A variety of foods help sleep.
Milk: milk contains two kinds of hypnotic substances: one is tryptophan, can promote brain cells to secrete a sleepy neurotransmitter - serotonin; the other is the regulation of physiological function of the peptide In class, people feel comfortable in the whole body and help to integrate fatigue into fatigue. For those who are debilitated by physical weakness, the hypnotic effect of milk is even more pronounced. Drinking 1 cup of milk before going to bed can stifle sleep, which is especially suitable for middle-aged and old people.
Millet: Millet is rich in tryptophan, and contains a lot of starch, easy to give people a sense of food and clothing after eating, can promote the secretion of insulin, increase the amount of tryptophan into the brain.
Walnut: It is a good nutritious food that has been proven to improve sleep quality. Therefore, it is often used to treat neurasthenia, insomnia, forgetfulness, and more dreams. The specific way of eating is to mix with black sesame seeds, make it into a paste, and take 15 grams before going to bed. The effect is obvious.
Sunflower seeds: sunflower seeds contain a variety of amino acids and vitamins, can regulate metabolism, improve brain cell suppression function, play a role in calming the nerves. After dinner, picking up some sunflower seeds can also promote the secretion of digestive juice, which is beneficial to digestion and stagnation and helps sleep.
Industrial Laser Distance Sensor
Industrial Laser Distance Sensor, we also call it secondary development laser distance module, which support TTL level and CMOS. The laser range sensor can be widely used in professional surveying, mapping, construction, robots, hunting arrows, industrial monitoring and automated measurement applications in electricity, transportation, etc. Our laser distance module supports data communication with RS232, USB with a simple adapter. The results of laser distance sensor can be evaluated with Arduino. We are always looking ahead, hoping we can make every measurement simple in life!
