Getting enough sleep is one of the best things you can do to boost your immune system and protect yourself from infection. Aim for 7-8 hours of sleep per night.
Inflammation
Inflammation is a natural response to injury or infection. It helps to protect the body by sending white blood cells to the affected area to fight off the infection. However, chronic inflammation can damage the body’s tissues and organs, and has been linked to a number of diseases, including heart disease, stroke, cancer, and diabetes.
Sleep helps to reduce inflammation by:
- Reducing the production of inflammatory cytokines: Cytokines are proteins that promote inflammation. Sleep helps to reduce the production of these cytokines, which can help to reduce inflammation throughout the body.
- Increasing the production of anti-inflammatory cytokines: Sleep also helps to increase the production of anti-inflammatory cytokines, which help to reduce inflammation.
- Improving the function of the immune system: Sleep helps to improve the function of the immune system, which helps to fight off infection and reduce inflammation.
Getting enough sleep is one of the best things you can do to reduce inflammation and improve your overall health. Aim for 7-8 hours of sleep per night.
Heart health
Sleep is essential for heart health. When we sleep, our bodies produce hormones that help to lower our blood pressure and cholesterol levels. These hormones also help to reduce inflammation and improve the function of our blood vessels.
Getting enough sleep can help to reduce our risk of heart disease by:
- Lowering our blood pressure
- Lowering our cholesterol levels
- Reducing inflammation
- Improving the function of our blood vessels
People who don’t get enough sleep are more likely to develop heart disease. In fact, a study published in the journal Circulation found that people who slept less than 6 hours per night were more than twice as likely to develop heart disease than people who slept 7-8 hours per night.
Getting enough sleep is one of the best things you can do for your heart health. Aim for 7-8 hours of sleep per night.
| Benefit | How it helps |
|---|---|
| Lower blood pressure | Sleep helps to lower our blood pressure by reducing the production of stress hormones and increasing the production of relaxation hormones. |

| Reduce inflammation | Sleep helps to reduce inflammation by reducing the production of inflammatory cytokines. |
| Improve the function of our blood vessels | Sleep helps to improve the function of our blood vessels by increasing the production of nitric oxide, which helps to relax blood vessels and improve blood flow. |
Obesity
Sleep is essential for maintaining a healthy weight. When we sleep, our bodies produce hormones that help to regulate our appetite and metabolism. These hormones include leptin and ghrelin. Leptin is a hormone that signals the brain that we are full, while ghrelin is a hormone that signals the brain that we are hungry.
When we don’t get enough sleep, our bodies produce less leptin and more ghrelin. This can lead to increased appetite and cravings for unhealthy foods. In addition, sleep deprivation can also lead to changes in our metabolism, making it more difficult to burn calories.
Getting enough sleep can help to regulate our hormones and maintain a healthy weight. Aim for 7-8 hours of sleep per night.
| Hormone | Function | Effect of sleep deprivation |
|---|---|---|
| Leptin | Signals the brain that we are full | Decreased production |
| Ghrelin | Signals the brain that we are hungry | Increased production |
Real-life examples
- A study published in the journal Obesity found that people who slept less than 6 hours per night were more likely to be obese than people who slept 7-8 hours per night.
- Another study, published in the journal Diabetes Care, found that people who slept less than 5 hours per night had higher levels of ghrelin and lower levels of leptin than people who slept 7-8 hours per night.
Practical significance
Getting enough sleep is one of the best things you can do to maintain a healthy weight. Aim for 7-8 hours of sleep per night. If you are struggling to get enough sleep, talk to your doctor about ways to improve your sleep habits.
Mood
Sleep is essential for our mental health. When we don’t get enough sleep, we are more likely to experience mood swings, irritability, and difficulty concentrating. We are also more likely to develop mental health disorders such as depression and anxiety.
- Improved mood: Sleep helps to improve our mood by regulating the production of neurotransmitters, which are chemicals that transmit signals between nerve cells. Neurotransmitters such as serotonin and dopamine are involved in mood regulation, and sleep deprivation can lead to decreased levels of these neurotransmitters.
- Reduced risk of depression: Sleep deprivation has been linked to an increased risk of depression. In fact, a study published in the journal JAMA Psychiatry found that people who slept less than 6 hours per night were more than twice as likely to develop depression than people who slept 7-8 hours per night.
Getting enough sleep is one of the best things you can do for your mental health. Aim for 7-8 hours of sleep per night. If you are struggling to get enough sleep, talk to your doctor about ways to improve your sleep habits.
Energy levels
Sleep is essential for our physical and mental health. When we don’t get enough sleep, we are more likely to feel tired, fatigued, and sluggish. We may also have difficulty concentrating and making decisions.
There are a number of reasons why sleep is so important for our energy levels. First, sleep helps to restore our body’s energy stores. When we sleep, our bodies produce hormones that help to repair our cells and tissues. These hormones also help to regulate our metabolism, which is the process by which our bodies convert food into energy.
Second, sleep helps to improve our cognitive function. When we sleep, our brains consolidate our memories and improve our ability to learn and problem-solve. This is why we often feel more clear-headed and alert after a good night’s sleep.
