Anyone who is too warm or too cold at night sleeps more restlessly – everyone feels that immediately. But temperature is much more than a matter of comfort: it actively controls how deep and restorative our sleep is. Studies have shown for years that the body falls asleep best when it can efficiently release excess heat and the core body temperature slightly drops.

The day was stressful, the mind is racing – and on top of that, cold feet that just won’t warm up. According to a recent study from 2025, this feeling is more than just "uncomfortable": people who are particularly prone to stress-related sleep disorders have consistently colder hands and feet than less susceptible individuals.

Sleep is much more than just rest. The latest meta-analysis from Semmelweis University in Budapest, published in GeroScience (2025), clearly shows how crucial the right amount of sleep is for our life expectancy. Based on data from 79 international studies with over 2.1 million participants, the researchers found that both too little and too much sleep increase the risk of dying earlier – sometimes significantly.

Night sweats are a common symptom with various causes such as sleeping environment, lifestyle, and illnesses. Tips for prevention: cool the room, use light bedding, avoid alcohol and caffeine in the evening, and consult a doctor if night sweats are severe.

The question of whether and how late eating affects sleep quality concerns many people. While some can have a meal shortly before going to bed without any problems, others suffer from difficulty falling asleep and restless nights.

In Germany, over 75% of working people suffer from sleep problems due to the wrong pillows. An ergonomic side sleeper pillow with memory foam, OEKO-TEX certification, and individually adjusted height (8-13cm depending on body type) can reduce neck tension by up to 80%

Sleep is an essential part of our lives – we spend about one third of our time doing it. But it’s not just the total duration of sleep that determines its quality, above all it’s the adherence to natural sleep cycles. The renowned sleep coach and Third of Life partner Nick Littlehales, known for his work with top athletes like Cristiano Ronaldo, popularized the principle of sleeping in 90-minute cycles and thereby initiated a new sleep revolution.
