Every year between about November and February, the dry, dusty harmattan wind sweeps down from the Sahara across Nigeria. The air turns cool in the morning, hazy by afternoon, and very dry all day. For many people it is a pleasant break from the heat. But for others, harmattan brings a familiar set of complaints: tight chests, endless catarrh, cracked lips, ashy skin, and red, itchy eyes. Understanding harmattan health in Nigeria — why the season affects your body and what you can do about it — helps you get through these months in comfort. This article is for general information and is not a diagnosis.
Why harmattan affects your body
The harmattan wind carries fine dust and very little moisture. That combination is the root of most seasonal trouble. The dust irritates your airways, nose, and eyes, while the dryness pulls water out of your skin, lips, and the protective linings of your nose and eyes. People in northern states like Kano, Kaduna, Sokoto and Maiduguri often feel it strongest, but the haze and dryness reach Abuja, Lagos, Ibadan and the whole country during a heavy harmattan. If you already live with asthma or allergies, these conditions can flare more easily.
Harmattan and asthma
Cold, dry, dusty air is a classic asthma trigger. During harmattan, many people with asthma notice more coughing, wheezing, chest tightness, and shortness of breath, especially early in the morning or after being outside in the haze. The dust acts as an irritant, and the cool dry air can tighten the airways. The most important thing is to keep your asthma well controlled before symptoms get bad. If your doctor has prescribed a preventer (controller) inhaler, use it every day as directed, even when you feel fine, and always keep your reliever (rescue) inhaler with you. You can read more on our asthma page, and if you are unsure whether your inhalers are working well this season, a doctor on GoDoctor can review your symptoms and your inhaler technique by video or chat.
When breathing trouble is an emergency
Severe asthma can be life-threatening. Call 112 or 199, or go straight to the nearest hospital, if you or someone else has: lips or fingertips turning blue or grey, struggling so much to breathe that talking in full sentences is impossible, a reliever inhaler that is not helping after repeated puffs, or a child who is drowsy, very pale, or gasping. Do not wait it out at home.
Harmattan catarrh and the runny nose
Catarrh — that blocked or runny nose, sneezing, and post-nasal drip — is one of the most common harmattan complaints. Some of it is simple irritation from dust and dry air drying out the nose. Some of it is allergic rhinitis, where dust acts like an allergen and sets off sneezing, an itchy nose, and watery eyes. And some of it may be a common cold or other viral infection, which also spread more easily in the dry season. Most harmattan catarrh is not dangerous and settles with simple care. Saline nasal sprays or drops help keep the nose moist, and over-the-counter antihistamines from a registered pharmacist can ease the allergic type. See our allergic rhinitis page to tell the difference, and our related guide on antihistamines in Nigeria for what to know before buying.
| Symptom pattern | More likely | What often helps |
|---|---|---|
| Sneezing, itchy nose, watery eyes, no fever | Allergic rhinitis (dust) | Antihistamine, saline spray, avoid dust |
| Runny nose with body aches, sore throat, mild fever | Common cold (viral) | Rest, fluids, paracetamol; usually clears in a week |
| Dry, crusty, slightly blocked nose only | Dryness irritation | Saline drops, more water, humidify the room |
Dry skin and cracked lips
The dryness of harmattan strips moisture from your skin, leaving it ashy, tight, itchy, and prone to cracking — especially on the hands, feet, elbows, and lips. Children and older adults feel it most. People with eczema or sensitive skin often see flare-ups during these months. The fix is to lock in moisture rather than chase it after the damage is done.
- Apply a thick moisturiser, petroleum jelly, or shea butter (ori) right after bathing while the skin is still damp.
- Bathe with lukewarm rather than very hot water, and avoid harsh, drying soaps.
- Use a lip balm often, and resist licking your lips — it makes cracking worse.
- Drink water regularly through the day even when you do not feel thirsty.
- Cover up against the wind and dust with light long sleeves, a scarf, or a face covering outdoors.
Dry, itchy eyes
Harmattan dust and dryness commonly cause red, gritty, itchy, or watery eyes — it can feel like sand is in them. Lubricating eye drops (artificial tears) can soothe this, but use them safely: do not share eye drops, wash your hands before use, and stop and see a doctor if symptoms worsen. Avoid rubbing your eyes, as this can scratch the surface and worsen redness. Our guide on the safe use of eye drops explains how to use them correctly. Be cautious about so-called multipurpose eye drops sold in the market; check that any product is NAFDAC-registered, and never use eye drops meant for redness as a daily habit without advice.
See someone if eye symptoms are severe
Mild dry eyes usually settle with drops and rest. But see a doctor promptly for eye pain, sudden change or loss of vision, a lot of yellow or green discharge, marked light sensitivity, or one painful red eye — these can signal infection or another problem that drops alone will not fix.
Simple habits for the whole season
A few everyday habits cover most of harmattan health in Nigeria at once. Keep your home and bedding free of settled dust by dusting with a damp cloth rather than a dry one, which just throws dust into the air. Keep windows closed during the dustiest, haziest hours. Stay well hydrated. Use a face covering on dusty days, especially if you have asthma or allergies. And if you take any controller medicine — for asthma, allergies, or a chronic condition — make sure you have enough to last the season. If you run low, you can arrange an e-prescription and medicine delivery through GoDoctor rather than risk going without.
Harmattan health concerns rarely need emergency care, but they should not be ignored either — uncontrolled asthma, a chest infection, or an eye problem can quietly get worse. If your symptoms are not improving with simple care, are getting worse, or are stopping you from sleeping, working, or breathing comfortably, speak to an MDCN-verified doctor. On GoDoctor you can consult by video, audio or chat from home, get an e-prescription where appropriate, and order any lab tests or medicines you need.
FAQ
Is harmattan catarrh contagious? Catarrh caused by dust or allergy is not contagious — it is your nose reacting to irritants, not an infection. But if your runny nose comes with fever, body aches and a sore throat, it may be a viral cold, which can spread to others, so cover coughs and sneezes and wash your hands.
Why does my asthma get worse during harmattan? Cold, dry and dusty air is a well-known asthma trigger that can tighten and irritate your airways, so flares are common in this season. Using your preventer inhaler daily as prescribed, keeping your reliever close, and avoiding dusty outdoor air at the haziest times all help reduce attacks.
What is the best way to stop dry, ashy skin in harmattan? Apply a thick moisturiser, petroleum jelly or shea butter onto damp skin immediately after bathing to seal in moisture, bathe with lukewarm water, drink enough water, and protect your skin from the wind with covering clothing. If skin still cracks badly, becomes very itchy, or looks infected, see a doctor.
Can I just buy eye drops from the market for harmattan dry eyes? For mild dryness, plain lubricating drops (artificial tears) can help, but choose a NAFDAC-registered product, use clean hands, and never share drops. Avoid relying on redness-relief or unlabelled multipurpose drops without advice, and see a doctor if you have eye pain, vision changes, heavy discharge, or symptoms that keep getting worse.
