The Danger of Unhealthy Biohacking

Teemu warns that many people misuse biohacking by layering stimulants like nootropics on top of poor lifestyles, such as chronic sleep deprivation. This accelerates burnout rather than creating sustainable performance.

Many biohackers are neurotic and unhealthy in their approach.
Using nootropics to compensate for lack of sleep is dangerous.
Pushing performance further without fixing root causes leads to faster burnout.
Increased heart rate from stimulants may accelerate aging.

“They're basically juicing themselves faster.”

Alcohol Doesn't Help You Sleep — It Sedates You

Teemu clarifies that alcohol suppresses deep sleep despite making people feel drowsy. It increases GABA, which relaxes the brain but disrupts restorative sleep cycles.

Alcohol sedates but doesn’t improve sleep quality.
It inhibits deep sleep, crucial for brain detoxification.
Even two glasses can reduce deep sleep significantly.
It’s a common misconception among biohackers.

“You're not sleeping, you're sedating yourself.”

It's Not Time Management — It's Attention Management

Teemu argues that most people don’t have a time problem but an attention problem. Nootropics and caffeine can worsen focus if the underlying issue is poor attention control.

People mistake attention issues for time issues.
Nootropics can make you more distractible if overstimulated.
Deep work requires calm, not stimulation.
L-theanine and lemon balm help more than caffeine for focus.

“You have a limited amount of attention. That's what you need to manage.”

Why Biohacking Isn't Just About Performance

Teemu Arina explains that true biohacking goes beyond performance optimization and is more about improving one's relationship with their environment. It includes self-realization, self-expression, and gaining perspective through practices like tracking sleep or journaling.

Biohacking is not just about productivity but also about well-being and self-reflection.
Tracking behaviors like sleep or steps changes how you relate to them.
The act of measuring brings awareness and shifts behavior.
It’s a modern path to enlightenment using tools and ancient wisdom.

“It is a modern approach to enlightenment, in a way.”

Bilberry vs Blueberry: The Hardcore Superfood

Teemu compares bilberries to cultivated blueberries, explaining that bilberries are wild, more nutrient-dense, and contain anthocyanins throughout the fruit rather than just in the skin.

Bilberries are the wild, more potent version of blueberries.
Anthocyanins are distributed throughout the entire bilberry.
Cultivated blueberries are bred for size and sugar, not nutrition.
Bilberries offer stronger antioxidant and eye health benefits.

“Bilberry is a hardcore blueberry.”

Sauna and Ice Swimming: Heat Shock Proteins and Recovery

Teemu explains that heat and cold exposure boost heat shock proteins, improve cardiovascular health, immunity, and cellular repair. These stressors activate longevity pathways like FoxO3.

Heat shock proteins are triggered by both heat and cold.
They help clean out cellular waste and support longevity.
Sauna once a week reduces cardiovascular disease risk.
Ice swimming improves nervous system resilience.

“Heat shock proteins will clean out intracellular waste.”

The Spirit of the Finnish Sauna: Löyly

Teemu describes the traditional Finnish smoke sauna, where heat retained in stones creates 'löyly'—the spirit of the sauna—when water is thrown on the rocks. This ritual combines fire, water, air, and earth for a holistic experience.

Smoke saunas are heated for 6–12 hours and stay hot for 48 hours.
Löyly refers to the steam and spiritual essence of the sauna.
Herbs hung in the ceiling release essential oils into the air.
The experience is deeply cultural and sensory, not just physical.

“Löyly is the spirit of the sauna.”

Juggling Trains Both Sides of Your Brain

Teemu shares how juggling improved his coordination and mental clarity by strengthening connections in the corpus callosum, the bridge between brain hemispheres.

Juggling enhances coordination between left and right brain.
It increases neural connections in the corpus callosum.
Activities like dance, violin, or slacklining have similar effects.
Contrary to myth, both brain hemispheres are used in all thinking.

“The better the coordination between both sides of the brain, the better you are on both creative and logical thinking.”

Stinging Nettle: A Painful but Powerful Biohack

Teemu shares that stinging nettle is used in Finland both as a therapeutic tool—beating it on the skin to increase blood flow—and as a highly nutritious edible plant.

Beating with stinging nettle increases circulation and relieves pain.
It's traditionally used for kidney issues and inflammation.
It's one of the most micronutrient-dense plants available.
Can be eaten safely when cooked.

“It might hurt for a while, but it's good for you.”

Optimize What You Do Most Often

Teemu suggests focusing on daily habits like sitting, sleeping, and drinking coffee. Small improvements in high-frequency behaviors yield the greatest long-term benefits.

Focus on routines repeated daily: sitting, sleeping, hydration.
Invest in quality chairs, beds, and desks.
Movement breaks improve lymphatic flow.
The 20-20-20 rule helps eye strain and posture.

“Look at the things you do repeatedly. Optimize those.”
