1. Not Getting Enough Sleep
Although diet and exercise are very important to the brain, they won't do nearly as much for it unless you're also getting a good night's sleep.
"Sleep deprivation reduces your brain's ability to repair itself," explains Dr. Venya.
When you're not sleeping enough, and you're still up and running into the wee hours of the morning, so is your brain, which means that without rest, the following day is guaranteed to be rough. Additionally, your cognitive health over time can decline.
2. Skipping Exercise
When most people think of exercising and working out, they think about how much it affects their weight and body shape. If you're having trouble finding motivation to work out, think less about how it alters your appearance or helps you lose a few pounds. Instead, think of how good it is for your brain.
"Exercise increases blood flow to the brain dramatically, which improves memory and focus," says Dr. Venya.
So, the next time you go to the gym or even take a nice, brisk walk in your neighborhood, don't only consider how it'll make your body feel, but also how it can help out your brain health.
3. Leading A High-Stress Lifestyle
There are so many reasons to be stressed nowadays, which is truly a shame, as stress is so harmful to our bodies in various ways. Something as simple as doom-scrolling on your phone for half an hour can easily contribute to a high-stress lifestyle and put the future of your brain's health and function at risk.
"Long-term stress raises cortisol levels, which can damage brain cells," notes Dr. Venya.
If you feel like your body has been a big ball of stress lately, it's a good idea to speak to a therapist and practice simple relaxation and meditation exercises, like deep breathing, any chance you get.
4. Eating An Ultra-Processed Diet
Although it can be super easy and tempting to fill your grocery store carts with processed foods and snacks, from chips to baked goods, it's a habit best avoided.
"Diets high in sugars and refined carbohydrates will greatly increase inflammation and accelerate brain aging," explains Dr. Venya.
Studies have even linked high consumption of processed foods to an increased risk of cognitive decline and diseases like dementia. Choosing whole, nutrient-rich foods instead can help protect your brain and support sharper thinking as you age.
