Hello,
actually it is not possible to not catch a cold even though not going into the blue temperature zone.

My clothing (status worn):

• skate helmet
• firefighter jacket
• hunter vest
• hunter pants
• working boots

Please review and adapt your temperature system so that only if you get into the blue temperature zone for too long you will catch a cold.
I also grow and eat fresh food all the time but the curing effect on the immune system is not comparable to the usage of vitamin pills.
This should be reviewed too.

TIA
