Nausea is an unpleasant feeling, especially during exercises such as running. There may be several reasons you are feeling queasy as you run, and they can be addressed easily. If you continue to feel nauseous, talk with your doctor or a trainer about possible underlying reasons.
Step 1
Avoid running before you have eaten breakfast. According to Stew Smith, a military fitness trainer, when you work out pre-breakfast, your body is running on the last meal you had, which likely was at least 10 hours ago. Without fuel, you can feel dizzy and nauseous.
Step 2
Keep hydrating. Marathon Training states that dehydration is the top reason runners feel nauseous. Sip fluids frequently during running. Gulping too much liquid at once can cause an uncomfortable, full feeling.
Step 3
Choose your eating times wisely. MayoClinic.com explains that, to prevent nausea, big meals should be eaten at least three to four hours prior to running, small meals two to three hours before exercising and small snacks an hour before running. Good snack choices include a granola bar, peanut butter crackers, a banana or an energy bar.
Tips and Warnings
- Find foods that work for you before and during your workouts. If you want to try a new energy gel or snack, do it on a practice day, not the day of a race, to avoid any unpleasant surprises.
- If you keep experiencing nausea, talk with your doctor about your symptoms, to ensure there are no underlying reasons for your discomfort.
