Sleep – a precious asset that offers us rest and relaxation. In a time when the world is flooded with information, healthy sleep is becoming increasingly important. Celebrities praise their healthy sleep habits, studies highlight the benefits of balanced sleep, and the market is flooded with products that are supposed to support sleep. Gorilla Gesund has also dedicated itself to this important topic, especially when it comes to products for a healthy lifestyle, which includes our own brand of pillows and mattresses.
The influence of sleep on our biological processes
Our body undergoes many biological processes during sleep that are crucial for our health. Foremost is the brain, which stores new information and eliminates harmful waste products during sleep. Nerve cells communicate and reorganize to support healthy brain function. The body, in turn, focuses on repairing cells, restoring energy, and releasing molecules such as proteins and hormones, including growth hormones. These hormones are important not only for the growth and development of children but also for the repair of muscles, bones, and tissues in people of all ages.
The science behind the sleep needs of different age groups
The German Society for Sleep Research recommends different amounts of sleep per day depending on the age group:
- 0–3 months: 14–17 hours
- 4–12 months: 12–16 hours
- 1–2 years: 11–14 hours
- 3–5 years: 10–13 hours
- 6–12 years: 9–12 hours
- 13-18 years: 8–10 hours
- 18–60 years: 7+ hours
- 61–64 years: 7–9 hours
- 65 years+: 7–8 hours
The dangers of too much sleep
The question of whether there is such a thing as too much sleep has led to controversial discussions in science. We are all unique, so the optimal amount of sleep varies from person to person. However, if we sleep too much, it can have negative effects on our body.
The Role of Serotonin
An important factor in assessing our sleep is the neurotransmitter serotonin, which supports the natural sleep-wake cycle. During sleep, neurons transport serotonin to specific receptors in the brain to regulate sleep and wakefulness. If we sleep too long, we disrupt this process and mistakenly signal to the body that it should be awake. This can lead to dehydration and nutrient deficiencies, which in turn can cause headaches or lethargy.
The research on night owls
A study with over 24,000 participants aged 15 to 85 has found that "long sleepers" may be associated with psychiatric disorders and a higher BMI, but not with other chronic diseases that are often linked to sleep deprivation.
Finding the right balance
While the scientific community is still debating how harmful excessive sleep can be, there is no doubt that too little sleep is detrimental to health in the long term. It is therefore advisable to adhere to the recommended amounts of sleep for the corresponding age groups and to listen to the signals of your body. Occasionally sleeping in or taking naps is normal when the body demands it. However, if persistent sleep habits cause anxiety, we recommend seeking medical help to clarify the cause.
Conclusion
Sleep is crucial for our physical and mental health. The optimal amount varies from person to person, but quality and regularity are key. Sleep is not a given – it deserves our attention and care. If you need support in establishing healthy sleep habits, numerous resources are available to assist you on your journey to better sleep.
