In today’s world, the average person checks their phone 352 times a day, triggering dopamine release with each interaction. This leads to overstimulation and dysregulation of dopamine, a neurotransmitter responsible for reward and motivation. But dopamine isn’t just affected by tech use—it’s closely tied to nutrition, hydration, and sleep, all of which are regulated by electrolytes such as sodium, magnesium, calcium, and potassium.
Electrolyte Balance and Dopamine Regulation
Electrolytes play a critical role in brain function and neurotransmission. For instance, sodium helps regulate magnesium and calcium levels in the blood, ensuring proper neuronal signalling.
Balance studies have indicated that for an individual weighing 70kg and engaging in one hour of exercise per day, approximately 4,760mg of sodium (11.9g of SALT) per day is required to maintain calcium and magnesium balance. This study underscores the importance of adequate sodium intake, as insufficient levels can lead to negative balances of these essential minerals, potentially affecting overall health.
Magnesium, in particular, plays a key role in dopamine synthesis and sleep quality, both of which help maintain cognitive balance. When magnesium levels are low, sleep quality suffers, which can prevent the brain from properly resetting dopamine levels overnight. This comes back to balance, magnesium works closely with calcium. The ideal ratio is 2:1 (calcium to magnesium). Too much magnesium can block calcium benefits, so balance is key. In Naru Revive we have the correct ratio (Calcium 350mg: Magnesium 188mg) in every sachet!

Moreover, during sleep, potassium levels are also restored, further supporting cellular and neuronal function. Sleep expert Dr. Matthew Walker has emphasised how vital sleep is in maintaining overall brain health, including dopamine regulation.
Understanding Dopamine, Hydration, and Food Consumption
The relationship between dopamine, hydration, and food consumption reveals intriguing insights into our brain's reward pathways and how they influence our behaviours and preferences. While both food and water intake can trigger dopamine release, the mechanisms and effects differ significantly, influencing our propensity for food over hydration when seeking energy.
Dopamine and Food Consumption
Consuming food, especially palatable foods high in fat and sugar, is known to stimulate dopamine release in the brain. This release occurs at two distinct times: initially, when the food is ingested, and later, when it reaches the stomach. This dual release enhances the rewarding experience of eating and can drive our desire to consume more, sometimes leading to overeating. Foods rich in L-tyrosine, an amino acid precursor to dopamine, can further boost dopamine production, enhancing mood and motivation.
Hydration and Dopamine
While hydration does influence dopamine signalling, the effect is less pronounced compared to food.
Research indicates that dopamine release can occur in response to hydration, but this is often linked to the physiological need for water rather than a hedonic reward.
The brain's response to water is primarily about maintaining homeostasis and ensuring survival, rather than providing a significant pleasure-driven dopamine boost. Remember, you are already dehydrated before you feel thirsty.
Energy and Reward Pathways
The different reward pathways for food and water suggest why we might have a stronger propensity for food, especially when seeking energy. Food consumption directly impacts dopamine levels, providing an immediate sense of reward and energy. In contrast, while hydration is critical for maintaining cognitive function and overall health, it does not trigger the same intense dopamine-driven reward, making it less likely to be sought out for an immediate energy boost.
Hydration and Cognitive Function
Dehydration is another factor that significantly impacts both brain function and dopamine regulation. Studies suggest that as little as a 1% decrease in body water content can impair attentiveness, memory, and mood.
Yet, most people in the UK consume only 53% of their recommended daily water intake. This leads to subtle dehydration, which can go unnoticed until a 2% reduction in total body water triggers the sensation of thirst.
Instead of addressing dehydration with water, many people instinctively reach for coffee or snacks, further feeding into the dopamine spikes and crashes. The resulting imbalance not only worsens mental fatigue but also makes it difficult to stay focused without constant stimulation.
Breaking the Cycle: Electrolytes, Sleep, and Hydration
To break free from this overstimulation, it’s essential to maintain proper hydration and electrolyte balance. Adequate magnesium and potassium intake can improve sleep quality, helping the brain reset dopamine levels. Proper hydration ensures cognitive functions like focus, memory, and mood regulation stay sharp throughout the day.
By adopting healthy hydration practices and ensuring balanced electrolyte intake, particularly with magnesium and potassium, you can restore your brain’s dopamine balance and improve cognitive performance. Incorporating Naru Revive, with its optimal calcium-to-magnesium ratio, can support this effort, ensuring your body has the nutrients it needs to thrive.
Conclusion
In our modern, fast-paced lifestyle, constant phone use, caffeine consumption, and poor hydration have created a dopamine rollercoaster. Breaking free from this cycle requires a holistic approach—prioritising sleep, hydration, and electrolyte balance. These small adjustments can reset your dopamine levels, sharpen cognitive performance, and enhance your overall well-being.
