🔥🧠 Did you know? Regular sauna sessions may help protect your brain against Alzheimer’s disease. Studies suggest that heat exposure can boost neuroprotective proteins, improve blood flow to the brain, and reduce inflammation — all key for long-term cognitive health.

The best type? Traditional Finnish saunas (dry heat at 170–200°F) have the strongest research backing. Aim for 15–20 minutes, 3–4 times per week, to tap into those brain-boosting benefits, without overdoing it.

Think of it as a workout for your cells and a spa day for your mind. 🙏

🧐 How is Zest able to detect early memory changes decades before existing tests?

Our new Precision Memory Assessment (PREMAZ) is a cutting edge new digital test capable of detecting whether you’re likely to get dementia, in just 10 minuties.

Hear from our founder about what makes our technology so powerful.

Try this exercise for your brain!🧠✨

When you practice this exercise you are activating both hemispheres of your brain through the corpus callosum. Bilateral coordination is a such an important exercise for the brain. Additionally, it also improves spatial awareness and neural processing!

Rules are as follows:
1. Warm up your fingers, and your wrists.
2. Then make a fist (thumb free) with one hand, and with the other hand point 4 fingers at the fist.
3. Then start to alternate back and forth.
4. Start by looking at your hands, as you improve try to look away! 👀
5. Try going the opposite way!

🧠 Dementia involves complex brain changes, signaling something much more serious than getting older.

Understanding leads to better prevention, management and support for those affected.

👉🏼 3 Ways to Prevent Dementia:

1. Maintain healthy blood glucose 🍫

Recent research has highlighted the central role that glucose plays in healthy brain aging. High blood glucose - both over an extended period and in the short-term spikes described above- damages small blood vessels in the brain and leads to vascular dementia [1]. Another study found that young adults who are at a high risk of developing Alzheimer’s disease due to genetic abnormalities show disrupted glucose metabolism across various brain areas [2]

2. Regular aerobic exercise 🏃‍♀️

Aerobic exercise releases BDNF, a compound that stimulates the growth of neurons, enhances focus, energy, mood and concentration, and has long-term benefits for memory and overall brain health [3]. Regular exercise significantly reduces the risk of age-related cognitive decline and helps prevent diseases such as Alzheimer’s and Parkinson’s [4].

3. Supplement with Omega-3 💊

Robust evidence shows that omega-3 supplementation can significantly enhance learning, memory, executive function, and the amount of blood flow to the brain in cognitively healthy adults, [5, 6] and a recent study of UK Biobank data found that people with higher circulating levels of omega-3 had a nearly 30% reduced risk of developing dementia. [7] An earlier meta-analysis found that just 100mg/day of dietary ALA (natural omega-3 from your diet) reduced the risk of Alzheimer’s disease by 37%. [8]

This phenomenon is related to ‘context-dependent memory,’ where being in the same sensory context during learning and recall enhances memory performance. 🧠

The act of chewing gum may also increase blood flow to the brain and improve concentration, further aiding memory retention.

Additionally, the flavor and act of chewing can serve as subtle cues that trigger retrieval pathways in the brain, linking the test environment to the information learned. 📝

While this isn’t a guaranteed method for acing exams, it highlights the fascinating ways sensory experiences can influence cognitive function. This simple habit might give you an edge when it comes to remembering key information. 🔑

📣 Big news from Zest HQ 🥳

We’re thrilled to announce that some of London’s leading clinics on historic Harley Street have adopted our Cambridge-backed cognitive assessment platform to proactively protect and optimize patients’ brain health.

The assessment PREMAZ (precision memory assessment by Zest) was developed as part of a long standing collaboration between Zest and , with the goal of detecting subtle cognitive decline years earlier than traditional testing.

🧠 As we continue to bring this test into the clinical environment we hope to help build a healthcare system where screening for dementia is as routine as screening for cancer and diabetes.

Women are twice as likely as men to develop Alzheimer’s — but here’s the empowering news: nutrition can be one of our greatest tools for protection. 🧠✨

New research shows that women who consistently prioritize brain-healthy eating patterns dramatically reduce their long-term dementia risk:

🥗 Mediterranean diet → 27% lower risk
🍇 MIND diet → 28% lower risk
🥦 Other high-quality diet scores → 23% lower risk

Meanwhile… diets high in ultra-processed foods, refined carbs, and pro-inflammatory fats were linked to a 30% increased risk of developing dementia. 😳

The takeaway?
✅ What you choose to eat every day matters.
✅ What you avoid eating matters just as much.
