Even after 8 hours, exhaustion can persist if sleep quality is poor. Deep sleep facilitates a 'glymphatic brain wash,' crucial for flushing out waste proteins. This video highlights that quality over quantity of sleep is paramount and will reveal how to achieve it by addressing temperature, light, sound, air, chemistry, and diet.
To facilitate sleep, your core body temperature naturally drops by 2-3 degrees. Keeping your room between 60-67°F (with 65°F being ideal) helps achieve this. A hot shower or bath 90 minutes before bed can also aid cooling by inducing vasodilation, allowing the body to lose heat. Ensure your feet stay warm, as cold feet can hinder sleep.
Dimming lights 2-3 hours before bed promotes melatonin production. Avoid blue light from screens (TVs, phones) by using orange/amber glasses or disabling small indicator lights in the bedroom. Natural light, like a campfire's warm glow, is therapeutic, while LED and phone screens before bed are detrimental. Early morning sun exposure for 30 minutes helps set your circadian rhythm.
Avoid snacking, especially refined carbohydrates, before bed, as this can cause blood sugar fluctuations throughout the night. Magnesium (particularly magnesium glycinate) can help with muscle tightness and sleep. Glycine (3 grams) can also assist. Limiting caffeine intake later in the day is crucial, as the liver takes time to detoxify it. Alcohol also negatively impacts sleep. Adding sufficient salt to your last meal can prevent cortisol spikes and improve sleep.
Complete silence can signal danger, potentially causing insomnia. White noise machines (fan, water, rain sounds) can provide a constant, soothing background. Earplugs can buffer sudden noises. Good air quality is essential; cracking a window for ventilation or having plants in the room ensures adequate oxygen and reduces carbon dioxide buildup, promoting a restful state.
Practice nasal breathing (4 seconds in, 4 seconds out) to calm the nervous system. Supplementing with B1 can help with excessive thinking, nightmares, or vivid dreams. Avoid eating 3 hours before bed, especially sugary carbs, as this can suppress growth hormone production, which is vital for repair and fat burning. Keep cell phones out of the bedroom or away from your head to avoid electromagnetic field interference. Daily walking can also help reduce cortisol during the day, contributing to better sleep at night.
