If the person is feeling faint, dizzy, or seasick, and is still conscious, help him or her to lie down at once. Raise the legs, loosen tight clothing, and put a cover on the person. Encourage him or her to relax and to breathe
slow, deep breaths. Have the person continue to lie down until proper face color returns. Shiatsu on acupoint (GV 26) above the center of the upper lip is helpful.
If twig tea with a teaspoon of soy sauce is available, let the person drink this.
An effective self-treatment is to open the mouth, then use the thumb to strongly press the roof of the mouth while the person exhales. This immediately affects the brain.
