What Does Instinctively Keep Us Alive?

Humans are complex beings, and it can be challenging to decipher why we do what we do. However, one of the most basic instincts we possess as humans is the instinct to survive. This instinct is hard-wired into our brains, and it’s what drives us to seek food, shelter, and safety.

In this article, we’ll explore the various factors that instinctively keep us alive. From physical survival mechanisms to our emotional responses, we’ll take a deep dive into the primal instincts that drive us to survive.

The Fight or Flight Response

One of the most well-known survival instincts is the fight or flight response. This response is triggered in situations where the brain perceives a threat or danger. When the fight or flight response is activated, the body produces adrenaline, which prepares the body to either fight the threat or flee from it.

This instinct evolved over thousands of years and was essential to the survival of our ancestors. In situations where our ancestors encountered a predator, the fight or flight response would give them the necessary energy to either fight off the predator or run away from it.

The Freeze Response

Another lesser-known survival instinct is the freeze response. This response is triggered when the brain perceives a threat but believes that fighting or fleeing would be unsuccessful. In these situations, the body will “freeze,” and the individual will become still, hoping to avoid detection by the predator or threat.

The freeze response is often seen in animals, such as rabbits, who freeze when they perceive a predator nearby. This instinct can sometimes be beneficial to humans as well, such as when a person is lost in the wilderness and needs to stay still to avoid detection by predators.

The Importance of Sleep

Sleep is another essential aspect of human survival. The body requires rest to repair and regenerate cells, which is crucial for maintaining good health. Lack of sleep can lead to a weakened immune system, which can make an individual more susceptible to illness and disease.

Additionally, sleep is essential for the brain to consolidate memories and learn new information. Sleep deprivation can lead to memory loss, difficulty concentrating, and impaired cognitive function.

While the exact reason why humans need sleep is not entirely understood, it’s clear that lack of sleep can have severe consequences for overall health and well-being.

The Circadian Rhythm

The circadian rhythm is the body’s natural internal clock, which regulates various physiological processes, including sleep. The circadian rhythm is influenced by external factors such as light and dark and can be disrupted by factors such as shift work or traveling across time zones.

When the circadian rhythm is disrupted, it can lead to sleep disturbances, fatigue, and other health issues. Therefore, ensuring that we maintain consistent sleep patterns and avoid disrupting our natural internal clock is essential for good health.

The Importance of Social Connection

Humans are social creatures, and social connection is another essential aspect of human survival. Research has shown that social isolation can have severe consequences for physical and mental health.

Individuals who are socially isolated are more likely to experience depression, anxiety, and other mental health conditions. Additionally, social isolation can lead to increased inflammation in the body, which is linked to various health issues, including heart disease and cancer.

The Role of Oxytocin

Oxytocin is often referred to as the “love hormone” and is involved in social bonding, trust, and empathy. When individuals engage in social bonding activities, such as hugging, kissing, or even sharing a meal, the brain releases oxytocin.

Oxytocin has been shown to have various health benefits, including reducing stress and anxiety levels and improving immune function. Therefore, maintaining social connections is not only essential for our mental well-being but also for our physical health.

The Importance of Nutrition

Nutrition is another critical aspect of human survival. The body requires a variety of nutrients to function correctly, and deficiencies in these nutrients can lead to a variety of health issues.

Additionally, consuming a healthy and balanced diet can help prevent chronic diseases such as heart disease, diabetes, and cancer.

The Role of Macronutrients and Micronutrients

Macronutrients, such as proteins, carbohydrates, and fats, are essential for providing the body with energy and maintaining proper cellular function. Micronutrients, such as vitamins and minerals, are essential for various physiological processes, including immune function and blood clotting.

Therefore, ensuring that we consume a healthy and balanced diet that provides an adequate amount of both macronutrients and micronutrients is crucial for maintaining good health.

The Importance of Exercise

Exercise is another crucial aspect of human survival. Regular exercise can help maintain a healthy weight, reduce the risk of chronic diseases, and improve overall cardiovascular health.

Additionally, exercise can help improve cognitive function, reduce stress levels, and improve mental health.

The Benefits of Strength Training and Cardiovascular Exercise

Strength training and cardiovascular exercise are two essential types of exercise that provide various health benefits. Strength training can help build muscle mass, which can increase metabolism and reduce the risk of osteoporosis.

Cardiovascular exercise, such as running or cycling, can improve cardiovascular health and reduce the risk of conditions such as heart disease and stroke.

Conclusion

Survival is a complex instinct, involving multiple factors that influence our overall health and well-being. By understanding the various aspects of human survival, we can take steps to ensure that we maintain good health and live a long and fulfilling life.
