捐血痛不痛?難不難?
捐血針頭穿刺皮膚時會有瞬間刺痛，一旦穿過皮膚並固定就不痛了，和打針類似。
捐血前有哪些事項要留意?
(1) 不宜空肚捐血，否則可引起頭暈等不良反應；
(2) 捐血前喝適量飲料，可避免捐出的血液過濃；
(3) 捐血前一晚應有充足睡眠。
捐血會令身體變虛弱嗎?
血液的收集量是根據捐血者體重來決定的。一般45-50公斤者可捐血350毫升；50公斤或以上者可捐血450毫升。人體內的血液約有一半是水份。所以，當您捐出350毫升的血液時，其中有180毫升是水份。對健康人來說，造血器官生產足夠的血液來維持日常生活是輕而易舉的事。正常人的造血系統每時每刻都在製造血液細胞，以替代不斷代謝的血細胞。
捐血後多久才可做運動?|
捐血後稍用力壓迫針孔處5分鐘止血，休息10-15分鐘後即可活動，如須劇烈運動或提取重物者，建議在24小時後進行，以免造成瘀血。

What do donors need to be aware of before blood donation?
(1) Do not have an empty stomach before donation. Otherwise, donors may feel dizzy
(2) Drink sufficient liquid before blood donation to avoid the blood being too concentrated.
(3) Have a good sleep the night before.
Will donors become weak after donating blood?
The amount of blood collected is based on the body weight of the donors. In general, donors weight about 45-50kg can donate 350ml of blood, while 50kg or above can donate 450ml of blood. About half of the human blood is made up of water. Thus, among 350ml of blood donated, 180ml of which is water. For healthy people, it is easy for blood-making organs to produce sufficient blood to maintain their daily lives. The blood-making organs are producing blood every second to replace the dead blood cells.
After donating blood, how long should one need to wait before doing exercises?
After donating blood, press the venepuncture site with the finger lightly for 5 minutes to stop bleeding. After taking a rest of 10-15 minutes, one may resume normal activities. However, it is advised that one should do strenuous activities or carry heavy items after 24 hours to avoid blood stagnation.
