Biological factors for our purposes include genetics and factors that effect our physiology and biochemistry. For organizing purposes I may distinguish between biological and psychological dimensions but it is important to remember these are not distinct because The mind and body are one.

Neuroscientist Andrew Huberman’s “Big 6” are a useful framework for this:

• Sunlight regulates mood and ultradian & circadian rhythms (cycles of sleep and wakefulness).
• Daily movement and exercise
• Quality nutrition
• Stress management (significant overlap with this one between psychological and biological dimension)
• Healthy relationships
• Sleep health

We should also consider the role of genetics which contributes to happiness.

Happiness is partially determined by genetics (perhaps 30-40%).

A simple, highly credible set of guidelines for nutrition is the “Pegan” diet from Mark Hyman.

Light is an underrated factor in happiness.
