Understanding Jet Lag: Causes, Effects, and Strategies for Overcoming It
TLDR Jet lag, also known as desynchronosis, occurs when our bodies get out of sync with the time zone we are in, leading to cognitive and health problems such as fatigue, irritability, and even shorter lifespans in older individuals. It can impair cognitive function, hinder brain function and neuron growth, increase the risk of heart disease and diabetes, disrupt natural rhythms and hormone production, and cause sleepiness and sleep pressure. To combat jet lag, gradually adjust your circadian rhythm, regulate exposure to light, avoid certain foods and substances, and consider using devices like the Valky to reduce stress and anxiety.

Jet lag, also known as desynchronosis, occurs when our bodies get out of sync with the time zone we are in, leading to cognitive and health problems such as fatigue, irritability, and even shorter lifespans in older individuals.

Jet lag can impair cognitive function and decision-making abilities, hinder brain function and neuron growth, increase the risk of heart disease and diabetes, disrupt the body's natural rhythms and hormone production, and cause sleepiness and sleep pressure.
14:10
Jet lag disrupts biological functions, releases stress hormones, drives up blood pressure, causes inflammation, messes up appetite, and can lead to unusual behavior such as eating in the middle of the night.
18:11
When you wake up early, you may notice that you're more hungry than usual, and eating certain foods like bananas or red meat can make you even more hungry, possibly due to the disruption of your biological functions caused by jet lag.
22:32
Jet lag is difficult to overcome because our body's circadian rhythm is slightly longer than 24 hours, causing us to be ready for sleep later and later each day, and waking up during our body's minimum temperature, or T-min, can make jet lag worse.
27:00
Gradually adjust your circadian rhythm by going to bed an hour earlier each day before your trip and using a light box in the morning to offset jet lag.
31:14
Regulate your exposure to light by wearing sunglasses in the morning, using a light box at bedtime, and adjusting your exposure to light based on the direction of travel; avoid big meals, spicy food, alcohol, and caffeine; consider using a device called the Valky that emits light through the ear canal to reduce stress, seasonal depression, and anxiety.
