Whether it is a dietician or a doctor, if you want to measure your weight, you should measure only after urinating in the morning. According to experts, there are reasons and rules behind everything. Have you ever noticed that when they are admitted to air hostess or army, then why is their length measured usually in the evening? This is not a coincidence but a scientific reason. There is a slight change in our length at different times of the day. Let us understand this interesting fact.
Actually, our spine shrinks slightly due to daylight work and influence of gravity. When the body relaxes in the morning, the spine becomes a bit flexible and the length is measured slightly more.
Why is there a difference in height in the morning and evening?
When we wake up in the morning, the space between our spinal cord, the intervertebral disc becomes slightly larger. This makes the body look a little longer. As the day increases, gravity affects the body and these disks begin to shrink, which can make a difference in height of 1 to 1.5 cm.
Doctors and fitness experts also say that it is normal to have a slight difference between the morning and evening. That is why it is considered the best time to measure height in the afternoon or evening, where it is necessary to have an exact height.
Why is this height test rule required for airhostesses and army?
Aviation industry and defense force have a fixed standard of height. For example, the minimum height for air hostess is 155 cm and separate height for men and women for recruitment in the army is fixed. If the height is measured in the morning, it can be artificially higher and the candidate can be qualified. But the evening is tested to know the real and permanent height. This ensures the right opportunity and correct selection.
