Questions: All of the following can help improve immune function as people age EXCEPT consuming more calories steroid drugs sleeping more exercise

The answer is the first one: consuming more calories.

Explanation for each option:

1. Consuming more calories: This is incorrect as a method to improve immune function. While adequate nutrition is important for maintaining a healthy immune system, simply consuming more calories does not necessarily enhance immune function. In fact, excessive calorie intake can lead to obesity, which is associated with impaired immune function.

2. Steroid drugs: This is incorrect as a method to improve immune function. Steroid drugs, such as corticosteroids, are known to suppress the immune system. They are often used to reduce inflammation and treat autoimmune conditions, but they can weaken the immune response, making this option unsuitable for improving immune function.

3. Sleeping more: This is correct as a method to improve immune function. Adequate sleep is crucial for maintaining a healthy immune system. During sleep, the body produces cytokines, which are important for fighting infections and inflammation. Therefore, getting enough sleep can help enhance immune function.

4. Exercise: This is correct as a method to improve immune function. Regular physical activity is known to boost the immune system by promoting good circulation, which allows immune cells to move through the body more effectively. Exercise can also help reduce inflammation and support overall health.

In summary, consuming more calories is the option that does not help improve immune function as people age.
