Understanding food noise: Numan's new insights on how it affects us

Numan is uncovering what's really driving our cravings: food noise. Our recent survey, conducted with Attest, shows that almost nine out of ten people in the UK feel tempted to snack when they're not even hungry.

Can you work out too much? What overtraining does to men’s testosterone levels

Exercise is good for you, until it isn’t. Most of us are told to move more, train regularly, and push ourselves to get stronger and fitter. But there’s a limit. And for men who regularly train at extreme intensity and volume, consistently going beyond that limit may quietly chip away at one of their most important hormones.

When most people think about testosterone, they picture muscles, mood, and libido. What doesn’t often come to mind is bone health.

What men need to know about testosterone and heart health

Testosterone isn’t just about sex drive or gym performance. In fact, your heart might depend on it more than you think. For decades, testosterone has been misunderstood, framed as a macho hormone tied to aggression or vanity. But behind the clichés lies something far more complex. Testosterone plays a vital role in nearly every system of the body, including the cardiovascular system. And for men, especially as they age, low testosterone may signal more than fatigue or low mood.

The biology of food noise

You might be working, driving, or sitting in a meeting, but part of your brain is elsewhere, mentally rifling through the kitchen cupboards. This intrusive soundtrack of food thoughts, known these days as “food noise,” is more than just a passing craving. It’s a psychological and biological tug-of-war that scientists are only beginning to map.

Hunger vs cravings: how to tell the difference

Why food noise gets louder at night

Almost a third of us are guilty of raiding the fridge at night, after we’ve had our dinner, according to our new nationwide survey of over 2,000 UK adults. It’s only natural to fancy a snack in the evening, even if you’re not hungry.

Understanding your thyroid test results chart

If you’ve ever had a thyroid function test (TFT), you’ve probably stared at a confusing lab report filled with markers like TSH, FT4, and FT3, and wondered what on earth it all means. But know that you’re not alone. Thyroid testing is pretty common, yet many people don’t fully understand what their results are telling them.

Thyroid health and female fertility: why blood testing matters

It’s not a hormone most people think about when planning for pregnancy, but the thyroid plays a quiet, important role in fertility. Nestled in the neck, this small gland affects everything from energy levels to menstrual cycles. And when its signals are off, even slightly, it can impact a woman’s ability to conceive or carry a pregnancy to term.

The overlooked symptoms of hypothyroidism

You’re tired all the time. Your skin feels dry, your hair’s thinning, and the number on the scale seems to be moving up even though nothing’s changed. It’s easy to chalk it all up to stress, age, or leading a busy life. But these seemingly unrelated symptoms may be connected by a common thread, and it might be your thyroid.
