The luxury commodity of sleep. Why is it important?
May 10, 2021
The average Pole spends 25-35% of their life in bed. We often don't realize how important good-quality sleep is for our bodies. A deficiency can worsen our quality of life, and in extreme cases, prolonged sleep deprivation can lead to serious health consequences. Why is sleep so important?
The brain never sleeps
When you go to sleep, your brain continues to work. The brain is a mine of information, a library of data. During sleep, increased cell regeneration occurs, which can be described as a cleansing process for the mind. This means that new synapses (neural connections) are formed and redundant ones are removed. Spaces are created for new memories.
Sleep disorders disrupt this process, contributing to memory loss, poor concentration and well-being, as well as a temporary "disconnection" of the brain – hence so many accidents among professional drivers.
It is worth adding that sleep is also, above all, a time for regeneration and reconstruction of our tissues and muscles.
The entire body rests. During this time, important amines and hormones are also produced.
Negative effects of sleep deprivation
Remember that when it comes to sleep, it's not so much the length but the quality that matters. As we age, our sleep needs decrease, which is why newborns sleep up to 20 hours a day, while older adults only need 5-6 hours to fully regenerate.
So what negative effects of sleep deprivation might you notice?
- Deterioration of physical condition – less sleep means less time for muscle regeneration, you achieve worse results during increased exercise.
- Long-term memory and speech disorders – you experience so-called memory lapses, you miss words, you speak unclearly (babble), you repeat yourself, your brain works more slowly.
- Your mood changes – you become irritable and absent-minded. Your well-being worsens, and you lack motivation. Long-term sleep problems lead to anxiety and even depression.
- Your immunity decreases – you become more susceptible to minor infections and experience headaches more often.
- You gain weight – lack of sleep leads to metabolic disorders, which makes you eat more and reach for unhealthy foods more often.
- You lose control of your body – sleep deprivation can cause hallucinations, you start seeing double, and you can no longer distinguish between imagination and reality.
What influences sleep quality?
Everything! Above all, however, lifestyle, stimulants, and stress. The quality of sleep is certainly influenced by our immediate surroundings, but so are the rituals we engage in before sleep.
What to do to sleep better?
- Avoid heavy meals right before bed. Eat dinner 2-3 hours before bed.
- Ensure proper conditions in your bedroom – draw curtains or blinds, close windows (air the room first), turn off the lights. Ensure peace and quiet.
- If your partner snores, get some earplugs.
- Turn off the TV, put away your phone – the blue light emitted from screens stimulates your brain instead of calming it down.
- Give up stimulants – coffee, tea and cigarettes.
- Buy a medium-firm mattress that relieves the spine and allows you to relax.
