During warmer months, slugging may not be necessary because there's more moisture in the air. If your skin still feels dry, try slugging with a very thin layer of petroleum jelly. Patel also suggests experimenting with a shorter time period so there's less risk of sweating. While Akram suggests just slugging once a week in summer.
