Most people recover from COVID-19 within one to two weeks, but several evidence-based strategies can shave days off that timeline. The biggest levers are starting antiviral treatment early (if you qualify), keeping your nasal passages clear with saline rinses, prioritizing sleep, and managing symptoms with the right over-the-counter medications. Here’s what actually works and by how much.
Saline Nasal Rinses: A Surprisingly Effective Tool
One of the simplest and most accessible ways to shorten COVID is also one of the least discussed. Rinsing your nasal passages with saline solution, using a neti pot, squeeze bottle, or similar device, can reduce the duration of viral shedding by roughly 5 days compared to doing nothing, according to research published in Frontiers in Public Health. The key is starting early in the infection, before other treatments have been introduced.
The benefit is especially pronounced if you have significant nasal congestion or a runny nose at the start of your illness. In patients with those symptoms, recovery of the ability to do daily activities came 4.5 days sooner, postnasal drip resolved about 4 days faster, and sore throat cleared more than 3 days earlier. Aim for at least two rinses per day, and up to every four hours if your symptoms are moderate or you’re dealing with chest congestion. Isotonic saline (the same salt concentration as your body) works well, and premixed packets are available at most pharmacies.
Prescription Antivirals: Who They Help
Paxlovid remains the most commonly prescribed antiviral for outpatient COVID, but its benefit depends heavily on your risk profile. In the original clinical trials, it significantly reduced hospitalizations and deaths among unvaccinated, high-risk adults. However, a later study among fully vaccinated people found it did not meaningfully shorten symptoms: median time to symptom relief was 12 days with Paxlovid versus 13 days with placebo.
This doesn’t mean antivirals are useless. They still reduce the risk of severe illness, which is their primary purpose. The CDC recommends clinicians consider antiviral treatment for anyone with mild or moderate COVID who has risk factors for progression. Those risk factors include being over 65 (with risk rising sharply after 75), having multiple chronic health conditions, being immunocompromised, or not being up to date on vaccinations. If you fall into one of those categories and test positive, contacting a provider within the first day or two matters. Antivirals work best when started within five days of symptom onset, and ideally sooner.
For otherwise healthy, vaccinated adults, the evidence suggests antivirals won’t noticeably speed up your recovery. The strategies in this article that address symptoms and support your immune response are likely to make a bigger practical difference for you.
Metformin: An Unexpected Option
Metformin, a widely available diabetes medication, showed notable results in the COVID-OUT clinical trial. Participants who took it during acute COVID had a 3.6-fold reduction in viral load compared to placebo. More practically, they experienced a 42% reduction in emergency room visits, hospitalizations, and death within 14 days, and a 58% reduction in hospitalizations and death within 28 days. Perhaps most striking, metformin was associated with a 42% reduction in long COVID through 10 months of follow-up.
This is still an off-label use, and not every provider will prescribe it for COVID. But if you’re at higher risk for severe illness or concerned about long COVID, it’s worth asking about. The medication is inexpensive, generic, and has a long safety track record.
Choose Acetaminophen Over Ibuprofen
When reaching for something to manage fever, body aches, and headaches during COVID, acetaminophen (Tylenol) is the better choice. Early in the pandemic, researchers and senior doctors raised concerns that ibuprofen and other NSAIDs could slow recovery. The reasoning: ibuprofen’s anti-inflammatory properties may dampen the immune response at a time when your body needs it most.
There’s also broader evidence that NSAIDs are associated with prolonged illness and a higher rate of complications from respiratory infections, including both respiratory and cardiovascular issues. While occasional ibuprofen use is unlikely to be dangerous, acetaminophen lets you manage pain and fever without interfering with your body’s ability to fight the virus. Stick with it as your default throughout your illness.
Sleep Is Not Optional
Sleep is one of the most powerful tools your immune system has, and the data backs this up for COVID specifically. A cohort study tracking COVID patients found that those with insomnia had significantly longer durations of viral shedding. Patients sleeping poorly were measurably less likely to clear the virus within seven days of diagnosis compared to those who slept well, even after adjusting for other factors like anxiety and depression.
This means the advice to “rest up” isn’t just a pleasantry. Protecting your sleep during COVID is an active recovery strategy. If you’re struggling to sleep because of congestion, coughing, or discomfort, treating those symptoms (with acetaminophen, nasal rinses, or an elevated pillow position) does double duty by also improving the sleep that helps you recover faster. Aim for at least seven to eight hours, and don’t feel guilty about napping during the day. Your body is doing real work while you’re asleep.
Hydration and Practical Recovery Tips
Fever, sweating, and reduced appetite during COVID can quietly push you toward dehydration, which worsens fatigue, headaches, and brain fog. Drinking enough fluid won’t directly kill the virus, but it keeps your mucous membranes moist (helping them trap and clear pathogens), supports your kidneys as they process inflammatory waste products, and prevents the secondary symptoms that make you feel worse than the infection alone warrants. Water, broth, and electrolyte drinks all work. If your urine is pale yellow, you’re on track.
Beyond hydration, a few practical choices help your body focus its energy on recovery. Eat when you can, even if your appetite is poor; protein-rich foods give your immune system the raw materials it needs. Avoid alcohol entirely, as it disrupts sleep quality and suppresses immune function. And resist the urge to “push through” with exercise or work. Physical exertion during acute infection diverts resources away from your immune response and can extend your illness. Light movement like walking to the kitchen is fine, but save the workouts for after your symptoms resolve.
Timing Matters More Than Any Single Intervention
The common thread across nearly every strategy that shortens COVID is that they work best when started early. Nasal rinses lose much of their advantage if you wait several days. Antivirals must be started within five days. Sleep debt accumulated in the first few days of infection translates directly into longer viral shedding. The moment you test positive or strongly suspect COVID, that’s when to begin: start rinsing, take acetaminophen for symptoms, prioritize sleep, hydrate aggressively, and contact a provider about antivirals or metformin if you have risk factors. Stacking these interventions together, rather than relying on any single one, gives you the best chance of getting back to normal sooner.
