Taking care of your brain shouldn’t be the responsibility of scientists and doctors alone. Every day, often without us even realizing it, we form habits that either strengthen our cognitive health or gradually deteriorate it. Experts are now warning of four major, silent threats that affect millions of people – often without their knowledge – and that most of us are exposed to on a daily basis.

A recently published book sheds light on these seemingly innocent habits that can accelerate cognitive aging, reduce concentration, and increase the risk of diseases like Alzheimer’s. Fortunately, it also presents concrete solutions that counteract the harmful effects and strengthen the brain here and now.

1. Sedentary lifestyle – a silent neuronal disorder

Sitting for long periods of time reduces oxygen to the brain and impairs communication between nerve cells. Inactivity also reduces the production of chemicals important for memory and contributes to inflammation. Even short breaks – walking, stretching or standing up – can activate the brain’s repair mechanisms.

2. Sugar and refined carbohydrates – an insidious threat

These foods are so common in our everyday lives that we often forget how harmful they can be. Frequent blood sugar spikes disrupt hormones, cloud thinking, impair memory, and accelerate brain aging. Reducing sugar intake and choosing more nutritious foods is a simple but effective protective measure.
