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.

Yes, POTS can cause cold hands and cold feet, because the autonomic nervous system that controls blood vessels and body temperature does not adjust normally. Blood pools in the lower body when you stand, so less warm blood reaches the hands and feet, which can look pale or purple. Many people also swing between hot and cold, so gentle, adjustable warmth works best.

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.

Ozempic, Wegovy, Mounjaro and Zepbound do not list feeling cold or chills as a side effect in their US prescribing information, yet many people say they feel colder while taking them. Eating less and losing body fat are the most plausible reasons, since both are linked to lower heat production or less insulation. Persistent or extreme cold deserves a check with your clinician.

Oxaliplatin cold sensitivity usually starts within hours to 2 days after a dose and fades within 14 days, according to the FDA label, but it often returns with each dose and can last longer as cycles add up. Cold drinks, cold air and cold metal are the usual triggers. Room temperature drinks, gloves and a scarf help, and fever during chemotherapy needs an immediate call.

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.
