Sore Throat

What causes a sore throat?

Most sore throats are caused by viral infections, such as the common cold or flu, and often come with other symptoms like a runny nose, cough or mild fever. Because they are viral, antibiotics do not help and the body clears them on its own, usually within a week.

Less commonly, a sore throat is caused by a bacterial infection, most notably strep throat. Other causes include irritation from smoke or dry air, allergies, acid reflux, and overusing the voice. Identifying the likely cause helps guide whether home care is enough or a doctor's visit is needed.

Soothing a sore throat at home

Most sore throats can be managed comfortably at home while the body recovers. Helpful measures include:

• •Resting and drinking plenty of fluids
• •Over-the-counter painkillers such as paracetamol or ibuprofen
• •Warm drinks, or warm water with honey and lemon (not honey for babies under one year)
• •Gargling with warm salty water (for adults and older children)
• •Sucking on lozenges or hard sweets to keep the throat moist
• •Avoiding smoke and other irritants

Viral versus bacterial (strep)

It can be hard to tell a viral sore throat from a bacterial one like strep, but some features make strep more likely: a sudden, severe sore throat without a cough, fever, swollen tender neck glands, and white patches on the tonsils. Strep is more common in children.

This distinction matters because strep throat may benefit from antibiotics, while viral sore throats do not. However, only a doctor can diagnose strep, sometimes with a throat swab. You should not take leftover antibiotics or pressure for them, as they do not help viral infections and overuse causes resistance.

Preventing sore throats

Many sore throats come from contagious infections, so the same steps that prevent colds and flu help: washing your hands regularly, avoiding close contact with people who are unwell, not sharing cups or utensils, and staying up to date with relevant vaccinations such as the flu jab.

For sore throats from irritation rather than infection, avoiding smoke, staying hydrated, and addressing causes like acid reflux or dry indoor air can reduce how often they occur.

Home remedies that actually help

Because most sore throats are viral and clear on their own, the goal of treatment is to ease discomfort while your body recovers, and several simple home remedies are genuinely effective. Staying well hydrated keeps the throat moist and soothes irritation, and warm drinks can be particularly comforting. A traditional remedy of warm water with honey and lemon is soothing and popular, though honey should never be given to babies under one year.

Gargling with warm salty water — about half a teaspoon of salt in a glass of warm water — can reduce discomfort for adults and older children, and is a cheap, safe option. Sucking on lozenges, hard sweets or ice helps keep the throat moist and stimulates saliva. Over-the-counter pain relievers such as paracetamol or ibuprofen are effective for the pain and any accompanying fever, used as directed.

It also helps to rest your voice, avoid smoke and other irritants, and keep indoor air from becoming too dry. These measures will not shorten a viral infection, but they make the days while it passes far more comfortable. If a sore throat is severe, lasts beyond about a week, or comes with warning signs, it is worth seeing a doctor rather than relying on home remedies alone.

Tonsillitis and recurring sore throats

Sometimes a sore throat is centred on the tonsils, the two soft pads of tissue at the back of the throat, a condition called tonsillitis. It causes a sore throat along with red, swollen tonsils, sometimes with white patches, pain on swallowing, and swollen glands in the neck. Like other sore throats, tonsillitis is most often viral and settles on its own, though some cases are bacterial and may benefit from antibiotics after assessment by a doctor.

Some people, particularly children, experience recurring tonsillitis or frequent sore throats. While each episode is usually managed the same way, repeated severe episodes that significantly disrupt life are worth discussing with a doctor, who can advise on whether any further assessment or treatment is appropriate.

Most recurring sore throats, however, are simply due to repeated common viral infections, especially in children who are building their immunity and are frequently exposed to bugs at school or nursery. Good hand hygiene, not sharing cups or utensils, and general measures to avoid infections all help reduce how often they occur.
