If you’re having trouble sleeping, you’re in good company. According to the National Commission on Sleep Disorders Research, at least 40 million Americans suffer from chronic, long-term sleep disorders and another 20 to 30 million experience occasional sleep problems.

Unfortunately, even minimal sleep loss can take a toll on your mood, energy, efficiency, and ability to handle stress. Ignoring sleep problems and disorders can lead to poor health, weight gain, accidents, impaired job performance, and relationship strain. If you want to feel your best, stay healthy, and perform up to your potential, sleep is a necessity, not a luxury.

It’s not normal to feel sleepy during the day, to have problems getting to sleep at night, or to wake up feeling exhausted. But even if you’ve struggled with sleep problems for so long that it seems normal, you can still learn to sleep better. You can start by tracking your symptoms and sleep patterns, and then making healthy changes to your daytime habits and bedtime routine. If self-help doesn’t do the trick, you can turn to sleep specialists who are trained in sleep medicine. Together, you can identify the underlying causes of your sleeping problem and find ways to improve your sleep and quality of life.
