There are many activities that may have serious and harmful additional psychological effects on people who are desperate and seeking extreme excitement. These activities are often very dangerous and should not be attempted. Here are some examples: 1. **Extreme dangerous sports**: such as unprotected high-altitude skydiving, high-speed racing, free climbing, etc., which may not only cause serious physical injury or even death, but also aggravate inner anxiety, fear and other negative emotions due to the huge risks in the process. Once the crisis is successfully overcome, a false sense of accomplishment may be generated, which will strengthen the tendency of dangerous behavior. 2. **Abuse of addictive substances**: including drugs (such as heroin, methamphetamine, etc.), excessive drinking, abuse of psychoactive drugs, etc., will disrupt the normal function of the brain, cause mental disorders, hallucinations, delusions, emotional loss of control, etc., and cause irreversible physical and psychological damage in the long run, further aggravating the sense of despair and forming a vicious cycle. 3. **Dangerous sexual behavior**: such as unsafe sexual behavior, casual sex with multiple people, etc., may lead to sexually transmitted diseases, unwanted pregnancy and other consequences, and will also trigger complex emotions such as shame, self-blame, anxiety, etc., which will have a great impact on the psychology. 4. **Violent aggressive behavior**: Violent destruction and attacks on others or objects may give people a so-called "sense of control" for a short period of time, but they will then face legal consequences and moral condemnation, greatly worsening their personal psychological state and leading to more serious self-loathing and social isolation.
