The Role of Consistency in Sleep

I know some people who take a very cold bath and then they take a hot shower just to warm up so they're not freezing anymore. And what that cold bath does is it actually activates your sympathetic nervous system. So within 30 minutes, once they've warmed up a little bit, they feel so much more able to get a good night's rest. For me, that doesn't work. It's so stressful to me that it takes me too long to relax after that. But a warm bath is perfect because that's helping the parasympathetic system do what it does. If you are consistent, I'm assuming it also talks to your subconscious about, oh, it's a bath
