How To Regain Smell And Taste When Sick-try This First
To regain your sense of smell and taste when sick, start olfactory training immediately using four strong scents like lemon, clove, rose, and eucalyptus-sniff each for 20-25 seconds twice daily while vividly imagining the aroma, as recommended by neurologists for post-viral recovery with up to 70% improvement rates within three months.
Understanding the Loss
Sensory loss during illness, especially from viruses like COVID-19, affects over 60% of patients, damaging olfactory nerves and causing anosmia (no smell) or ageusia (no taste), per a 2025 Henry Ford Health study. This happens when inflammation blocks nasal receptors or viruses directly invade nerve cells, lingering weeks to months post-recovery. Standalone, this disruption explains why everyday foods lose flavor, impacting nutrition and mental health.
Proven First Steps
The fastest initial action is clearing nasal passages with saline rinses, which reduce inflammation and promote drainage, restoring partial senses in 40-50% of cases within days, according to ENT specialists. Use a neti pot or NeilMed Sinus Rinse daily, followed by steroid sprays like Flonase if prescribed. Dr. Danoun warns against unsafe trends like inserting garlic, emphasizing evidence-based methods only.
- Prepare saline solution: 1 tsp non-iodized salt in 2 cups warm distilled water.
- Irrigate gently to avoid irritation, twice daily for best results.
- Combine with steam inhalation using eucalyptus oil for added nerve stimulation.
Olfactory Training Protocol
Olfactory training, pioneered in 2009 by Prof. Thomas Hummel, retrains brain-nose connections by repeated exposure to odors, showing 52% full recovery in long-term COVID cases per 2025 trials. Begin within six weeks of loss for optimal 80% success odds, as UCHealth's Dr. Jennifer Reavis Decker advises. Track progress in a journal, noting faint detections as early wins.
- Select four scents: citrus (lemon), floral (rose), fruity (clove), resinous (eucalyptus).
- Sniff each 20-25 seconds, twice daily (morning/night), for three months minimum.
- Mentally visualize and recall memories tied to the scent during whiffs.
- Rest one minute between scents; switch oils after three months if needed.
- Consult a doctor if no improvement after six weeks.
Supporting Nutrition and Hydration
While senses recover, boost intake of zinc-rich foods like oysters and nuts (15-30mg daily), as deficiency worsens anosmia in 25% of cases, Harvard Health reports from 2023 data. Omega-3s from fish oil aid nerve repair, with studies showing 30% faster recovery when combined with training. Stay hydrated to thin mucus, enhancing scent delivery to receptors.
| Nutrient | Benefit | Source | Dose |
|---|---|---|---|
| Zinc | Nerve regeneration | Oysters, beef | 15-30mg |
| Omega-3 | Reduces inflammation | Salmon, supplements | 1-2g |
| Vitamin A | Epithelial repair | Carrots, liver | 700-900mcg |
| Vitamin C | Antioxidant support | Citrus, peppers | 75-90mg |
Medical Interventions
For persistent cases beyond three months, topical corticosteroids like budesonide rinses cut inflammation, restoring smell in 65% of post-viral patients per 2023 Fagron Academy review. Intranasal vitamin A sprays show promise in European trials since 2022, regenerating epithelium. Avoid smoking, which delays recovery by 50%, and get vaccinated to prevent recurrence, as 2026 UCHealth data confirms.
"Your best shot at improving your sense of smell is during the first 6 weeks after losing it." - Dr. Jennifer Reavis Decker, UCHealth ENT, April 2026.
Lifestyle Adjustments
Enhance training with textured, spicy foods like ginger shots-blend 10g fresh ginger, lemon zest, honey, and vinegar for trigeminal stimulation, aiding 40% of ageusia cases. Chew thoroughly to engage taste buds mechanically. A 2025 BioDesign Wellness case saw full recovery after 30 days of anti-inflammatory peptides like BPC-157, though consult professionals first.
Timeline and Expectations
Expect gradual return: 30% recover in weeks, 50% by three months, 20% need longer intervention, based on 2025 ION Academy longitudinal study of COVID survivors. Parosmia (distorted smells) may precede normalcy-persist with training. See an ENT if no progress by six weeks to rule out polyps or neurological issues.
Advanced Therapies
Emerging platelet-rich plasma (PRP) injections, trialed in 2024 U.S. clinics, regenerate nerves in 60% of chronic cases. High-molecular hyaluronic acid sprays with mint oil reduce inflammation, as 2023 studies indicate. Track via apps like AbScent, founded post-2020 pandemic, aiding 100,000+ users.
- PRP: Weekly injections for 4-6 weeks under ENT guidance.
- Hyaluronic sprays: Twice daily, anti-inflammatory base.
- Mint oil: Stimulates trigeminal nerves for hybrid sensation.
Prevention Strategies
Avoid nasal trauma and allergens; annual flu shots cut viral anosmia risk by 35%, CDC 2025 stats show. Maintain nasal hygiene year-round. Post-illness, start training proactively-even mild cases benefit.
| Training Start | Full Recovery Rate | Partial Recovery |
|---|---|---|
| <2 weeks | 80% | 95% |
| 2-6 weeks | 65% | 85% |
| >6 weeks | 40% | 70% |
Historical Context
Post-viral anosmia surged in 2020 with COVID, affecting 10 million globally by 2021, prompting Hummel's protocol evolution from 2009 rhinitis trials. By May 2026, 85% of long-haulers recover via combined methods, per Harvard updates. This empowers proactive management amid ongoing variants.

Helpful tips and tricks for How To Regain Smell And Taste When Sick
How long does recovery take?
Most regain senses within 2-12 weeks with training; 70-80% full recovery by six months if started early.
Is olfactory training safe?
Yes, it's non-invasive and endorsed by global ENT bodies since 2017, with no side effects beyond mild fatigue.
What if I have parosmia?
Continue training with milder scents; it resolves in 90% of cases within months as nerves rewire.
Can supplements alone fix it?
No, they support but training is primary; zinc alone aids only 20-30% without protocol.
Does COVID vaccination help?
Yes, vaccinated individuals lose senses 50% less often and recover faster, per 2026 data.
Why does taste rely on smell?
80% of taste is olfactory; retronasal airflow carries aromas during chewing to nasal receptors.
Can stress delay recovery?
Yes, cortisol hinders neuroplasticity; mindfulness boosts outcomes by 25%.
Is surgery ever needed?
Rarely, for polyps obstructing 10% of chronic cases; endoscopy diagnoses.
