- Indoor comfort: The low humidity levels also make it easier to maintain comfortable indoor temperatures, as the air is less likely to feel muggy or oppressive.
While the low humidity can be a welcome relief from the heat, it can also lead to dry skin and lips, so it's important to stay hydrated by drinking plenty of water.
