Being tired could be as a result of many different factors or habits. Sleep is one of the most important factors that allow our bodies to function at maximum capacity. When we don’t get enough sleep or when we haven’t slept in a while our bodies tend to feel tired. Almost every living organism on Earth needs sleep and even though our sleep cycles may vary we all have that in common. Getting alot of sleep ensures that we have enough energy to complete our daily tasks.
Some animals need more sleep than others and can also sleep in different locations , postures or positions . The Sloth spends majority of it’s life sleeping and Koalas need around 18 hours of sleep per day and horses sleep are able to comfortably sleep on their feet. The amount of sleep a human needs is directly related to their age. A toddler needs between 14-17 hours of sleep daily and kids need around nine and a half hours of sleep daily meanwhile, an adult needs around 5-7 hours of sleep per day. We spend two thirds of our lives sleeping.
Our brain regulates when it’s time for us to go to sleep and when we should stay awake. When we haven’t had enough sleep or when we stay awake for too long sleeping signals “creep” into our waking brain signals This causes a sudden feeling of drowsiness that in most cases, won’t go away until we sleep.
The Circadian rhythm is like a natural clock in our bodies. It controls the production of Melatonin which is a hormone that helps to tell your body when to go to sleep and when to wake up. The more Melatonin your body releases, the more tired you will feel. When our bodies see light , our brain sends the signal to help us stay awake but when our bodies see darkness our brain sends the signal telling us that we need to go to sleep.
