There are many pros and cons of electrical blankets. Firstly, electric blankets are convenient and they don't cost much. They only cost forty dollars which is pretty cheap for an electric blanket. However, they are hazardous. They give off an electromagnetic field, which is both an electric and a magnetic field. Electromagnetic fields can affect your genes, DNA(deoxyribonucleic acid), and your cells. Electrical blankets can also affect the environment negatively, because they can cause fires if they are not used properly.
