Why Sleep is important during COVID-19

Why sleep is important during COVID-19? The global health crisis has overcrowded our hospitals, depleted our resources, and put our government to the test. The lockdown has sent our economy whirling down with all the border restrictions coming about.

All these factors can make us stressed, anxious, and depressed. For parents who are working from home, there’s the juggle of caring for the kids and work. Children will also feel overwhelmed when taking online classes.

This stress, fear, and anxiety can cause restlessness and difficulty in sleeping. However, when we don’t get enough sleep, our bodies can’t recover in its optimal state and may not be able to function normally during the day.

Also, better sleep can boost our immune system to fight against viral infections. Here’s what you need to know how sleep affects our immune system.

Relationship of sleep to the immune system

The lack of sleep can affect your immune system and you’re more likely to catch common colds or flu viruses. Various studies from Germany found that sleep, not only repairs the tired body, but it can improve immune cells called T-lymphocytes, or T-cells for short, and the production of B-lymphocytes for antibodies.

To understand the process, we’ll break the terminologies down.

Pathogens. These are invading microbes such as germs, bacteria, and viruses.

Antigen. these are proteins found in the surface of pathogens and often serve as identification to the pathogen.

Antibodies. When the antigen enters, the body sends a signal to prevent the antigen from further attacks. The immune system releases an appropriate and unique antibody that binds itself to the pathogen and destroys it.

B-cells secrete antibodies, while T-cells fight against pathogens such as virus, flu, HIV, and malign cancer cells. T-cells produce integrins and cytokines to ward off harmful pathogens.

In short, when you don’t get enough sleep, your body produces less virus-fighting cells to keep you healthy. Also, certain proteins and cells need to be fortified when you’re already battling an infection or pre-existing medical condition.

In the long run, the lack of sleep also increases your risk of hypertension, obesity, diabetes, and heart diseases, which can be aggravated by COVID-19. If you’re not getting any ample sleep, your immune system will be suppressed.

COVID-19 affects the sleep habits of many Aussies

SARS-CoV-2 is a new pathogen

SARS-CoV-2, the virus behind COVID-19, is a new pathogen, which means, there are no antibodies to combat the virus directly. While the world is waiting for a cure, there are ways to build up your immune system naturally.

Take note that there is no known cure for COVID-19. These natural immune boosters, however, will strengthen your system to prevent the aggregation brought by the virus. It can banish common colds, beat obesity, and battle flu that can suppress the immune system.

And sleep is one natural booster.

COVID-19 affects the sleep habits of many Aussies

On the first week of September, Australia had a total case of 26,374, with recoveries at 22,719, and deaths at 770. According to the Sydney Morning Herald, about 46 percent of the 2,000 respondents are sleeping poorly during the pandemic, and 41 percent are waking up at night for three or more times a week.

The top causes for insomnia are:

  1. COVID-19 stress
  2. Job changes
  3. Financial problems

Some lifestyle-based factors aggravate sleep loss such as alcohol consumption (39 percent) and increased phone usage.

What’s interesting in the study is that 42 percent of people, who slept badly before, improved their restfulness because they sleep in a routine best suited for their needs.

For instance, people who get up early to commute find their sleeping patterns better when they work from home. Researchers also found out that these respondents get to eat breakfast at a time ideal for their body growth and development.

Nonetheless, sleep experts found a surge of first-time patients seeking help with their sleep problems. Employees who have been laid off from work found themselves anxious and suffering from shortness of breath as a response to stress.

If we can’t control our actions, feelings, and thoughts, we might raise our stress levels. You can learn to tap your thoughts positively by meditating. Calm yourself down with deep breaths before tackling the tasks one by one. You can even have a positive mantra for yourself to boost your confidence, such as, “I’m strong, I’m capable, and I’m organized.”
