To keep a bedridden person warm, hold in their own body heat rather than adding hot devices. Keep the room at least 68 to 70°F, use several light layers of breathable bedding, cover the head, neck and feet, keep skin and sheets dry, and uncover only one area at a time when repositioning. Use heating devices only to prewarm the bed, never against skin.

A person with dementia may not notice or say they are cold, may forget to dress for the weather, and may wander outdoors. Keep their main rooms at 64 to 70°F or warmer, dress them in thin layers, check warmth at the back of the neck, supervise any heating device closely, plan for winter wandering and learn the signs of hypothermia.

An arm or leg on the side affected by a stroke often feels cold, and may measure colder, because the stroke disrupts the nerve signals that control blood vessel tone in that limb, reducing skin blood flow. Sensation can also change, so the limb may feel cold yet not sense heat. Warm it gently with layers, and never put direct heat on it.

Partly. Many people with arthritis or fibromyalgia say cold, damp weather makes their pain worse, and some studies find a real but modest link with humidity, wind and low air pressure. Temperature itself shows little consistent effect, and several large studies found no link at all. Your own pattern matters more than the average, and staying warm and active can help comfort.

Cold hands and feet are common in POTS because the autonomic nervous system, which controls blood vessels and body temperature, does not adjust normally. Blood tends to pool in the lower body when upright, leaving hands and feet cold, pale or purple. Many people swing between too hot and too cold, so the aim is gentle, adjustable warmth that avoids overheating.

Feeling cold is common with Parkinson's because the disease affects the autonomic nervous system, which controls sweating, blood vessel tone and other parts of temperature regulation. Many people notice cold hands, feet or legs, or feel too cold or too hot when others feel fine. Steady layering, a warm home, movement and careful use of heat sources help most.

Cold weather can make some MS symptoms temporarily worse, most often muscle stiffness, spasms, fatigue and walking. Cold sensitivity is less common than heat sensitivity in MS, and the change usually fades once you warm up again. The practical goal is to stay steadily warm with layers and a warm home, while protecting skin that may not feel heat properly.

Some people say they feel colder on Ozempic, Wegovy and other GLP-1 medications, but the US prescribing information for Ozempic and Wegovy does not list feeling cold or chills as a side effect. Eating less and losing body fat are plausible contributors, because both are linked to lower heat production or less insulation. Cold that is persistent or extreme deserves a check with your clinician.

Cold sensitivity during chemotherapy is most closely linked to oxaliplatin, which can make cold drinks, cold air and cold surfaces trigger tingling, numbness, cramping or throat tightness, often within hours of an infusion and for several days afterward. It usually fades after treatment ends. Room temperature drinks, gloves, scarves and layers help, and a fever during chemotherapy always needs an immediate call to your care team.

Cold weather can make a residual limb painful, change how the socket fits as limb volume shifts, and trap sweat when you move from the cold into heated rooms. Keep the limb covered and dry, carry extra prosthetic socks, check your skin every morning and night, and keep batteries warm. Never put heat directly on skin with reduced sensation.

To stay warm in a wheelchair, wear loose layers of wool or synthetic fabric, add a hat, warm socks and lined waterproof boots, and cover your lap and legs with a wheelchair poncho or zippered blanket. Use gloves that still grip the push rims. Charge power chairs every night, and keep heat sources off skin you cannot feel well.

After a spinal cord injury, especially at or above T6, the brain loses much of its connection to the skin, blood vessels and sweat glands below the injury. Shivering and sweating work only above that level, so body temperature tends to drift with the room or the weather. This is called poikilothermia. Managing it means controlling the environment, dressing well and avoiding direct heat sources.

Many health conditions and disabilities change how the body makes heat, holds on to it or senses it. Nerve damage, poor circulation, numb skin, some medicines and moving less all play a part. The safest approach is similar across conditions: keep the home warm, hold in body heat with layers, keep direct heat off skin that cannot feel it, eat and drink regularly, and know the signs of hypothermia.
