A new study, published in the Journal of Applied Psychology, finds that a hot bath may help reduce inflammation and improve metabolism.
As a part of an experiment, each study participant took a hot bath with water temperature 102°F (39°C) for one hour. The researchers took a blood sample before the bath and 2 hours later. Also, the measured participants’ blood pressure, blood temperature, and heart rate every 15 minutes.
Having analyzed the received data, the researchers concluded that just one immersion into hot water caused a spike of interleukin, a marker of inflammation, and increased nitric oxide (NO) production. Nitric oxide, in its turn, causes blood vessels to relax lowering blood pressure and improves glucose intake into tissues. It has anti-inflammatory properties as well.
