What is sleep debt?
Sleep debt, also known as sleep deficit, is the cumulative number of hours of sleep time you miss. The average recommended hours of quality sleep time for a young adult (18-25 years) is 8 hours. There are two basic ways we can deprive our bodies of the quality sleep time it needs for restoration and optimal function:
- Partial Sleep Deprivation
Consistently getting less than the optimal sleep hours
- Total Sleep Deprivation
Staying awake for longer hours, usually 24 hours or more
Effects of Sleep Debt
- Physical Health:
Chronic sleep debt is linked to serious health issues, including heart disease, diabetes, obesity, and weakened immune function. It disrupts metabolic processes and can lead to hormonal imbalances that affect appetite regulation.
- Cognitive Function:
Insufficient sleep impairs cognitive abilities, including memory, decision-making, and emotional regulation. It has been shown to increase the likelihood of anxiety and stress responses due to heightened amygdala activity in the brain.
- Mood Changes
Individuals suffering from sleep debt often experience mood swings and increased irritability. The relationship between sleep and emotional health is significant; adequate sleep helps modulate emotional responses and resilience
7 Simple Steps to A Restful Night’s Sleep
- Wake up early with the sun
Sunlight helps to increase levels of alertness, enhancing hormones such as serotonin.
- Eat a balanced diet rich in plant-based complex carbohydrates and tryptophan
Foods rich in tryptophan are good not only for sleep, but also for optimal daytime performance. Tryptophan is necessary for the production of hormones such as serotonin and melatonin ( necessary for healthy sleep and recovery).
- Moderate physical exercise
Exercise helps increase levels of some sleep-enhancing hormones.
- Avoid sleep-depriving substances such as alcohol, caffeine & nicotine
Alcohol robs the body of deep sleep, while caffeine interferes with sleep due to its stimulating properties. Tobacco users miss out on deeper sleep due to nicotine withdrawal during the night. Antidepressants and even sleeping pills can also decrease levels of REM [Rapid Eye Movement] sleep.
- Have an established, early bedtime
Experts recommend going to sleep at least 2.5 hours before midnight. A regular pattern of sleep is also important, even if you sleep during the day. Studies found that night shift workers function better with an established sleep cycle.
- Sleep in the dark
Sleeping in total darkness optimises melatonin levels.
- Leave your worries to God
Emotional stress can cause poor-quality sleep.
