Melatonin, like all natural dietary supplements, is unregulated and untested for long-term use in humans. Some people find that melatonin causes grogginess and depression. Others report falling asleep quickly with melatonin only to awaken in the middle of the night. Still, studies show that melatonin appears to be safe with short-term use (three months or less).
Sleep is an important part of your daily routine—you spend about one-third of your time doing it. Quality sleep – and getting enough of it at the right times -- is as essential to survival as food and water. Without sleep you can’t form or maintain the pathways in your brain that let you learn and create new memories, and it’s harder to concentrate and respond quickly.
Aging also plays a role in sleep and sleep hygiene. After the age of 40 our sleep patterns change, and we have many more nocturnal awakenings than in our younger years. These awakenings not only directly affect the quality of our sleep, but they also interact with any other condition that may cause arousals or awakenings, like the withdrawal syndrome that occurs after drinking alcohol close to bedtime. The more awakenings we have at night, the more likely we will awaken feeling unrefreshed and unrestored.
Everyone needs sleep, but its biological purpose remains a mystery. Sleep affects almost every type of tissue and system in the body – from the brain, heart, and lungs to metabolism, immune function, mood, and disease resistance. Research shows that a chronic lack of sleep, or getting poor quality sleep, increases the risk of disorders including high blood pressure, cardiovascular disease, diabetes, depression, and obesity.

You’ve got an early day tomorrow, and you know you should be asleep — but instead you’re just lying there, wide awake, watching the minutes tick by on the clock.

Below we discuss simple changes to your lifestyle and your sleep environment that can help you fall asleep faster and get a more restful night’s sleep.
