sinus infection travel health tips

Overview

A sinus infection (also called sinusitis) is an inflammation of the air-filled spaces around your nose, eyes, and forehead. It often follows a cold and can cause pain, a blocked nose, and mucus that will not drain easily.

Sinus infections are very common. Most people have at least one in their lifetime, often after a cold or allergy flare-up.

Anyone can get a sinus infection, but you are more likely to develop one if you have allergies, asthma, a weakened immune system, or if you smoke.

Symptoms

Common symptoms

• Facial pain or pressure around the nose, cheeks, or forehead
• A blocked or stuffy nose
• Thick yellow or green nasal discharge
• A reduced sense of smell
• A cough that often gets worse at night
• Headache or a feeling of fullness in the head

Symptoms in children

• Irritability or fussiness
• A runny nose or daytime cough lasting more than 10 days
• Low-grade fever
• Tugging at the ear or trouble sleeping

Symptoms in older adults

• Fatigue or confusion may be more noticeable than pain
• Less fever, but more general weakness
• Increased risk of balance problems if the inner ear is affected

Causes

Main causes

• Viral infections, such as a common cold
• Bacterial infection, which may develop if a viral infection does not clear
• Allergies, which can cause your sinus tissue to swell and trap mucus
• Nasal polyps or a deviated septum that block normal drainage

Risk factors

• Recent upper respiratory infection
• Allergic rhinitis (hay fever)
• Asthma or immune system problems
• Smoking or exposure to secondhand smoke
• Air travel, especially if you fly with a cold or nasal congestion
• Changes in air pressure when taking off or landing

When to see a doctor

See a doctor urgently if:

• Call your local emergency number right away if you have any of the emergency symptoms listed above.
• Seek same-day or urgent care if symptoms are severe, high fever is present, or you have sudden worsening after improvement.

Book a routine appointment if:

• Make a non-urgent appointment if your symptoms last longer than 10 days without improving.
• If you get sinus infections often (more than 4 a year) or they last more than 12 weeks, talk to your doctor about chronic sinusitis.

Diagnosis

A doctor usually makes the diagnosis from your symptoms and a physical exam. They may gently press on your face to check for tenderness, or look inside your nose with a light.

Tests that may be done

• Most cases do not need any tests.
• If you have frequent or severe infections, your doctor may recommend a CT scan or an endoscopic examination, where a thin tube with a camera is passed gently into your nose.

What to expect at your appointment

Your doctor will ask about your symptoms, how long they have lasted, any recent travel, and your general health. The visit usually takes only 15 to 20 minutes, and you will leave with clear next steps.

Treatment

Treatment depends on the cause. For viral sinus infections, self-care and symptom relief are enough. For bacterial infections, your doctor may decide antibiotics are appropriate. If you travel frequently, you can plan ahead to make flying easier.

Self-care at home

• Rest and sleep to help your body recover, especially before or during travel.
• Drink plenty of water to keep mucus thin and draining.
• Breathe in steam from a hot shower or a bowl of warm water to moisten your nasal passages.
• Use a warm compress over your face to soothe pain.
• Consider using a saline nasal rinse to gently clear your nose — ask your pharmacist which products are suitable.
• If you must fly, use a saline decongestant spray shortly before take-off and landing to help equalise pressure (ask your healthcare provider if this is safe for you).

Medical treatments

For bacterial sinus infections, a doctor may prescribe a short course of antibiotics. Over-the-counter pain relievers and fever reducers can help you feel better, but always check with your pharmacist or doctor for the right choice and dose. Corticosteroid nasal sprays may be recommended for swelling, but these are prescription-only and require medical advice.

When is surgery considered?

Surgery is rarely needed. If you have chronic sinusitis that does not improve with medication, or if you have a structural problem such as nasal polyps, an ear, nose, and throat specialist may discuss surgical options to open blocked drainage.

Living with this condition

When you are travelling with a sinus infection, plan ahead: carry tissues, a small water bottle, and a saline spray. Avoid flying if you have a very blocked nose or fever, if possible. If you must fly, talk to your doctor about ways to reduce pressure pain.

Lifestyle tips

• Wash your hands often, especially after touching your face or tissues.
• Avoid smoke and strong irritants that can make congestion worse.
• In hotel rooms or at home, use a humidifier or sit in a steamy bathroom to keep your sinuses moist.

Diet and exercise

Drink warm fluids like herbal tea or clear soups. Eat a balanced diet with fruits and vegetables to support your immune system. Gentle exercise, like walking, is fine if you feel up to it, but avoid heavy exertion while symptomatic.

Mental health and emotional wellbeing

Feeling unwell can make you feel frustrated, anxious, or low, especially if travel plans are affected. Give yourself permission to rest. If you feel overwhelmed while travelling, take a break in a quiet place; mental strain can make symptoms feel worse.

Prevention

You cannot always prevent sinus infections, but you can reduce your risk. Practise good hand hygiene, manage allergies, avoid smoking, and stay hydrated. When travelling, try to avoid flying with a heavy cold; if you must, use a saline spray and drink water before and during the flight.

Vaccines

Vaccines against influenza (flu) and COVID-19 can reduce respiratory infections that sometimes lead to sinusitis. Ask your healthcare provider about recommended vaccinations before travelling.

Screening programmes

There is no routine screening test for sinus infection. If you have frequent episodes, your doctor may evaluate for underlying causes like allergies or structural problems.

Complications

If left untreated

• Very rarely, a bacterial sinus infection can spread to nearby tissues, such as the eyes, bones, or brain — this is a medical emergency.
• Chronic sinusitis can develop, causing long-term congestion, facial pain, and reduced sense of smell.
• Untreated allergies can cause ongoing inflammation that makes sinus infections more likely.

Long-term outlook

The vast majority of sinus infections clear without any permanent problem. Even chronic cases can usually be managed well with the right treatment and good self-care. Most people return to their normal activities within a few weeks.
