Understand How to sleep and eat better.
Founder of The Petit Company and Human Potential Coach, Maria A. Petit reviews book, Lights Out: Sleep, Sugar and Survival written by T. S. Wiley. In this short interview published in ShoutOut Miami, Maria saids "Junk light is a topic which unfortunately has been overlooked for far too long. Junk light like junk food for instance can also lead to disease, acceleration of ageing and weight gain. After reading this book you’ll definitely hit the sack shortly after sundown and never be caught behind a computer screen after dark or at least without your blue light blockers! Just minutes of blue light exposure before bed will delay melatonin production for hours."
The effects of light on hormones and energy are crucial to understanding the impact that light has on our health and well-being. Light exposure affects the body's circadian rhythm, which regulates the release of hormones such as melatonin, cortisol, and insulin.
Melatonin is a hormone that regulates the sleep-wake cycle and is produced in the pineal gland in response to darkness. When we are exposed to bright light, particularly blue light emitted by electronic devices, it can suppress the production of melatonin and delay the onset of sleep. This disruption in melatonin production can lead to sleep disorders and fatigue, as well as other health issues such as depression, obesity, and diabetes.
Cortisol is a hormone that is involved in the body's stress response and is released in response to stress or low blood sugar levels. Exposure to light, particularly in the morning, can help regulate cortisol levels and improve energy levels throughout the day. However, exposure to light at night can disrupt cortisol levels and lead to increased stress and fatigue.
Insulin is a hormone that regulates glucose metabolism and is important in the development of diabetes. Light exposure, particularly at night, can disrupt insulin production and lead to insulin resistance, which can increase the risk of developing diabetes.
In her review of the book, Lights Out: Sleep, Sugar and Survival, Maria A. Petit emphasizes the importance of avoiding "junk light" - the artificial blue light emitted by electronic devices such as computers and smartphones - particularly in the evening when it can disrupt melatonin production and lead to sleep disorders. She suggests using blue light blockers or avoiding screens altogether in the evening to ensure a good night's sleep and improve overall health and well-being.
Overall, the effects of light on hormones and energy are complex and multifaceted, but it is clear that exposure to light can have a significant impact on our health and well-being. By being mindful of our light exposure and taking steps to avoid "junk light" in the evening, we can improve our sleep, energy levels, and overall health.
