Feeling sick after a workout is frustrating, especially when working hard to improve your fitness. Throwing up or feeling nauseous after exercise isn't uncommon, but understanding why it happens can help you prevent it.

Various factors contribute to this problem, including:

• What and when you eat,
• Hydration,
• Stress levels and even
• Your workout intensity.

Let's explore the reasons behind post-exercise nausea and what you can do to stop it from happening.

Low Blood Sugar

One of the main reasons people feel lightheaded or nauseous during exercise is low blood sugar, also known as hypoglycaemia.

If youre working out without eating, especially first thing in the morning, your body might run out of fuel to keep up with the demands of the workout. When blood sugar drops too low, dizziness, nausea, and vomiting can occur. This is particularly true for anaerobic exercises like weightlifting or sprinting, which burn through glucose quickly.

Tips:

To avoid this:

• Eat a light meal about two to four hours before working out.
• Choose something easy to digest and high in carbs.
• Intake of moderate proteinlike oatmeal with a few nuts or a banana with peanut butter.
• Heavy, fatty foods as they sit longer in your stomach and might worsen nausea.

Dehydration and Overhydration

Both dehydration and overhydration can disrupt your body's fluid balance and cause nausea. When you are dehydrated, your body struggles to cool itself properly, complicating physical tasks.

On the other hand, drinking too much water, particularly during a strenuous workout, dilutes sodium levels in the blood, causing hyponatraemia. This electrolyte imbalance can cause nausea, headaches, and vomiting.

Tips:

• Stay hydrated by sipping water throughout the day, not just during your workout.
• Aim to drink when thirsty, but avoid guzzling large amounts simultaneously.
• If you're sweating heavily, consider adding an electrolyte drink to your routine. If it's too strong for your stomach, dilute it.

Wrong Food Choices

The food you eat before exercising significantly affects how you feel during your workout. When paired with physical activity, greasy, spicy, or dairy-heavy meals can upset your stomach. The body needs time to digest these foods, and exercising too soon after eating them can lead to nausea or vomiting. Artificial sweeteners and sugar-laden snacks can also be tough on your gut and cause discomfort during workouts.

Tips:

• Find out the effects of different foods on your health.
• If certain pre-workout meals make you feel ill, try adjusting the portion size or choosing something lighter, like a small serving of yogurt or a slice of whole-grain toast with almond butter.

Everyones digestive system is different, so find what works best.

Motion Sickness

Motion sickness can strike even during a workout! Exercises that involve a lot of movement or changes in direction, like high-intensity interval training (HIIT) or cycling, can sometimes confuse your inner ear and lead to dizziness and nausea. This happens because your eyes, ears, and body send conflicting signals to your brain, similar to how you might feel when reading in a moving car.

Tips:

• Fix your gaze on a single point during certain exercises to help stabilize your balance and reduce nausea.
• If closing your eyes while exercising makes you feel worse, keep them open and focus on something stationary.

Overexertion

Pushing yourself too hard during a workout can burden your body and trigger nausea and even vomiting. When you work out at a very high intensity, your body struggles to send enough blood to both your working muscles and digestive system. As a result, digestion slows down, leading to feelings of nausea. Overexertion can also cause a spike in body temperature, making you feel lightheaded and queasy.

Tips:

• Listen to your body and avoid overexertion.
• Gradually build up the intensity of your workouts and take breaks when needed.
• If you start to feel nauseous, slow down, take deep breaths, and cool down before resuming activity.

Stress and Anxiety

Stress can significantly influence how your body reacts to exercise. When you're nervous before a workout, especially in a high-stakes event like a competition, your body produces stress hormones such as adrenaline and cortisol. These hormones prepare your body for action but can also upset your stomach, leading to nausea or vomiting.

Tips:

• Calm your nerves by incorporating relaxation techniques into your pre-workout routine, such as deep breathing or mindfulness exercises.
• Ensure you're getting enough sleep and managing stress outside of the gym.

Tips to Prevent Nausea During Workouts

Now that we've explored the reasons behind post-exercise nausea, here are some general tips to prevent it:

1. Eat Smart: Have a small, balanced meal before exercising. Focus on easily digestible carbs and lean proteins. Avoid heavy or fatty meals right before your workout.
2. Stay Hydrated: Drink water throughout the day and remember to sip during your workout. Consider an electrolyte drink to replace lost minerals if you sweat a lot.
3. Start Slow: Don't go all out immediately if you're new to exercise or trying a new workout. Let your body adapt to the increased physical demand by gradually increasing intensity.
4. Take Breaks: If you feel unwell, don't hesitate to slow down, rest, and cool off. A brief respite can occasionally be the deciding factor.
5. Pay Attention to Your Body: Be mindful of how your body is feeling. If certain foods or drinks consistently make you sick, eliminate them from your pre-workout routine.
6. Talk to a Doctor: If you frequently feel nauseous or vomit after exercise, consult a doctor to rule out any underlying health conditions, such as food allergies or blood sugar issues.

In a Nutshell

Making a few easy changes to your routine may usually prevent you from feeling sick or throwing up after a workout, which is definitely not nice. Whether it's changing your diet, drinking more water, or reducing stress, understanding the underlying reasons of exercise-induced nausea, and following the following measures will help you get back to enjoying your activities without any unpleasant interruptions. If you're still having problems, seek a healthcare practitioner's counsel to ensure everything is in order.
