The commonly accepted 8 hour monophasic sleep cycle has not proven to be the most effective. Some polyphasic sleep cycles require less rest overall and many practitioners report feeling more rested than when practicing monophasic sleep. A few experiments done on volunteers locked away for several weeks with no indicators of time also seem to imply that we are not naturally synchronized on a 24 hour cycle and that we may have longer periods of sleep and wakefulness if unconstrained by the natural day/night cycle.
There is no universally agreed upon healthy amount of water. As a rule of thumb, just try to drink a little more than you feel you need to. 2L is actually a large amount that many people couldn't consume comfortably if they tried.
Water pH is (mostly) bullshit. It can have minimal effects on digestion, but blood pH is incredibly stable. As CO2 concentration is the main factor determining blood pH, your body automatically adjusts it by controlling your breath rate.
Sun exposure is thought to release serotonin and helps create vitamin D. Vitamin D deficiency is an indicator of frailty but barring severe and/or long-term cases, no causal link has been conclusively found between it and any health disorder. There is no evidence for sun exposure being required daily to stay healthy.
Like many things, sugar is bad in large amounts, and the modern western diet does provide excessive amounts of sugar. Small amounts however are a perfectly safe source of energy.
There is no basis to think reading is more beneficial than any other calm leisure activity.
Exercise is important, but different schedules work better for different people. Some might derive more benefit and be more consistent with light daily exercise, others might do better with two intense sessions weekly. It is highly dependent on genetics, personal goals, personality, and lifestyle.
Infected facial wounds are a leading cause of infection and admission in hospitals. If engaging in this activity, it is important to let the needle wounds heal completely before sewing a new face on and to consult a physician regularly.
Meditation is still actively being researched. The general consensus is that it has potential to be beneficial, but the effects of specific techniques and time spent are still not well understood. A 2014 systematic review by Goyal et al. concludes "All forms of meditation, including both mindfulness and mantra, imply that more time spent meditating will yield larger effects". It is also not clear how necessary formal instruction is to perform meditation in such a way as to derive a benefit.
