We are taller in the morning than in the evening because during normal activities during the day the cartilage in our knees and other areas slowly compress, but when you go to sleep and rest the cartilage goes back to normal. On average we are about 1cm taller the morning than in the evening.

The other component to this phenomenon is that the joint capsules loose some of their synovial fluid and the connective tissues around the joints tend to become compressed throughout the day from activity and trying to counter the affects of gravity.

Also, the discs of the spine do the same thing. During the night, they resorb more fluid making them thicker and the person taller. While walking or being upright during the day, they slowly lose some of this fluid and become thinner.

Adults are approximately 1cm (2/5 inch) taller in the morning than the evening as by the evening the intervertebral discs have been compressed slightly.

You are taller in the morning.

yesAnswerYes, you are about 2-3 cm or 3/4 inches taller in the morning due to vertebral decompression which allows the spinal discs to expand overnight.AnswerYes.I'm 5'10 in the evening and at the morning i am 5'11.5.So in the morning if you had a 8-10 hours sleep you can be about 1-2 inches in the morning!

If you are finding it harder to concentrate in the evening than in the morning, then presumably you are tired after your exertions of the day, and you need to rest. Note that not everybody has greater difficulty concentrating in the evening than they do in the morning. There are morning people and there are night people. It depends upon how your life is organized, how much coffee you drink, and so forth.

Were taller during morning but I don't know why.... Francis...

8am is morning. AM is morning whilst PM is afternoon/evening.

Certainly it is more cheaper to set heating for two hours morning and evening rather than to set it for all day long.

Noon is hotter than morning or evening because at that point of the earth's daily rotation, that part of the earth is closer to the sun and is angled more towards it.

Evening or morning is Venus! There u go!

it is actually both the morning and evening star

Reduced gravity allows the disks in the spine to expand. It is the same reason that you are taller when you first get out of bed in the morning.

The Morning and Evening star IS A PLANET. The planet Venus.

twilight is inthe evening.

Venus is the evening star

The duration of Lora from Morning Till Evening is 1.55 hours.

Earth and Venus. From Earth Venus and Mercury are planets visible as "morning" and "evening" stars. From Venus, Mercury would appear in the morning and evening sky. From Mars I would expect Earth, Venus, and Mercury to all be morning and evening "stars."

Venus is the morning star or the evening star, depending on where Venus is in its orbit.

Depending on where it is in its orbit, Venus could be either the morning star or the evening star.

Yes, morning and evening are best times.

Not necessarily. Though some appear as morning and evening 'stars'. Venus for example.

The average person doesnt shrink at all, but they are normally about a 1/2 inch to a full inch taller in the morning than they are in the evening due to the compaction of the vertabrea in the back over the durition of the day due to gravity.
