Mantenere gli anziani al sicuro quando fa freddo: ipotermia interna, controllo dei vicini e aiuto per il riscaldamento¶

Cold weather is far more dangerous for older adults than most people realize, and much of the danger is indoors. An older person can develop hypothermia in a living room that feels merely chilly, because aging changes how the body senses cold, produces heat and holds on to it. Winter also brings falls on ice, heart strain, flu, carbon monoxide from poor heating, and the risk of being alone when something goes wrong.

This guide is for older adults, their families and their neighbors. It explains why cold is riskier with age, how to keep a home at a safe temperature, how to recognize indoor hypothermia, how to check on neighbors safely and kindly, and how to find help with heating costs in the United States, Canada, the United Kingdom and other countries. It also covers medication, food, falls, carbon monoxide and power outages. See pianificazione di emergenza per gli anziani for general planning.

1. Check the temperature in the room where the older person spends the day and in the bedroom. Aim for at least 18 degrees Celsius (64 degrees Fahrenheit) in living areas, and warmer if the person feels cold, is frail or is unwell. Move them to a warmer room or place if they cannot get comfortable.
2. Look for warning signs: cold skin, shivering or no shivering at all, drowsiness, slurred speech, confusion, slow movement or a puffy, pale face. If you see them, call your local emergency number (911 in the United States and Canada, 112 across the European Union, 999 in the United Kingdom). See numeri di emergenza.
3. Add layers, a hat, warm socks and blankets, and help the person to eat and drink something warm. Remove damp clothing and keep them out of drafts.
4. Check that a working carbon monoxide alarm and smoke alarm are in place, and that no grill, camp stove, generator or gas oven is being used for heat.
5. Check on neighbors who are older or alone, by phone or at the door, and agree on a daily check in during cold spells. Leave a number they can call.
6. If the power or heating fails, move the person to a warm relative's home, a warming center or a shelter early, rather than waiting until the house is very cold.

Why older adults are more at risk¶

Several changes with age make cold harder to handle. None of them is a fault or a failure. They are normal, and a few simple steps can protect against them.

• A weaker sense of cold. Older people often do not feel cold until their body temperature has fallen. They may say they are fine when they are not.
• Less body heat. Muscle mass and metabolism fall with age, so the body makes less heat. Thinner skin and less body fat give less insulation.
• Slower shivering. Shivering is the body's main way of making heat in the short term, and in older adults it can be weaker or may stop early.
• Poorer circulation. Narrowed blood vessels, heart disease, diabetes and certain medicines reduce blood flow to the skin and extremities.
• Medical conditions. Heart disease, lung disease, thyroid problems, diabetes, Parkinson's disease, dementia, stroke and arthritis all raise risk. Illness and infection can change temperature control.
• Medicines. Some medicines for sleep, anxiety, depression, allergies, high blood pressure and mental health affect how the body senses or handles temperature, and some cause dizziness or confusion.
• Limited mobility and isolation. People who cannot move easily, who live alone or who rarely go out may not notice a cold house, and they may not be able to get help.
• Cost worries. Many older adults keep heating low to save money, and some skip meals or medicine to pay for energy. This is a leading cause of cold related illness.
• Alcohol. A drink can feel warming but speeds heat loss.

Cold related deaths in winter are often due to heart attack, stroke and lung infection, not only hypothermia. Cold raises blood pressure and makes blood more likely to clot, so heart and circulation problems rise sharply in cold weather. The National Health Service (United Kingdom), the Centers for Disease Control and Prevention (United States) and Health Canada all warn about these indoor risks.

Indoor hypothermia¶

Hypothermia means the body's core temperature has dropped below 35 degrees Celsius (95 degrees Fahrenheit). It can occur indoors in a cool home, especially over several days, and it can build slowly so that no one notices. The person may seem tired, quiet or confused, and families may blame age or illness.

Warning signs¶

Because older adults may not shiver, absence of shivering does not mean they are fine. Look for other signs such as cold skin on the stomach or back, confusion, slow speech, unusual sleepiness or a strange change in behavior.

