Our body has an inbuilt clock. It reminds us to eat and to drink from time to time to nourish ourselves. It also tells us when to sleep and faithfully wakes us in the morning at a fixed time each day. Interestingly the sleep trigger seems to be linked to the amount of light that is present.
It is well known how important sleep is for the overall well-being of a person. Sleep too little and you feel groggy and confused. Sleep too much and you feel lethargic and lazy. Sleep is necessary for the body to rest, rejuvenate and re-energise itself. It is when we are in the deepest sleep that we get the most refreshed. Meditation, if practiced regularly and properly, can refresh our minds sufficiently and help us cut down on sleep.
In modern world, it is fashionable to play with sleep. Some of us sleep too late for we have so many things to to - like completing tasks or watching television (the best programs are late in the night) or attending parties or entertaining ourselves in different other ways. Some of us sleep too little because we want to get as much as possible from our daily 24 hours. This can often be counter productive.
Excessive sleep and lack of sleep are both dangerous. They have an impact on our attitudes and our behaviour. We may become indifferent, casual, lazy, rude or irritable if we do not sleep well. Each body is tuned to get a certain amount of sleep (typically 6-9 hours). We must make sure that this is not sacrificed or compromised for it can affect our health and capability to think coherently & lead a life of values.
