Germs are tiny living things that can make you sick, especially after touching public surfaces like doorknobs or bus rails. You should wash your hands for at least 20 seconds—enough time to sing the "Happy Birthday" song twice. The best way to remove germs is to use both soap and water. If soap is not available, you can use a hand sanitizer with at least 60% alcohol.

Question : How many seconds should you wash your hands for?

40

Poor posture, like slouching at a desk or looking down at a phone, puts huge pressure on your spine. This can lead to back pain and neck stiffness over time. When sitting, your feet should be flat on the floor and your chair should support your lower back (lumbar region). Keeping your computer screen at eye level is key to preventing headaches and strain.

Question : To prevent headaches, where should your computer screen be placed?

eye level

head level

lumbar level

Experts recommend turning off all screens at least 60 minutes before you plan to go to sleep. A good night's rest needs a dark, screen-free room.

Question : How many minutes before sleep should you turn off all screens?
