  • has tips for daily lifestyle hacks in every chapter
  • Has information about measuring and health technology 
  • Has insightful health tips for situations that you normally don’t find health tips for (flying, office, nature walks, therapy, evening routines, morning routines, etc)



1. Biohacker’s handbook: Sleep

Chapter in sleep starts with why sleep matters. You will then learn about the importance of sleep, and tools for upgrading sleep. In addition, you learn lifestyle tips on how to prepare for better sleep during the day and what to do just before bed in order to catch the most optimal sleep.

  • These foods contain tyramine which increases the production of noradrenaline and can prevent falling asleep when eaten in the evening: bacon, cheese, chocolate, eggplant, spinach, tomato.
  • To measure and increase your sleep quality and quantity, pay attention to these numbers: the amount of REM, amount of deep sleep, times waking up during the night, daily resting HR, body temperature, HRV, Sleep Onset Latency (time it gets to fall asleep)
  • To optimize sleep, get enough blue light during the day and block blue light during the evenings. Red light in the evening can increase melatonin production


2. Biohacker’s handbook: Nutrition

Chapter in nutrition starts with explaining how nutrition shapes the way you are.

Sneak peek of the content:

  • Fish: Eating fish is important for brain function, mood and immunity.
