Wake yourself up at night. Take an ice cold shower. Sitting at an empty breakfast table. Those apparent horrors would have a positive effect on your immune system, according to proponents of intermittent living. Is that right?
Factcheck
With intermittent living you regularly expose your body to stress situations, for example by not drinking, taking cold showers, going to the sauna or exercising intensively. This would allow your body to better arm itself against cancer, heart problems and diabetes, for example.
