If sleep doesn’t come easily to you, you’re not alone. Almost 30% of US adults sleep for less than six hours daily, falling short of the recommended seven to eight hours. You may struggle to fall asleep, wake several times each night or wake early and find yourself unable to drop off again. Whatever the presentation of your insomnia, it can cause poor concentration and irritability, which make it difficult for you to function during the day. Falling asleep behind the wheel or struggling with daily tasks are hazardous, but you are also more prone to develop depression, diabetes, obesity or raised blood pressure if you don’t get enough sleep. Therefore, addressing sleep problems is essential, but you first need to understand the cause of your sleeping difficulties.
