ELI5: Why do migraines make you nauseous ?
gpt
There are theories about how the vagus nerve is responsible for the nausea. Breathing techniques have proven effective in reducing it. Try 7-12 (practice when you can): Breathe in for about 7 seconds and out for 12. on outbreath you may have to purse your lips to slowly deflate. Imagine the last of the air going out through the soles of your feet until the diafragm is completely relaxed / belly empty of air. It also lowers heart rate and bp, releases endorphines and adjust the balance between O2 and CO2 in the blood. Simultaneously you can use your fingers to press from both sides on the meaty area between the thumb and index finger. It’s supposed to hurt a bit. This alone reduces nausea.
