Hot days can be wonderfully social and active—but they also bring a unique set of challenges for people in their mid-60s and beyond. Below is a practical, evidence-based guide you can publish as-is (or adapt to your voice) that pairs each summer ailment with simple, actionable steps for prevention or relief.

1. Heat Cramps, Heat Exhaustion & Heat Stroke

Why they happen

Ageing skin sweats less and circulatory reflexes slow down, so the body sheds heat more sluggishly.

Action Plan

What to Do	Details
Schedule hydration, don’t wait for thirst	Aim for 150–250 ml (½–1 cup) water every 20–30 minutes outdoors. Include an oral rehydration drink or a low-sugar sports beverage once or twice daily if sweating heavily.
Use the “20-20 rule”	For garden work or walks, spend no more than 20 minutes in direct sun, then cool indoors or in shade for 20 minutes.
Know emergency signs	Confusion, hot/dry skin, or a core temp ≥ 40 °C (104 °F) warrant a 999 call—cool with wet clothes or a cool bath while awaiting help.

2. Dehydration & Electrolyte Imbalance

Why they happen

Thirst perception blunts with age; diuretics, laxatives, or SGLT-2 diabetes drugs accelerate fluid loss.

Action Plan

Morning “baseline” test: Check urine colour after breakfast; if it’s darker than pale straw, start extra fluids early.
Smart salt: Pair water with salty snacks or a pinch of table salt in juice to keep sodium from plunging (unless on a salt-restricted diet).
Medication review: Ask the doctor whether summer warrants dose tweaks for diuretics, ACE inhibitors, or lithium.

3. Heart Strain & Blood-Pressure Swings

Why they happen

Heat causes peripheral vasodilation—blood pools in the limbs, lowering effective circulating volume and BP.

Action Plan

Rise slowly: Pause seated for 60 seconds before standing to prevent “heat syncope.”
Compression stockings for the win: Light-grade (15–20 mm Hg) stockings can curb pooling if tolerated.
Daily weight & symptom log: Sudden 1–2 kg gain, ankle swelling, or worsening breathlessness signal heart-failure flare; call the care team promptly.

4. Breathing Troubles & Poor Air Quality

Why they happen

Ozone, wildfire smoke, and Saharan dust peaks often accompany heat waves, irritating lungs.

Action Plan

Strategy	How-To
Check the AQI before outings	Free apps like AirNow or local meteorology sites provide real-time Air Quality Index; keep outdoor exercise for AQI < 100.
Create a “clean-air room”	Run a portable HEPA filter in one closed room; spend the hottest, smoggiest hours there.
Have a “rescue bundle” ready	Ensure inhalers aren’t expired, speak with the GP about a written COPD/asthma action plan, and refill steroids well before summer.

5. Kidney & Urinary Complaints

Why they happen

Concentrated urine fosters infection and stone formation; dehydration can tip vulnerable kidneys into injury.

Action Plan

Target 1.5–2 litres urine output/day: Practical cue is needing to void every 2–4 hours while awake.
Fruits beat fizz: Citrus and melon boost citrate (stone inhibitor) and fluids without the sodium of sodas.
Prompt UTI checks: Unexplained confusion, falls, or fever in older adults may be a “silent” UTI—seek a urine test quickly.

6. Skin & Eye Hazards

Why they happen

Thinner dermis, photosensitising meds, and lifetime UV accumulation raise risk.

Action Plan

SPF 30+ broad-spectrum sunscreen reapplied every two hours (more if sweating or swimming).
Lightweight, long-sleeved UPF clothing—loose linen or modern sun-protective fabrics keep skin cooler than short sleeves alone.
Hat + wrap-around shades with UV 400 lenses to shield cataract-prone lenses and retina.

7. Medication Mishaps

Why they happen

Anticholinergics, tricyclics, some antihistamines and antipsychotics suppress sweat or thirst; insulin loses potency in heat.

Action Plan

“Cool-cab” storage: Keep medicines between 15 °C and 25 °C (59–77 °F); use insulated pouches during travel.
Summer med check-up: Ask the pharmacist which prescriptions can impair heat tolerance; explore alternatives where possible.
Set phone alarms: Regular hydration & dose reminders help when cognitive or memory issues loom.

8. Mosquito-borne Illness (e.g., West Nile Virus)

Why they happen

Older immune systems handle arboviral infections less robustly, increasing severe neurologic outcomes.

Action Plan

Picaridin, or oil-of-lemon-eucalyptus repellents on exposed skin from dusk to dawn.
“Tip-and-toss” routine: Empty standing water in flowerpots, buckets, birdbaths weekly.
Screen doors & nets: Repair tears to keep night-biters out of the bedroom.

9. Food- & Water-borne Bugs

Why they happen

Bacteria multiply fastest between 5 °C and 60 °C (40–140 °F)—exactly picnic weather.

Action Plan

Two-hour rule: Refrigerate leftovers within 120 minutes (60 minutes if ambient ≥ 32 °C/90 °F).
Separate coolers: One for drinks (opened often) and one for perishable foods.
Consider bottled water on trips: Weakened stomach acid in elders means even mild contamination can cause severe gastroenteritis.

Quick-Reference Cheat Sheet

Ailment	Top 1–2 Preventive Moves
Heat illnesses	Scheduled fluids; 20-20 sun/cool cycle
Dehydration	Morning urine check; add salty snack
Heart strain	Slow posture changes; light compression socks
Respiratory flares	Track AQI; HEPA “clean room”
Kidney issues	1.5–2 L urine goal; citrus intake
Skin/eyes	SPF 30+, UPF clothing, UV 400 shades
Med complications	Summer pharmacy review; cool med storage
Mosquito disease	Picaridin; eliminate standing water
Food poisoning	Two-hour fridge rule; split coolers

Final Thoughts

Summer ailments aren’t a foregone conclusion of ageing—they’re largely preventable with a proactive routine: hydrate on a schedule, check the weather and air quality apps, dress for UV protection, and review medications at the start of every summer.
