1. Low potassium
If your headache is after a workout then you most likely need potassium.
2. Sinus pressure
Usually caused by allergies or sickness.
1. Low potassium
Celtic salt in water, or some frut with potassium (banana, mangos).
2. Sinus pressure
For allergies you can meditate to relieve sinus pressure (focus on the location and tell you immune system to stay calm) or for both you can take a
hot shower, sip hot tea with lemon.
3. Peppermint oil
Apply a small amount of peppermint oil to your forehead and it will feel like icey hot to relax you. (some people say to never use essential oils on your
skin but I don't believe it is an issue unless done in large quantities excessively).
