Importance of Sleep for Health

Sleeping well can bring numerous health benefits.

The healing power of sleep cannot be overemphasised because even fitness enthusiasts are advised to eat healthy, exercise and have good quality sleep.

However, many factors prevent individuals from enjoying quality sleep. In fact, people today are having much less sleep than they did during the ancient days. Similarly, the quality of sleep has been compromised. Sleep plays a critical role in overall health and well-being. In fact, sleeping and healing have become synonymous. How you feel after waking up largely depends on the quality of sleep you get at night.

Below is why sleeping contributes positively toward overall health.

Helps Avoid Weight Gain

There is a link between quality of sleep and weight. Poor sleep could cause you to become fat.

Studies have shown that those who sleep for shorter hours tend to weigh more than individuals who get enough sleep. In fact, sleep deprivation is a substantial risk factor for obesity. This is because it affects hormones as well as the motivation to get involved in physical activity. Therefore, if losing weight is your goal, then getting adequate sleep is critical.

Improves Alertness and Productivity

Sleep allows the brain to function better, including cognition, productivity, performance, and overall concentration.

Sleep deprivation could significantly affect these factors. Those who fail to get quality sleep are generally lethargic and spend the rest of the day feeling tired and weak. In fact, studies have demonstrated that inadequate sleep could affect individuals in the same way alcohol intoxication does. In contrast, good quality sleep could significantly boost brain function and enhance problem-solving skills. Those who sleep well are also more likely to have improved memory and performance.

Helps Avoid Depression

The healing power of sleep goes beyond typically avoiding irritability.

Consistently getting inadequate sleep could result in depression, but quality sleep could decrease anxiety and improve your mood. If you want emotional stability then you should perhaps take your quality of sleep seriously. Spending long hours on a project and depriving yourself of sleep could quickly lead to anxiety and impatience.

Improves Immune Function

Any slight decrease in the quality of sleep could impair immune function. Studies have demonstrated that sleeping for less than 7 hours could increase the risk of developing a cold. On the other hand, sleeping for 8 hours could boost your immune function and make you less susceptible to cold. Those who frequently get colds need to sleep for 8 hours and eat more garlic to reduce the likeliness of catching a cold.


Sleep and healing are largely inseparable because sleep has been linked to numerous health benefits.

If you want to improve brain function, memory, and immune system, you need at least 7 hours of quality sleep. Sleeping well could also help you avoid stress, anxiety, and depression. If you are having trouble concentrating on your routine activities, then you might be suffering from serious sleep deprivation. It is generally recommended to get between 7-8 hours of sleep to help maintain good health and well-being. Getting inadequate sleep could significantly affect your overall health.
