Lesson-541 关于献血，这些你千万要了解
*
Save lives from the comfort of a chair? Give blood and it's possible. You can usually donate if you're healthy, 110 pounds or more, at least 17 years old.
Before you go to your local blood bank, have a light meal, drink plenty of water, write down any medications you're taking, bring two types of IDs.
*
When you arrive, the staff registers you. You answer some health questions. Bonus, you get a quick checkup. When you donate, you sit or lie back in a chair, and a staff member cleans part of your arm. She draws a pint of your blood with a sterile needle, then puts a bandage on you. It may take only 10 minutes.
Afterward, you get a snack and a drink. You might be able to leave 10-15 minutes later. To feel your best the rest of your day, drink lots of water. Skip tough chores or heavy lifting for 5 hours.
*
Call your doctor if you feel nauseous, dizzy, or lightheaded after you rest, eat, or drink; have a bump, bleeding, or pain when you take off the bandage; feel ill with cold or flu-like symptoms within 4 days.
