Bit of an unusual topic but I wanted to share this.
Your mileage may vary but for me for years I struggled with sweaty feet and the groin area.
This had knock-on effects. It worsened social situations because I felt less comfortable and more nervous, and the sweatiness made it harder to relax.
I found out the synthetic materials like polyester and elastane don't absorb moisture well so any sweat you have throughout the day on tight-fitting garments that sit the closest to your body will trap a lot of moisture on them, but instead of absorbing it will just keep sloshing it back and forth between your skin and the fabric, which makes you sweatier.
The stuff like polyester also harms our rivers and seas and wildlife because of microplastics being released when you wash the clothes in your washing machine and that water then gets drained somewhere outside.
