What’s the difference between healthspan and lifespan?

When we talk about living longer, it's important to understand the terms 'lifespan' and 'healthspan'. But what's the difference, and why does it matter? Simply put, lifespan is how many years you live, while healthspan is about how many of those years you live in good health, free from significant illnesses.¹

What your healthspan is and why it matters now more than ever

From Oscar Wilde to Doctor Who, we’re always fascinated by living longer. But a critical question remains: how can we make sure those added years are healthy ones?

How can I extend my healthspan?

We’ve become pretty good at living longer. Thanks to modern medicine, safer environments, and better access to food and clean water, average life expectancy has soared over the past century. But while we’re gaining years, we’re not necessarily gaining healthy years.

What causes menopause?

At some point, every woman experiences it. Yet despite its inevitability, menopause remains poorly understood, even by those living through it. Too often, it’s reduced to hot flushes, sleepless nights, or a punchline about midlife. But menopause is a biological shift rooted in complex hormonal changes that affect nearly every organ system in the body.

How is menopause diagnosed?

For many women, signs like hot flushes, irregular periods, mood swings, or brain fog start to appear in their 40s, but menopause doesn’t follow a strict timeline. Some experience symptoms earlier, others later, and not everyone has the same signs. So how do you know when it’s actually menopause? Is it something a blood test can confirm? Or can your GP tell just from your symptoms?

Understanding emotional eating

It’s 9 p.m. You’ve had a long day. You’re not hungry, but suddenly you’re craving an abundance of snacks. Sound familiar? You’re not alone. Emotional eating, which is the act of turning to food for comfort, stress relief, or even boredom, is a coping mechanism many of us fall back on.1 But while it may offer short-term relief, it rarely solves the problem at hand. In fact, it often leaves us feeling worse.
