Feeling down? Try good light

Your biological clock


With the help of light, our biological clock keeps our body in balance with the time of the day. It improves our sleep, we feel more rested, have more energy and feel better!


The biological clock, also known as the circadian rhythm, is a natural process that regulates various physiological functions in your body. It is controlled by a group of cells in the brain called the suprachiasmatic nucleus (SCN), which receives signals from the eyes about the light-dark cycle in the environment. These cells sends signals to other parts of the body to adjust the timing of different processes, such as the release of hormones and the sleep-wake cycle.



One important hormone that is controlled by the biological clock is melatonin. Melatonin is responsible for making us feel sleepy and is released in the evening when it is dark. On the other hand, cortisol is a hormone that makes us feel alert, and it is released in the morning when it is light. This helps us to be awake during the day and sleep at night.

The biological clock also controls digestion, metabolism, body temperature, and immune system function. It helps to coordinate these processes so that they occur at the most appropriate times for the body. For example, digestion is most efficient during the day when we are awake, and metabolism is highest in the morning when we need energy to start the day.


Overall, the biological clock plays a crucial role in maintaining the body's overall balance and well-being. It helps to coordinate different processes and ensures that they occur at the most appropriate times for the body. When the biological clock is disrupted, such as when we travel across time zones, work night shifts, or spend too much time inside it can cause sleep disturbances and other health problems.


So, spend at least half an hour outside every day and when inside stay within one metre of a window. If this is not possible install electric light that mimics daylight.
