5 signs you’re healthier than you think

Everyone looks to the visual signs of health, the physical manifestations we can see and measure. But what if there were markers we could spot before a rash appears, energy crashes, or the bloating sets in?

This isn't a reason to ignore physical signs of ill health. It's an invitation to pay closer attention, particularly to your metabolism, if you find that none of the feelings below resonate with you.

When the body is truly healthy, the benefits go beyond clear skin, strong energy, resilience, and good hair and nails. Health also amplifies the more positive qualities in our personality. These will vary from person to person, but what follows are some that I believe are uniquely tied to a state of genuine good health.

It's worth noting that some people hold onto these qualities even through periods of ill health. But as a general rule, when we feel good, we tend to embody them more fully. With that said, let's get into it.

1. You're genuinely curious about things

There's something quietly powerful about a person who still wants to learn. Not out of obligation or anxiety, but out of genuine interest, the kind that pulls you down a rabbit hole at 10pm because you just have to know more.

This kind of inquisitiveness is often the first green shoot to emerge when someone who has been chronically unwell begins to recover. It tends to arrive before the energy returns, before the physical symptoms resolve. It shows up as a rekindled interest in something, anything, and it signals that the brain is receiving enough fuel to look outward again rather than spending all its resources just keeping the lights on.

When the body is in a state of metabolic stress or chronic inflammation, the brain shifts into a conservation mode. Survival takes precedence over curiosity. The world narrows. Things that once fascinated you feel flat. This isn't laziness or apathy, its biology. The brain is simply not in a position to explore when it is busy managing internal fires.

So if you notice yourself genuinely interested in learning, in ideas, in how things work or how to get good at a sport or skill, that is your nervous system telling you it has capacity to spare. And capacity to spare is another way of saying: things are going well.

2. You can actually switch off

There is a version of calm that most people have forgotten they're supposed to feel. Not the exhausted collapse at the end of a long day, but a genuine, settled quiet, a state where the mind isn't running lists in the background, the body isn't inflamed, and peace doesn't feel like something you have to force.

That state is physiological. It is produced, not performed.

The primary driver is GABA, the brain's main inhibitory neurotransmitter. When GABA is functioning well, neural firing slows appropriately, thoughts become less reactive, muscles release, and sleep deepens. When it's depleted or disrupted, the result is a nervous system that simply cannot find its off switch, regardless of how safe or relaxing the environment actually is.

What most people don't realise is that GABA production is closely tied to gut health. Specific beneficial bacteria, particularly Lactobacillus and Bifidobacterium strains, help produce GABA from glutamate. When the microbiome is disrupted, by poor diet, stress, antibiotics, or dysbiosis, these strains decline and inflammatory signalling rises. The gut also governs how well the body absorbs magnesium, B6, zinc, and taurine, all of which are essential for calm nervous system function. Without enough nutrients such as magnesium, the body will always struggle to be in a state of calm.

Building on the metabolic foundation discussed in the previous points, bliss is what happens when energy and nutrient intake is sufficient and inflammation is low enough that the system no longer needs to stay on guard. If you genuinely struggle to feel calm even in relaxing environments, the gut is the most logical place to begin.

3. You still know how to play

Of all the things health quietly steals from us, playfulness tends to go first and return last. Think about children, effortlessly silly, endlessly creative, completely unbothered by looking ridiculous. That quality doesn't vanish because of age. It fades because of metabolic decline.

Playfulness is, at its core, a surplus state. It requires energy, safety, and a nervous system that is not chronically braced for impact. When the thyroid is functioning well and metabolism is running efficiently, the body operates with a kind of ease that makes lightness possible. You can afford to not take things so seriously. You can engage with the world as if it were a game, because on a cellular level, the body feels resourced enough to do so.

Much like inquisitiveness in the previous point, playfulness signals that the brain has moved beyond mere survival processing. But where curiosity is directed outward into ideas, playfulness is directed into experience. It shows up in how you interact with people, with problems, with your own day. Sports, hobbies, creative work, anything that carries an element of joy and spontaneity, all of these serve not just the muscles but the mind.

If that spark has gone quiet in your life, it's worth asking not why you've lost your sense of humour, but why your metabolism may not be supporting it.

4. You expect things to work out

Optimism gets dismissed as a personality type, something you either have or you don't. But chronically pessimistic people are not broken in spirit. More often, they are running on a depleted system.

When thyroid function is strong and mitochondria are producing energy efficiently, the brain receives a consistent signal that resources are available. And the brain interprets reliable energy as safety. From safety, the mind naturally orients toward possibility. Goals feel achievable. Setbacks feel temporary. The future looks like something worth moving toward.

Flip that and you get the opposite. Sluggish thyroid output slows glucose metabolism, reduces dopamine sensitivity, and dims the cognitive clarity that makes future-thinking feel worthwhile. People in low-thyroid states commonly describe a heaviness that has nothing to do with mood and everything to do with the body's ability to generate and sustain energy.

As with playfulness and calm from the previous points, optimism reflects a nervous system that is not in survival mode. It also depends on the same network of supporting factors, low inflammation, strong B-vitamin status, adequate iron for oxygen delivery, and liver function capable of clearing the metabolic waste that dulls the mind. When those systems are working, optimism isn't something you have to manufacture. It simply shows up.

5. Ideas come easily

Creativity is often treated as a talent, something distributed unevenly at birth. But sit with a person who has genuinely recovered their health after years of struggling, and one of the first things they often describe is that their mind feels different, faster, clearer, more connected, more alive with ideas.

That's not coincidence. It's metabolism.

The brain is the body's most energy-hungry organ. When glucose delivery is stable, liver glycogen is full, and mitochondria are firing well, neurons communicate in coordinated, efficient patterns. Add in good gut health and that combination is what we experience as clarity. Creativity is what happens when there is energy left over after the basics are handled, when the brain is not borrowing from stress hormones to keep the lights on, but instead has true surplus to play with.

The thyroid, as noted across the previous points, sits at the centre of this. It governs oxygen consumption in brain cells, regulates processing speed, and influences how fluidly ideas connect. When it's underperforming, thinking becomes effortful, recall slows, and the creative range narrows. When it's well-supported, the mind moves differently, ideas arrive rather than being forced out.

Sleep ties everything together here. Deep, restorative sleep clears metabolic waste from the brain, consolidates memory, and restores the dopamine sensitivity that makes creative thinking feel rewarding. Without it, cognition becomes fragmented and reactive, responsive rather than generative.

When metabolism is strong, gut health is good, inflammation is low, and sleep is deep, the brain doesn't have to work to be creative. It simply is.

The thread running through all five

Curiosity. Playfulness. Calm. Optimism. Creativity. These are not personality traits that some people are lucky enough to possess. They are outputs of a body that is functioning well, a metabolism that is efficient, a gut that is balanced, a nervous system that is not perpetually in defence mode.

The encouraging part is that these states are recoverable. Most people who have lost them have not lost them permanently, they have simply lost the physiological conditions that make them natural. Restore those conditions, and the qualities tend to return on their own, often before any visible physical changes appear. Your mind is not separate from your body. It is downstream of it.

So the next time you feel that flicker of genuine curiosity, or catch yourself being silly, or notice that rare moment where everything just feels still, don't dismiss it as a good day. Recognise it for what it is...a sign that something in your biology is working exactly as it should.

That's worth protecting.
