Blue light at night: the hidden enemy of your sleep and well-being
We live in a world where artificial light surrounds us at all hours. From cell phone and computer screens to LED lighting in our homes, exposure to blue light has become constant. However, when night falls, this light can become a silent enemy to our health.
How blue light disrupts your circadian rhythm
Our bodies follow an internal biological clock, known as the circadian rhythm, which regulates sleep, hormone production, and many other essential functions. Blue light at night tricks our brain into thinking it is still daytime, which suppresses the production of melatonin, the key hormone for rest. As a result, falling asleep becomes more difficult and the quality of rest decreases, affecting our energy, concentration, and even our mood.
Consequences of nighttime exposure to blue light
Poor sleep not only causes fatigue the next day, but can also lead to long-term problems. Studies have linked circadian rhythm disruption to an increased risk of metabolic diseases, depression, and a weakened immune system. In addition, constant exposure to blue light at night can affect the production of other hormones essential for the body's balance.
How to protect yourself: blocking glasses and warm lights
To minimize the negative effects of blue light at night, one of the most effective solutions is to wear glasses with orange or red lenses that block blue and green light. These glasses help keep melatonin production stable, promoting deep, restful sleep.
Another key strategy is to modify your home lighting. Replacing cool white lights with warm-toned bulbs, such as orange or red, helps create an atmosphere conducive to rest. In addition, reducing screen time at least one hour before bedtime and activating night light filters on electronic devices can also help if you don't have the right glasses.
Taking care of our circadian rhythm is essential for our health. Implementing these simple solutions can significantly improve sleep quality and overall well-being, allowing us to rest better and wake up with more energy every day.
