What’s the secret to keeping your brain healthy?

It’s not an easy question to answer.

But luckily neuroscientists have been studying this question intensely over the last couple decades and they’ve come up with some interesting answers.

Check out this intriguing video from neuroscientist Dr. Tara Swart on her top 5 ways to keep your brain healthy:

For those of you who can’t watch the video, here are her top tips in writing:

First of all, Swart’s top 5 brain-friendly foods are salmon, avocado, eggs, nuts and seeds, and coconut oil and olive oil.

She says that even though your brain only weighs 2-3 kilos, it sucks up 20-30% of the breakdown products of a healthy balanced diet, so glucose is a resource for the brain.

Swart’s second tip is to get an adequate amount of sleep. It takes 7-8 hours for our brain to clean itself overnight and that’s why sleep is so important.

If you have any sleep disturbance, you can be operating with an IQ loss of 5-8 points the next day.

Swart’s third tip is hydration. The general advice is to drink half a litre of water for every 15 KG of your body weight per day. For the average male, this would be approximately 3 litres of water per day.

Swart’s fourth tip is oxygen. Just doing 10 deep breaths before a high stakes meeting can really send some extra resources to your brain. Ideally you would move around all day, doing an average of 10,000 steps.

Swart’s last tip is meditation. The evidence shows that 12 minutes of meditation per day reduces your stress hormone levels allowing more of a pause button between emotional instinctive reactions and how you choose to behave and think.
