For eyelashes to grow, the function of hair matrix cells in the hair follicles is important. Hair matrix cells receive nutrients and oxygen from the hair papilla in the hair follicle and divide. The repeated division and pushing out of the cells causes the eyelashes to grow.
However, if sleep deprivation continues, the function of hair matrix cells is likely to deteriorate. This can make it difficult for eyelashes to grow and easy for them to fall out.
To activate hair matrix cells, it is important to get enough sleep. Cell division of hair matrix cells is said to be active between 10 pm and 2 am. Getting a good night's sleep during this time period leads to the growth of beautiful eyelashes.
Growth hormone, which is secreted by the pituitary gland during sleep, activates hair matrix cells and repairs hairs. Growth hormone also stimulates the synthesis of protein, the main component of eyelashes. In other words, growth hormone as well as serums are essential for eyelash growth.
Growth hormone is secreted in large amounts during the three hours immediately after falling asleep. However, it is not enough to just sleep. No matter how quickly you go to bed, if your sleep remains shallow, there is a possibility that not much growth hormone will be secreted.
In other words, to get the full power of growth hormone, it is important to improve the quality of sleep. By reviewing your habits and environment, you can enhance the secretion of growth hormone when you are able to fall into a deep sleep immediately after falling asleep.
To promote eyelash growth, it is best if you can get a good sleep between 10 pm and 2 am, when the hair matrix cells are activated.
How to improve the quality of sleep? Here are 9 recommendations
1: Create the right environment in the room where you sleep.
To improve the quality of sleep, it is important to sleep in a quiet and dark room. In a bright and noisy environment, the sympathetic nervous system of the autonomic nervous system becomes dominant, making it difficult to fall asleep.
By making the bedroom dark and quiet, the parasympathetic nervous system of the autonomic nervous system will become dominant, making it easier to relax and fall asleep.
2: Choose comfortable bedding
To get a deep sleep, pay as much attention as possible to bedding selection. If the bedding is too hard or too thin and cold, the quality of sleep may suffer.
We recommend checking not only for warmth and fit, but also for firmness and moisture absorption. A cool, cool gel mat is a good choice for use during the hot summer months.
It is also important to choose a pillow size and material that will be comfortable for you to sleep on.
3: Do not eat before bed
Try to finish dinner at least 3 hours before bedtime. If you eat something right before bed, your digestive system will still be working when you go to bed, which may lead to shallow sleep.
Also, if you drink alcohol before bed, the alcohol will cause your brain to be in an active state, which may lead to shallow sleep. If you are going to drink alcohol, try to do so at least 3 hours before bed.
4:Take a bath early.
The human body is designed to lower its deep body temperature when sleeping. Taking a bath warms the body, and when the body temperature drops during sleep, it naturally causes drowsiness and makes it easier to fall asleep.
However, if you take a hot bath just before going to bed, the sympathetic nervous system is stimulated and your body becomes agitated, which may make it difficult to fall asleep.
To ensure a smooth and deep sleep, take a bath one to two hours before going to bed. Also, if the temperature of the water is 38-40°C, the parasympathetic nervous system will be dominant and the quality of sleep will be better.
5: Avoid using smartphones and computers before going to bed.
For better sleep quality, you should refrain from using your smartphone or computer before going to bed.
The blue light emitted from smartphones and computer screens activates the sympathetic nervous system of the autonomic nervous system, which can lead to poor sleep. Also, if you enjoy videos or games on your smartphone before going to bed, you may be tempted to stay up late.
It is recommended to relax by reading or listening to music instead of using your phone or computer before going to bed.
6: Get some sunshine in the morning
In the morning, open your curtains or take a walk outside to get plenty of sunlight. Exposure to sunlight in the morning and during the day creates serotonin, the happy hormone.
Then, about 16 hours after waking up, serotonin is used as a material to produce the sleep hormone (melatonin). The higher the amount of melatonin, the better you sleep.
If you wake up early in the morning and are exposed to sunlight to produce more serotonin, you will naturally feel sleepy at night, leading to better sleep.
7: Consume amino acids
If you want to improve the quality of sleep for eyelash growth, actively consume arginine and ornithine, a type of amino acid. Consumption of arginine and ornithine is expected to stimulate the secretion of growth hormones.
Foods rich in arginine include gelatin, yuba (bean curd), and bonito flakes. Ornithine is found in shijimi clams and cheese.
Also eat milk, chicken, eggs, and beans, which contain tryptophan, a type of amino acid, to produce melatonin.
8: Exercise & stretch moderately
Moderate exercise such as walking or jogging during the day will relieve muscle tension and help you sleep deeply. This will help lower your deep body temperature when you go to bed, which will help you sleep better.
In addition, stretching and lengthening your body before going to bed will relax you and put your parasympathetic nervous system in a dominant state, improving the quality of your sleep. However, be careful not to move your body vigorously just before going to bed, as this may cause the sympathetic nervous system to become dominant and you may end up in an agitated state.
9:Relax with aroma oil
If you use aroma oils when you sleep or take a bath to calm and relax your mind, you will naturally fall into a deep sleep.
For better sleep quality, we recommend lavender, rose geranium, sweet orange or bergamot. It is important to choose a fragrance that feels comfortable to you. (*Pregnant women should refrain from using lavender aroma oil.)
If you are using it in the bedroom, put the aroma oil on a tissue or cotton ball and place it near the bed or bedding. When using aroma oil, be sure to check the dosage and precautions for proper use.
