AI Overview

There are many reasons why people tire more easily as they age, including:

Cellular changes

Aging can cause cells to change, which can lead to muscles losing mass and strength, and becoming less flexible. This makes it harder to do strenuous activities.

Metabolism decline

As people age, their bodies become less efficient at metabolizing nutrients, which can lead to lower energy levels.

Nutritional deficiencies

As people age, they may lose muscle mass and eat less, which can lead to undernutrition.

Undernutrition can cause fatigue and muscle wasting.

Restricted blood flow

Fatty deposits can build up in blood vessel walls, making them thicker and stiffer. This can reduce blood flow and make the heart less able to pump oxygen-rich blood to cells.

Dehydration

People can become dehydrated if they don't drink enough water to replace what they lose through urine, sweat, stool, and breathing.

Some ways to help with fatigue include:

Exercise

Regular exercise can help maintain cardiovascular fitness and a healthy weight.

Cognitive behavioral therapy

This can help people learn to adjust their expectations and address intrusive thoughts.

Occupational therapy

Occupational therapists can help people learn how to manage and decrease fatigue.

Setting goals

Setting small, achievable goals can help people feel energized.
