Simple vocal tics consist of sounds that do not form words, such as: throat clearing, grunting, coughing, and sniffing. The DSM-IV divide tic disorders in three main categories: transient tic disorders, chronic motor or vocal tic disorder and Tourette disorder.
If you are healthy person who has been exercising regularly, after you donated blood, you wonder whether you can exercise right after that. The answer is no. You should only exercise after at least 5 hours of resting. Do not run, swim, do weight training or other rough movements during the first 5 hours of donation. In fact, even after that period, your competitive performance in the court or track may be affected.
This is more common for younger people and for people who are donating for the first time. If you have fainted after donating blood and you choose to donate again, be sure to tell the person who is going to draw your blood. Drinking extra water before you donate may reduce this risk. What tests are done on donated blood? After donation, your blood is tested for certain diseases, such as hepatitis B and C, HIV, West Nile virus, and HTLV-I/II viruses. Donated blood must pass all of these tests. If any disease is detected, the blood is thrown away and the donor is notified. The blood is tracked so it can be traced back to the donor and the collection location.
