Underwear is in direct and prolonged contact with the skin, which is why its cleanliness and preservation are more important than is usually thought. Even though it is washed regularly, the material wears out over time, loses its protective function and becomes a suitable place for bacteria to grow. Therefore, the question of how often you should buy new underwear is not a matter of aesthetics, but of hygiene and health.
How long does underwear last?
There is no universal deadline, but in practice it is considered that underwear should be changed every six to twelve months, depending on the quality of the material, frequency of wearing and method of maintenance.
Underwear that is worn frequently, washed at high temperatures, and tumble dried tends to wear out faster. Cheaper synthetic materials have a shorter lifespan than quality cotton or blends with natural fibers.
Signs that it's time for replacement
Regardless of age, underwear should be replaced as soon as the following signs appear:
- thinned or damaged fabric
- lost elasticity
- persistent unpleasant odors even after washing
- discoloration that cannot be removed
- skin irritation after wearing
If underwear no longer fits properly or causes discomfort, its hygienic function has already been impaired.
How many pieces is optimal to have?
For everyday use, it is recommended to have at least 10 to 14 pieces of underwear, which allows for regular changes and washing without excessive wear and tear on the same items. Fewer pieces mean more frequent washing and faster deterioration of the material.
Material as an important factor
Cotton and other natural fabrics allow the skin to breathe and can withstand frequent washing more easily. Synthetic materials may be practical or aesthetically pleasing, but they wear out faster and are more likely to retain moisture, which can contribute to irritation.
How to extend the lifespan
The maintenance method significantly affects the durability of underwear:
wash it at recommended temperatures use mild detergents avoid aggressive fabric softeners air dry when possible
Even with proper care, underwear is not a permanent clothing category.
Regularly changing your underwear is part of basic personal hygiene. Although it is often overlooked, timely renewal of the clothing closest to the skin contributes not only to comfort, but also to maintaining health.
