Deep dives
The importance of sleep and light for overall health
Sleep and exposure to light are foundational elements for maintaining overall health. Sleep is crucial for neuroplasticity, the brain's ability to change in response to experience. During sleep, particularly slow-wave sleep, the brain undergoes repair and restoration processes, including the washout of neurochemical debris and neural connections involved in immune system functioning and wound healing. Napping for about 20 minutes and engaging in deliberate decompression, where the mind is allowed to relax, also contribute to neuroplasticity. Exposure to bright light in the morning and avoiding bright lights, particularly blue light, in the middle of the night help regulate the body's internal clock and promote better sleep quality. Gratitude and humor practices also play a role in increasing positive neurochemical levels such as dopamine, which can help navigate long-duration efforts and boost overall well-being.
