What is melatonin?

Melatonin is a hormone that our bodies produce naturally.  It helps to regulate our body clock.  When it gets dark outside as night time comes melatonin is released in to our brains to make us feel tired so that we can go to sleep.  In the morning when the sun rises the melatonin level in our brains drops and so we are able to wake up.

 

Melatonin levels

Melatonin levels decrease as we get older.  This is why older people usually get up early!  Teenagers have high levels of melatonin and thus like their sleep ins!

If someone doesn’t have enough melatonin they can have trouble getting enough sleep.  Aging is one cause of lowered melatonin levels.  Stress and staying up late can also lead to lower melatonin.  There are lots of medicines that can also decrease our melatonin levels.
