Keeping Older Adults Safe in Extreme Weather: Heat, Cold, and Storms

Why Older Adults Are More Vulnerable to Extreme Weather

The ability to regulate body temperature, to sweat effectively in heat and shiver effectively in cold, diminishes progressively with age. Older adults are also more likely to be taking medications that affect temperature regulation, to have underlying cardiovascular or respiratory conditions that are worsened by temperature extremes, to be less physically mobile and therefore less able to remove themselves from dangerous conditions, and to be more socially isolated, meaning that deteriorating health may not be noticed quickly.

The consequences are reflected in mortality data. Every significant heatwave and prolonged cold spell in the UK produces measurable excess deaths among older adults. Most of these deaths are preventable with adequate preparation, awareness, and social connection. This guide covers the practical steps that make a genuine difference in each category of extreme weather event.

Heatwave Safety

The key principle in hot weather is keeping core body temperature from rising to dangerous levels. The mechanisms available are: avoiding heat gain, active cooling, and maintaining hydration. Each needs practical implementation for older adults who may face specific barriers.

Keep the home cool during a heatwave. Close curtains and blinds on south and west-facing windows during the day to block solar heat gain. Open windows at night when outside temperatures drop. If the home has become hot despite these measures, spending the hottest part of the day in an air-conditioned space such as a shopping centre, library, or community centre is a worthwhile option that the NHS and local authorities actively promote during heat alerts.

Drink more water than usual during hot weather, even if you do not feel thirsty. Older adults have a reduced thirst response and are more prone to dehydration, which compounds the effects of heat. Keep a water bottle visible and within reach as a reminder to drink. Avoid alcohol and excessive caffeine, which contribute to dehydration.

Wear light, loose, light-coloured clothing. Take cool showers or baths, or at minimum apply cool, damp cloths to the neck, wrists, and armpits, where major blood vessels run close to the skin surface. Electric fans provide some comfort but are less effective than active cooling measures when temperatures exceed body temperature; in very high temperatures, they can accelerate dehydration by increasing sweat evaporation without adequately cooling.

Signs of heat exhaustion in older adults include: heavy sweating, pale or clammy skin, weakness, dizziness, nausea, and headache. Move the person to a cool environment, loosen clothing, apply cool water to the skin, and give fluids if they are conscious and able to swallow. Call 999 if symptoms do not improve within thirty minutes, or if the person becomes confused, loses consciousness, or stops sweating despite being very hot (a sign of heat stroke, which is an emergency).

Family members and neighbours should check on older adults they know during heatwaves. A daily check-in, by phone or in person, can identify deterioration before it becomes an emergency. Local authorities and Age UK operate specific welfare check schemes during heat alerts; contact them if you know of a vulnerable older adult who may not have adequate social contact.

Cold Weather Safety

Hypothermia, dangerous lowering of core body temperature, can develop indoors in older adults if the home is not adequately heated. Older adults may not notice they are becoming cold, and the early symptoms of hypothermia, confusion, slowness, and clumsiness, can be mistaken for other conditions. The risk is highest in January and February but exists throughout the winter months.

Keep the main living areas of the home heated to at least 18 degrees Celsius throughout the day when the weather is cold. The bedroom should be kept at least 18 degrees for sleeping, as body temperature drops during sleep and a cold bedroom increases the risk of heart attack and stroke in older adults. Use a room thermometer to monitor temperature rather than relying on how warm you feel.

Make sure the heating system is working before winter begins. Boiler services should be carried out annually; breakdown in cold weather can create rapid danger for an older adult living alone. Know how to contact an emergency plumber and keep a backup heat source such as an electric heater for the period when the heating is being repaired.

Winter Fuel Payment (available to older adults born before a date that changes annually), Cold Weather Payment (triggered during cold weather periods), and Warm Home Discount (available through some energy suppliers) are benefits that can reduce the financial barrier to adequate heating. Contact Citizens Advice or the local council if you are uncertain whether you or a relative is receiving all available benefits.

Storm Preparation

Before a storm is forecast, secure outdoor furniture and objects that could become projectiles. Stock an emergency kit including several days of any prescription medications, bottled water, non-perishable food, a torch and batteries, a battery-powered or hand-crank radio, and warm clothing and blankets in case of power failure. Charge phones and any backup power banks fully.

Register with your local power network operator's Priority Services Register if you or an older relative depends on electrically powered medical equipment, has a chronic illness, or has significant mobility limitations. Registration means the network operator will prioritise your restoration and make welfare calls during extended outages. Contact your energy supplier to register.

After a storm, check on older neighbours before venturing out yourself. Do not drive unless travel is essential. Report downed power lines to your network operator and do not approach them. If roads are flooded, do not walk or drive through floodwater: the depth can be deceptive and moving water is far stronger than it appears.
