Sleep is a critical component of health, and a lack of quality sleep can cause disruptions—great and small—in your overall health. While an occasional lack of sleep may not seem like a big deal, its impact can be intense and its effects can linger. If you make it a habit, not sleeping enough can have severe consequences on your health. Sleep deprivation can negatively impact your judgment and cognitive ability. Not getting enough sleep can put you at risk of making poor decisions, such as driving when not mentally alert. Experts recommend that adults get between seven and nine hours of sleep each night.

Sleep deprivation can cause an increase in stress hormones, negatively impacting your judgment and cognitive ability
Sleep deprivation can have a detrimental impact on your judgment and cognitive abilities. It can impair your ability to make sound decisions and increase the likelihood of engaging in risky behaviours.
When you are sleep-deprived, your body experiences an increase in stress hormones like cortisol, which can have negative consequences on your health. High cortisol levels have been linked to high blood pressure and other health concerns. Sleep deprivation also affects your brain's frontal lobe functions, including judgment and impulse control, which can lead to poor performance at work or school and changes in your ability to make decisions and control impulses.
The impact of sleep deprivation on your cognitive abilities can be seen in various aspects of your daily life. For example, it can make you more forgetful and prone to misplacing things. It can also affect your ability to focus and concentrate, further weakening your memory. This can impact your performance at work or school, as you may find it challenging to complete complex tasks or engage in logical reasoning.
Additionally, sleep deprivation can alter your mood and emotional state. It can make you more irritable and angry and impair your ability to manage your emotions effectively. You may also find it more difficult to cope with stress and understand and communicate with others.
Chronic sleep deprivation can have long-term effects on your health and well-being. It can negatively impact your immune system, making it harder for your body to fight off infections. It can also lead to an increased appetite and cravings for sugary and carbohydrate-rich foods, which can impact your nutritional intake and contribute to weight gain.
Therefore, it is crucial to prioritise sleep and aim for the recommended seven to nine hours of sleep per night for adults. Practicing good sleep hygiene, such as maintaining a consistent sleep schedule and creating a conducive sleep environment, can help improve your sleep quality.

Lack of sleep can lead to an increased risk of chronic diseases and early death
Sleep deprivation can lead to an increased risk of chronic diseases and early death.
Sleep is critical to your health. The amount of sleep you get can affect everything from weight and metabolism to brain function and mood. Sleep deprivation can negatively impact your judgment and cognitive ability. Not getting enough sleep can put you at risk of making poor decisions, such as driving when not mentally alert.
Chronic sleep deprivation puts you at a higher risk of falling asleep at the wheel, which accounts for about one in six fatal crashes. It can also cause reduced immunity, high cortisol, increased appetite and cravings for sugar and carbs, skin changes, and chronic inflammation.
Moreover, sleep deprivation can lead to an increased risk of certain conditions like high blood pressure, obstructive sleep apnea, conditions that involve psychosis, diabetes, and heart disease.

Insomnia is a common sleep disorder that affects around 10% of the world's population
Acute insomnia typically lasts a few days or weeks and can be caused by external factors such as stress, a change in environment, or a significant life event. If acute insomnia persists for several months, it becomes chronic insomnia. Chronic insomnia is diagnosed when a person experiences sleeping difficulties and related daytime symptoms such as sleepiness and attention issues, at least three days a week for longer than three months. It is estimated that about 10-15% of people suffer from chronic insomnia.
Insomnia can have various negative consequences on one's life, including fatigue, impaired memory, and irritability. It can also lead to a decline in work or school performance and increase the risk of accidents. Additionally, insomnia that goes untreated and results in long-term sleep deprivation is linked to a higher risk of substance abuse, chronic pain, heart disease, and diabetes.
There are several treatment options for insomnia, including cognitive-behavioural therapy and medication. Maintaining healthy sleep habits, such as sticking to a consistent sleep schedule and limiting substance use, can also help manage insomnia.

