The morning of the day my husband was planning to donate blood plasma, he was suffering a bad headache. He said he had drunk a lot of water the previous day and he was still drinking water in the morning, but headache was too bad and he gave up going to the blood donation. I suspected he drank too much water and the sodium levels in his body were too low. The condition can cause headache. I made a glass of Salted Lemonade, which was a quick substitute of Sports Drink, and told him to drink it. Guess what happened. After he drank it, his headache quickly disappeared. This is how I made the Salted Lemonade. I am sharing this recipe hoping this information might help someone.
