Autumn and the “September Spike” in asthma

10 September 2025

As summer fades and children return to school, asthma flare-ups become more common - a trend often called the “September Spike.”

Research from Asthma + Lung UK shows that children in England are over five times more likely to be admitted to hospital with an asthma attack in September compared with August. NHS England data revealed a 408% increase in admissions among 5 to 14 year olds at the start of the school year.

According to Dr Andy Whittamore, Clinical Lead at Asthma + Lung UK: “September can be a dangerous time for asthma, as colds and flu start to spread once children are back at school. This year’s spike could be worse than usual, with rising rates of measles and RSV putting more children at risk of serious breathing problems. That’s why it’s so important for families to be prepared.”

#AskAboutAsthma 2025 - education and action

From Monday 8 to Thursday 11 September 2025, the #AskAboutAsthma campaign returns for its ninth year. This year’s theme is:
“One year on from the National Child Mortality Database report: How can we prevent asthma deaths?”

The campaign will highlight preventable risks, share best practice, and provide practical steps to help keep children and young people safe timed ahead of week 38, when asthma attacks typically rise sharply.

The four key ‘asks’:

  1. Every child should have a personalised asthma action plan
  2. Inhaler technique should be checked and supported regularly
  3. Asthma reviews should take place every year and after every attack
  4. Air quality should be considered as part of asthma care.

How you can get involved:

  • Take part in webinars and the main campaign conference
  • Share campaign posters in schools, clinics, or workplaces
  • Spread the word on social media using #AskAboutAsthma
  • Access free resources, including films, podcasts, and fact sheets.

Helping families stay safe in September

Healthcare professionals, parents, and carers can all play a role in reducing asthma risks. Children who may need extra support include those who:

  • have been to hospital or urgent care in the past year
  • use more than one reliever inhaler a year
  • are overdue their annual review or a follow-up after an attack.

By checking inhaler technique, ensuring each child has an up-to-date asthma action plan and offering proactive support, we can significantly reduce the risk of hospital admissions this autumn.
