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.
Most people feel fine after donating blood. A unit of blood (500 ml) is less than a pint, and the average adult body contains 10 to 12 pints of blood. Your body makes new blood constantly, and the fluid you give will be replaced within hours. Eating a full meal within four hours before donating will help you feel strong after donating.
