Cold exposure — from cold showers to ice baths — has surged in popularity among health enthusiasts and biohackers. But does it really boost immunity, or is it just a trend?
Studies suggest that controlled cold exposure can stimulate immune activity, improve mood, and enhance metabolism. The key is consistency and safety.
Popular methods:
- Daily cold showers (30 seconds to 2 minutes)
- Ice baths (1–3 times per week, under supervision)
- Cryotherapy sessions (professional clinics)
Potential benefits:
- Activates brown fat and boosts metabolism
- Increases endorphin release (mood elevation)
- May increase white blood cell activity
- Improves stress resilience
Start slow and always listen to your body — cold therapy is powerful but not for everyone.