Cosa fare¶

1. Call your local emergency number if you see signs beyond mild shivering, or if the person is confused, very sleepy, unresponsive or not shivering despite feeling cold.
2. Move the person to a warm room if you can do so gently. Do not allow them to walk if they are weak.
3. Remove wet clothing and replace it with dry layers. Wrap them in blankets, with a hat or cloth around the head and neck, and put insulation under them.
4. Give warm, sweet, non alcoholic drinks if they are awake and can swallow. Do not give food or drink to someone who is drowsy.
5. Place warm, not hot, water bottles wrapped in cloth against the chest, armpits and groin. Do not use a hot bath, heating pad on bare skin, or a hair dryer.
6. Handle gently and do not rub the arms or legs.
7. Stay with them and check breathing. If they are unresponsive and not breathing normally, start CPR. See RCP.

Safe temperatures at home¶

Health agencies give guidance on indoor temperatures. The World Health Organization and many national health services suggest that living rooms be kept at about 18 degrees Celsius (64 degrees Fahrenheit) or higher for healthy adults. Older people, those who are unwell, and those who are not very active may need it a little warmer, such as 20 to 21 degrees Celsius (68 to 70 degrees Fahrenheit) in the room where they sit. Bedrooms are often advised at around 18 degrees Celsius (64 degrees Fahrenheit) or slightly cooler for sleep with warm bedding.

These figures are general. Use a simple room thermometer in the living area and in the bedroom, and do not trust how the room feels. A thermometer with large numbers helps people with poor sight.

Keeping a home warm without risk¶

• Heat the rooms that are used most, and close doors to others. It is better to heat one room well than to heat the whole house poorly.
• Stop drafts with draft excluders, tape and curtains. Keep curtains closed at dusk and open them during the day to let in sun.
• Use a thermostat set steadily, rather than turning heating on and off. Constant moderate heat is often cheaper than short bursts, and safer.
• Dress warmly indoors: several thin layers, a cardigan, socks, slippers, and a hat if the house is cold. Wear a hat in bed if needed.
• Use blankets and a hot water bottle wrapped in a cover, or a modern electric blanket that is in good condition and is used according to the instructions. Do not use an electric blanket that is old, frayed or damaged, and do not use one if the person is incontinent or has dementia without medical advice.
• Sit with the legs raised and covered, and avoid sitting still for long periods. Stand up and move every hour.
• Eat regular hot meals and warm drinks. Food gives the body fuel for heat.
• Avoid alcohol, which causes heat loss and increases the risk of falls.

Checking on neighbors¶

Many older adults live alone, and some have no family nearby. A simple check by a neighbor can be the difference between a minor problem and a tragedy. Cold snaps, storms and power outages are the times when checks matter most.

How to check in kindly¶

1. Make a plan before the weather turns. Knock, introduce yourself, and offer your phone number. Ask whether they would like a daily call or visit during cold weather, and who else should be contacted in a crisis.
2. Agree on a signal. For example, a blind raised in the morning, a phone call at a set time, or a card in the window. If the signal is missing, someone checks.
3. Call first if you can. A call lets the person speak without feeling intruded on, and you can tell if their speech is slurred or they are confused.
4. Visit in person during emergencies. Knock, wait patiently, and speak clearly. Some people take time to get to the door.
5. Ask open questions. How warm is the house? Do you have heat and power? Have you eaten today? Do you have your medicines? Have you fallen?
6. Look for signs. Is the house cold, with the heating off? Is mail or snow piling up? Are curtains still closed in the afternoon? Is there a smell of gas or smoke?
7. Offer practical help. Offer to shop, clear snow, collect medicine, charge a phone or move them to a warmer place.
8. Respect independence. Offer rather than insist, and avoid talking down to the person. Many people are proud, and they are more likely to accept help from someone who treats them as an equal.

