To prevent nausea, several practical measures can be taken:

• Eat small, frequent meals focusing on bland, protein-rich foods like chicken, beans, or peanut butter; avoid spicy, greasy, or strong-smelling foods.
• Stay hydrated by sipping small amounts of water regularly, and consider electrolyte drinks if vomiting occurs.
• Avoid carbonated and acidic beverages; drink liquids between meals rather than during meals.
• Maintain an upright posture after eating and avoid bending forward or crunching the abdomen to reduce stomach pressure.
• Get fresh air and avoid strong odors, which can worsen nausea.
• Try remedies like ginger or peppermint tea, cinnamon, or aromatherapy using lemon or lavender oils.
• Avoid eating quickly, lying down soon after meals, and wearing tight clothing around the waist.
• For motion sickness, face forward in the vehicle, avoid looking at side windows or screens, and keep eyes on the horizon.

Additional strategies include distraction techniques, controlled breathing, cool compresses, and wrist acupressure, though their effectiveness varies. If nausea is persistent or severe, consulting a healthcare provider is advisable for potential medications or further evaluation.
