According to the BBC, the latest research by scientists at Kingston University in England showed that it is good for the body to be healthy after awakening.
Lazy people do have lazy reasons. Maybe everyone remembers when they were young, parents always urged us to get up in the morning to stack the quilts. But scientists now believe that beds that are not stacked are more health-friendly.
New research shows that messy beds may be unsightly, but can effectively limit the growth of mites and dust mites, effectively reducing the incidence of dust allergies and asthma patients. According to statistics from scientists, even a very neat person has at least 15 million mites and dust mites on each bed. These aphids, which are much smaller than 1 mm, rely on the skin that naturally sheds the human body to survive, and produce substances that cause allergies in the human body. Scientists have explained that although the locusts need to be moistened by the sputum, once the body leaves the bedding, it is damp. The water will soon disappear. If the bedding remains as it is, then the moisture and moisture in the outside air will not enter, causing all kinds of aphids to eventually die of thirst. Researcher Dr. Prytlef said: "The easiest way is to not stack quilts after waking up. So the moist gas inside the quilt will soon dry, and the external moisture can not enter, all kinds of mites can not last long. survive."
1. Features of tape measure
Gift rulers are used for advertising and promotion. They are divided into Steel tape (steel tape) and leather tape (PVC plastic fiber tape). They are usually cute and compact. Tape measures are also called measuring tools. Eighty-five percent of the world's tape measures are exported from China.
2, the characteristics of the tape measure
(1) The tape measure is too deformed and will not fail
Why didn't it fail? The spring in the tape measure is very long, and its range from completely relaxed to fully tightened is very large. The entire stroke of the tape measure includes it, and there is a margin at both ends, so the tape measure will not fail.
(2) Pull one meter long and pull two meters long, there is no difference in tension
The spring of the tape measure is very thin, and the amount of deformation when it is tightened is also small, so the reaction force is very small, and the force change is not felt when the rule is pulled.
