Research shows that most people need 7-8 hours of sleep to function optimally. Getting less than the recommended hours of sleep compromises your health- it can affect memory, productivity and bodily functions such as the immune system, appetite, lungs & kidneys etc. studies have also shown that insufficient sleep is linked to weight gain. people with less time to sleep have more time to eat drink and snack. Hormones in the blood are also affected- the hormones that tell your brain that you’re hungry/full vary depending on how sleep deprived a person is. the risk of type 2 diabetes increases, as long as cancer.

Point is, sleep more, it’s good for you.
