Do you get a good night's sleep?

How many hours of sleep do you really need every night? Well, a good night’s sleep, as defined by experts, is a sound and deep sleep, without dreams or with dreams you don’t remember when you wake up. Ideally, it should be undisturbed by noise, harsh lights, etc.

It’s Sunday morning, 9.30 am. You’ve had nine hours of sleep and are feeling very fresh. Or are you? Do you think you could have slept longer? Even though you’ve had nine hours? Surely that’s adequate?

Well, yes and no, say experts. A good night’s sleep has to be measured in terms of quantity and quality. "There are no set standards," says Dr Nevin Kishor, senior consultant, pulmonology, Max Healthcare. "While it is necessary to get adequate hours of sleep, the sleep also needs to be completely restful or you won’t feel refreshed."



A good night’s sleep, as defined by experts, is a sound and deep sleep, without dreams or with dreams you don’t remember when you wake up. Ideally, it should be undisturbed by noise, harsh lights, etc. Just as important, you should sleep like this for six to eight hours. That’s the optimal level of sleep for working adults, says Dr Kishor.



The right doze

Optimal levels of sleep can’t be defined. They vary from individual to individual and depend upon age (see box). But if you don’t allow yourself adequate sleep, you may suffer sleep deprivation.



insomnia"There are people who do with fewer hours of sleep than prescribed and yet are full of energy," says Dr Kishor. "If they are not feeling stressed and sleepy and their bodies are not shouting, they are good to go with just a few hours. But most people need a certain amount of sleep to function properly."

A good night’s sleep revitalises the body by revitalising the mind, says chest and sleep specialist Dr Madhusudan Das. “All our physical functions are directly or indirectly related to the mind, i.e., the brain,” he says. Sleep deprivation can cause:
Lapses in memory
Constant fatigue
Slowing down of mental and physical functionality
Weight gain or loss
Anxiety and irritability
Headaches
Impaired immune system
Muscle fatigue and pain
These symptoms are most prominent among people aged between 25 to 50 years, says Dr Das. “These are the ‘working years’ when the mind and body function vigorously.”
