Sleep problems can have a domino effect when it comes to your health
We’ve all experienced a bad night’s sleep. Whether it’s from staying up too late, or just tossing and turning, the exhaustion that comes from poor sleep can be tough to deal with the next day.
However, the impacts of sleep deprivation go far beyond simple tiredness. Poor sleep, especially if it’s a long term problem, can have significant consequences on both your physical and mental wellbeing.
Sleep loss in numbers
The Sleep Council’s “Great British Bedtime Report” highlights a concerning trend: as many as one-third of UK adults are getting just 5-6 hours of sleep per night, significantly less than the recommended 7-9 hours for adults.
This makes sleep deprivation a serious and wide-reaching health concern. We’re going to take a closer look at the dangers of sleep deprivation, exploring why it’s so important for you to prioritise the rest you need, and what steps you can take to get it.
The physical health risks of sleep deprivation
Cardiovascular disease
A continuous lack of sleep has been directly linked to an increased risk of cardiovascular diseases. The British Heart Foundation notes that poor sleep patterns can lead to high blood pressure, increased cholesterol, and a greater likelihood of coronary heart disease. Essentially, when you skimp on sleep, your heart pays the price.
Obesity and diabetes
The relationship between sleep deprivation and weight gain is well-documented. The Royal Society for Public Health (RSPH) warns that insufficient sleep affects the hormones that control appetite, leading to increased hunger and a preference for high-calorie foods.
What’s more, the risk of Type 2 Diabetes escalates with shorter sleep durations, as the body’s ability to regulate sugar becomes compromised.
Immune function
Your immune system relies on sleep to stay healthy. The NHS advises that those who don’t get enough sleep are more likely to catch infections, such as the common cold, and may experience a slower recovery from illness. This is because sleep enhances the body’s ability to respond to pathogens and recover.
The mental health concerns surrounding sleep loss
Anxiety and depression
The Mental Health Foundation has found a strong link between sleep deprivation and the development or exacerbation of mental health issues, including anxiety and depression.
When we miss out on sleep, our mood suffers. Problems seem more insurmountable, and negative emotions are felt more keenly. Getting enough sleep is critical for regulating mood and emotional resilience.
Cognitive impairment
Lack of sleep can severely impact your cognitive processes, impairing attention, concentration, reasoning, and problem-solving. This can lead to decreased performance at work or school, increased errors, and even accidents.
The RSPH highlights that sleep-deprived individuals are much more likely to be involved in car accidents, highlighting the serious risks bad sleep can pose.
How to prioritise better sleep
Acknowledging the importance of sleep is the first step to enjoying higher quality rest. Some of the simple steps you can take to improve your sleep include:
- Establishing a routine: Going to bed and waking up at the same time every day can significantly improve the quality of your sleep.
- Creating a restful environment: Ensure your bedroom is quiet, dark, and at a comfortable temperature. Investing in a good quality mattress and pillows can also make a big difference.
- Limiting screen time before bed: The blue light emitted by screens can interfere with your ability to fall asleep. Try to avoid screens for at least an hour before bedtime.
- Mindful eating and exercise: Avoid heavy meals, caffeine, and alcohol before bedtime. Regular physical activity can help you fall asleep faster and enjoy deeper sleep.
By prioritising sleep and adopting healthier sleep habits, you can significantly improve your overall health and wellbeing.
