A crisp, cool pool is a respite from the stress of every day life, offering a tranquil space to improve your cardiovascular health and muscular strength. Chronic nausea while swimming is distracting and hardly refreshing. If symptoms don't go away with basic lifestyle changes, you may need to visit your health care provider to determine the cause of your queasiness.
Dehydration is a common cause of nausea in all forms of exercise. Being surrounded by water may make you less aware that you are becoming dehydrated. Its crucial to drink water before, during and after exercise to keep your body properly hydrated. Nausea Help recommends drinking 16 ounces of water two hours before you exercise and another 16 ounces 20 minutes before you exercise. You should also keep a bottle of water near the side of the pool so you can take a few gulps every 10 to 15 minutes.
If you also have a headache present with your nausea, you may be suffering from swimmer's headache, also known as supraorbital neuralgia. According to the National Center for Biotechnology Information, ill-fitting swimming goggles may be to blame. To prevent water from leaking in, swimmers might over-tighten their goggles, putting excessive pressure on the nerves of the scalp. It may help to use goggles made out of a softer rubber with a looser fitting strap.
Hypoglycemia -- low blood sugar -- occurs when your body's blood glucose level is too low, usually as a result of not eating enough before exercise. This is an especially common symptom in individuals with diabetes. While you can also make yourself feel sick by eating right before or during exercise, it's generally safe to eat a small meal containing lean protein, complex carbohydrates and healthy fat about an hour before exercise. If you have a larger meal, wait two hours.
Sweets and Sweat
It's natural to want to push your limits during exercise to reach a new fitness level, but overdoing it can lead to exercise-induced nausea, according to Fit Sugar. Overexertion may also lead to light-headedness. If you've been pushing yourself especially hard, slow down and let your fitness level build gradually.
Eating candy or drinking soda right before you exercise can cause you to feel nauseous and fatigued, according to Nausea Help. As with other foods, wait at least an hour before exercising if you've been indulging in sugary treats.
