Sleep is important for good health. Good sleep improves brain performance, mood and health.

Numerous illnesses and disorders are more likely to develop in people who do not get enough sleep on a regular basis. Lack of sleep may cause obesity and dementia and sometimes lead to heart disease and stroke.

A good night’s sleep is extremely vital for your health. In fact, it is just as crucial as eating a well-balanced diet and exercising.

Although each person has distinct requirements, most people require 8 to 10 hours of sleep per night.

Sleep deprivation can jeopardise your health. ‘To lead a healthy life, make sure you prioritise your health and sleep.’

Sleep deprivation might make you irritable the next day. Over time, not getting enough sleep might affect your mood throughout the day.  Enough sleep helps regulate blood sugar and maintain overall well-being. Enough sleep on a regular basis helps you improve everything from the blood sugar to workouts.

10 reasons to get good sleep

The following are just a few of the numerous advantages that health professionals link with having a good night’s sleep.

Weight management

The relationship between obesity and inadequate sleep are unknown.

People who sleep less than seven hours each night are more likely to have a higher BMI and develop obesity. Lack of sleep also leads to weariness.

Improve concentration

Sleep is essential for brain function. Sleep deprivation has a detrimental impact on cognition, focus, productivity and performance. Getting enough sleep boosts the concentration power of children, adolescents and young adults to help them perform better in academics or sports.

Sleep also improves problem-solving abilities and memory performance in both children and adults.

Improve athletic performance

Sleep has been demonstrated to improve athletic performance. Sleep enhances motor skills, reaction time, muscular power, endurance and problem-solving abilities.

Sleep deprivation may decrease your motivation to workout. Sleep is essential for athletes because it allows the body to recuperate. Other advantages of good sleep include:

  • Improved endurance
  • Good concentration power

Heart health

Sleep deprivation may increase your chance of getting heart disease.

Furthermore, brief sleep tends to raise the risk of hypertension, particularly in people with obstructive sleep apnea, a disorder characterised by disrupted breathing while sleeping.

Risk of diabetes

Type 2 diabetes may also arise due to inadequate sleep.

Sleep deprivation can result in physiological changes such as lower insulin sensitivity, increased inflammation, changes in hunger hormones and behavioural changes such as poor decision-making and increased food consumption, all of which can raise the risk of diabetes.

In addition, lack of sleep has been related to a higher risk of obesity, heart disease and metabolic syndrome. These variables also raise your chances of developing diabetes.


Depression and other mental health issues are significantly linked to poor sleep quality and sleeping problems.

In general, people with anxiety and depression may have a low quality of sleep than those who don’t have anxiety and depression.

On the other hand, people who suffer from sleeping disorders such as insomnia or obstructive sleep apnea have higher rates of depression than those who do not.

If you have sleeping difficulty and realise that your mental health has deteriorated, you must consult a healthcare expert.

Immune system

Sleep deprivation has been found to affect immunological function. Getting enough sleep may help your body’s immune response to vaccines.


There is a connection between obtaining enough sleep and lowering inflammation in the body. Inconsistent sleep and going to bed at different times can disrupt the body’s process of regulating inflammation while sleeping.

Affects emotions

Sleep deprivation impairs your capacity to regulate emotions and interact socially. Tiredness might also impair the ability to respond to humour and demonstrate empathy.

Prioritising sleep could help you strengthen your interactions with others and to become more social.

Sharper brain

When you’re sleep-deprived, you’ll likely have difficulty retaining and recalling things. Good sleep is essential for both learning and memory. It isn’t easy to focus and absorb new knowledge when you don’t get enough sleep. Sleep allows your brain to catch up and prepare you for what comes next.


Getting enough sleep is essential for overall health and well-being. Adequate sleep can help improve mood, boost energy levels and enhance cognitive function. Additionally, research has shown that getting enough sleep can help to reduce the risk of certain chronic health conditions, such as obesity, diabetes, and heart disease. It is crucial to ensure you get the recommended amount of sleep each night.

On an average, take 7-8 hours of sleep every night to lead a healthy life.
