Do you know that you have a body clock inside you? This clock is responsible when you are unable to sleep and are up at 3 or 4 in the morning. This is the culprit behind your laziness and inability to get up early morning.
Everybody has their own sleeping and waking issues. Some people can’t take naps in the day, while others can’t keep their eyes open past 10 pm. In the morning, many people wake up at the same time every day – sometimes even before their alarm rings.
This clock depends upon light to make decisions
The light that you see is conveyed by your optic nerve to several parts of your brain, one of which is the pineal gland. In the daytime, when there’s plenty of light, your pineal gland yields less melatonin, and at night, when there’s less light, your pineal gland produces more melatonin. Melatonin is the hormone that makes you sleep. In the morning, your SCN senses light and activates the release of hormones like cortisol, and train your brain to increase your body temperature. The joint effect of these two processes wakes you up.
This clock started working from earlier months of your life
Located in the suprachiasmatic nuclei (SCN) of the hypothalamus, your body clock controls your circadian rhythms, which are 24 hour cycles of sleeping and waking. These are regulated through body temperature and the secretion of hormones related to sleep.
This clock is programmed differently in teenage
Teenagers experience a sleep phase delay because their melatonin levels rise later in the evening than most adults and young children. This makes it difficult for them to fall asleep before 11 pm. Their circadian rhythm tends to dip between 3:00-7:00 in the morning and 2:00-5:00 in the afternoon.
This clock gets hurt by Electronic devices, and working in shifts
Electronics affect your body clock because they emit artificial light that confuses your system and affects your brain’s ability to calculate the correct time to go to sleep.
Research shows that people who work in shifts are at a greater risk for several major health problems because of their irregular sleep schedules.
