Exercise is supposed to make your body healthier and make you feel better, but there are times when you finish a workout and feel clammy and nauseous. This is due to a number of factors, all of which can make fitness an unpleasant experience. By understanding the specific processes that your body undergoes while you work out, you can become more aware of how to handle the rush of hormones and your flu-like symptoms after an hour at the gym or a tough run.


The symptoms of hormone production and exercise-induced nausea can often masquerade as the flu. First of all, you might feel nauseous after your workout and may even feel the need to vomit. You might also feel faint and dizzy and need to sit down. While you won't actually have a temperature, you could find that you skin feels clammy to the touch, a sure sign that you've been exercising too hard without the proper nutrition, hydration or technique.

Human Growth Hormone

One of the issues that could be partially to blame for your flu-like symptoms while exercising is human growth hormone. HGH is secreted naturally when you exercise and is responsible for muscle tissue growth, bodily growth and collagen turnover. But the release of the hormone can make you feel nauseous, especially when combined with other exercise factors. Because you can't control the release of HGH and because HGH is actually beneficial to your body, you need to learn to manage the symptoms properly.

Exercise-Induced Nausea

HGH is partially to blame for the phenomenon known as exercise-induced nausea. Even if you've never experienced the flu-like symptoms yourself, you might have seen it occur while watching your favorite fitness and weight loss television programs. Exercise-induced nausea can have a severe effect on your ability to exercise, but HGH isn't the only factor to blame. Along with hormones, dehydration, poor nutrition and even high blood pressure can all be to blame.

Treatment and Prevention

Your body releases HGH naturally and it's a beneficial process that makes exercise even more valuable. Exercising at high intensity over a long period of time, however, could release HGH levels that make you feel nauseous. Instead, try altering your workout patterns by interspersing bursts of high-intensity exercise with more moderate activities to monitor your flu-like symptoms.

Because nausea can also be the result of dehydration, aim to drink 7 to 10 ounces of water for every 10 to 20 minutes of exercise and make sure you eat a carbohydrate-rich snack before you hit the gym. Doing so tops up your energy reserves so you don't feel tired and sick while you work out.
