Waking Up Late Means Moving Less

Our various biochemical signals, daily lifestyle, and genetic inclinations develop a specific chronotype in us, that is basically our overall biological response to the outside world.
These chronotypes are categorized as: Morning, Day or Night. The person with a morning chronotype will wake up early in the morning and start to feel hungry sooner than the person with a Day or Night chronotype.

Our Chronotype

The chronotypes we form are not permanent in most cases but have a rhythm of their own, spawning years, and shifting from Morning to Day and eventually, Night, based on our age.
People with chronotypes that are more towards the evening are more prone to various metabolic disorders and are likely to develop obesity, diabetes and heart disease.

The Body Rhythm

A major study in the University of Oulu, Finland showed that people with the morning chronotype moved for about 20 to 30 minutes more than those with the other chronotypes.
This study suggests that people who stay up late and eventually wake up late need to take their exercise routines more seriously.

Early risers did the equivalent of walking 20 to 30 minutes more each day compared to “evening types,” who tend to stay up late.

People who are evening types go to bed later and wake up later than morning types.

The study, one of the first to objectively track daily movements of a large sample of early birds and night owls, suggests that knowing our chronotype might be important for our health.
