Sleep is controlled by the brain and affects the ability of the brain to function. It is fundamental for brain health primarily due to the following factors:
- Circadian Rhythm – internal program of our body to enable sleep is linked to hormone release and the health of the microbiome – which is involved in the production of the hormones and neurotransmitters. Disruption of this cycle causes breakdown of these processes.
- Glymphatic system – newly discovered cleaning system specific to the brain that is responsible for removing metabolic waste that accumulated while awake. During sleep, the brain is rejuvenated and memories consolidated, making it ready for the next day.
- Lack of sleep triggers the body’s stress response and leads to a damaging cascade of events:
- Disruption in gut bacteria balance
- Increased blood sugar
- Increased inflammation
- Decreased immunity
- Disease processes and poor Brain Function
