I have the opposite problem. I bought a de-humidifier for it. It cost money, it benefits the entire house.
Nusa, gave you what be my first suggest. humidifier, or tray of water if heater nearby.
james_s would be the next -wear cotton. If you're doing the COVID stay-at-home thing, then make sure your bathrobe and pajamas are all cotton. none of this mixed fibers BS

cdev has a good suggestion an air ionzier. It is a negative ion generator. Not the other anti-static type they create that toxic type of oxygen..Not hard to build one either.
However, do keep keep near your work area. They also pull out even tiny dust and it is a pain to clean that type. If DIYing, include a positive, or is it a grounding collector next to, or a part of it.( Not sure how to build that part). IT pulls in most the the dust laden particles
-Several have suggested bare feet, another is is just a piece of metal, or aluminum plate on the floor where you place your feet. DO NOT ground that to building electrical earth, thoug. A "feel good safer" option, is a small cotton throw rug under your feet.
james_s & CDS_Torsten Also have pointed out the chair, most modern office chairs use synthetic materials, quick solution is cover the seat and back with cotten cloth. I have some all clothe restaurant napkin over the seat and I seem to use the back for hanging a cotton shirt and my hoodie.
And geggi1 is correct, today all carpets are or at least have synthetic materials
May process would be in sequence.
1.) All cotton chair, cotton clothes, cotton rug,
2.) humidifier/evaporator tray of water,
3.)rug or metal plate/rubber shoes,
4.) negative ion-generator.
The ion generator may be a "go ahead and do anyway", keeps the air clean and nice. just put in middle or room or near the opposite room
Hope all this helps, I cannot think of anything beyond what has already been suggested
Let us know how you solved it!
