Good question. If the science is anything to go by, it certainly can - one study published in the journal Sleep Vigil last year found that NSDR not only lowers stress levels, but boosts mood and cognitive performance, too.
"One of the key physiological changes is a decrease in your "fight or flight response" - it reduces the activity in your sympathetic nervous system," explains psychologist Dr Varsani. "At the same time, there is an increase in activity in the parasympathetic nervous system - the part of the nervous system that helps you rest and reset."
While what works for you might not work for the next person, NSDR involves carving out time to enter a state of deep relaxation for ten to twenty minutes a day. The more you practice, the more rewards you'll reap.
