History and Significance of World Sleep Day

The World Sleep Society established World Sleep Day in 2008 to emphasise the importance of quality sleep. Over the years, it has gained international recognition and is now observed in over 70 countries. Here’s why it matters:

• Sleep is essential for mental and physical health, yet many people suffer from sleep deprivation.
• Rising sleep disorders affect millions, leading to chronic health conditions such as diabetes, heart disease, and depression.
• Lack of sleep impacts productivity in workplaces and schools, reducing efficiency and focus.
• World Sleep Day promotes global sleep education, helping people understand how to improve their sleep quality.

Why is Sleep So Important?

Good sleep is vital for maintaining health, energy levels, and emotional well-being. Here’s why you should prioritise sleep:

Health Benefits of Good Sleep

Sleep is essential for recharging your body and mind. A well-rested night ensures you wake up refreshed, improving your mood, concentration, and energy levels throughout the day. Here are the benefits of good sleep:

• Enhances Immunity and Fights Infection: A body with enough sleep is more able to protect itself from infections and diseases. Deep sleep creates the immune-system boosting proteins such as cytokines, fighting off the bad bacteria and viruses. Insufficient sleep can cause a weakened immune response, leading to an increased susceptibility to colds, flu, and other infections.
• Increased memory, enhanced focus and problem-solving ability: This process is important when it comes to cognitive functions because sleep can also be essential for the cognitive process. Deep sleep is when the brain processes and consolidates memories, improving learning and retention. Not only do well-rested people have an improved ability to concentrate, but also their problem-solving skills and mental clarity increase, culminating in enhanced productivity and better decisions.
• Improves mood and reduces stress: When you suffer from sleep deprivation, you feel irritated, anxious and emotionally exhausted. By controlling hormones like serotonin and dopamine, good sleep balances moods, allowing for stress regulation and reducing the chances of mood swings. It also helps in preventing mental health disorders like anxiety and depression.
• Supports Heart Health and Reduces Blood Pressure: Sleep on a regular basis might help manage blood pressure ranges and cut back stress on the cardiovascular system. Reduced sleep can increase the risk of heart disease, hypertension, and stroke. A good rest gives the heart and vascular system a time to rest which helps prevent heart problems.

Risks of Sleep Deprivation

Lack of sleep can lead to the following health problems:

• Higher Chance of Developing Diabetes, Being Overweight, and Heart Diseases: Lack of sleep disturbs hormonal balance, increasing our desire to eat high-calorie foods. It also impacts insulin sensitivity, which makes one predisposed to develop diabetes type 2. Moreover, lack of sleep is linked to high blood pressure and cholesterol levels, which in turn increases the risk for cardiovascular diseases.
• Increased Risk of Mental Disorders Like Anxiety and Depression: Sleep deprivation alters the balance of neurotransmitters, causing mood swings, stress, and an emotional roller coaster. And in the long run, this can lead to mental health problems like disabling anxiety, depression, and even mood disorders such as bipolar disorder.
• Increases susceptibility to disease and weakens the immune system: In a sleep-deprived body, there are fewer cells and antibodies that fight infection, making it much more difficult to recover from any sicknesses. Sleep deprivation leads to lower immunity so people catch common colds, flu and other infections more frequently.

How World Sleep Day Raises Awareness

International sleep day serves as a platform to inform people about common sleep disorders like insomnia, sleep apnea, and restless leg syndrome. It spreads awareness about the causes, symptoms, and preventive measures to encourage early diagnosis and treatment. Here’s what should be done during World Sleep Day: 

• Educating the public on sleep disorders and their prevention
• Encouraging workplaces and schools to promote healthy sleep habits
• Advocating for better sleep hygiene practices

Common Sleep Disorders and Their Impact

Millions of people have sleep disorders but do not know about it. Here are some of the common sleep disorders:

• Difficulty in sleeping or staying asleep: Augment fatigue and lower the productivity
• Sleep Apnea: Broken breathing can raise heart disease risk while sleeping.
• RLS (Restless Leg Syndrome): An irresistible need to move your legs that impacts your ability to sleep.
• Narcolepsy: It causes daytime sleepiness and sudden sleep attacks.
• Circadian Rhythm Disorders: Alterations of sleep-wake cycles due to shift work or jet lag.
