I used to be able to meditate when my brain was a bit clearer and it did a lot of wonders for my brain fog and mood. When my brain is too bogged down I don’t have the mental ability to meditate anymore so I tried to think of another way to reap its benefits. One of the major pathways that benefits from meditation is the vagus nerve or the 10th cranial nerve. This nerve connects much of the body to the brain and is the lead composer of the parasympathetic nervous system (rest and digest). The vagus nerve is 80-90% afferent (meaning leading towards the brain) and controls a large part of the immune response between our ears. Stimulation of the vagus nerve has also been found to activate the locus coeruleus which is the main nuclei for norepinephrine and controls a good amount of our vigilance and feeling of being “alert.” Normally, to install a vagus nerve stimulator you have to pay $40,000 and it is quite invasive, but some researchers have figured out how to render some of the same effects without surgery. I will show you how you can make your own Vagus Nerve Stimulator below. You want to stimulate the conchae (shown below) and you only want to stimulate your left ear because they have found cardiac effects of stimulating the right. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5807379/ Here is a recent study exploring this. Now I did email someone who has studied this and asked him how I could make one at home. He advised me to first check with my doctor, but then sent me this amazon link. https://www.amazon.com/Tens-Ear-Clip-Stimulator-headphone/dp/B01CRSF1GK/ref=sr_1_sc_1_a_it?ie=UTF8&qid=1512957591&sr=8-1-spell&keywords=ear+electrod&th=1 You can connect both of these clips to your left ear through a TENS unit (make sure you have the correct jack size when you buy one). Once you have both of these items you Can attach one clip to your “Tragus” and the other to your conchae. Both of these have nerves that connect to the vagus. To better understand these areas just use a simple google search to better understand these mechanisms. Once you have done this you can turn your TENS device all the way up to where you can feel the stimulation on your ear, but not too much to where you have pain. I do this twice a day for 30 minutes but you may want to start smaller. I have used this for several months now and it does help. Thought I’d share this as I am more than happy for all the information you guys have provided me (may be a repost but thought I’d share anyways).
