We always sleep better and deeper on rainy days. Why is that so? According to research from the University of Melbourne, there are 3 main reasons why we sleep better on rainy days :
- Increase the concentration of negative ions in the air :
The concentration of negative ions in the air increases due to the phenomenon of thunder and the friction between raindrops and the air. Negative ion particles when absorbed into the blood will create chemical reactions that reduce feelings of stress and anxiety. The increase of these particles also significantly improves the human nervous system, cardiovascular system, blood, and respiratory system. You will feel more comfortable. Furthermore, negative ions have a calming and hypnotic effect - a factor that makes it easier to fall asleep.
- The sound of the rain has a melody like a lullaby :
The sound of rain is gentle and soothing, like a wonderful lullaby that can help people fall asleep quickly. Studies have found that when listening to the sound of rain, the brain unconsciously relaxes and produces alpha waves, very similar to the state of the brain when people fall asleep.
Rain sounds are usually between 0 and 20 kHz. This sound is not annoying at all. On the contrary, it helps you feel comfortable.
- Increase levels of the hormone melatonin :
The human brain can secrete a sleep-related hormone - melatonin when in a dark or dimly lit environment. On rainy days, dark clouds obscure the light, and space becomes murkier. At this time, the amount of melatonin secreted by the brain increases, making you sleepy.
