Advice & Tips: Eat iron rich foods. Get plenty of fluids and rest. If you have low iron levels -- and -- low blood pressure keep legs elevated when possible. When sitting and standing for long periods blood tends to pool around your waist and upper thighs so it's important to help your body to regulate the blood flow. I learned this in Yoga and it was so interesting because I naturally have an inclination to put my feet up whenever possible. (In the car as a passenger I put them up on the dash, watching TV or relaxing reading a book or in social situations I look for anything with an ottoman or a couch where I can lay semi-reclined. (My friends know me well enough that it isn't a problem. If you are at a stranger's house or restaurant, put your feet on a rung of a chair not being used but I have also put my feet up on an unused chair at the table and explained to people (the waitress, people, etc.) why I need to do this. Also: I recumbent using "Vitalyte" for a great, low sugar, no colorants form adding to your water. It is in powdered form so you can control the amount you think is best for you.
