Some of you may already know that JP's Originals came to fruition off the back of immense sleep deprivation and the understanding that my relationship with highly caffeinated drinks was officially over. It was hard to acknowledge the link between my lack of sleep and my anxiety and stress levels.
Why Sleep is More Important Than You Think
While you sleep, your body isn't just "off." It is performing critical maintenance that cannot happen while you are awake:
- Brain Housekeeping: Research into the glymphatic system shows that during sleep, the brain physically flushes out metabolic waste and toxins (including beta-amyloid, a protein linked to Alzheimer's).
- Memory Consolidation: Sleep is when the brain processes the day’s information, turning short-term experiences into long-term memories
- Immune Defense: Your immune system releases proteins called cytokines during sleep. Lack of sleep reduces the production of these protective proteins and infection-fighting antibodies
- Hormonal Balance: Sleep regulates the hormones that control hunger (leptin and ghrelin). This is why a bad night’s sleep often leads to cravings for high-calorie "junk" food the next day.
Mental Health Impact
The relationship between sleep and mental health is "bidirectional"—meaning poor sleep causes mental health issues, and mental health issues make it harder to sleep.
- Emotional Regulation: Without sleep, the amygdala (the brain’s emotional center) becomes up to 60% more reactive, leading to heightened anxiety and irritability.
- Depression Risk: People with insomnia are estimated to be five times more likely to develop depression than those who sleep well.
What’s Keeping Britain Awake?

Summary: A Call to Rest
Sleep is the foundation upon which diet and exercise are built. Without it, the other two cannot function effectively. In 2026, the data is clear: we are a nation that values productivity but forgets that the best way to be productive is to be well-rested
