But spending 20 minutes a day outside (sans sunscreen) can rev detox and ease body aches in as little as a week. How? Cornell University scientists say UV light revs the production of serotonin and melatonin—hormones that not only boost mood and improve sleep but also speed the breakdown and release of pain-triggering inflammatory waste called cytokines.
