Regaining smell and taste after COVID involves patience, smell training, proper nutrition, and sometimes medical intervention.
Why COVID Affects Smell and Taste
COVID-19 is notorious for causing a sudden loss of smell (anosmia) and taste (ageusia), which can last from days to months. The virus targets the olfactory system, specifically the support cells in the nasal cavity, disrupting the signals sent to the brain. Unlike typical colds that cause congestion blocking smells, COVID directly affects nerve cells responsible for sensing odors. This is why many people report losing taste as well since taste heavily depends on smell.
The loss of these senses can be distressing because they are closely tied to quality of life—flavors become muted or distorted, meals lose appeal, and even safety can be compromised (like detecting smoke or gas leaks). Understanding how COVID disrupts these senses helps guide recovery strategies.
The Science Behind Smell and Taste Recovery
The olfactory nerve has a remarkable ability to regenerate. After viral damage, basal cells in the nasal lining can produce new sensory neurons. However, this process takes time—often weeks or months. Taste buds also regenerate but at a faster rate than olfactory neurons.
Recovery depends on several factors:
- Severity of nerve damage: Mild damage often resolves quickly; severe damage takes longer.
- Age: Younger people tend to recover faster due to better regenerative capacity.
- Overall health: Good nutrition and absence of other illnesses support healing.
Some patients experience parosmia—distorted or unpleasant smells during recovery—which signals nerve regrowth but can be uncomfortable.
Smell Training: The Cornerstone of Recovery
Smell training is a proven technique that stimulates olfactory nerve regeneration by repetitively exposing the nose to specific scents. It’s simple but requires consistency.
How to do it:
- Select four distinct strong scents such as rose, lemon, eucalyptus, and clove.
- Twice daily, take slow deep sniffs of each scent for about 20 seconds.
- Focus on trying to remember what each scent smells like.
- Continue this routine for at least 12 weeks.
Studies show smell training improves recovery rates significantly compared to doing nothing. It helps retrain the brain’s olfactory pathways and speeds up nerve healing.
Tips for Effective Smell Training
- Use essential oils or natural items: Fresh lemons or cloves work well.
- Avoid irritants: Strong chemical smells can overwhelm sensitive nerves.
- Track progress: Keep a journal noting any changes in perception or intensity.
The Role of Hydration and Nasal Care in Recovery
Keeping nasal passages moist is vital since dryness can hamper nerve healing and worsen discomfort. Drinking plenty of fluids hydrates mucous membranes internally.
Nasal irrigation using saline sprays or rinses flushes out irritants and promotes healthy tissue environment. This practice soothes inflamed nasal linings damaged by the virus or post-viral inflammation.
However, avoid overusing decongestant sprays as they may cause rebound congestion and damage delicate tissues further.
Nasal Care Routine Suggestions:
- Mild saline spray: Use twice daily to keep nasal passages moist.
- Nasal irrigation with neti pot: Once daily if tolerated; use sterile water only.
- Avoid irritants: Smoke, strong perfumes, or pollution delay healing.
- Mild humidifiers: Adding moisture to room air prevents dryness especially during winter months.
- Avoid excessive nose blowing: Gentle blowing reduces trauma inside nostrils.
The Impact of Medical Treatments on Smell & Taste Recovery
In some cases where smell loss persists beyond several months with no improvement from smell training or home care alone, medical intervention may be necessary.
Doctors may recommend:
- Corticosteroids: Short courses reduce inflammation around olfactory nerves but should be used cautiously due to side effects.
- Nasal corticosteroid sprays: Target local inflammation with fewer systemic effects than oral steroids.
- Surgical options: Rarely needed unless structural issues like polyps block airflow to olfactory regions.
- Nutritional supplements: Zinc supplements might help but only under medical advice since excess intake can be harmful.
- Therapies under clinical trials: New treatments such as platelet-rich plasma injections are being explored but not widely available yet.
It’s important not to self-medicate without consulting an ENT specialist or neurologist experienced in post-COVID symptoms.
Lifestyle Changes That Promote Sensory Healing
Certain lifestyle habits influence how quickly your smell and taste return:
- Avoid smoking: Tobacco smoke damages olfactory receptors making recovery slower or incomplete.
- Avoid excessive alcohol consumption: Alcohol dehydrates tissues impairing healing processes.
- Mental exercises: Engaging your brain by identifying tastes and smells actively helps rewire sensory pathways during recovery.
- Mild physical exercise: Improves blood flow including circulation around nasal tissues supporting nutrient delivery for repair.
- Adequate sleep: Sleep cycles are crucial for nervous system restoration including sensory neurons affected by COVID-19 infection.
The Timeline: What to Expect While Recovering Smell & Taste After COVID
Recovery varies widely from person to person. Here’s a general timeline many experience:
- The first two weeks after infection: This is when most notice sudden loss of smell/taste; some regain partial function quickly within days while others remain anosmic longer.
- The first month: Sensory nerves start regenerating; some detect faint odors returning; parosmia may begin where smells seem distorted or unpleasant.
- The next three months: If you do smell training regularly during this phase recovery chances improve dramatically; many regain significant function.
- Beyond six months: If no improvement occurs by now consult specialists; persistent anosmia may require advanced therapies.
Patience is key because nerves recover slowly. Don’t get discouraged if progress feels minimal at times—it often happens gradually with small wins adding up over weeks.
The Importance of Mental Health During Recovery
Loss of smell/taste impacts emotions deeply—food enjoyment fades away causing frustration or even depression in some cases. Social interactions involving meals become less appealing too.
Being aware that this condition is temporary for most helps maintain hope. Joining support groups online where others share their experiences provides encouragement.
Mindfulness techniques focusing on present sensations help reduce anxiety related to distorted smells (parosmia). Staying positive encourages better adherence to recovery routines like smell training.

Frequently Asked Questions
How to get smell and taste back after COVID with smell training?
Smell training is a key method to regain smell and taste after COVID. It involves sniffing four distinct scents like rose, lemon, eucalyptus, and clove twice daily for about 20 seconds each. This repetitive exposure helps stimulate nerve regeneration and retrains the brain’s olfactory pathways.
Why does COVID cause loss of smell and taste?
COVID affects smell and taste by targeting support cells in the nasal cavity, disrupting signals sent to the brain. Unlike typical colds, it damages olfactory nerves directly, which leads to anosmia and ageusia. Since taste depends heavily on smell, both senses are often lost together.
How long does it take to get smell and taste back after COVID?
The recovery time varies depending on nerve damage severity, age, and health. Mild cases may regain senses within days or weeks, while severe damage can take months. The olfactory nerve regenerates slowly, so patience and consistent recovery practices are essential.
Can nutrition help in getting smell and taste back after COVID?
Proper nutrition supports overall healing and nerve regeneration critical for recovering smell and taste after COVID. A balanced diet rich in vitamins, minerals, and antioxidants helps repair damaged tissues and boosts immune function during recovery.
When should I seek medical help to get smell and taste back after COVID?
If loss of smell and taste persists beyond several months or worsens with distorted smells (parosmia), consulting a healthcare professional is advised. Medical interventions or therapies may be necessary to aid nerve healing and address underlying issues.
Conclusion – How to Get Smell and Taste Back After COVID
Recovering your sense of smell and taste after COVID involves more than just waiting it out—it requires active steps like consistent smell training combined with good nutrition, proper nasal care, healthy lifestyle choices, and sometimes medical help.
