s no surprise that proper magnesium levels will help promote deeper and higher quality sleep along with a variety of other stress-relieving benefits.
  • Passion Flower
    • Similarly to Valerian Root and Magnesium, Passion Flower has been known to increase gamma-aminobutyric acid (GABA) levels in the brain.
  • L-Theanine
    • In addition to its GABA boosting characteristics, L-Theanine enhances alpha brain wave activity which is present during REM (Rapid Eye Movement) sleep. L-Theanine works to relax the brain without the sedative effects.

What shouldn't be in a natural sleep aid?

Typically, an all-natural sleep aid will brand itself as such making it much easier to separate from the synthetically-based version. If you’re unsure of what it is you’re looking at, flip the box over to the ingredients and keep an eye out for some of the following ingredients.

  • Diphenhydramine
    • Diphenhydramine is an antihistamine commonly found in medications like; Tylenol PM, Advil PM, Aleve PM, ZzzQuil, Benadryl, and more. Diphenhydramine gets its sedative effects by allowing histamine to build up in the gaps between nerve cells called synapses.
  • Doxylamine Succinate
    • Doxylamine succinate, which can be found in products like Unisom, is an antihistamine that works to block chemicals like histamine and acetylcholine in the brain. By doing so doxylamine succinate acts as a sedative, promoting deep sleep and treating symptoms for allergies and colds.
