Let’s see what the scientists say …

 

There are three pillars to health: proper nutrition, exercise and sleep.  And while we can usually prioritize the first two, the truth is that sleep is just as important for our physical and mental health.


 Why can sleeping too much be dangerous to your health?
 So what happens to your body if you do not sleep well at night?

 Mood and mental health issues

 REM sleep - one of the four stages of the sleep cycle - helps regulate mood.  Thus, sleep deprivation can cause a negative mood, such as irritability and anxiety.

 Sleep deprivation can also lead to depression - several time-honored studies have shown that insomnia is an independent risk factor for developing depression in young adults.  The research around this connection is constantly evolving.  However, it is believed that, as noted above, sleep deprivation can lead to negative thoughts and depressive behavior.


 Reduced concentration

 UCLA scientists have found that insomnia leads to communication problems and reduced concentration.  And according to one study, a staggering 75% of people with Attention Deficit Hyperactivity Disorder (ADHD) have a chronic underlying sleep problem.

 Increased blood pressure


 If you sleep less than five hours each night, you are at increased risk for high blood pressure.  A single night without sleep can lead to higher blood pressure levels the next day.  Scientists believe this may explain why lack of sleep over time can lead to cardiovascular problems and heart disease.

 Increased risk of diabetes

 When you are not sleeping your body does not process the hormone insulin - which regulates blood sugar levels.  This insulin resistance can then lead to the development of type 2 diabetes over time.  So if you do not sleep well at night you have a higher risk of developing diabetes.

 Decreased immune system

 When the body is weak, it employs drowsiness to promote sleep and recovery from cellular stress.  In contrast, sleep deprivation weakens the immune system.  This is one of the reasons why most of us get sick when we are not getting enough rest and sleep deprivation.
