Why This Happens / Why It Matters

Mechanisms of Exercise-Induced Nausea

Nausea during exercise can occur due to reduced blood flow to the stomach as blood is redirected to muscles. This can slow digestion and lead to discomfort. Additionally, intense physical exertion can stimulate the vestibular system and the brain's vomiting center, contributing to nausea.

Research-Backed Key Points

  • A 2020 study in Sports Medicine found that dehydration increases the risk of exercise-induced nausea.
  • According to research published in the Journal of the International Society of Sports Nutrition, eating too close to workout times can exacerbate feelings of nausea.
  • A meta-analysis of exercise studies indicated that gradual acclimatization to workout intensity reduces the likelihood of nausea.

Practical Tips

  • Hydrate Properly: Drink water throughout the day and consider consuming an electrolyte drink during longer workouts.
  • Mind Meal Timing: Eat a light meal or snack at least 1-2 hours before exercising.
  • Pace Yourself: Start with a warm-up and gradually increase the intensity of your workout.
  • Avoid Heavy Foods: Steer clear of high-fat and high-fiber foods before exercising.

Common Myths or Mistakes

  • Myth: Eating immediately before a workout provides energy.
    • Fact: This can lead to gastrointestinal distress and nausea.
  • Mistake: Ignoring hydration needs.
    • Fact: Dehydration is a major cause of nausea during exercise.
