1. Wash your hands every time you come indoors.
If you use public transport, chances are that you have come into contact with surfaces that were touched by several other people. Make sure that you wash your hands with soap.
2. Wash your socks.
This is important not only for your personal health but it is also in general public interest. As you move around, your socks accumulate a lot of dust and bacteria.
3. Don't rub your eyes.
Rubbing your eyes with contaminated hands can transfer a lot of germs into them and cause eye infections.
4. Use a hand sanitiser.
For times when you can't wash your hands, carry a hand sanitising lotion with you. This becomes particularly important when you have to eat out in the middle of the day.
5. Carry tissues when commuting.
Tissues are better than cloth handkerchiefs as the latter accumulate germs on them, leading to infections. Therefore, carrying wet tissues is a better idea as they are disposable.
6. Avoid touching your hair.
The hair is one of the most exposed areas of the body. Avoid touching your hair to prevent transferring those germs on to your hands.
7. Use a deodorant.
Most people travelling by public transport stink, but that's no reason for you to join the club. A deodorant will also allow you to reduce the chance of bacteria breeding on your skin.
8. Treat skin infections in time.
Skin infections, if ignored, tend to aggravate and spread all over the body.
9. Clean your hands after playing with pets.
While playing with pets and strays is nice, they carry germs. Make sure to wash your hands before you sit down to eat your meal.
10. Get immunised.
In big cites with lots of people, you don't know what surface carries what infection. Get yourself immunised against some common infections such as tetanus.
