Feeling lightheaded and/or dizzy, as when you’re about to pass out, aren’t normal reactions to exercise.
After an aerobic activity session, you should feel invigorated, not totally wiped out.
Your description sounds as though you are working extraordinarily hard.
Do you eat anything before your exercise? Are you drinking during your run or bicycle ride? How is your overall fluid intake?
Although an exact diagnosis based on your description cannot be given here, these few suggestions may help avoid these feelings
• Be certain to eat a snack before exercise. If you’ve less than one hour before your session, fewer than 200 calories is recommended. A piece of fruit and a couple of crackers work well for quite a few people .
Your snack may be a bit bigger if you have two hours or so until your workout begins – one small plain bagel with jam, a piece of fruit and a yogurt, or two or three fig bars and a cup of milk or juice.
• Drink 16 oz. of fluid 2 hours before an event. This promotes hydration and authorizes enough time to excrete any excess liquid.
• Drink fluids during exercise. Weighing yourself before and after exercise can help determine your sweat rate, and how much you’ll need to drink.
o When you lose 1 lb. per hour – drink 4 oz. every 15 min
o When you lose 2 lbs. per hour – drink 8 oz. every 15 min
o When you lose 3 lbs. per hour – drink 8 oz. every 10 min.
o When you lose 4 lbs. per hour – drink 10 oz. every 10 min.
• If you are exercising for longer than 60 minutes, add some fuel to your water with a sports drink.
These fluid replacement drinks include glucose and electrolytes (sodium and potassium) to help with fluid intake and absorption.
Talking with your healthcare provider is a good idea when these strategies do not help.
Being properly fed and hydrated, in addition to getting enough rest and watching your breathing as your exercise, ought to help make your workouts more productive.
