If you are living in the Northern Hemisphere, winter has most likely arrived or is just lurking around the corner. The colder it gets outside, the more one tends to think about being warm. Going to the Sauna is a great idea at this time of the year. Actually going to the Sauna is good for us all year round, but in the summer time we tend to do more activities that makes us sweat, and as we do less of this in the winter - going to the Sauna can help us out.
When we are working out we are in action mode and our sympathetic nervous system, the "fight or flight" system, is responsible for keeping us ready for anything. Sweating in this state is good for us as it cools down the body, and it will also help detoxify our bodies.
When we are relaxed and sitting still, it is the parasympathetic nervous system , aka the "rest and digest" system, that keeps us calm and relaxed. Sweating in this state is very different for our body than when we are in action or under stress, and it can help reset our nervous system.
Being able to positively influence our nervous system is something that is very beneficial to us. Typically we spend way too much of our time in the "fight and flight" mode, from stress, sugary foods and stimulants such as caffeine. The Adrenal Glands have many different functions, with one of them being the production of "adrenaline and noradrenaline, which function to produce a rapid response throughout the body in stress situations". When we are in this "fight and flight" mode for long periods of time it starts to wear out the Adrenal Glands, and other systems get over burdened as well. We commonly know this as being "burned out".
Sweating in the Sauna while relaxing can help reset the nervous system, and give our bodies and especially the Adrenal glands a much needed break. And, we also get the beneficial detox happening at the same time. What's not to like?
Make sure that you are properly hydrated before going to the Sauna, as well as during. You will put an enormous burden on your body if you start out slightly dehydrated, and it will likely do you more damage than good. If you haven't been for a while, remember to start out gently, and slowly increase your efforts to give the body time to adapt.
Enjoy the Sauna and a nervous system reset! 😉
