Visible blue veins on your hands are usually harmless and caused by aging, skin type, or activity. Athletes and pregnant women often have more prominent veins due to increased blood flow.
However, if veins come with pain, swelling, or redness, it could signal health issues like varicose veins or blood clots. Staying active, avoiding long periods of sitting, and not smoking can help maintain healthy veins.
If symptoms worsen, consult a healthcare professional. Visible veins are often normal, but monitoring changes is important.