Sleep needs vary throughout a person's lifetime, with infants requiring the most sleep
Sleep needs do indeed vary throughout a person's lifetime, and this is influenced by a combination of genetic, physiological, and environmental factors. On average, newborns require the most sleep, with their sleep needs gradually decreasing as they grow older.
Newborns (aged 0–3 months) typically sleep between 14 and 17 hours per day. This is because they are yet to develop an established circadian rhythm, and their sleep is distributed across a 24-hour cycle. From 4 to 11 months, infants require 12 to 16 hours of sleep, including naps. This gradually decreases to 10 to 14 hours for young children (aged 1–5 years), and 9 to 12 hours for school-aged children (aged 6–12 years).
For teenagers (aged 13–18 years), the recommended sleep duration is 8 to 10 hours. This is a time when intrinsic factors, such as pubertal hormonal changes, and extrinsic factors, like increased exposure to artificial light and technology, can disrupt sleep patterns.
For adults (aged 18–64 years), the recommended sleep duration is 7 to 9 hours. However, it's important to note that sleep needs can vary among individuals due to factors such as genetics, work demands, and health conditions.
Finally, older adults (aged 65 years and above) typically need 7 to 8 hours of sleep. This decrease in sleep duration is often due to comorbidities, medications, and sleep-related disorders rather than the aging process itself.
While these are general guidelines, it's worth noting that optimal sleep duration can vary from person to person and may be influenced by factors such as genetics, daily routines, and health status.

Practicing good sleep hygiene can help improve sleep quality
Sleep hygiene refers to both your sleep environment and behaviour. Good sleep hygiene includes setting a strict sleep schedule, following a bedtime routine, forming healthy habits, and optimising your bedroom for sleep.
Set Your Sleep Schedule
- Have a fixed wake-up time: Try to wake up at the same time every day, even on weekends. This gets your brain and body accustomed to getting the full amount of sleep that you need.
- Prioritise sleep: Avoid skipping sleep to work, study, socialise, or exercise. Calculate a target bedtime based on your wake-up time and stick to it as closely as possible.
- Make gradual adjustments: If you want to shift your sleep times, do so gradually in small steps to give your body time to adjust.
- Don't overdo it with naps: While naps can be energising, they can disrupt your sleep at night. Keep naps short and limited to the early afternoon.
Follow a Nightly Routine
- Keep your routine consistent: Following the same steps each night reinforces that it's bedtime.
- Budget 30 minutes for winding down: Engage in activities that calm you, such as light stretching, reading, or relaxation exercises.
- Dim your lights: Bright lights can hinder melatonin production, a hormone that facilitates sleep.
- Unplug from electronics: Blue light from electronic devices can decrease melatonin production and keep your brain alert. Avoid screens for 30-60 minutes before bed.
- Test methods of relaxation: Instead of focusing on falling asleep, try meditation, mindfulness, or paced breathing to relax your mind.
Cultivate Healthy Daily Habits
- Get daylight exposure: Light, especially sunlight, is a key driver of circadian rhythms that encourage quality sleep.
- Be physically active: Regular exercise improves sleep quality and delivers other health benefits. However, avoid exercising close to bedtime as it can increase your energy levels and body temperature.
- Don't smoke: Nicotine disrupts sleep.
- Reduce alcohol consumption: Alcohol may help you fall asleep, but it disrupts sleep later in the night.
- Cut down on caffeine in the afternoon and evening: Caffeine is a stimulant that can keep you wired when you want to rest.
- Don't dine late: Eating late or having a heavy meal close to bedtime can disrupt sleep.
Optimise Your Bedroom
- Have a comfortable mattress and pillow: A comfortable sleeping surface is crucial for pain-free sleep.
- Use excellent bedding: Choose sheets and blankets that match your preferences.
- Set a cool yet comfortable temperature: A cooler temperature of around 65°F (18.3°C) is ideal for sleep.
- Block out light: Use heavy curtains or an eye mask to prevent light from interrupting your sleep.
- Drown out noise: Use earplugs, a white noise machine, or a fan to block out bothersome sounds.
- Try calming scents: Light scents like lavender may induce a calmer state of mind and create a positive space for sleep.
By practicing good sleep hygiene, you can improve your sleep quality and overall health.
