This is because all three ingredients act on the stomach and help you to deal with the after-effects of a hangover.⁠ ⁠ Bananas are easy to digest and are also known to calm stomach upset and hydrate the body. Alcohol dehydrates the body, which is why you feel dizzy and have headaches. Bananas are also rich in electrolytes and minerals such as magnesium and potassium, which are severely depleted due to heavy drinking.⁠ ⁠ If honey is added to banana milkshakes, it helps build up the depleted blood sugar levels, providing some energy. And adding milk to it soothes and rehydrates the digestive system post-heavy drinking.⁠ ⁠ ⁠ ⁠ #banana #milkshake #honey #hangoverdrink #hangovercure #hangover #science
