Seasonal health advice
Weather and season affect health in predictable ways — cold snaps make heart and lung conditions worse, hot weather is dangerous for older people and babies, spring and summer bring hay fever, and winter brings flu, colds and norovirus. A few sensible steps at the right time of year help you stay well.
Looking after yourself
- Autumn/winter: flu and COVID-19 vaccines if you are eligible; keep the main living room around 18–21°C; check on older neighbours in cold snaps
- Spring/summer: antihistamines for hay fever; sun cream (SPF 30+ minimum) and cover up in the middle of the day; extra fluids in the heat
- Norovirus season (winter): stay off work or school for 48 hours after symptoms stop; wash hands thoroughly
- Any season: keep a small first-aid kit and current pain relief at home
When to get medical help
Use NHS 111 online, call 111, or contact your GP if:
- An older person becomes confused, drowsy or stops drinking in a hot or cold spell
- A child’s fever is not settling with the usual self-care
- Someone with a long-term heart or lung condition finds their symptoms getting worse
Call 999 or go to A&E if someone has heat stroke (very hot, confused, seizures or unconsciousness), severe hypothermia (very cold, shivering has stopped, drowsy), or is having severe difficulty breathing.