If no one answers¶

• Call the person on the phone and any known contacts, such as family, a caregiver or a friend.
• Look through the window and listen from the door for sounds of distress, calls for help, or a television running all day.
• Check for a key holder or a spare key if you have been given one, but do not enter a home that smells of gas or smoke, or where you suspect carbon monoxide.
• If you are worried, call your local emergency number and ask for a welfare check. Tell them what you know: the person's age, health, how long since contact, and any signs.
• Do not break in unless you see someone in obvious trouble and cannot wait. Give details to the dispatcher first.

Community networks¶

Some neighborhoods run block captain programs, volunteer check in schemes and registries of residents who need support. See neighborhood CERT mutual aid block captain plan and vulnerable neighbor registry. Ask local government, senior centers, faith communities, libraries, and charities about check in services, meals delivered to the door, and winter outreach teams. In the United Kingdom, Age UK and local councils run schemes. In the United States and Canada, local Area Agencies on Aging and Meals on Wheels programs often include wellness checks.

Heating assistance programs by country¶

Money worries are a major reason older adults keep homes too cold. Help exists, but programs and rules change often, so check the current details with the official source. A phone call to a local senior center, community organization, or social services office is a good start. Never wait until the heat is cut off to ask for help.

In the United States¶

• Low Income Home Energy Assistance Program (LIHEAP). A federal program that helps eligible households pay heating and cooling bills, and in some places helps with emergency repairs and crisis situations. Apply through your state or local energy assistance office. Dialing 211 connects you to local services in many areas.
• Weatherization Assistance Program. Helps eligible households make homes more energy efficient through insulation, sealing and heating system repairs.
• Utility protections and payment plans. Many states restrict winter shutoffs for customers who are older or seriously ill, and many utilities offer budget billing, discounts and medical certificate programs. Call your utility before you fall behind and ask.
• Local help. Area Agencies on Aging, community action agencies, faith groups, the Salvation Army and similar charities often give emergency fuel or bill help.

In Canada¶

• Provinces and territories run their own programs, such as low income energy assistance, home energy efficiency grants, and winter heating benefits. Utility companies often run hardship funds. Check your provincial government website, your utility and local community services.
• Federal and provincial seniors benefits, tax credits and housing programs may offer support. Service Canada and your province can tell you which apply.
• Health Canada gives advice on cold weather safety and carbon monoxide.

In the United Kingdom¶

• Winter Fuel Payment and Cold Weather Payment. These government payments have eligibility rules that have changed in recent years, so check the current rules on the GOV.UK website.
• Warm Home Discount. A discount on electricity bills for eligible households, through participating suppliers.
• Priority Services Register. Free service from your energy supplier and network operator that gives extra support during power cuts to people who are older, disabled or who depend on medical equipment. Ask your supplier to add you.
• Energy efficiency and grants. Schemes and local authority programs help with insulation and heating upgrades.
• Charities such as Age UK, Citizens Advice and local councils give free advice on benefits and bills, and sometimes grants.

In Ireland, Australia, New Zealand and elsewhere¶

• Ireland offers a fuel allowance and other support through the Department of Social Protection, and the Sustainable Energy Authority of Ireland runs energy upgrade schemes.
• Australia has state based energy concessions and rebates for pensioners and seniors. Check your state government and energy retailer.
• New Zealand offers a Winter Energy Payment to eligible people and insulation programs through government agencies.
• In the European Union, support differs by country. Look for national or local heating allowances, social tariffs, and energy poverty measures. Your local municipality, social services and consumer advice center can help.
• In other countries, contact local government, social services, faith groups and charities. Even where no formal program exists, community groups often provide blankets, fuel and meals during cold spells.

Tips for getting help¶

1. Gather basic documents: ID, proof of income, recent energy bills and proof of age or disability.
2. Ask a trusted relative, neighbor or caseworker to help with forms.
3. Call your energy supplier before you miss payments and ask about hardship programs.
4. Apply early in the season, since funds can run out.
5. Beware of scams. Never give bank details to a caller or visitor who says they are from a heating assistance scheme, and do not pay up front for government grants. Use official websites and phone numbers.

