Five Things to Know about Sleep as the Clock changes

The conductor of the organization

The biological clock is an area of ​​the brain that synchronizes over the 24-hour day defined by the alternation of day and night. This cycle lasts spontaneously between 11:30 p.m. and 12:30 p.m., depending on the individual. Without this synchronization, our sleep would shift every day to the point that no one would be woken up at the same time. To do this, several synchronizers act simultaneously, the most powerful of which is light.

The Blue light from the screen spoils the Night

Blue light excites 100 times more the photoreceptor cells of the retina (melatonin ganglion cells) involved in the regulation of this circadian rhythm. By being exposed to them through the screens of phones, tablets, computers or televisions, they generate the message of massive exposure to light and slow down the process of establishing sleep.

Stimulants don’t help with Sleep

Stimulants like coffee and energy drinks, as well as alarm clocks and lights—including those on electronic devices—interfere with the so-called circadian rhythm or biological clock. While acknowledging that sleep is especially affected by the lifestyle and health of each individual

Sleep “Cleans” the Brain

While we sleep, we stop capturing information from the outside and our neurons work to make sense of it. The brain reviews the memories formed in the last hours, analyzes them, discards those it considers irrelevant and reinforces those it believes useful. It is essential to get enough and quality sleep to fully recover and better retain what has been learned. They observed that to eliminate its wastes, the brain allows CSF to flow through its blood vessels. The liquid thus drains the proteins stuck between the cells (such as beta-amyloids- which causes Alzheimer’s disease)  but also the debris of dead cells, which it then eliminates through water channels: the aquaporins.

Sleep Repairs the Brain

American scientists found that working the night shift has an impact on the development of malignant tumors. For seven days, the researchers analyzed two groups of volunteers who worked under artificial lighting at night and in the daytime. It turned out that those who worked at night had a failure in the natural mechanism of DNA repair, and their leukocytes were more vulnerable to radioactive radiation. Sleep is a vital process, and it affects absolutely all areas of the body. Starting from mood, ending with such important things as the work of the heart and brain. One of its functions is restoration at the cellular level.
