Happy endorphins, happy muscles, happy skin.
You know that slipping into the hot tub feels great, but it’s not just the soothing effect of warm moving water. There’s also a biochemical reason: when your heartrate amps up and you begin to sweat, endorphins are released. Those hormones send out little neural jolts of joy—creating positive feelings, boosting your energy levels, and improving your mood.
And while your muscles don’t get the benefits of physical exercise in a hot tub, sweating does aid in their recovery from a workout—improving circulation and flushing out the lactic acid, which can keep them from complaining too loudly.
