Hello! We do apologize for the delay. Please note that we are currently experiencing a very heavy backlog of asks, dating back to mid-December. While we’re doing our best to fill the queue with asks, if you sent one later than December 15, it may take some time for us to unearth. For all emergencies, please consider using your local pokémon center. —LH
When vocal strain occurs, either for humans or for pokémon, it’s important to rest. You see, the voice is produced by the vocal cords, which are less cords and more bands of muscle surrounding the larynx, or voice box (which itself is situated just above the wind pipe in all organisms that possess lungs and are capable of sound production). As with all muscles, overuse of the vocal cords can strain them, especially if the speaker hasn’t exactly been exercising proper self-care. However, just like any other muscle, it’s not that difficult to recover from a strained voice; it’s just a matter of practicing vigorous self-care in the meantime.
For one, yes, rest is important. If at all possible, have your primarina avoid using her voice to attack. Switch to more basic, non-water moves such as Moonblast and take this as an opportunity to practice her other techniques. If your primarina has a habit of shouting while battling, try your best to train her not to do this to avoid straining her voice further. This may also be a great opportunity to add stealth training to your regimen.
Off the battlefield, be sure she’s well-hydrated. While this seems obvious for a water-type, what I mean is she should be more hydrated than she is currently. Have her drink plenty of water, and allow her plenty of time to rest in humid environments. Consider purchasing a humidifier as well; it’s extremely important to ensure that the air around your primarina isn’t dry, as this will dry out the vocal cords and lead to further problems.
Also, be sure that your primarina gets an adequate diet that doesn’t irritate her throat or dry out the mucous membranes around her vocal folds. Not a lot of trainers think about this when their pokémon are ill, but diet can be extremely vital to one’s recovery. In your primarina’s case, avoid dry or spicy berries and beans (even if she likes them), and supplement her diet with vitamins A, C, and E. The latter can be found naturally in sour or bitter berries, as well as grains. Most brands of commercial poké kibble for the popplio line include grains or are fortified with the aforementioned vitamins for this express reason (that is, because the line is so reliant on vocal health), but be sure to check the label before purchasing.
Finally, while it’s important for your primarina to exercise, be absolutely sure she gets plenty of actual rest as well. Have her sleep for a minimum of eight hours a day, and don’t let her overexert herself otherwise.
It may take a week or two of rest and proper care before your primarina gets back on her metaphorical feet, but if her condition lasts longer, take her to your nearest pokémon center. If, however, she recovers within a week, your regimen of self-care shouldn’t stop here. Be sure to keep her hydrated, and train her to use proper singing techniques for Sparkling Aria. Have her maintain the proper posture (back straight, shoulders back) and be sure she supports her voice with deep breaths from the chest. Never sing using the vocal cords or throat alone, and certainly don’t do it while slouching. Additionally, give her plenty of time to rest between battles as well; never have her run a gauntlet of battles or “spam” Sparkling Aria.
Best of luck!
