We all understand that getting enough sleep is good for our brains and helps us think clearly. Many experts recommend around 8 hours of sleep each night, but the right amount for feeling refreshed can vary from person to person. If you’re training for a marathon and doing long-distance runs, you might need more than 8 hours to recover properly.

On the flip side, if you’re not very active, you might benefit from less than 8 hours of sleep, as long as it refreshes your brain. Other things like the supplements you take, your diet, genetics, and your body’s natural rhythm can also affect how well you sleep. It’s not just about the amount of sleep; your sleep position matters too.

While many people think it doesn’t matter whether you sleep on your stomach, back, or side, recent research suggests that sleeping on your side might be better for your brain. It could help clear away harmful substances from your brain and possibly lower the risk of diseases like Alzheimer’s. So, choosing the right sleep position is also something to consider for a healthy brain.

Clearing Brain Waste During Sleep: Unveiling the Glymphatic Pathway

When you’re asleep, your brain has a cleanup system called the glymphatic pathway, which works to get rid of harmful waste. This system becomes more active when your brain is less alert. The glymphatic system uses cerebrospinal fluid to clear waste from the central nervous system by exchanging fluids between the brain and its surroundings.

Picture this: cerebrospinal fluid enters the brain’s connective tissue, and the glymphatic system removes fluid from different parts of the brain and spinal cord. When you’re asleep, the arteries in your brain pulsate, determining how much the extracellular space in your brain expands or contracts. A bigger space during sleep allows for better waste clearance because there’s more room for fluid to flow.
