When you push your body hard during a cardio workout, especially if you are running or trying to lose weight, you might expect to feel tired, sweaty, and out of breath. These are normal reactions. But sometimes, your body sends signals that are not so obvious. These unexpected symptoms could be warnings that something is not quite right.
One common surprise is chest tightness or pain during or after running. While mild discomfort can happen due to heavy breathing or muscle strain, severe or lasting chest pain should never be ignored. It could be a sign of something serious, like a heart problem. If the pain spreads to your arms, neck, jaw, or back, or if it comes with shortness of breath, dizziness, or nausea, it is important to stop and seek medical help right away https://int.livhospital.com/heart-discomfort-after-exercise-10-common-causes-and-when-to-seek-help/.
Another warning sign is extreme fatigue that does not go away after rest. If you feel unusually tired during a normal cardio workout, or if you are losing weight but feel weak and drained, it could mean your body is overworked. Overtraining can cause persistent muscle soreness, trouble sleeping, and even frequent colds. These symptoms show that your body needs more recovery time https://pliability.com/stories/signs-of-overtraining-running.
Some people notice their heart rate acting strangely during or after exercise. A rapid or irregular heartbeat, especially if it does not settle down quickly, can be a red flag. If you feel your heart pounding, skipping beats, or racing for no reason, it is best to slow down and check with a doctor https://thehealthcareinsights.com/fitness-red-flags/.
Running and other intense cardio workouts can also trigger symptoms like dizziness, cold sweats, or nausea. These are not normal and could mean your body is struggling to keep up. If you feel faint or sick during a workout, stop immediately and rest. If the symptoms continue, get medical advice https://mycardiologist.net/chest-pain-after-exercise-causes-and-solutions/.
Even if you are trying to lose weight and feel proud of your progress, pay attention to how your body feels. Unexpected symptoms during a cardio workout are not just signs of hard work-they could be your body’s way of asking for help.
