Sleep and your biology

Sleep is essential for everyone, but its biological purpose is still not fully understood. Sleep affects almost every type of tissue and system in the body, from the brain and heart to metabolism and immune function. It also influences mood and disease resistance.

The amount of sleep you need is unique to your biology and lifestyle. While experts generally recommend that adults get at least seven hours of sleep per night, sleep needs can vary significantly from person to person. Factors such as activity level, health status, age, and life stage all influence how much sleep you require. For example, babies, children, and teens need more sleep than adults to support their growth and development.

Sleep is regulated by the body's release of the hormone melatonin. As darkness falls in the evening, the body starts producing melatonin, making us feel sleepy. When morning arrives, and light increases, the body's melatonin levels drop, and we feel more alert. This natural cycle is accompanied by changes in body temperature, with a drop in the evening promoting sleepiness and a rise in the morning enhancing alertness.

To improve your sleep quality, it's essential to establish a healthy sleep routine. This includes getting at least 20 minutes of natural light exposure in the morning and maintaining a regular sleep schedule. Creating a relaxing bedtime routine, ensuring a comfortable bedroom environment, and limiting screen time before bed can also enhance your sleep quality.
