Establishing a peaceful bedtime routine is essential at any age starting at infancy. After my son completes homework and after school sports, we have dinner together each night. I prefer that he gets a full night sleep so that he is ready for school and feels refreshed to tackle all of his responsibilities for the next day.
We read together in the evenings and talk about the content in the books before easing him into sleep. Sometimes, we meditate, say our prayers, and talk about the things that we are grateful for so that we recognize the blessings in our life. It keeps us centered and challenges that we face into perspective.
I have noticed that with the advent of electronics, people are spending too much time and yes, that includes me. Often many people are on their devices until bedtime and I think that it is important to ease away from them for an hour prior to sleep. As adults, it is nice to take an evening bath with Epson salts, listen to music, take magnesium or de-stress tea like Kava to also help relax into sleep.
