I've never been a great sleeper. While I've been known to doze off at any time of day if I turn on a film, I'm often up for hours in the middle of the night. It's disappointing to hear that this won't get any better as I age. Older people tend to sleep lighter than younger people. This is not because they need less sleep, but because, as clinical neurophysiologist Elena Urrestarazu Bolumburu explains, "the 'off switch' that keeps us asleep works less effectively as time goes on".

More worrying is the fact that poor sleep is associated with a higher risk of cognitive decline and dementia in the long term. But distinguishing between normal "sleep ageing" and something more serious is difficult, even for experts. Here are some warning signs to look out for.

If one of the things keeping you up at night is the climate crisis, you might identify with the term "eco-anxiety". But a recent review exposes how much disagreement there is on the definition of this term. This lack of clarity narrows our understanding of how young people – who are thought to suffer significantly from this anxiety – actually think about the changing world around them.

Eco-anxiety (or your rising energy bills) may have you thinking about how to make your home more efficient. Building "digital twins" – virtual representations of real buildings – can help look for gaps in energy efficiency and find possible ways to cut waste.

And France's recent local elections revealed the resilience of the mainstream centre left and centre right, as the far-right Rassemblement National and far-left La France Insoumise failed to take any large cities. These parties are now looking at a tricky path ahead of the presidential elections in 2027.

Is lighter sleep a normal part of ageing – or a sign of something more serious?

Sleep changes are a normal sign of ageing, but they can sometimes be an early symptom of neurodegenerative disease.

Eco-anxiety: how do young people relate to the climate crisis?

New research questions the "eco-anxiety" label and whether it really encompasses the complexity of the emotional, mental or physical distress young people feel over the planet's woes.
