Here is a summary of what can be affected when we are sleep deprived.

- Reproductive system in men is affected - Levels of testosterone drop when we are sleep deprived.
- Your immune system is compromised - Not only will this affect your risk of getting sick, from everyday colds and flu, being sleep deprived means you are at a potential risk of developing cancer.
- Risk of stroke and heart attack increase - Sleep helps lower our blood pressure, and when we are sleep deprived our blood pressure can increase, which increases our risk of cardiovascular disease.
- Increased risk of depression and anxiety - deep sleep helps quieten down the sympathetic nervous system which our fight, flight or freeze system. When we are sleep deprived our Amygdala our emotional centre is 60% more reactive than when we have had the recommended 7-9 hours good quality sleep per night.
