Ireland’s climate is changing. Summers are warmer, heavy rainfall events are more frequent, and the patterns that generations of Irish people grew up with are shifting. While climate change affects everyone, research consistently shows that older adults are among those most vulnerable to its health impacts — and understanding why can help you take practical steps to stay well.
TL;DR
- Older adults face higher health risks from heatwaves, poor air quality, and extreme weather events due to age-related changes in thermoregulation and chronic conditions
- Ireland experienced its joint-warmest year on record in 2023, with heatwave events becoming more common — preparation is essential
- Simple measures like staying hydrated, knowing your medication interactions with heat, and having an emergency plan can significantly reduce risk
- Mental health impacts of climate change — including eco-anxiety, displacement from flooding, and disrupted routines — are real and worth addressing
- Irish supports include HSE heatwave guidance, Met Éireann weather warnings, ALONE’s support line, and local authority climate adaptation plans
Why Older Adults Are More Vulnerable
This isn’t about frailty or decline — it’s about biology. As we age, our bodies become less efficient at regulating temperature. The ability to sweat decreases, blood vessels don’t dilate as readily, and the thirst mechanism becomes less reliable. These are normal changes, but they mean that extreme temperatures — whether hot or cold — pose a greater challenge.
Add in chronic conditions such as heart disease, diabetes, or respiratory illness — conditions that become more common after 50 — and the picture becomes more complex. Many common medications, including diuretics, beta-blockers, and antihistamines, can affect how your body handles heat. According to TILDA (The Irish Longitudinal Study on Ageing), over 60% of adults aged 50 and over in Ireland live with at least one chronic condition, making this a significant public health consideration.
Heatwaves: Ireland’s Growing Challenge
Ireland may not spring to mind when you think of heatwaves, but the data tells a different story. Met Éireann has recorded a clear upward trend in summer temperatures, and the EPA’s Climate Status Report for Ireland confirms that heatwave events are becoming more frequent. The summer of 2022 saw prolonged periods above 30°C in parts of the country — something that would have been almost unheard of a generation ago.
For older adults, even moderately high temperatures can trigger heat exhaustion or heatstroke, particularly if you live alone or have limited mobility. The HSE recommends the following during warm spells:
- Stay hydrated — drink water regularly, even if you don’t feel thirsty. Aim for 6–8 glasses a day, more in warm weather
- Keep your home cool — close curtains on sun-facing windows during the day, open windows at night when it’s cooler
- Avoid the midday sun — if you enjoy being outdoors, aim for morning or evening walks
- Check your medications — speak with your pharmacist about whether any of your medications affect heat tolerance or need different storage in warm weather
- Wear light, loose clothing — natural fabrics like cotton are best
- Know the signs — headache, dizziness, nausea, rapid pulse, and confusion can indicate heat-related illness. Seek help immediately
Air Quality and Respiratory Health
Climate change doesn’t just bring warmer temperatures — it affects the air we breathe. Higher temperatures increase ground-level ozone, extend the pollen season (bad news if you have hay fever or asthma), and can worsen air quality during dry spells. Ireland’s traditionally clean air is a national asset, but it isn’t immune to these changes.
If you have a respiratory condition such as COPD or asthma, it’s worth keeping an eye on the EPA’s air quality index (available at airquality.ie) and adjusting outdoor activities on poor air quality days. Having a reliever inhaler to hand and keeping windows closed during high-pollen periods are simple but effective steps.
Flooding, Storms, and Extreme Weather
Ireland has always had its share of wild weather, but the frequency and intensity of heavy rainfall events is increasing. Flooding can be devastating at any age, but for older adults it brings particular challenges: difficulty evacuating, disruption to medication access, damage to mobility aids or medical equipment, and the profound stress of displacement.
The OPW (Office of Public Works) and local authorities have been investing in flood defences, but individual preparedness matters too. Críonna Health recommends having an emergency plan that includes:
- A list of your medications, GP contact details, and next-of-kin information kept in a waterproof folder
- An emergency bag with essentials (medications, phone charger, warm layers, torch)
- Knowing your local authority’s emergency contacts
- Signing up for Met Éireann weather warnings via their app or website
- If you live alone, letting a neighbour or family member know your plan
The Mental Health Dimension
The psychological impact of climate change on older adults is often overlooked but very real. Research from the WHO highlights several pathways: the anxiety of watching familiar landscapes and seasons change, the stress and grief following extreme weather events, social isolation when bad weather prevents getting out, and the broader sense of loss that comes with environmental change.
For people who have spent decades in the same community, flooding or storm damage to local landmarks, churches, or gathering places can feel like a personal loss. If you’re experiencing climate-related worry or distress, it’s worth talking about it — with your GP, with friends, or through supports like the ALONE support line (0818 222 024) or Samaritans Ireland (116 123).
What Ireland Is Doing
Ireland’s Climate Action Plan commits to building resilience for vulnerable populations, including older adults. The HSE has developed heatwave guidance, and local authorities across the country are required to produce Climate Change Adaptation Strategies that specifically consider the needs of older people. The Age Friendly Ireland programme, active in every local authority area, provides an important channel for older adults’ voices to be heard in climate planning.
Under the Assisted Decision-Making (Capacity) Act 2015, you can also plan ahead by setting up an Enduring Power of Attorney or Advance Healthcare Directive — ensuring that if an emergency does arise, your wishes are respected and someone you trust can act on your behalf.
Practical Steps You Can Take Today
- Talk to your GP or pharmacist about how your medications interact with extreme temperatures
- Download the Met Éireann app and enable weather warning notifications
- Prepare an emergency kit — even a small bag with essentials can make a significant difference
- Stay connected — social networks are your best protection. Let neighbours know if you live alone; check in on others during extreme weather
- Engage locally — join your local Older People’s Council or Age Friendly Alliance to ensure older adults’ needs are part of climate planning
- Adapt your home — simple measures like reflective window film, draught-proofing, and energy-efficient heating reduce both your carbon footprint and your vulnerability
