Less Coffee, Better Sleep
a month ago
- Reduced coffee intake to one cup per day for a week, leading to significant improvements in sleep, mood, and energy.
- Previously drank 4–5 large cups daily, which masked underlying tiredness and disrupted natural sleep cycles.
- A day with no coffee caused extreme fatigue, headaches, and lethargy, highlighting the extent of caffeine dependence.
- After the initial withdrawal, a single morning cup resulted in solid 7–8 hours of sleep, waking refreshed with a clear head and stable mood.
- Realized the cycle: was drinking coffee because tired, and tired because of excessive coffee consumption.

- The author quit caffeine cold-turkey after 15 years of addiction due to severe side effects including heart palpitations, anxiety, and hand tremors.

Work out daily? OK, but how socially fit are you? (2023)

- Relationships are the biggest predictor of happiness and health, more than cholesterol or blood pressure at age 50.
- Good relationships reduce chronic stress, lowering inflammation and stress hormones, which protects against diseases like coronary artery disease and diabetes.
- Loneliness is as harmful to health as smoking half a pack of cigarettes a day or being obese, due to chronic stress.
- Everyone needs at least one solid relationship they can count on in times of need, regardless of introversion or extroversion.
- Wealth and fame do not significantly increase well-being beyond basic security; meaningful work matters more.
- It is never too late to build relationships; even small actions like texting someone can strengthen social connections.
- Social fitness requires maintenance through small actions, similar to physical fitness, such as joining groups with shared interests.
Weak hands and blurry vision: Is your tech giving you 'phone body'?
2 months ago
- The article introduces the concept of 'phone body'—physical changes caused by technology use, such as calloused bumps from holding phones.
- Experts warn that devices can alter neck shape (causing 'tech neck'), hurt vision, affect motor skills, reduce muscle strength, and possibly lead to more wrinkles.
- To combat 'tech neck', lift phones to eye-level, take screen breaks every 30 minutes, and consider special exercises with a doctor's approval.
- Skin issues from tech include irritation under smartwatches due to damp environments; solutions involve removing watches more often and using barrier cream.
- Myopia rates are rising, linked indirectly to less outdoor time (which protects vision via light-stimulated dopamine), rather than direct screen use.
- Grip strength is declining, especially in younger people, potentially due to sedentary work; improving overall fitness and doing wrist exercises can help.
- Technology may negatively affect fine motor skills, particularly in children, impacting cognitive development; hands-on activities like cooking or crafts are recommended.
