It starts like this: you’re getting things done, holding down a job, the bills are paid, the family's looked after. From the outside, everything looks fine.

But somewhere around 10pm, you slump onto the sofa and wonder why you feel so completely spent. Not just physically tired but foggy, flat, and a little disconnected from the version of yourself you used to be.

Sound familiar? Then we need to talk about sleep – but possibly not in the way you've probably heard before — "get eight hours, avoid screens, don't drink coffee after 2pm." You already know that. What you might not know is just how profoundly poor sleep is quietly dismantling your health, your hormones, and your sense of self, especially once you're past 35.

The Age Where Sleep Gets Harder — and Matters More

Here's an uncomfortable truth. According to YouGov research[i] surveying over 2,000 British adults, men and women aged 35 to 44 at 58% are among the least likely to feel well-rested when they wake up. Right at the point in life when pressure from career, family, and finances tends to peak, your sleep is likely at its worst.

Research by Numan[ii] also found that British men are sleeping an average of just 6 hours and 35 minutes per night, well below the NHS recommended minimum of 7 hours and nearly half of men surveyed said they find it difficult to fall asleep in the first place.

What Poor Sleep Is Actually Doing to Your Body

Let's start with testosterone, because this is where it gets personal.

Sleep loss and reduced sleep duration have been associated with lower morning and 24-hour testosterone levels, alongside elevated afternoon and evening cortisol, reflecting an imbalance in anabolic–catabolic hormonal regulation. Testosterone drives your energy, muscle mass, motivation, libido and mood.

Some studies show that just one week of sleeping less than five hours a night can lower testosterone by 10 to 15% — equivalent to ageing your hormonal profile by 10 to 15 years[iii]. Think about that for a moment. You could be eating well, training consistently, and still fighting an uphill battle — simply because you're not recovering properly at night.

Aviva's[iv] research found that one in five adults who reported poor sleep had gained weight as a direct consequence and it's not hard to see why. Poor sleep disrupts appetite hormones, increases cravings, and leaves you reaching for quick-fix energy from sugar and caffeine.

The Hidden Cost No One Talks About

The Sleep Charity's 2024 Sleep Manifesto[v] found that 37% of UK adults experience insomnia, and nine in ten people are experiencing problems with their sleep — yet the normalisation of poor sleep has left many people suffering in silence.

The confidence that's been quietly slipping away, the patience that feels thinner than it used to be, the sense that you're working hard but going nowhere — these aren't character flaws. They're symptoms.

So What Can You Do?

The good news is that sleep responds quickly to the right interventions. Getting your sleep right (consistently, not just occasionally) is one of the highest-return investments you can make in your health. It makes your training more effective, your nutrition work harder, and your mind sharper.

This is exactly why, at ChangingMen, sleep sits at the centre of everything I do with men over 35. Not as an afterthought. As a foundation.

If you're tired of feeling tired, and you're ready to finally address the root cause rather than push through it, let's talk.
