What you might not have known about the brain
The brain is the body's control center and one of our most fascinating organs. It weighs only about 3 pounds, but is responsible for everything from breathing and movement to memories, emotions and creativity. Here are some surprising facts about the brain - and how you can give it the best possible support throughout your life.
1. The brain is always “on” – even when you sleep
Even when you sleep, your brain is actively working to process the day's impressions, clear away waste products, and consolidate memories. Sleep is therefore essential for both learning and mental clarity.
2. The brain consists of around 86 billion nerve cells
These cells communicate via thousands of connections – synapses – that make it possible to think, feel and act. Many of these connections can be strengthened or weakened throughout life – depending on how we use our brain.
3. The brain loves movement
Physical activity increases blood flow and stimulates growth factors that promote the formation of new nerve cells. This is especially important in the hippocampus – the area central to memory and learning.
4. You can build "cognitive reserve" throughout your life
The more you challenge your brain, the better it will withstand the natural changes that come with age. Education, mental tasks, social contact, and new experiences strengthen your brain's capacity and flexibility.
5. Nutrients play an important role
Did you know that the brain is made up of almost 60% fat – and that the omega-3 fatty acid DHA is an important building block of brain cells? In addition, choline, B vitamins, vitamin D and antioxidants are known to support normal brain function and protect against oxidative stress.*
6. The brain is affected by how you live
Stress, sleep, diet and social connections affect brain health more than we might think. So a healthy lifestyle is not only good for the body – it's equally important for the mind.
7. The brain can be shaped - throughout life
Previously, it was believed that the brain was “finished” developing after childhood. Today, we know that the brain has the ability to form new connections and adapt – even in adulthood. This is called neuroplasticity, and it means that it is never too late to learn something new.
8. The brain needs rest – and nourishment
Mental overload without breaks can reduce concentration and memory. Regular sleep, a balanced diet and daily exercise help support brain capacity and recovery.
Summary: Take care of your brain
Give it enough sleep
Exercise regularly
Eat nutritiously
Challenge yourself mentally
Be social and engaged
The more we learn about the brain, the clearer it becomes that we can influence how it works – and thrive. Take care of your brain, and it will take care of you.
* DHA contributes to the maintenance of normal brain function. The beneficial effect is achieved with a daily intake of 250 mg.
