Amidst all the content I consume every week, through this weekly series of ‘My Weekly Learnings’, sharing highlights of content pieces that caught my eye and provided more value than I could imagine.
(P.S. Every Sunday, I share a list of what to read, listen to, and watch, in my weekly series, The Last 7 Days. You can check out the editions here).
1. What is an amygdala hijack?
Amygdala hijack is an emotional response to stress, often thought of as losing control of one’s emotions.
An example of this is where you are talking to a friend and they do not appear to be listening to you, ignore what you say, or maybe talk over the top of you.
This kind of interaction can make you ‘snap’. You may suddenly have an outburst such as shouting at them for not listening. Afterwards, you may realize that you overreacted and that the way you acted was unnecessary and you may say to yourself ‘what was I thinking?’.
You may not have been thinking at all as what actually happened is that your amygdala hijacked you.
Amygdala hijack refers to the situations where the amygdala overrides control of a person’s ability to respond rationally to a perceived threat – the logical brain gets impaired due to emotional outbursts caused by the amygdala.

2. The process of learning and remembering things often feels hard and indeed can evoke agitation. Most people don’t realize it, but agitation is the entry point to learning. Literally, the adrenaline that causes agitation signals the nervous system that it should be ready to change. Without it the nervous system is not as primed for change— the process we call neuroplasticity.
Once you understand this, you will more likely embrace (as opposed to avoiding) agitation. Also, after a period of challenging focus and learning, there is an associated increase in feel-good molecules such as dopamine (and to a lesser extent, serotonin).
The takeaway: learning is a process that starts with focus, alertness, and agitation, …and the process is consolidated during sleep and non-sleep deep rest (NSDR).
We all have the capacity for neuroplasticity. Don’t hesitate to lean into it as a process. Recognise the agitation as part of that process. The feel-good part arrives at the end, or days later when, as if suddenly, you have acquired new abilities. [Dr Andrew D Huberman]
3. Movement is literally an expression of the way in which we think and feel. The way you move affects the way you feel, and the way you feel is inseparably tied to the expression of your internal chemistry.
A fascinating study conducted by researchers at Ohio State University showed how posture during communication not only informs the way others perceive you but may even shape your own self-belief.
Researchers asked the participants to list three positive and three negative traits they possess that would impact their professional performance at a future job. Half of the participants were asked to write these traits while they were in a hunched-over position, while the other half were asked to assume an upright posture during the process.
The results were striking. Their posture not only impacted whether or not they identified with the positive things they were asked to write about themselves but also affected a participant’s belief in the statements, positive or negative. [Neurohacker]
4. Lack of sleep can create an imbalance in the body that increases ghrelin levels and lowers leptin levels. This can cause you to feel hungrier during the day. This imbalance caused by sleep deprivation may lead to a higher calorie intake during the day. [Source: Sleep Foundation]
5. The greatest threat to results is impatience.
If you let it, a tiny daily advantage will compound into a massive generational one.
A lack of patience changes the outcome. [Shane Parrish]
