Body water (consisting of water and important ions) makes up 60% of body weight, so staying hydrated is extremely important, especially during the summer months. Drinking enough water will help you deliver nutrients to your cells and keep your organs functioning properly. For blood donors, drinking enough water is essential for a successful donation and for keeping the body healthy.
1. Why is rehydration necessary when donating blood?
The blood in our body consists of two main components, blood cells and plasma. Because plasma is 90% water, if the amount of water in your body is not enough, it will affect the amount of body blood. In addition, blood volume is directly related to the body's activities such as when you lose a lot of sweat, or lose water, the amount of blood may decrease due to being concentrated. Water helps blood flow, so when you're well hydrated, you'll feel less dizzy during the donation process. During blood donation, if you become dehydrated, your blood pressure may drop, leading to dizziness.
After donating blood, the body is at risk of dehydration because water is lost in the donated plasma, so it is necessary to rehydrate.
2. How to rehydrate before and after blood donation?
2.1 Before donating blood:
- Add more water at night and in the morning, drink at least 8 glasses of water.
- Pay attention to the body's signs of dehydration such as: thirst; feeling dizzy or lightheaded; tired; Dry mouth; lips or eyes; urinating less and/or urinating dark in color so that water can be replenished in a timely manner. Carrying a water bottle with you is a great way to make sure you never get dehydrated. It serves as a reminder that you need to drink water no matter where you are or what you are doing.
2.2 After donating blood:
- Drink plenty of water within 24 hours, as it helps to replace the lost fluid and also helps prevent a drop in blood pressure.
- Along with nutritional supplements, blood donors should avoid drinking alcohol on the first day after blood donation and eat iron-rich foods to compensate for iron and make blood.
