Taurine found in the RedBull drink and body building supplement will help repair the damage bright light carries out on your eyes, its also a nootropic helping users to lay down memories when they sleep, dream frequency including remembering dreams will also increase, dreaming is a sign that memories and learning is taking place amongst other things. Re no one showing a computer screen is harmful, the blue light from devices can keep people awake for longer including when using F.Lux, and the circadian rhythmes are such that it supresses the release of melatonin the sleep hormone which typically starts to rise from around 21:30 peaking around 01:30 before dropping off sharply. This time various depending on where you live in the world and day of the year as its link to sunset times. Melatonin is also 4x more potent as an anti-oxidant than Vitamin C and also helps increase the release of mesenchymal stem cells which aid the repair process carried out when we sleep. So yes studies have shown computer screens, smartphones used late in the evening and at night can cause damage to the body. Its not exclusively blue light which keeps people awake either, red light can also keep people alert, this is why vehicle brake lights are red, red being associated with danger which arouses the mind and body. One of the problems with the human body is it can also function adversely if expected light is missing from the light spectrum of the source. This will become more common place with the use of narrow band light sources like LED's when compared to the sun. The body has evolved over thousands of years in an environment which we are changing rapidly through technology and evolution can not keep up with man made changes.


Isnt it obvious, Keto in the cold months and carbs in the hot months. Eating seasonally is key and you cant chase much or do much exercise in the dead of winter with snow and ice lying around. Its also why the Inuits have a keto diet and can survive the extreme cold.


But healthy keto is lot of veggies no? So winter keto is harder wouldnt it make sense eat carbs in winter?


No, ketogenic diets are mainly fats and protein. Ketosis is the burning of fats which happens when you water only fast. You can live on a diet which is 100% fat, you cant live on a 100% protein diet or a 100% carb diet. Its also why the body stores excess energy in what ever form it was eaten in, as fat. Periodic water only fasting is also the balance to todays modern lifestyles where we have so much food to choose from. Water only fasting, not only starves bacterial colonies in the body, it also helps to starve viruses and parts of the immune system become more effective than during the times when we can eat. The main known risk of water only fasting is diabetic ketoacidosis.

The eight teaspoons of sugar in a can of coke can reduce the hormone Testosterone in young teenage males by 25% within 2hours. The study only concentrated on Testosterone, but it would be interesting to find any studies, if they exist in the public domain, that shows what other effects sugar has on hormone levels, besides insulin and its increased risk of diabetes.


> you cant chase much or do much exercise in the dead of winter with snow and ice lying around.

I take it you don't enjoy snowshoeing or XC skiing? I really enjoy aerobic activities in the cold. In the heat? Not so much...


What if you live in the tropics?
