Why should I not have caffeine after 12 o’clock every day?    

The quarter life of caffeine is 12 hours, so 12 hours after you have your last caffeine, a quarter of that is still buzzing around your brain. 

What are the benefits of cold showers?

Ideally, the research that is most ideal is an ice bath followed by a sauna. But while that’s not mostly practical for all of us, there’s some research from Finland that’s shows there’s some benefits of a 15, 30 or 60 second cold shower because it has a beneficial effects of our immunity from colds and even if you do get sick it reduces the number of days you get sick. What you want to do is shock your body and show it that you can control your recovery afterwards, so it’s important to have the cold shower first then warm yourself up afterwards. It’s almost like a form of inoculation.

Why should I not have too much alcohol particularly within 2 minutes of bedtime?

Timing is really important here, and its binary, which is that even small amounts of alcohol have a disproportionate effect on your sleep. Any consumption, eating or drinking means that your body can’t go into recovery during sleep until you’ve digested or dealt with any toxins (like alcohol) even if you don’t drink alcohol or you eat late, it will still disturb you. 

Why should I not look at my phone during the night?

Any devices that admit blue light, (which mimics natural daylight) there’s a gland called the pineal gland which releases melatonin one hour before we fall asleep and the blue light disrupts that process. There is an app called flux that makes the light on your devices more orange, which is helpful, but it’s also because your brain is buzzing with the latest thing that you’ve read and stops the winding down process. Even checking it for 2 seconds, the blue lights effect on you can be disastrous for this process. There is even evidence that it can increase your cancer risk – which is due to the body not adopting the natural day and night cycles. 

What are the positive impacts of practicing some form of gratitude?

It’s so easy to go through life and not pause and think about what you’ve accomplished and move on to the next thing, and the reason for that is to ensure our survival our brains are geared more to avoid a loss than to seek a reward, we focus on the negatives about twice as much as we focus on the positives. I do a list of 10 things and write them down. Gratitude brings to the front of the mind the more positive, abundant style of thinking and in the research that I’ve done, I’ve found that overtime that list develops and moves more from the external things like friends and family that you are grateful for to more intrinsic capabilities like my resilience my creativity, my adaptability my ability to solve problems. Once you really acknowledge that to yourself you start to feel like ok, if something bad happens to me, I’m more aware of the capabilities I have to deal with that. So, when there’s a crisis, you know you can get through it.
