Rest Well
You must get plenty of rest when you have the stomach flu so that the body can fight off the infection quicker. Reduce the amount of activity you do and rest more so your immune system can have a chance at fighting off the viral infection and repairing damage on the cellular level. The importance of rest can not be overemphasized, not just when one is ill but also in your daily life. Having enough and regular sleep are remedies and preventive measures to take to avoid sickness like stomach flu.
Acupressure
Acupressure involves using the fingers, palms or elbows to apply pressure to acupoints in the body. Acupressure has been shown to be effective in treating nausea [3] and also to relieve vomiting. Specifically, the pressure point P-6 can be found by measuring the width of three fingers down from the bottom of the palm. Gently massage this spot, and you are sure to feel relief from the pain.
