If you frequently sanitise, then these consequences are for you.
Besides killing the good bacteria in the palms, it creates a place for the bad bacteria or the harmful bacteria to grow rapidly at a faster rate. When sanitizers are used very often these bad bacteria get used to it and will develop resistance against it. Later using sanitizer has no point as it cannot kill the bad bacteria anymore. Some people keep sanitizing their hands immediately every time they sneeze or cough. Sanitizers cannot kill the germs or bacteria, viruses in the air. Therefore it is recommended to reduce the usage of sanitizers. Instead, soap water helps better in cleaning hands and killing germ without any harm to us. The US Centers for Disease Control and Prevention claims germs can be prevented by washing hand cleanly with soap.
There were few cases during the lockdown where few people drank sanitizers when alcohol was no longer available to drink. Physicians warn that drinking sanitizer can lead to lung damage, lipid pneumonia, and illness. health experts warn that drinking sanitizer may lead to vomiting diarrhea, kidney damage and shortly it may lead to death. This is how dangerous sanitizer is.
