Medical devices, heating, refrigeration and communications lose reliability.
Health, First Aid & Hygiene

Power loss, water failure, medicine disruption and unsafe heating can turn manageable health needs into emergencies. Build the household medical layer before the system around you becomes harder to reach.
What changes as an outage gets longer
Falls, charging and communications become immediate issues.
Homes, medicines and devices may leave normal operating conditions.
Water, toilets, waste and handwashing become harder to sustain.
Medicine, powered care and access to services become the dominant risk.

Open guide →HEALTH CONTINUITY
Protect ordinary health needs when infrastructure becomes unreliable
A prolonged outage can turn routine needs into urgent ones. Prescription schedules, powered equipment, safe food, clean water, sleep and temperature control may all become harder to maintain while local services are under pressure. The most useful preparation is therefore continuity: know which needs cannot be delayed, what equipment depends on electricity and which contacts or records should be available offline.
Household planning should support professional care rather than try to replace it. Keep an accurate list of important medicines, relevant conditions, allergies and emergency contacts. Where storage, missed doses or backup supplies matter, follow advice from the relevant clinician or pharmacist rather than improvising during a disruption.
Prevent secondary problems
Blackouts and service failures can create risks that are not caused by AI at all: carbon monoxide from unsafe heating, spoiled food, dehydration, heat, cold, poor hygiene and exhaustion. The guides in this section focus on those practical failure points and on recognising when home is no longer the safer place to remain.
In a real emergency, follow local health guidance and emergency services. These pages are preparation material, not diagnosis or treatment.
Make the health plan visible to more than one person
Critical information should not live only in one person's phone or memory. Keep a concise written record of important contacts, current medicines, allergies, equipment dependencies and any information a household member may need if the usual organiser is unavailable.
Check the plan when prescriptions, care needs or equipment change. The aim is not to create a medical file at home; it is to make sure ordinary continuity does not collapse because one device, person or account becomes unavailable.
Use the section as a dependency map
The guides are organised around the systems a household may depend on during disruption. Start with the topic most relevant to the household and follow its links into power, water, communications and evacuation where those dependencies overlap.
