Five facts about your brain

Brain Awareness Week

Your brain is a complex organ that controls every process that regulates your body, including thought, memory, emotion, motor skills, touch, breathing, temperature, appetite and your vision. To celebrate this important organ, we’ve put together a list of five fascinating things you might not know about the brain:

To mark this day and to celebrate this important organ, we’ve put together a list of five things you might not know about the brain:

1. It would take you over 3,000 years to count each cell in a human brain

According to Age UK, the average human brain contains about 100 billion neurons. This is about the same numbers of stars as there are in the Milky Way. Neurons are connected by trillions of synapses, and information runs between neurons in everything you do, think or see. If these signals are affected in any way, it can lead to physical symptoms such as muscle pain and you may need an Electromyography (EMG) to diagnose whether you have a nerve or muscle disorder.

2. Short term memory lasts less than two minutes

Have you heard the myth about goldfish only having a 30 second memory? The human brain too can also only retain small amounts of information, keeping this available for easy access for about 90 seconds.

3. Headaches are caused by a chemical reaction

Chemical activity in your brain, the nerves and blood vessels (as well as the muscles in your head and neck) can play a role in headaches. Changes in the levels of oestrogen and serotonin, which helps send signals between nerve cells, can trigger a headache or migraine.

4. Exercise is good for your brain

Aerobic exercise raises your heart rate and increases blood flow around your body, including to your brain. As you breathe more heavily, more oxygen is delivered to your bloodstream and to your brain where it helps produce neurons in the part of your brain that controls memory and thinking. It’s thought that this may help the effects of dementia.

Exercise also makes you feel better, can help you manage your weight (and lower your blood pressure, which reduces the risk of stroke).

5. Alcohol affects your brain

Prolonged use of alcohol can lead to slowed reaction times, blurred vision, speech problems and memory issues. According to Alcohol Change UK, there’s evidence that regular excessive drinking can even increase your risk of developing the most common forms of dementia, including Alzheimer’s Disease and vascular dementia.

It’s not too late to change your drinking habits – our guide to healthy living can help.
