Why do my hands and feet gets cold easily?

especially if the weather is cold or even just cool.
sometimes my hands are cold even when the weather is warm.
i'm a 23 year old female.

You might just have poor blood circulation. Hands and feet are prone to getting cold because they have more surface area, and the blood can't warm them as well. It's nothing to worry about, though, just make sure to wear gloves in cold weather.

You could have Raynaud's disease.

Raynaud's disease or syndrome is a disorder of blood circulation, mainly in the fingers and toes. It is of unknown cause and characterized by changes of the skin that are aggravated by exposure to cold: first, becoming white with numbness and pain as a result of inadequate oxygenation of the blood, then red/purple with a burning sensation. The sudden constriction of blood vessels causes decreased blood flow to the extremities and can, in extreme cases, lead to gangrene. Also called "white finger", "wax finger" or "dead finger".

You should check with your doctor the next time you see him/her.
It's not fatal but it would be nice to know.
