People who compensated for sleep deprivation with catch-up sleep did not have an increased risk of mortality. People who consistently slept too little without ever making it up did

People with insomnia have a specific tension profile, in which sleep-related and anxiety-related forms weigh most heavily. This explains why insomnia can be so persistent

A forty percent higher risk of dementia. Brains that function as if they are four years older. These are the figures from a study involving more than 2,700 adults with chronic insomnia

When you’re under pressure your body enters a state of alertness. The stress hormone cortisol keeps you vigilant. That’s useful in urgent situations, but the brain doesn’t distinguish between a caregiving task tomorrow morning and a lion around the corner. Under stress, the body remains in a heightened state of readiness, which prevents proper recovery during sleep. As a result, you either don’t get enough sleep or the quality of your sleep declines.

During a scroll through social media, I notice how persistent certain sleep myths still are. I’ve listed four common ones.

A study by researchers from the University of Salzburg compares eight popular sleep trackers with polysomnography, the medical gold standard for sleep research. The findings are surprising.

A large observational study in the European Journal of Preventive Cardiology, conducted among over 53,000 adults, shows that three small daily adjustments together can already make a noticeable difference for your heart

Various scientific studies confirm that listening to music before going to sleep can improve sleep. This is especially true for people with mild to moderate sleep problems.

The ‘Dutch Method’: A viral sleep trend that misses the science

As long as your days are filled with obligations, your evenings will be filled with procrastination. That’s why simple solutions like putting your phone away or going to bed earlier rarely work.

The next time your “smart” watch tells you that you only got 45 minutes of deep sleep or your sleep score has dropped below 70, take a moment to breathe calmly

The analysis of a massive sleep dataset mainly shows that sleep is not a mysterious process over which you have little control. On the contrary, small and consistent behavioral changes can already make a big difference.

Light is a powerful signal for the body. It influences our biological clock, sleep, mood, and cognitive performance. But it’s not just about how bright the light is. It also matters when and what type of light we’re exposed to.

According to the American Academy of Sleep Medicine and the American Academy of Pediatrics, young people between the ages of thirteen and eighteen need eight to ten hours of sleep per night for optimal health and development. Yet the majority do not meet this standard

We tend to think that fatigue is about the number of hours we sleep. Eight hours is good. Seven is borderline. Six is a problem. But what many people don’t realize is that you can sleep a perfect eight hours and still feel exhausted. Not because you lack sleep, but because you lack regularity.

Do you always sleep with your bedroom door closed, even if you live alone? That is probably not a random habit. Many people do this almost automatically. The door closes, the light goes off, and only then does it feel like the night can begin. What is interesting is that, according to research, this small ritual says a lot about your personality

It’s the paradox of the insomniac: the harder you try to sleep, the more difficult it seems. But why does this happen? Why can’t we sleep, precisely when we want it so badly?

Lying awake is rarely a matter of not being tired; it’s often a matter of not being able to stop thinking. Rumination — endlessly chewing over thoughts — keeps your system alert when you want to switch off. One technique that tries to break this pattern is the cognitive shuffle, developed by cognitive scientist Luc Beaudoin

Many people experience a surge of alertness shortly before bedtime. Why is that?

Yoga combines movement, breathing, focus, and relaxation. This appears to reduce stress and positively influence your nervous system. Interestingly, it's not about the gentle, slow yoga, but rather more intensive forms like power yoga or vinyasa flow
