The discs are good for one day once removed from the bag.
- Some people wear them just for their NuCalm session
- Some wear the disc all day for an extra bit of calm
- Some wear the disc to sleep; if you struggle with sleep, then wearing the disc to sleep may help
You can reuse the same disc if using multiple times per day (on yourself). The only rule is to use a fresh disc everyday and keep the discs stored in the faraday cage bag that they come in.
