Meditation can be a great quick fix for one night (or for every night). According to the Huffington Post, a 2009 study found that meditation could even help with insomnia.
Meditation is one exercise that will help you not only during those seven hours of sleep but during your daily life as well. The key to meditation is to find relaxation. Understanding how to find relaxation within yourself can help during the day with stress and daily life, which will ultimately affect your sleep.