Food, medicine and health in the cold¶

Food and fluids¶

Gli anziani potrebbero non avere sete o fame al freddo, ma il corpo ha comunque bisogno di carburante e liquidi. Preferisci pasti caldi regolari, zuppe e bevande calde e tieni in casa cibi non deperibili in caso di temporali. Prendi in considerazione la consegna dei pasti a domicilio se la spesa è difficile. Controllare che il frigorifero e il congelatore funzionino e che il cibo rimasto senza corrente sia sicuro. Vedere cibo avariato e interruzione di corrente del frigorifero.

Medicinali¶

• Tenere almeno una o due settimane di medicinali a casa in inverno, se il medico prescrittore lo consente, e tenere un elenco di ciò che si assume. Richiedi ricariche prima dei temporali.
• Scopri quali farmaci necessitano di refrigerazione, come l'insulina, e pianifica un piano per le interruzioni di corrente. Vedere farmaci sensibili alla temperatura in caso di interruzione di corrente.
• Mantenere una chiara routine terapeutica ed evitare dosi doppie o mancate. Vedere errori della polifarmacia e dell'organizzatore della pillola.
• Chiedi a un farmacista o a un medico se qualcuno dei tuoi medicinali ti rende più sensibile al freddo o ha maggiori probabilità di cadere.
• Ottieni i vaccini stagionali, come quello antinfluenzale e altri consigliati dal tuo servizio sanitario, per ridurre le malattie invernali.

Attrezzature mediche¶

Se qualcuno dipende dall'ossigeno, da un ventilatore, da una macchina CPAP, da un letto elettrico o da una macchina per dialisi, informa in anticipo il servizio di fornitura, tieni batterie o bombole di riserva e pianifica di trasferirti in un luogo sicuro in caso di interruzione della corrente. Vedere interruzione dell'alimentazione per concentratori di ossigeno, ventilatori e CPAP. Non fumare o usare mai fiamme libere vicino all'ossigeno.

Cadute, neve e ghiaccio¶

Le cadute sono la principale causa di infortuni negli anziani e il ghiaccio invernale ne aumenta il rischio. Un'anca rotta o un trauma cranico possono cambiare la vita di una persona anziana e le persone che assumono anticoagulanti possono sanguinare all'interno della testa anche dopo un lieve colpo. Resta in casa quando possibile nelle giornate ghiacciate, organizza le consegne e, se necessario, indossa stivali con una buona presa e un bastone con la punta del ghiaccio. Se avviene una caduta, leggi Scivolare sul ghiaccio: come cadere e quando rivolgersi alle cure e gli anziani si riprendono dalle cadute quando non sono in grado di stare in piedi.

Non lasciare che una persona anziana con una malattia cardiaca spali la neve. Vedere spalare la neve in sicurezzae organizzare l'aiuto per eliminare percorsi e passaggi.

Demenza e vagabondaggio nella stagione fredda¶

Le persone affette da demenza possono vagare all’aperto con abiti leggeri e perdersi o andare in ipotermia entro un’ora. Installa allarmi o campanelli alle porte, conserva una foto recente e un braccialetto identificativo e comunica ai vicini chi chiamare se vedono la persona fuori. Se qualcuno vaga con tempo gelido, chiama subito il numero di emergenza locale, perché il rischio aumenta rapidamente. Vedere anziano errante in condizioni climatiche gelide o ondate di caldo e demenza errante e senior scomparso.

Interruzioni di corrente e temporali invernali¶

Un'interruzione in inverno rappresenta un grave rischio per gli anziani. Pianifica prima della tempesta.

