Have you ever wondered  why the sun must go down at the end of the day ? Have you ever wondered why when a day is finished darkness must follow?

BECAUSE NATURE WANTS US TO GO TO SLEEP AT NIGHT!

One of the  reasons we are able to survive  is because we sleep every night. When we sleep, the body  enters the phase of repair, restoration, regeneration and rejuvenation. During sleep, cells repair and clear out metabolic waste products, tissues regenerate, endocrine organs realign and reconnect again, memory circuits consolidate, hormones re balance, ….

And the grand switch to sleep is the substance called melatonin. Melatonin is produced by the pineal gland in the brain. Melatonin switches on the sleep cycle. As we enter dusk, natural light diminishes and the light sensitive receptors in the retina of the eyes send signals to the pineal gland to active the production of meletonin, which helps to initiate sleep. When morning comes, natural light enters the eyes and activates the retinal light receptors which send signals to the pineal gland to switch off melatonin production, so that we could exit the sleep cycle. This is one of the many aspects of the famous ” circadian rhythm”.

The invention of electricity and artificial lighting means our retina is exposed to light for a much longer period each day than nature intended. Hence the term “light pollution” is derived. To combat the rising rate of insomnia and sleep deprivation in our society, restriction to light exposure at night and setting good bed time hygiene practices  is paramount. This is especially important for young children in terms of their development as growth hormone is secreted during sleep.

Try some of the bed time hygiene practices listed below, and observe the positive changes in the body.

  1. Setting a routine bed time, preferably before 11pm (earlier the better, before 9pm for children)
  2. Dimming light or wearing sunglasses one hour before going to bed
  3. Restriction on using electronic devices before bed
  4. Natural light exposure in the morning
