If you are amongst those who complain about tossing and turning through out the night, you may want to really start focusing on your sleep hygiene, reports The Guardian.

When you wake up in the morning, do you typically feel well rested and refreshed? If the answer is no, you are likely not getting enough quality sleep. The average adult requires seven to nine hours of uninterrupted sleep to function optimally every day. But the reality is that not everyone is able to routinely achieve this amount of sleep.

Perhaps you’re one of those who think with enough coffee or energy drinks in your system, you can always make it through the day despite your sleep deficit? Let me warn you that sleep deprivation is more serious than you may realize, as it is associated with heart disease, diabetes, hypertension, and even Alzheimer’s disease.
