Olfactory recovery after COVID often involves smell training, patience, and sometimes medical interventions to restore scent perception.
The Impact of COVID-19 on the Sense of Smell
The loss of smell, or anosmia, emerged as one of the hallmark symptoms during the COVID-19 pandemic. Unlike typical colds or flu, where congestion blocks nasal airflow causing temporary smell loss, COVID-19 often causes a sudden and profound olfactory dysfunction even without nasal obstruction. This unique symptom puzzled scientists early on and has since been a focus for researchers and clinicians alike.
SARS-CoV-2, the virus responsible for COVID-19, affects the olfactory system by targeting supporting cells in the nasal epithelium rather than directly attacking olfactory neurons. This indirect damage disrupts the function of sensory neurons responsible for detecting odors. The good news is that in many cases, this damage is reversible, but recovery times vary widely—from days to months.
Understanding how to regain your sense of smell after COVID requires knowledge of the olfactory system’s anatomy and how it interacts with viral infection.
How Does Smell Loss Occur With COVID?
Olfaction starts when odor molecules bind to receptors on sensory neurons located in the olfactory epithelium inside the nose. These neurons send signals through the olfactory nerve directly to the brain’s olfactory bulb, which processes smells.
COVID-19 disrupts this process primarily by affecting non-neuronal cells called sustentacular cells. These cells provide metabolic and structural support to olfactory neurons. When infected, sustentacular cells become damaged or die off, leading to a breakdown in the environment necessary for neuron survival and function.
Additionally, inflammation triggered by the immune response can exacerbate damage. In some cases, this inflammation spreads to the olfactory bulb itself or other brain regions linked to smell perception.
The extent of damage can range from mild dysfunction to complete anosmia. Some patients also report parosmia (distorted smells) or phantosmia (phantom smells) during recovery phases.
How Can I Get My Smell Back After COVID? Effective Strategies
Recovering your sense of smell after COVID isn’t always straightforward, but several evidence-based methods can help speed up or improve outcomes.
1. Smell Training: The Cornerstone of Recovery
Smell training involves deliberately sniffing a set of distinct odors twice daily over several weeks or months. This practice stimulates olfactory neurons and promotes neural regeneration and plasticity.
Commonly used scents include:
- Rose
- Lemon
- Eucalyptus
- Clove
The idea is that repeated exposure “exercises” your sense of smell and helps retrain your brain’s ability to recognize odors. Clinical studies have shown significant improvement in patients who stick with smell training compared to those who do not.
2. Patience and Consistency Are Key
Nerve cells regenerate slowly—olfactory receptor neurons take roughly 30 days to renew under normal conditions. After viral injury, this process can take longer.
It’s crucial not to get discouraged by slow progress or temporary setbacks like distorted smells (parosmia). Consistent practice over weeks or months often yields gradual improvement.
3. Avoid Nasal Irritants and Maintain Nasal Health
Irritants such as smoke, strong chemicals, and pollution can further inflame nasal tissues impairing recovery. Using saline nasal sprays can keep mucosa moist and clear debris gently without harsh chemicals.
Maintaining good nasal hygiene promotes an optimal environment for nerve healing.
The Science Behind Smell Training Explained
Smell training leverages neuroplasticity—the brain’s ability to reorganize itself by forming new neural connections throughout life. When you repeatedly expose yourself to specific odors, you activate pathways between sensory neurons and higher brain centers involved in odor identification.
Research shows that patients performing smell training demonstrate:
- Increased volume in their olfactory bulbs seen via MRI scans.
- Improved scores on standardized smell identification tests.
- A reduction in parosmia symptoms over time.
This approach is low-risk, inexpensive, and easy to implement at home with essential oils or scented objects.
The Role of Mental Health During Smell Recovery
Losing your sense of smell can be distressing—smells connect deeply with memories and emotions as well as safety cues like detecting smoke or spoiled food. The sudden absence or distortion impacts quality of life significantly.
Frustration from slow progress sometimes leads people into anxiety or depression cycles that indirectly affect motivation for treatment adherence.
Mindfulness practices such as meditation or gentle exercise may help manage stress while supporting neurological health indirectly through improved circulation and reduced inflammation.
The Timeline: What To Expect When Regaining Your Sense of Smell Post-COVID?
Recovery timelines differ widely based on severity of initial damage and individual factors like age or pre-existing conditions.
- Within Days to Weeks: Some regain partial smell spontaneously as inflammation subsides.
- 1–3 Months: Many experience gradual improvement with consistent smell training.
- Beyond 6 Months: Persistent anosmia may require medical evaluation; some patients develop parosmia during this phase indicating nerve regrowth but miswiring.
- A Year or More: Rare cases experience prolonged anosmia; ongoing research explores advanced therapies like stem cell treatments for these patients.
Tracking progress using simple at-home tests (like identifying household scents) can provide motivation through visible improvements over time.
Cautions: What Not To Do During Your Smell Recovery Journey?
Avoid self-medicating with unproven supplements claiming miracle cures—they risk side effects without scientific backing. Also steer clear from excessive use of nasal decongestants as they may dry out mucosa hindering nerve regeneration.
Do not ignore persistent symptoms if they worsen or are accompanied by other neurological signs such as headaches or vision changes—seek immediate medical attention if these occur.

Smell training is a proven method to help regain your sense of smell after COVID. It involves regularly sniffing specific scents twice daily to stimulate olfactory nerves and promote recovery. Consistency over weeks or months is key for effective results.
How Can I Get My Smell Back After COVID If It Does Not Improve Quickly?
If your smell does not return quickly, patience is important as recovery times vary widely. Consult a healthcare professional who may recommend medical interventions or therapies to address persistent olfactory dysfunction caused by COVID-19.
How Can I Get My Smell Back After COVID When Experiencing Distorted Smells?
Distorted smells, or parosmia, are common during recovery after COVID. Continuing smell training and avoiding strong irritants can help. Over time, the brain relearns normal scent perception as inflammation decreases and olfactory neurons heal.
How Can I Get My Smell Back After COVID If Inflammation Is Affecting Recovery?
Inflammation can worsen smell loss after COVID. Managing inflammation through medical advice and possibly anti-inflammatory treatments may support olfactory nerve healing. Reducing nasal irritation and following prescribed therapies can aid in restoring your sense of smell.
How Can I Get My Smell Back After COVID Without Nasal Congestion?
Unlike typical colds, COVID-related smell loss often occurs without congestion due to damage to supporting cells in the nose. Recovery focuses on repairing these cells and neurons through smell training and time, rather than treating nasal blockage.
The Role of Emerging Treatments in Olfactory Dysfunction Post-COVID
Researchers continue exploring new options beyond traditional methods:
- Nasal Platelet-Rich Plasma (PRP): Early studies suggest injecting PRP into nasal tissues might accelerate healing by delivering growth factors directly where needed.
- Liposomal Vitamin A: Enhanced delivery systems aim to improve absorption into nasal mucosa compared with standard drops.
- Cognitive Olfactory Training: Combining scent exposure with memory exercises targets both peripheral nerves and central processing centers simultaneously for better outcomes.
While promising results exist from small trials, these remain experimental pending larger randomized controlled studies before becoming routine care options.
Conclusion – How Can I Get My Smell Back After COVID?
Recovering your sense of smell after COVID requires a multifaceted approach centered around patience and active rehabilitation techniques like consistent smell training combined with supportive care including good nutrition and avoidance of irritants.
