Fabric choice matters too. Breathable materials like cotton allow moisture to escape, helping pajamas stay fresher longer. Synthetic fabrics, however, tend to trap heat and odors, which can shorten wear time and affect comfort during sleep.
In the end, there’s no strict rule—only what feels right for you. Paying attention to comfort, skin reactions, and overall freshness leads to smarter habits. With a little awareness, it’s easy to keep pajamas clean, lasting, and ready for restful nights ahead.
