My fingers and toes get the frozen feeling and numb at ambient temperature of 20°c.

I was OK when I was young. It gets worse and worse (temperature tolerant) when I'm more than 25 years old. 28°c is considered cold for me (below 30°c and I need a blanket to sleep). As most indoor places in Malaysia are well air-conditioned, I get uncomfortable in many places. I'm not sure if this is the side effect of my harsh working area temperature of 40-50°c.

Anyone here facing the same problem?

Last time I tested myself with ice. Finger temperature failed to go back to normal after a specified period.
