When you feel wired and exhausted at the same time, your body isn’t being dramatic — it’s responding to depletion. In chronic stress physiology, every spike of cortisol taps deeper into dopamine and norepinephrine. The brain tries to stay sharp, stay vigilant, stay “on”… but that survival mode spends through those neurotransmitters faster than you can rebuild them. That’s why focus slips. Why sleep gets fractured. Why fatigue hits harder even when your mind feels revved. This isn’t about motivat

In cold temperatures, your body shifts into survival mode, releasing norepinephrine (or noradrenaline). This hormone plays a key role in how your body reacts to cold. 💉 Here's the science: Normally, wide, dilated blood vessels are great for blood flow. But in the cold, your body does the opposite – it constricts blood vessels to preserve heat. This process is known as vasoconstriction. 🩸 Vasoconstriction results in increased blood pressure, which can be a strain on your cardiovascular system.

‘Fasting puts your body into starvation mode’ Have you heard this statement before, and it put you off trying The Fast 800 programme for yourself? Interestingly, the opposite is true: studies have revealed that some forms of fasting can actually boost the metabolism due to an increase in blood levels of norepinephrine as a result of a decrease in serum glucose, which stimulates your metabolism and breaks down body fat cells. Now that you know the truth, you may feel motivated to give The Fast 80

✨ To rewire the brain and build neuroplasticity, 3 key neurotransmitters need to fire: ⚡ Norepinephrine (adrenaline) – get the heart rate up 🏃‍♂️❤️ to prime the brain and make all neurons fire faster. 🎯 Acetylcholine – helps us focus activity into the exact brain region we want to strengthen (frontal lobe 🧠, visual system 👀, auditory system 🎧 etc). 🏆 Dopamine – the reward chemical! A “great job, buddy” moment 👏 locks in the change and reinforces learning. So the sequence looks like: 1️⃣ S

The cold plunge is more than just a trend, it’s a full-body reset. Cold exposure activates your nervous system, boosts circulation, reduces inflammation, and releases powerful mood-boosting chemicals like dopamine and norepinephrine. It’s one of the fastest ways to build resilience and calm your mind. #coldplunge #coldtherapy #mentalwellness #nervoussystemhealth #inflammationrelief #recoverytherapy #stressrecovery #unchainedwellness #unchainedpsychiatry | Unchained Wellness Clinic
