Don’t underestimate the power of sleep
Did you know that….
- Sleep loss costs the UK economy over £30 billion a year in lost revenue
- After just one night of only four or five hours’ sleep, your natural killer cells drop by 70%. Natural killer cells are your virus and cancer fighting cells
- Brain scans reveal a 60% amplification in the reactivity of the amygdala – a key spot for triggering anger and rage – in those who were sleep-deprived
- Sperm counts were 29% lower in men who reported regular poor sleep
On The In-Sync Diet we recognize that biorhythm is one of the most important influencing factors on health. Biorhythm is our sleep wake rhythm that has an impact on every organ and system in our body from our heart function down to our digestion. And its influence on the immune system is massive. When we are out-of-sync we become fatigued, hormonally imbalanced, unable to sleep and start to store fat around the middle.
We are genetically programmed for twelve hours of activity and twelve hours of rest of which some will be sleep. When our brain senses darkness we produce a hormone called melatonin which is designed to make us feel drowsy. Melatonin is also a crucial repair hormone that works to protect us against disease.
In this article leading neuroscientist Matthew Walker talks about why sleep deprivation is increasing our risk of cancer, heart attack and Alzheimer’s and what you can do about it.
