Error 404, Sleep not found?

All of us have a human biological clock ticking within us, in accordance to the 24-hour rotation of the earth. Whether we are awake or asleep, this clock keeps ticking and influences all human bodily activities like metabolism, hunger, sleep, mood, etc.

This biological clock drives our circadian rhythm. Circadian rhythms can influence sleep-wake cycles, hormone release, body temperature and other important bodily functions. They have been linked to various sleep disorders, such as insomnia. Abnormal circadian rhythms have also been associated with obesity, diabetes, depression, bipolar disorder, etc.

Even minor disruptions to the circadian rhythm result in sleep disorders, where you feel difficulty in falling asleep, difficulty in staying asleep, or waking up in between sleep and not able to fall asleep again. The yearning to take a nap during the working hours keeps playing on the mind and the fatigue from the previous day still lingers on. When you start a new day with an insufficient quantity of sleep, you don’t feel refreshed and raring ahead. When this continues for a considerable period, is
termed Insomnia.

One can experience this disruption of circadian rhythm when we fly across different time zones, which we call as Jet lag. The body’s clock will eventually reset itself after a couple of days.

Insomnia sets in primarily because of lifestyle changes, travel and the associated staying in hotels and their varied bed & mattress composition, having new-born babies at home, work or personal related stress, deadlines & targets, delayed food intake, if you are on certain medication, etc. There can be further inexhaustible reasons.


As we know, most of the time, sleep disorders are mostly self-inflicted, We all hate it when we can’t sleep but can we do anything about it? Is there a cure to Insomnia? The answer is YES. A visit to a physician would solve the problem, or at worst a psychiatrist's advice would come in handy.


In so far as temporary disruptions are concerned, it might get resolved eventually, but when the problem is prolonged, it needs immediate consultation. Maybe it is an indication of an underlying physical disorder requiring urgent medical intervention lest it aggravates in severity.

Home remedies includes implementing a good sleep hygiene. This includes going to bed and waking up at the same time each day, limiting daytime sleep, and not drinking caffeine close to bedtime. It can also be important to create a routine before you go to sleep. In addition, you should avoid excessive screen time — especially before bed — as this has also been linked to insomnia.
