  2. Raynaud’s syndrome

Raynaud’s syndrome

Raynaud’s syndrome is a condition that affects blood flow to certain parts of the body, usually the fingers and toes. When someone with Raynaud’s is exposed to cold temperatures or stress, small arteries in these areas can narrow and limit blood circulation. This causes the affected areas to become white or bluish and feel cold or numb. When blood flow returns, the skin may turn red and throb or tingle.

Though the exact cause of Raynaud’s syndrome is unknown, it is thought to be related to overactivity of the body's response to cold or stress. While the condition is more common in colder climates and among women, it can affect anyone. For many, symptoms are mild and manageable with lifestyle changes like dressing warmly and reducing stress. However, for others, medical treatment might be necessary.

Sometimes, Raynaud’s occurs on its own, but it can also be linked to other health issues. If symptoms are severe or interfere with daily life, it’s advised to seek medical advice to rule out any underlying conditions.
