Following on from my last post, I want to briefly expand on why sleep isn’t just about rest.
During sleep, your brain cleans out waste that builds up throughout the day, including harmful substances like β-amyloid that have been linked to diseases like Alzheimer’s.
This is called the glymphatic system. Since some things can’t pass through the brain’s protective barrier, this system uses fluid to move medicine in and flush toxins out. It also helps bring nutrients, such as glucose, lipids, amino acids, growth factors and neuromodulators, into the brain to keep it healthy..
So skimping on sleep doesn’t just make you tired – it affects everything from your immune system to mental health. Poor sleep can directly cause:
– Higher risk of anxiety, depression, and brain fog
– Increased likelihood of weight gain and cravings
– Reduced immune function
– Worsened skin health and premature ageing
Stay tuned for some tips on improving your sleep!
