How not getting enough sleep affects you

Not getting enough sleep is linked to a range of illnesses and could even alter the activity of our genes which control our response to stress, immunity, inflammation and overall health. Here's why you need a good night, every night.

More than 70 percent of adults get less than eight hours of sleep a night on weekdays – and 40 percent get less than seven hours. Lack of sleep can have a negative impact on the immune system and can even lead to weight gain.

Are you sleep-deprived?

Take action: Check for symptoms: you wake up tired; you are more irritable than you used to be – every little thing bothers you; you forget phone numbers and other things, and you often misplace your keys; lately, you've noticed that you have trouble learning new things; you are more susceptible to colds and flu than you used to be; you have trouble concentrating; you have blurry vision; and you fall asleep while reading a book or watching television.
