Why does sustained exercise sometimes make me very unwell for hours or even days? I lift heavy weights at the gym three times a week with no problems, I get enough sleep, I eat very healthily (but perhaps my intake is low on carbs like bread, pasta or rice). But every now and then, when I do a sustained cardio type exercise for about an hour or a little more (playing a sport, taking occasional breaks for water, etc), I start to feel fatigued before everyone else does, then I feel extremely sick to the point of having to sit down, not wanting to move. In extreme cases, I've been unwell for more than two entire days after.
