🌡️ Hot weather and your lungs – what you need to know
When temperatures rise above 25°C, hot weather can start to affect your lung health. If you live with asthma or COPD, taking steps to stay well in the heat could help reduce flare-ups, prevent asthma attacks, and even avoid trips to your GP or hospital.
Not everyone with a lung condition is affected in the same way, but for some people, hot weather can make symptoms worse. Here’s why:
☀️ Hot, humid air can make breathing feel harder and may increase symptoms like breathlessness and wheezing.
🌻 Higher pollen levels are common in warmer weather. If you also have hay fever, it could trigger or worsen your lung symptoms.
💙 Top tip: Stay cool, keep hydrated, and monitor your symptoms during hot spells. If you notice changes, follow your care plan and seek advice if needed.
