Biohacker’s Handbook is a scientific guide to health optimization and biohacking. It has quickly become the number one manual for learning the basics of biohacking and it has been translated into four different languages and distributed to over 60 countries.

There is a shift in healthcare from hospitals to homes. Measuring health and assessing lifestyle changes is not anymore exclusive to doctors. Instead, modern advances in health technology and shared knowledge brings healthcare to our homes and daily life. We are equipped with various ways of deeply understand, track, and optimize the way our lifestyles from sleep to nutrition affect our hormones, mental balance, and energy levels. This also shifts the healthcare model from treating illness to preventing them.

Biohacker’s Handbook is for those who want to manage their own health and prevent disease before they arise (being proactive instead of reactive). It is also for those who want to improve their productivity, energy levels, and mood. The easy-to-digest manual is a collection of tips and tools for healthy sleep, nutrition, exercise, and work habits based on recent scientific discoveries.

Even though it is a science-based human manual, it is not a biology book (although you will learn a lot about human biology by reading it). However, mainly it is a manual for healthy living. With its practicality, great illustrations and design, and detailed, science-based facts it becomes your personal health guide that helps you to take control of all aspects of your health.

  • 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.

  • 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 (the 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

These fish contains high amounts of mercury and thus should be consumed in moderation: swordfish, tuna, and pike.
