4. Cool your hands in hot weather.
If your veins swell due to the heat, wash your hands with cold water or stay in a cool place for a while.
5. Cover up if desired.
Long sleeves, bracelets, or watches can be distracting. Keeping your arms at heart level also reduces blood pooling.
6. Medical interventions (cosmetic solutions)
If the aesthetic problem is significant, the following measures may be considered:
Sclerotherapy  — injection of a solution that shrinks the vein.
Laser therapy  : Light that causes the vein to shrink.
Dermal fillers  — thicken the skin on the hands and hide veins.
Such procedures should only be performed by a qualified professional.
