The wrong sound frequencies can disrupt sleep and lead to insomnia, but the right frequencies help the body relax and prepare for a night of sustained deep sleep. Adults who put on ambient noise or relaxing music before bed fall asleep faster and wake up more well-rested than those who don’t. This is because white noise at a constant volume blocks out sudden or harsh sounds that can jolt the brain awake. The albums in Sleep Atmospheres are cool, calming soundscapes designed to do just that. So put away the NyQuil and Benadryl, this is an all-natural, non-habit forming sonic sleep-aid.
