You should change your bed sheets at least once every two weeks, according to general recommendations. However, most experts and studies suggest washing them once a week for optimal hygiene and freshness

. More frequent washing is advised if you:

• Suffer from night sweats or allergies such as asthma (weekly washing helps remove grime and irritants)

• Sleep with pets, as pet hair, dander, and dirt accumulate quickly (changing sheets every 3-4 days or twice a week is recommended)

• Experience warmer weather or sweat more during summer months (weekly laundering keeps sheets fresh)

While the average person tends to change sheets every two to three weeks, this is less ideal and can lead to buildup of sweat, dead skin cells, oils, dust mites, bacteria, and allergens, which may cause skin irritation, allergies, or discomfort affecting sleep quality

. In summary:

• Ideal frequency: Once a week
• Minimum frequency: Every two weeks
• More frequent: Weekly or more if you sweat a lot, have allergies, pets, or hot weather conditions

Regularly changing sheets supports better hygiene, skin health, and sleep quality
