This thread is peak HN. People even suggesting amphetamines. You could try what the rest of the world without a burnout-inducing work culture does: take a 15/30 min nap.

Meta commenting really isn't interesting to read. Also, more people have suggested naps than amphetamines in this thread. Naps aren't a great solution anyway.

1 - after-lunch fatigue is often caused by an interruption in one’s ultradian rhythm, often induced by early consumption of caffeine. Wait a full ultradian cycle (90 minutes) after waking before caffeine consumption in the morning. Even for longtime early morning coffee drinkers, it’s actually pretty easy to break the habit and delay caffeine intake. (Early morning concentration does not suffer.) 2 - get early mornin…

Andrew Huberman, is this you?

Valuable advice.

I think this can provide you some information: https://en.wikipedia.org/wiki/Postprandial_somnolence

From the article: Counteraction A 2015 study, reported in the journal Ergonomics, showed that, for twenty healthy subjects, exposure to blue-enriched light during the post-lunch dip period significantly reduced the EEG alpha activity, and increased task performance.[29]

> take a real rest after midday meals. Go for a walk. Do nothing. Hangout with friends. Read. Rests must be real (no social media) to be effective. Honestly, going for a walk or reading is more energy-demanding that social media. People default to social media because it provides the most pleasure for the least amount of energy expended.

It’s not about energy-demand – it’s about motivation circuitry (dominantly dopamine). Humans have a lot of “energy” to do a lot of different things irrespective of midday meals. The issue is motivation, flow states, feelings of reward, joy, cognition.

On this note, social media is a terrible rest as it makes the brain pump with endorphins, making it immediately more difficult to find motivation for anything with delayed dopaminergic effect.

I take 10mg of mixed amphetamine salts or similar, as prescribed. Works great for my attention and focus! Take drugs to solve your problems, kids.

I assume cocaine works as well?

So far none of my doctors have proposed such treatment. It’s generally short-acting; probably not a good move for a therapeutic medication.

Or just eat a smaller, healthier lunch.

Also a lower GI lunch. To me, a lunch comprised of mostly protein and fat pretty much nullifies the slump.

Walking for 15-20min after lunch can also help.

Even better, fast until later in the afternoon.

Earlier quoted context omitted.

Or you could just exercise

At lunch? I'd love to, but like most people working in offices, I imagine this advise doesn't suit their schedules.

A few sets of pushups or a jog on break time is usually enough

What works for me is to eat less at lunch.

How? By having a big breakfast. By the time lunch comes I am not starving, and it is easier to have a moderate lunch. This makes it easy not to be drowsy.

Having a big breakfast has also the advantage that it is a great motivator to get up in the morning :)
