Biological clock and sleep quality: How chronobiology influences sleep

Our biological clock, regulated by the natural rhythms of light and darkness, has a profound impact on our sleep quality and general well-being. Chronobiology, the study of these rhythms, helps us better understand how we can optimise our daily habits to improve our rest and, consequently, our health.

Each person has their own chronotype, a natural predisposition to feel more active at certain times of the day. Some of us are 'morning people', energetic in the morning, while others are 'serotonous', more productive in the evening. Recognising and respecting one's chronotype can make the difference between a productive day and one full of tiredness.

Light plays a crucial role in keeping our biological clock in sync. Natural light in the morning is particularly effective in regulating circadian rhythms, reducing the production of melatonin, the sleep-inducing hormone, and helping us to The exposure to artificial light, particularly the blue light emitted by computer screens and smartphones, can interfere with the release of melatonin when used in the evening hours. Reducing the use of electronic devices before bedtime can promote faster falling asleep and deeper sleep.

In addition to managing light exposure, it is essential to create a comfortable sleeping environment. A good mattress, supported by a suitable bed base, can significantly improve sleep quality. A cool, dark environment, together with breathable, quality bedding materials, helps to maintain an ideal body temperature during the night, preventing overheating and night sweats.

Finally, adapting our circadian rhythms to the demands of modern life can be a challenge, but it is a crucial step in improving quality of life and productivity. Creating a routine that respects one's natural rhythms, carefully choosing when to go to bed and when to wake up, can transform our days and make us more energetic and focused.
