Relief and prevention
Strength
Massage
Stretch
Hands and feet that are cold, sometimes going white then blue then red on exposure to cold. Peripheral blood vessels constrict more than they need to - and low muscle mass and inactivity reduce the heat production and the perfusion behind them.
How common: Raynaud affects 3-5% of the population; simple cold extremities are far more common
What it is
Cold extremities range from a nuisance to Raynaud's phenomenon, where cold or stress triggers an exaggerated constriction of small arteries in the fingers or toes: they go white, then blue as oxygen is used up, then red and painful as blood returns.
There are two important distinctions. Primary Raynaud's has no underlying disease and is common and benign. Secondary Raynaud's is associated with connective tissue disease and is more serious. And hand-arm vibration syndrome from occupational vibrating tools is a preventable occupational disease that looks similar and needs recognising.
What it feels like
- Hands and feet cold to touch and slow to warm up
- In Raynaud's, fingers or toes going white, then blue, then red on cold exposure
- Numbness and clumsiness during an attack, then throbbing and pain as they warm
- Triggered by cold, by taking something out of a freezer, and by stress
- Worse in winter and better in summer
What causes it
Most people have more than one of these at once, and they feed each other. Read the
list looking for the two or three that sound like your week rather than for the one
true answer — the ones that describe you are the ones worth acting on.
- Exaggerated peripheral vasoconstriction
- Small arteries in the fingers and toes constrict in response to cold to preserve core temperature. In Raynaud's that response is exaggerated and prolonged, producing the colour changes.
- Low muscle mass
- Muscle is the body's main heat generator. Less muscle means less heat production and a lower resting metabolic rate, so the periphery is sacrificed sooner to preserve the core.
- Inactivity
- Regular exercise improves endothelial function and peripheral perfusion. Being sedentary reduces both, independently of muscle mass.
- Hand-arm vibration syndrome
- Prolonged use of vibrating tools damages the small blood vessels and nerves in the fingers, producing vibration white finger. It is an occupational disease, it is preventable, and it is under-reported.
- Smoking
- Nicotine constricts peripheral blood vessels directly and damages endothelial function. It worsens every version of this problem.
- Connective tissue disease
- Scleroderma, lupus and other autoimmune conditions cause secondary Raynaud's, which is more severe and can cause tissue damage. Onset after thirty, severe attacks, or ulceration are the flags.
- Medications
- Beta blockers, some migraine medications and stimulants all constrict peripheral vessels and can cause or worsen it.
- Low body fat and low body weight
- Less insulation and often less muscle. It is one reason the condition is more common in slim young women.
- Thyroid underactivity and anaemia
- Both reduce heat production and are easily tested and treated causes of persistent cold intolerance.
- Stress
- Sympathetic activation constricts peripheral vessels directly, which is why emotional stress triggers Raynaud's attacks as reliably as cold does.
Who tends to get it
- Women, in whom primary Raynaud's is several times more common
- Anyone using vibrating tools regularly at work
- Smokers
- People with low muscle mass or low body weight
- Anyone with a connective tissue disease, or with new severe symptoms after thirty
What makes it worse, and what settles it
Makes it worse
- Cold exposure without gloves, and sudden temperature changes
- Smoking, which constricts vessels directly
- Vibrating tools, which cause permanent vascular damage over time
- Stress and anxiety, which trigger attacks independently of temperature
- Caffeine in some people, which constricts peripheral vessels
Settles it
- Regular exercise, which improves endothelial function and peripheral perfusion
- Building muscle mass, which is the body's heat source
- Keeping the core warm, not just the extremities - the body sacrifices the periphery to protect the core
- Gloves and warm layers before going out rather than after getting cold
- Stopping smoking, and reducing vibrating tool exposure with proper equipment and rotation
What actually helps
The short version: Peripheral vasoconstriction; low muscle mass and inactivity reduce peripheral perfusion
Strength work: Hands, Fingers, Forearms, Grip; Legs: Calves; Full Body
Stretching: Hands, Fingers, Wrists; Feet, Toes, Ankles
Massage: Hands, Fingers; Feet, Toes, Ankles
Also worth doing: Layering; avoid nicotine; warm-up before cold exposure
What the evidence says: Exercise improves peripheral perfusion. Massage gives short-term warming. Neither cures Raynaud.

Color change through white-blue-red with pain, or ulceration at the fingertips, needs rheumatology - it can signal connective tissue disease
And whatever the body part: chest pain or unusual breathlessness on
exertion; a fever alongside the pain; unexplained weight loss; pain that is constant and
unrelated to how you move; new numbness, weakness or loss of bladder or bowel control; or
one calf that is swollen, warm and painful. Any of those, stop and get assessed.
How it usually goes
Primary Raynaud's is a lifelong nuisance rather than a danger, and exercise, warmth and stopping smoking manage it well for most people. Vibration-induced disease is permanent, which makes prevention through tool selection, anti-vibration gloves and exposure limits the only real answer. New, severe or one-sided symptoms, attacks starting after thirty, or any skin ulceration on the fingers needs medical assessment for an underlying connective tissue disease.
