Reasons You Might Not Be Able to Donate Blood
Donating blood is a generous — not to mention necessary — act, but there are several restrictions on giving that protect you and future recipients of your gift
The medications you're taking
Most medications won’t disqualify you from being able to donate blood. 1.. If you're taking an antibiotic for an infection, you may be asked to wait until you're healthy again; if you're taking aspirin and donating platelets, you must wait two full days after taking aspirin or any medication containing aspirin before donating,
You’ve tested positive for hepatitis or HIV
2., you cannot donate if you’ve tested positive for either condition. Because some types of hepatitis may not be treatable and can lead to fatal health problems, such as liver failure and liver cancer, it is too risky to donate blood if you have these diseases.
3.
If you weigh less than 110 pounds, you're not eligible to donate blood. Underweight individuals tend to have low blood volumes and therefore may not tolerate the removal of the required volume of blood.
Your iron levels are too low or too high
Having low iron — less than 12.5g/dL for women and 13.0g/dL for men — will disqualify you from donating. For this reason, frequent donors, especially women, are encouraged to take iron supplements and eat iron-rich foods to keep their levels in the normal range. 4..
You recently got a piercing or electrolysis
5., if you've recently gotten an ear or body piercing or electrolysis with a reusable gun or reusable instrument. Before you get a piercing or electrolysis, he recommends doing your research on whether the place employs single-use equipment.
A.Having levels that are too high will also disqualify you from blood donation
B.High blood iron levels increase the risk of diseases
C.But some may require a waiting period after your final dose
D.Since HIV and hepatitis can be transmitted through blood
E.You're underweight
F.When you go donate, make sure you have an updated medication list with you
G.You'll have to wait three months before you can give blood
Online programs to fight depression are already commercially available. While they sound efficient and cost-saving, a recent study reports that they're not effective, primarily because depressed patients are not likely to engage with them or stick with them.
The study looked at computer-assisted cognitive (认知的) behavioral therapy (CBT) and found that it was no more effective in treating depression than the usual care patients receive from a primary care doctor.
Traditional CBT is considered an effective form of talk therapy for depression, helping people challenge negative thoughts and change the way they think in order to change their mood and behaviors. However, online CBT programs have been gaining popularity, with the attraction of providing low-cost help wherever someone has access to a computer.
A team of researchers from the University of York conducted a randomized (随机的) control trial with 691 depressed patients from 83 physician practices across England. The patients were split into three groups: one group received only usual care from a physician while the other two groups received usual care from a physician plus one of two computerized CBT programs. Participants were balanced across the three groups for age, sex, educational background, severity and duration of depression, and use of antidepressants(抗抑郁药).
After four months, the patients using the computerized CBT programs had no improvement in depression levels over the patients who were only getting usual care from their doctors.
"It's an important, warning note that we shouldn't get too carried away with the idea that a computer system can replace doctors and therapists," says Christopher Dowrick, a professor of primary medical care at the University of Liverpool. "We do still need the human touch or the human interaction, particularly when people are depressed. "
"Being depressed can mean feeling lost in your own small, negative, dark world," Dowrick says. Having a person, instead of a computer, reach out to you is particularly important in fighting that sense of isolation. "When you're emotionally fragile, you're even more in need of a caring human being," he says.

Facebook lets friends connect. They can give each other updates, share photos and post comments. But that’s not all. Facebook might also stress users out.
In a new study, 88 volunteers how much time they spent on Facebook and the types of Facebook posts and comments that they made. In addition, they answered questions about their feelings and state of mind. They also offered saliva. Researchers tested it for cortisol. This chemical is a stress hormone. Levels of it vary throughout the day.
In this study, people with the most Facebook friends, more than 300, had somewhat higher cortisol levels. Additionally, the more Facebook friends that users had, the more likely they were to feel anxious. On the other hand, youths who gave lots of ''likes'' and supportive comments on Facebook had lower cortisol levels. ''The more social support you give to others, the lower your stress hormone levels will be, '' says Lupien.
''This research decidedly combines the social science approach and the medical science approach on an important question in our social-media age, '' says Wenhong Chen, a sociologist at the University of Texas at Austin. ''It's ready pleasantly new to see Lupien’s team study cortisol levels-along with questionnaire data. ''
One finding from Lupien's work surprised Chen. Teens who felt they got a lot of support from others also had higher cortisol levels. Usually, she says, those feelings should protect people from stress. ''There are many potential dangers of social media use among young people, '' Chen notes. So, she says, enjoy Facebook, but be aware of the risks.
Lupien suggests that teen Facebook users share information with and support their friends on the site. They shouldn’t just stay silent. ''if anyone is more stressed, it's the watchers, not the sharers, '' she says. Also, she recommends that people who use social media heavily should find time to take active walks, to run or to do other activities. Cortisol increases a person's energy. “The best way to reduce stress hormones is to use the energy, '' she says.
