Understanding Cortisol

Before delving into whether or not strength training increases cortisol, it’s important to understand what cortisol is and its role in the body.

Cortisol is a hormone that is released by the adrenal glands in response to stress. It is commonly known as the “stress hormone” and plays a crucial role in the body’s fight or flight response. Cortisol is responsible for regulating blood sugar levels, controlling inflammation, and managing the body’s response to stress.

While cortisol is essential for overall health and wellbeing, chronically elevated levels of cortisol can have negative effects on the body.

The Negative Effects of High Cortisol Levels

High levels of cortisol can increase the risk of various health problems such as:

  • Weight gain
  • High blood pressure
  • Heart disease
  • Insomnia
  • Anxiety and depression
  • Weakened immune system
  • Cognitive impairment
  • Digestive issues
  • Skin problems

Strength Training and Cortisol

Now that we have a basic understanding of cortisol, let’s explore whether or not strength training increases cortisol levels.

The Acute Response

During strength training, cortisol levels rise acutely. This is a natural and expected response to exercise. In fact, many experts believe that the acute cortisol response to strength training is essential for the body’s adaptive response to exercise.

When you lift weights, your body perceives this as a stressor and releases cortisol in response. This cortisol response helps the body mobilize energy stores and repair damaged tissues. As a result, strength training can be an effective way to improve overall health and fitness.

The Chronic Response

While the acute cortisol response to strength training is beneficial, chronically elevated cortisol levels can have negative effects on the body. One study found that overtraining, which can lead to chronically elevated cortisol levels, can lead to decreased immune function, muscle wasting, and increased risk of injury.

However, research has also shown that strength training can actually reduce chronic cortisol levels. One study found that after 12 weeks of strength training, cortisol levels were significantly lower in the participants who exercised compared to those who did not.

The Bottom Line

So, does strength training increase cortisol levels? The answer is yes, but only acutely. In the long term, strength training can decrease chronic cortisol levels and provide a multitude of health benefits.

It’s important to remember that cortisol is not inherently bad. It’s essential for the body’s stress response and plays a crucial role in overall health and wellbeing. While chronically elevated cortisol levels can have negative effects, proper exercise and stress management can help keep cortisol levels in check.

Tips for Managing Cortisol Levels

If you’re concerned about your cortisol levels, there are several things you can do to help manage them.

Exercise Regularly

As we’ve discussed, strength training can be an effective way to manage cortisol levels. However, any form of exercise can be beneficial for managing stress and cortisol levels. Aim for at least 30 minutes of moderate exercise per day.

Practice Stress Management

Stress is one of the biggest contributors to chronically elevated cortisol levels. Practicing stress management techniques such as meditation, yoga, or deep breathing can help keep cortisol levels in check.

Get Enough Sleep

Sleep deprivation can lead to increased cortisol levels. Aim for at least 7-8 hours of sleep per night to help keep cortisol levels in balance.

Eat a Balanced Diet

Eating a diet rich in whole, nutrient-dense foods can help keep cortisol levels in check. Aim for a diet that includes plenty of fruits, vegetables, lean protein, and healthy fats.

Limit Caffeine and Alcohol Intake

Both caffeine and alcohol can contribute to chronically elevated cortisol levels. Limit your intake of these substances to help keep cortisol levels in balance.

Conclusion

In conclusion, while strength training does increase cortisol levels acutely, it can actually decrease chronic cortisol levels in the long term. Proper exercise, stress management, and lifestyle habits can help keep cortisol levels in check and provide a multitude of health benefits. So, don’t be afraid to hit the gym and lift some weights!
