Tension loss is the only physically significant process impacting your tennis racket (and string wear). This is why rackets need to be restrung. To fully appreciate the benefits of fresh strings, you need to consider what tension loss does to racket performance.

Should I restring my tennis racquet?

As a general rule you should re-string each year as often as you play per week. If you play twice per week, you should restring your racket twice per year. All strings gradually stretch and lose their resiliency or go dead, even if you play infrequently.

Why do tennis rackets need to be restrung?

Your strings begin losing tension the moment your racket is taken off the stringing machine. Re-stringing every three months will keep your string tension as consistent as possible, resulting in a much better learning experience.
