Waar komen trillende handen vandaan?
Trillende handen komen vaak voor en kunnen verschillende oorzaken hebben. Zo kan het voorkomen bij overmatig gebruik van stimulerende middelen zoals cafeïne, nicotine of alcohol. Het trillen vermindert dan zelf naarmate de middelen uitwerken. Ook bij stress, angst of paniek kan het trillen verergeren.
