What can’t be shared?

Normally when people are at home, many things are shared. When living in dormitories, people also share many things. However, we need to remind everyone that many daily necessities cannot be shared. For example, everyone knows that everyone can only use their own toothbrush. In addition to toothbrushes, the following items are also best not to be shared.

What can’t be shared?

1. Soap

If you think soap is used to sterilize and disinfect and can be used casually, you are wrong. The bottom of soap is usually wet, which can become a breeding ground for bacteria. Studies have found that the bacteria on soap can be cross-transmitted between different users.

2. Hat and Comb

Hats and combs come into direct contact with the head and sharing them may spread fungi. In addition, the head may be contaminated with mites due to contact with pillows, sheets, sofas, etc., and cross-infection is likely to occur if a hat comb is shared.

3. Nail Clippers

When trimming nails, if the skin is accidentally broken, sharing nail clippers may cause infection with blood-borne bacteria, such as hepatitis C virus, Staphylococcus aureus, etc. It is recommended to disinfect manicure tools with alcohol after use.

4. Bottled drinks

Drinking from the same bottle of beverage can easily lead to infection of pharyngitis, influenza, mumps and even meningitis through saliva contact. So it’s better to drink your own drinks, or pour them into cups and share.

5. Headphones

Headphones can easily be contaminated with bacteria if used for a long time, and sharing them will allow bacteria to be transmitted from ear to ear. This is especially true for head-mounted headphones provided in public places such as school computer rooms, which should be disinfected regularly.

6. Cosmetics

Most cosmetics such as lipstick and mascara contain preservatives, which have antibacterial properties and are safer to share. However, if the user suffers from infectious diseases such as conjunctivitis, influenza, etc., they cannot share the same product.

7. Razor

Razors can easily cut the skin and get stained with blood. Sharing them can easily spread hepatitis B virus, etc. Any items that easily bleed should not be shared, and must be disinfected after use.

8. Toothbrush

Sharing a toothbrush can cause bacteria on the bristles to be transmitted through the oral cavity, especially when the user's gums or mouth are injured, the bristles are easily stained with blood, increasing the risk of infection.

9. Earrings

Best friends often exchange earrings and other accessories. If they are worn when the ear holes are dry, it is generally fine. However, when taking them off, they may scratch the ear holes and get them stained with blood. If they are then lent to others, various viruses can easily be spread through the blood. Therefore, the earrings should be cleaned and disinfected after being removed.

10. Antiperspirant

Roll-on antiperspirants themselves have no bactericidal effect. Sharing them may transmit bacteria and fungi in sweat to others. If you want to share them, please use spray antiperspirants instead.
