Does sub-health include insomnia and dreaminess? What could it be?

Does sub-health include insomnia and dreaminess? Can I eat ginsenoside Rh2? Insomnia and dreaminess are a manifestation of sub-health. Many people's physical function declines due to the pressure of work. As soon as I go to bed at night, I worry that I can't sleep, forcing myself to fall asleep as soon as possible, and the result is counterproductive. Sometimes I wake up after falling asleep for an hour or two, and then I fall asleep again after a long time and have many dreams. The more afraid of insomnia, the more excited brain cells are, and the more difficult it is to fall asleep. To deal with insomnia and dreaminess, you can choose some drugs that can improve immunity and resist fatigue. For example, ginsenoside Rh2 is a natural active ingredient extracted from ginseng, which can balance the immune system and improve the activity of immune factors such as immunoglobulin. The higher the content, the better the effect.
