Can I take a shower after having my blood drawn?

Nowadays, more and more people are donating blood for free. When donating blood, they all have to go through the step of having their blood drawn. In addition, if you go to the hospital for treatment due to illness, you also need to undergo a blood test to determine the patient's condition, and blood samples need to be drawn from the patient before the blood test. After having blood drawn, there are many things to pay attention to. So, can you take a shower after having blood drawn?

1. Can I take a shower after donating blood?

You can take a shower. Many people think that they cannot take a shower after having their blood drawn, mainly because they are worried that the skin will be damaged and dirty water will enter the body after taking a shower, causing infection. But in fact, the needle hole for blood drawing is very small, and if you avoid directly washing the wound with water when taking a bath, the chance of infection is very small.

2. How long should I wait to take a shower after having my blood drawn?

It is best to take a shower after 26 hours. Blood drawing has no substantial impact on your health. You can take a shower about an hour after the bleeding stops, but just avoid getting wet.

If it lasts more than 6 hours, the puncture wound will basically close. At this time, even if it is washed with water, it will not cause wound infection as long as it is not rubbed hard. So if you are worried, you can wait 6 hours after blood draw to take a shower.

3. What should you pay attention to when taking a bath after blood drawing?

1. Fasting. It is best not to eat high-protein or greasy foods or drink alcohol the day before blood collection, because these foods and alcohol will directly affect the proportion of blood components, which in turn affects the test results.

2. On an empty stomach. Because the content of substances in a person's blood changes after eating, it is difficult to obtain stable test values ​​after drawing blood on a full stomach. Experts require that the subjects should fast for more than 10 hours from the night before to the next morning. During this time, various chemical substances in the human blood can reach a relatively stable state, ensuring the accuracy of the test results.

3. Relax. If a person is too nervous, it will cause blood vessels to constrict, making blood drawing difficult, so you should keep relaxed when having blood drawn during a physical examination.

4. To avoid bleeding from the needle hole. After drawing blood, you need to press with a medical cotton swab for three to five minutes. Never rub it with your hands, otherwise it will cause subcutaneous hematoma. If there is bleeding after compression, the compression time should be prolonged.

5. If you experience the following symptoms after blood drawing, including dizziness, blurred vision, and weakness, you should lie down immediately and drink a small amount of sugar water. Wait until these symptoms are relieved before continuing the physical examination.

6. If congestion occurs at the site of blood drawing, it can be improved by gently applying a hot towel one day later.
