We got a above ground pool and had them dig a hole so the pool could go under 2 feet. Well they didn't put the sand back because my hubby says he was going to do it. Soo I thought to be helpful I would go and start refilling the space a long the side of the pool! Why did I do that ..... I started seeing stars- felt like I was going to faint after 30 min in the sun doing it and my arms feel like jello! Talk about being out of shape!!!! Wonder how many calories I burned?

There are some good websites to convert activity to calories! I started back swimming this week, I do breast stroke and side stroke laps with webbed gloves. oh my gosh, i can barely move my arms! Yikes I am out of shape too!

Of course your light-headedness could be due to overexertion in the sun. However, are you on blood pressure medication? I was very light-headed shortly after surgery and when my PCP cut my blood pressure meds in half, it helped a lot. Then my PCP took me completely off my BP meds and it went away altogether.

I think I had only lost around 20 pounds when I was taken off the BP meds. I was pretty shocked that my BP got back to normal with such a small weight loss.

I worry about dehydration. Nutritionist says we need more liquid with heat and excercise. I've had same issues too. Just light headed...she said to try ice Water with a small amount of orange juice.

Nope never had hbp. I think it was the heat and not properly hydrated. Went swimming today with the kids- couldn't get much exercise cause they followed me all over the pool! I'm sure I probably burned a little bit of calories.

I'll try that next time... Just doesn't seem like you could ever get enough water in this heat. I'm in south Florida!

There are a lot of things that can cause light-headedness, but the big ones related to weight loss are too little water, too little protein, and depletion of electrolytes (which are also lost in sweat): potassium and sodium, primarily. Fitness drinks exist for a reason, and so do protein supplements. Take care out in that heat, folks!
