HAELO is safe for daily use as each frequency set was curated and designed for daily use. However, it is important that your body receives the desired frequency sets and you allow them to assimilate and integrate to this level of optimization. Remember, no two users are alike. Therefore, we always suggest that our users tune into their own innate body wisdom to determine when enough is enough. For those who are more energetically sensitive, we recommend taking rest days as needed. Similar to any workout routine, it is the responsibility of the user to determine when rest days are required!
