Celebrating World Sleep Day
Happy World Sleep Day! Established in 2008, World Sleep Day raises awareness about the importance of sleep and helps those with sleep issues. It is celebrated on the Friday before the Spring Vernal Equinox, marking the start of longer days in the Northern Hemisphere.
The Importance of Quality Sleep
According to the American Psychological Association, 2 in 3 Americans don’t get enough sleep. Over 50 million Americans suffered from sleep disorders even before the Covid pandemic, a number that has only increased. Lack of sleep leads to physical and mental strain, highlighting the critical need for good sleep.
Nathaniel Kleitman, a pioneer in sleep research, discovered REM sleep in 1953. REM sleep is a stage unique to mammals where the eyes move rapidly without transmitting visual signals to the brain. While much about sleep remains a mystery, we know it’s essential for survival.
What Happens During Sleep?
Sleep is a vital period for maintaining healthy brain function and physical health. Your body undergoes restorative processes, preparing you to face the challenges of the next day. During sleep, the immune system refreshes to help prevent illness. Sleep is as essential to human survival as food, water, and air, affecting various bodily functions.
- Cardiovascular and Respiratory Changes: Heart rate and blood pressure decrease, body temperature drops, and breathing slows down.
- Brain Activity: The brain processes information received during the day, improving concentration, memory formation, and alertness. Recent studies suggest that sleep helps flush out toxins linked to neurodegeneration.
- Gut Microbiome: The gut microbiome influences sleep through chemical messengers. The diversity of gut bacteria impacts sleep quality.
Quality sleep is crucial throughout life, supporting growth and development during childhood and adolescence and maintaining health and well-being in adulthood.
EMF and Sleep Disruption
Why aren’t we waking up feeling rested? EMFs might be the culprit. EMFs, created by electronic devices like cell phones and tablets, can negatively impact sleep. Extremely Low Frequency (ELF) and Radio Frequency (RF) radiation are the two EMF categories of concern.
- ELF: Produced by all electronic devices.
- RF: Produced by devices with antennas and wireless capabilities.
If you sleep with your phone on your bedside table, EMFs are likely affecting your sleep quality. A 2010 study by the National Library of Medicine showed that EMFs disrupt melatonin production by affecting the pineal gland, reducing melatonin levels.
Other Impacts of Technology on Sleep
Our circadian rhythm, regulating our sleep-wake cycle, is influenced by technology. Melatonin, the sleep-inducing hormone, is disrupted by blue light and EMF radiation from electronic devices. Blue light exposure, especially before bedtime, throws off circadian rhythms, causing sleep problems or insomnia.
Increased screen time has changed our habits, leading to a trade-off between sleep and physical activity. The Covid lockdowns saw a 15% increase in daily screen time. Technology makes it difficult to disconnect and wind down, blurring the lines between work and personal life. Remote work arrangements contribute to this issue, making it harder to establish boundaries.
Engaging with screens before bed overstimulates the brain, making it difficult to fall asleep. This time should be used to decompress and relax. Research shows that children and adolescents using technology before bedtime have higher body mass indexes.
Tips for a Better Night’s Sleep
- Avoid Screens Before Bed: Avoid screens for at least 30 minutes before bed. Use "Night Shift" mode or blue light glasses to reduce blue light exposure.
- Airplane Mode: Put your phone on airplane mode to eliminate RF radiation and prevent disturbances from notifications.
- Create a Sleep Sanctuary: Remove technology from the bedroom to eliminate sources of blue light and EMF radiation.
- Relax Before Bed: Practice meditation to disconnect from daily life and prepare for sleep.
- Optimize Your Sleep Environment: Keep your bedroom cool and dark. Use an eye mask and maintain a room temperature between 60-70º F (15-19º C).
- Supportive Pillow: Use a pillow that supports your head and neck and keeps your spine aligned based on your sleeping position.
- Plan Sleep Cycles: Plan your sleep in 90-minute cycles to avoid waking up during REM sleep, preventing grogginess.
- Consistent Sleep Schedule: Go to bed and wake up at the same time each day to reinforce your circadian rhythm.
- Healthy Diet: Incorporate omega-3 rich foods or supplements and maintain a diet with antioxidants, leafy greens, and healthy fats. Consider prebiotic and probiotic supplements to support a healthy gut microbiome.
By understanding and mitigating the effects of EMF and blue light, you can improve your sleep quality and overall health.