• Parla di cosa farai in caso di interruzione della corrente: dove andare, chi chiamare e come arrivarci.
• Tieni una radio a batteria, torce elettriche, batterie di riserva, un power bank per il telefono, vestiti caldi, coperte e un sacco a pelo.
• Tieni un elenco di medicinali, medici e contatti di emergenza nel portafoglio e sul frigorifero. Vedere generatore di carte di contatto di emergenza.
• Non utilizzare un generatore all'interno e installare in casa un allarme per il monossido di carbonio alimentato a batteria. Vedere sicurezza del generatore.
• Parti presto se la casa fa freddo. Non aspettare finché non è pericoloso.
• Dopo il temporale, controllare attentamente le tubazioni e il riscaldamento prima di ripristinare il normale calore. Vedere tempesta di ghiaccio, rami degli alberi e ripristino del calore in sicurezza e interruzioni elettriche invernali e blackout prolungati.

Checklist for a safe winter home¶

• Room thermometer in the living area and bedroom, set to at least 18 degrees Celsius (64 degrees Fahrenheit).
• Working carbon monoxide alarm and smoke alarm, tested this month.
• Heating serviced this year, and chimney or flue checked if used.
• Draft proofing, curtains, blankets, hat and warm socks ready.
• At least a week of food, and medicines refilled.
• Phone charged, list of contacts and a power bank.
• A neighbor or relative who will check in daily during cold weather.
• Details of heating assistance and the utility's priority list.
• A plan for where to go if the heat or power fails.
• Grip boots, ice tip cane, and help with snow and ice clearing.

Supporting a family member from a distance¶

Many families live far from their older relatives. You cannot check a thermostat from another city, but you can set up a system that gives early warning. Start with a conversation before winter about what the person wants and what worries them, and agree on a few routines that feel respectful rather than controlling.

• Arrange a regular call at a fixed time each day in cold weather, and agree what you will do if it is missed.
• Ask a trusted neighbor, friend or local volunteer to be a second contact, and give them your number.
• Consider a smart thermostat or a simple temperature sensor that sends an alert to your phone if the home falls below a set temperature. Ask the person for permission first, and explain what is being monitored.
• Consider a personal alarm or fall detector that can call for help, and check that it is charged and worn.
• Arrange grocery and medicine delivery, and meal services, so that the person does not have to go out on ice.
• Pay or help with energy bills if you can, and help to apply for assistance. Many older adults are reluctant to ask.
• Visit before the cold arrives to check alarms, draft proofing, heating, ice grips for boots and the stock of food and medicine.
• Keep contact details for the person's doctor, pharmacy and neighbors with you, and learn who holds a spare key.

If you cannot reach the person and are worried, call a neighbor first, then call your local emergency number and ask for a welfare check. Give the dispatcher the address, the person's age, any health conditions and the time of the last contact.

Domande frequenti¶

What temperature should an older adult keep their home?¶

Many health services advise at least 18 degrees Celsius (64 degrees Fahrenheit) in the rooms where people spend time, and a little warmer, around 20 to 21 degrees Celsius (68 to 70 degrees Fahrenheit), for people who are frail, unwell or not very active. Use a room thermometer rather than relying on how the room feels. Move the person to a warmer place if the home cannot be kept warm.

What are the signs of hypothermia in an older person?¶

Look for cold skin, tiredness, slurred speech, confusion, clumsiness, a puffy pale face, slow movement and slow breathing, and note that shivering may be weak or absent. Call your local emergency number if the person is confused, very drowsy or unresponsive. Warm them gently with dry layers and blankets while you wait.

How can I help an older neighbor without being intrusive?¶

Introduce yourself before bad weather, share your number, and offer a regular phone call or a signal such as a blind raised in the morning. Offer help with shopping, snow and warm meals, and let the person decide what they want. If you cannot reach them and you are worried, call your local emergency number and ask for a welfare check.

Where can I find help paying for heating?¶

Start with your energy supplier and your local senior center or social services office, which can point you to current programs. Examples include LIHEAP and weatherization in the United States, provincial energy programs in Canada, and Warm Home Discount, Cold Weather Payment and the Priority Services Register in the United Kingdom. Check the official government website for current rules, and do not give bank details to anyone who calls or visits unasked.
