    Since my wife was diagnosed with epilepsy the ring changed her life because oura ring notifies her about her stress levels and sends her a notification on the phone letting her know that she needs to calm down and that's helpful for me because I can't stay with her the whole time due to my work but now with the ring we are able to control a little bit more her symptoms
