This study shows that using a sauna – even just one session – can temporarily boost your immune system. When you sit in a sauna, your body releases more white blood cells into your bloodstream. These cells are like your body’s “defense team,” helping detect and fight off infections.
Think of it like sending more security guards out on patrol. With more of these cells circulating, your body is better prepared to spot and respond to potential threats.
Interestingly, this effect is similar to what happens during moderate exercise – your body activates its natural defenses as a healthy response to the heat.
However, the study also notes that this boost is temporary and was observed after a single sauna session. More research is needed to confirm long-term immune benefits, but these findings help explain why regular sauna use has been linked to overall health and wellness.
