Why do we need to sleep? We are putting ourselves at risk in many ways when we compromise our sleep and we can see some of the problems below.
This is what happens if we are not getting enough sleep:
Increase risk for development of depression and anxiety and increase negative mood states like irritability and crankiness
Increased risk for high blood pressure
Increase blood level of C-reactive protein, a sign of inflammation. High levels of this protein may increase risk for atherosclerosis, or hardening of the arteries
Increased risk of diabetes: sleep is a powerful regulator of appetite and weight control
Increased risk of dementia and Alzheimer’s disease
Increased risk of car accident and work errors
increased risk of miscarriage for women who works nights and tend to lack sleep
Sleep deprivation also
