What is Sleep Debt?

Have you ever had a night of poor sleep and tried to catch up on it the next day by sleeping in? Or perhaps you consistently sacrifice sleep to meet work or social demands? Unfortunately, in this fast-paced society, many of us prioritise productivity over rest, leading to what’s called “sleep debt”. Similar to financial debt, sleep debt accumulates over time when we don’t get enough sleep and can have serious consequences. In this article, we’ll talk about what sleep debt is, how it affects our health and provide practical tips to help you pay off your sleep debt and maintain a healthy sleep routine.

What is Sleep Debt?

Sleep debt, also known as sleep deficit, is the accumulated difference between the amount of sleep your body needs and the amount of sleep you actually get. Simply put, it happens when you consistently fail to get enough sleep, causing your body to become sleep-deprived. Over time, this sleep deficit adds up and must eventually be paid off. If you don’t catch up on your sleep debt, it can have negative consequences for your health and well-being.

Having a busy work or school schedule, taking care of young children, using electronic devices in bed, poor sleep hygiene, sleep disorders and illnesses are some of the many factors that can contribute to sleep debt.

How Do You Calculate Sleep Debt?

To calculate your accumulated sleep debt, simply subtract the amount of sleep you get from the amount your body needs each night and then add up the total amount of sleep you missed over the course of multiple nights.

For example, if your body requires 8 hours of sleep but you only get 6 hours of sleep on Monday night, you have accumulated a sleep debt of 2 hours for that night. Let’s say you get 7 hours of sleep on Tuesday night, but your body still needs 8 hours. You now have an additional sleep debt of 1 hour for Tuesday night, bringing your total sleep debt to 3 hours (2 hours from Monday night and 1 hour from Tuesday night).

You can continue to calculate your sleep debt in the same way for each night. The goal is to pay off your sleep debt by getting the amount of sleep your body needs each night, so you can feel rested and alert during the day.

Signs of Sleep Debt

Sleep debt can lead to sleep deprivation, which can affect both our physical and mental health in many ways. It’s important to be aware of the signs of sleep debt so that you can identify and address any issues before they become chronic. Here are some common signs to look out for:

● Daytime sleepiness
● Fatigue
● Headaches
● Poor concentration & memory
● Mood swings
● Decreased physical strength

Some serious long-term effects of sleep deprivation due to chronic sleep debt include:

● Microsleeps (brief periods of sleep that occur when someone is normally awake and performing a task)
● Cardiovascular problems (i.e. hypertension, heart attack and stroke)
● Obesity
● Diabetes
● Weakened immune system
● Depression & Anxiety

How To Recover From Sleep Debt

It may take several days or even weeks to pay off significant sleep debt. Although challenging, recovering from sleep debt is possible. Here are a few tips to get you started on catching up on sleep and getting rid of sleep debt:

● Go to bed at least 15 minutes earlier than your usual bedtime
● Take a short nap (10 to 20 minutes)
● Sleep in on your days off
● Exercise during the day

How To Avoid Sleep Debt

If you’re looking to avoid sleep debt, there are a few simple steps you can follow.

Firstly, prioritise getting enough sleep – aim for the recommended sleep hours for your age and lifestyle. It’s also important to establish a regular sleep routine and stick to it, even on the weekends. That means going to bed and waking up at the same time every day.

Creating a relaxing bedtime routine is also key to avoiding sleep debt. Whether that means reading a book, taking a bath, or meditating, the goal is to find an activity that helps you relax.

Additionally, creating a sleep-conducive environment by investing in a good mattress and keeping your bedroom clean, cool, dark and quiet would also help you drift off to sleep more easily.

Furthermore, if you’re prone to consuming caffeine or alcohol, try to avoid them in the hours leading up to bedtime. And most importantly, try to limit your exposure to screens before bed. The blue light emitted by cellphones, laptops and TVs can disrupt the production of the sleep hormone melatonin, making it more difficult to fall asleep.

Conquering Sleep Debt by Prioritising Sleep

In conclusion, sleep debt is a common phenomenon that many of us experience in our busy lives. When we don’t get enough sleep, our bodies accumulate a sleep debt, which can have both short-term and long-term effects on our health and well-being. The good news is that we can recover from sleep debt by prioritising our sleep and making it a part of our self-care routine. So, let’s give ourselves the gift of sleep and wake up feeling refreshed, recharged, and ready to take on the day.

On another note – if you think your mattress is the main reason why you cannot fall asleep or achieve quality sleep, maybe it’s time to invest in a new one that actually meets your needs. Take our mattress selector quiz below or shop our full range to learn more about Sealy mattresses!
