Did you know that sunglasses or running shoes also have a lifespan, even when manufacturers don't recommend it?
Did you know that we should change our hairbrush every year? Many products and tools deteriorate over time and expire, but we often can't perceive it with the naked eye, so we continue to use them. Manufacturers don't specify the expiration date of these items, but they still have a recommended period of use that you should consider:
1. Running Shoes

These shoes tend to wear out with use. Over time, the cushioning foam of the shoes deforms and flakes off, causing the outer sole to wear out. Additionally, the shoes may crack and peel. Although it depends heavily on the weather, the type of terrain you walk on, and the amount of sweat, always replace your shoes when you feel uncomfortable while running, even causing pain or injury.
Some manufacturers advise replacing shoes after running 400 to 500 miles, while others suggest signs of deterioration may begin after 6 months to 1 year of use. However, your own feeling is still the most important and accurate.
2. Headphones

The lifespan of headphones will depend on their quality. Generally, if the headphones are of good quality, they can last from 4 to 5 years. These products are affected by normal wear and tear, sweat, how they are stored, and whether you frequently pull or tie the cords.
3. Eyelash Glue

False eyelash glue is another product that people often use for longer than recommended. Remember that we apply glue very close to our eyes, so don't be complacent. When unopened, they can last from 3 to 4 months. However, once opened, you should use them within 4 to 5 weeks.
4. Makeup Brushes

Remember, just like makeup, the longevity of tools depends on the inherent quality of the product. For brushes that directly touch the skin, if they are of very good quality and cleaned properly, they can last from 10 to 12 years. But if they are cheaper ones, we should discard them when the brushes start shedding 'small hairs'.
5. Sunglasses

Sunglasses not only make us look better but also protect our eyes from the sun's rays. But never forget that sunglasses can also expire. On average, you should replace sunglasses after wearing them for 2 hours every day for 2 years because by then the lenses have lost their protective properties.
6. Hairbrush

This paddle brush is where bacteria, dandruff, dust, and other dirt accumulate and they will pass through the scalp every time we brush our hair. Therefore, an old brush can cause irritation and clog hair follicles. We should thoroughly clean the brush every month and pay attention to its appearance to know when it's time to replace it.
If the brush bristles are damaged, the brush can no longer clean effectively, or the cushion is too soft or has cracks, then it's time to buy a new one. Cosmetic expert Essie Tiffany Button advises changing this product every 6 to 12 months, especially if it's made of plastic or rubber.
7. Indoor Slippers

Unlike other types of footwear, indoor slippers are often used daily so they may deteriorate faster. Generally, their average lifespan is 1 year, but this also depends on how much we use them and the quality of the product.
8. Bath Towel

We often replace bath towels mainly because they tear or fray. But if the towels are of good quality and never deteriorate, people tend to keep using them year after year. You should check if they still have the ability to absorb water because this may gradually diminish after about 2 years no matter how good or durable the towel is.
9. Pillow

Without regularly replacing pillows, we may experience allergies, neck pain, or even acne. Specialists advise not only cleaning these products but also replacing them after 1 or 2 years of use.
10. Kitchen Sponge

This sponge removes all residue from our dishes, so it needs to be replaced regularly. Additionally, you should also wash the sponge with hot water daily to prolong its lifespan, as well as replace it weekly or when you notice any odor or slime.
