My father is over 60 years old and now retired due to problems with his eyesight (amblyopia, glaucoma, cataract). Other than that he's always been fairly healthy and active. However I am concerned because since the retirement he tends to just lay in bed all day (we live in the same apartment and based on my observations I'd guess he spends at least 18 hours in bed on average).

I want to find out more about the situation in question. What are the possible effects of this? I'm having a hard time finding respectable sources because "bedridden" does not seem to be a correct term here.

    This is outside the scope for questions on this site as it has nothing to do with physical fitness relating to exercise and instead is just asking for medical advice/information. Commented Feb 25, 2014 at 10:32
  • Contact your father's personal doctor, and make personal arrangement. He is the one who is aware of his health and any past health treatment, and should be able to discuss with you on this topic. Second, based on father's doctor recommendation contact a specialist within your living area.

    I strongly disagree. Inactivity has an inverse relationship with physical fitness. Health is directly related to fitness. Commented Feb 25, 2014 at 17:22
  • Being inactive is not good for you, e.g. see economist.com/news/science-and-technology/…

  • I also lie in bed all day and find it difficult to stay up. It's not apathy , it's due to some medication I am given. Doctors should not prescribe highly sedative drugs.

You are asking about the effects of a sedentary lifestyle. This is certainly related to physical fitness, or rather a lack thereof, contrary to what some of my fellow members here feel.

There are a number of physiological adaptations that will result from too much inactivity.

I like to say that our bodies are built to be as lazy as possible. Efficiency is the driving force behind survival-if you're not going to use muscle, why spend energy maintaining it?

The effects of inactivity are wide and very detrimental to health.

Your father is going to experience the following:

  • Decreased Muscle Mass
  • Decreased Immune System function
  • Decreased Bone Density
  • Decreased Oxygen Consumption (VO2)

Now keep in mind that all the said functions are intertwined with each other-the effects experienced from inactivity go far deeper than most people realize. There are a myriad number of effects that I'm not listing, both because I don't know them all (no one does), and that the human body's system is so well tied together that it's hard to pinpoint any one thing.

The real killer is that last one. Because your father isn't placing a load on his systems to sustain life, his ability to consume oxygen is going to drop. This is an adaptation to his inactivity. Why would the body want to spend more energy maintaining what isn't used?

When the time comes to move and labor intensely, it's going to be that much harder for his heart and lungs to adapt. This is where the risk lies in contracting any sort of cardiac condition (especially heart attack).

This is also why so many elderly die when shoveling their driveways. By decreasing his muscle mass, he's also decreasing his ability to move, and therefore increasing his risk for breaking bones, because there's not enough muscle to counteract imbalances. This doesn't include decreased sensitivity to insulin (prediabetes or diabetes).

This also is why many people die soon after breaking a hip-they're too inactive, so they have no muscle, and in turn they fall and break a hip. They're now bedridden. Because their VO2 is so low and decreases even further, their heart eventually fails.

Your (and your father's) body was not designed to take it easy all the time. It was designed to work-and work efficiently. Our bodies were designed to strive towards being lazy, but not actually be lazy.

If he wants to live longer, he has to move. That's the bottom line. He's going to die if he doesn't.
