7 Habits That Age You Faster (And How to Avoid Them)

Did you know that how old you feel is actually far more influenced by your daily habits rather than your genetics? Low energy, brain fog, poor recovery, stubborn weight gain and joint stiffness are all signs of accelerated ageing – all of which are usually driven by lifestyle.

The good news is that habits are largely within your control. What’s more, small and meaningful changes can have a dramatic effect on biological ageing while protecting your cells and restoring youthful energy. Even better, it doesn’t require extreme diets or invasive procedures.

Here, we explore the most common premature ageing habits, explain what’s really happening at a cellular level and show how modern longevity tools and supplements like NAD+ can support and future-proof your health.

What Does Ageing Fast Really Mean?

Your chronological age simply means how many years you’ve been alive. Your biological age reflects how well your cells, organs and systems are functioning. When biological ageing speeds up, you might notice:

This is what we call cellular ageing. One of the biggest reasons for it is the decline of NAD+ – a molecule found in every cell that is essential for energy production, DNA repair and mitochondrial function. NAD+ and ageing are deeply linked. As NAD+ drops, your cells lose their ability to repair and regenerate effectively. And, unfortunately, many modern lifestyle habits quietly speed up this decline.

7 Habits That Age You Faster (And How to Slow Ageing Naturally)

Most people don’t realise how strongly everyday behaviours influence how they’re feeling as well as their long-term vitality. Here are some of the most damaging lifestyle habits that cause ageing – and how you can reverse them.

Chronic Sleep Deprivation

Sleep is essential for your body, mainly because it allows your body to repair itself. Without it, hormone balance, immune function and cognitive performance start to deteriorate.

Lack of sleep also depletes NAD+ levels, reducing your body’s ability to regenerate cells and maintain mitochondrial health.

If you’re experiencing brain fog, poor recovery, weight gain, dull skin or fluctuating moods, you could be ageing faster. But there is a fix:

Poor Diet

The NHS highlights strong links between processed foods, inflammation and long-term disease risk. High sugar intake causes glycation, which is where sugar binds to proteins and damages collagen, blood vessels and mitochondria. This speeds up inflammation and oxidative stress, which are two major contributors to cellular ageing! Ultra-processed foods also impair mitochondrial energy production.

To combat this:

Chronic Stress

Research shows that chronic stress elevates cortisol, which suppresses the body’s immune function, damages mitochondrial function and speeds up telomere shortening – a marker of biological ageing. Stress also drains NAD+ levels faster than almost any other factor.

There is a solution, though:

Sedentary Lifestyle

Lack of movement reduces mitochondrial density and insulin sensitivity. Both of these accelerate muscle loss and metabolic ageing. Daily movement stimulates NAD+ production and mitochondrial biogenesis, which makes it one of the most powerful longevity habits you can do.

Try to achieve:

Excessive Alcohol

Alcohol is a potent depletor of NAD+ levels. It creates oxidative stress, disrupts sleep and damages liver detox pathways. Even moderate overuse can significantly impact cellular ageing.

This is why it’s important to have alcohol-free days every week and ensure you are hydrating before and after drinking. You should also try to choose lower-sugar options to further improve your physical health.

Poor Nutrient Intake

Nutrient deficiencies quietly speed up ageing by impairing mitochondrial enzymes and DNA repair. B-vitamins are particularly critical because they are directly involved in NAD+ production. Magnesium, Zinc and Vitamin D are also important, and without them you may experience fatigue, cognitive decline and weakened immunity.
Ignoring cellular health

Expensive skincare, supplements and workouts won’t fully protect you if your cellular energy systems are already declining. This is because ageing begins inside your mitochondria and NAD+ is the molecule that powers cellular repair, detoxification and regeneration.

Put simply, without supporting NAD+, the other surface-level fixes and good habits just can’t keep up.

How to Slow Ageing by Supporting NAD+ Levels

NAD+ fuels:

But we know that NAD+ levels naturally decline by up to 50% by age 50. There are ways you can support NAD+ levels, though, with:

That’s not to say that NAD+ supplements are a magic solution. Instead, they should be used alongside healthy daily habits and good intentions to complement your anti-ageing approach. With consistent actions and a proactive mindset, you will likely see good results and begin to feel better on a cellular level.
