Practice deep belly breathing to calm your nervous system and reduce stress. Try inhaling slowly through the nose, filling the lungs, holding for a few seconds, and then exhaling fully. Breathe in for 4 counts, hold for 7.
"The time to relax is when you don't have time for it."
Dim the lights, use an essential oil diffuser with calming scents like lavender or chamomile, and play soft music before bedtime to ease into a relaxed state.
