Lying down after a meal can cause acid reflux, indigestion, and bloating. The digestive system needs time to process the food while the body is upright.
Tea contains tannins and coffee contains caffeine — both can interfere with iron absorption and slow digestion. Drinking them right after meals can also cause acidity.
Showering increases blood flow to the skin and limbs, reducing blood flow in the stomach, which weakens digestion and may cause stomach discomfort.
Fruits digest very quickly. When eaten immediately after a heavy meal, they ferment in the stomach, causing gas, acidity, and bloating. It’s better to eat fruits 1–2 hours before or after meals.
Smoking after a meal greatly increases absorption of nicotine and harmful chemicals. It is said to be 10 times more harmful than smoking at other times.
Drinking too much water right after food dilutes stomach acids and slows digestion, causing bloating and heaviness.
Running, gym workout, or heavy activity right after eating can cause cramps, vomiting, and indigestion. Mild walking is okay, but avoid intense movement for at least 45 minutes.
