Over the last two weeks we have looked at some of the underlying reasons that can contribute to feeling tired despite us getting enough sleep. These include:
- Stress or anxiety
- Hormonal imbalances and underlying health conditions
- Nutritional deficiencies
- Lack of physical activity
- Other lifestyle factors
We have covered stress and anxiety, hormonal balances and underlying health conditions as well as nutritional deficiencies in the last two podcasts. Today we will look at lack of physical activity and other lifestyle factors.
Lack of physical activity
Regular exercise boosts our energy levels so it goes without saying that too little activity can make us feel more tired and here’s why:
Physical activity helps stimulate the production of our mitochondria, which are the “powerhouses” of our cells that produce energy. Regular exercise increases the number and efficiency of mitochondria, which boosts our energy levels. Without physical activity, mitochondrial function may decrease, leading to lower energy production, which can make us feel tired and lethargic.
Exercise improves our circulation, which delivers more oxygen and nutrients to our muscles and organs. When we’re inactive, our blood circulation is less efficient, which can lead to sluggishness and fatigue. Poor circulation means less oxygen gets to our tissues, which reduces our energy and makes us feel more tired.
Lack of movement causes muscle deconditioning, which means our muscles weaken and lose endurance over time, making even small tasks exhausting. Weaker muscles require more effort to perform daily tasks, leading to a quicker onset of fatigue and making activities feel more strenuous.
Lack of exercise often leads to weight gain because we burn fewer calories than we consume. Carrying extra weight can make everyday activities more tiring and increase the physical demand on our bodies. Excess weight can put strain on muscles, joints, and the cardiovascular system, making us feel fatigued more easily.
Physical activity triggers the release of endorphins, which are brain chemicals that promote a sense of well-being and increase our energy levels. Without regular exercise, our bodies produce fewer endorphins, which can lead to lower energy and mood swings, leaving us feeling mentally drained.
Physical activity stimulates our brains and improves our cognitive function, focus, and mental clarity. Without physical exercise, our brains can feel foggy or sluggish, contributing to mental fatigue and making it harder to focus on tasks.
Other lifestyle factors
Irregular sleep patterns, overuse of caffeine, or staying in dark, enclosed spaces for long periods can also affect our energy levels.
