Understanding the Relationship Between Sleep and Chronic Disease
Sleep is increasingly seen as a key factor in the prevention of chronic diseases such as heart disease, stroke, diabetes, and depression. A growing body of evidence suggests that lack of adequate sleep increases a person’s risk of developing a chronic illness. It is important to understand the relationship between sleep and risk factors for chronic disease and how we can make sure we get enough sleep to stay healthy.
How Does Sleep Impact Our Health?
Sleep is essential for our physical and mental health. Chronic lack of sleep, usually defined as having fewer than seven to eight hours of sleep, contributes to an increased risk for health problems. This includes:
- Heart health: Not getting enough sleep puts us at risk for developing cardiovascular disease. This is because lack of sleep raises our blood pressure, heart rate, and body temperature, all of which can contribute to cardiovascular disease.
- Diabetes: Studies have found that lack of sleep is linked to an increased risk for type 2 diabetes.
- Mental health: Insufficient sleep can elevate stress hormone levels and lead to mental health problems such as depression, anxiety, and other mood disorders.
- Immune system: Not getting enough sleep can weaken our immune system, making us more susceptible to infection.
What Can We Do to Improve Our Sleep?
Good sleep habits can go a long way toward improving our physical and mental wellbeing. There are a few simple steps we can take to ensure we get enough quality sleep.
- Establish a regular sleep routine: Going to bed and waking up at the same time each day helps establish a regular sleep-wake cycle. This means going to bed when you are tired and setting an alarm for the same time each morning.
- Avoid stimulants: Avoiding caffeine and nicotine in the evening hours can help us fall asleep faster. Eliminating blue light from our phones, tablets, and computers can also help us relax and sleep better. Restricting our use of electronics at least an hour before bedtime is recommended.
- Create a relaxing environment: A comfortable and dark room can help promote a good night’s sleep. Setting the thermostat to a cool temperature and using blackout curtains or an eye mask can help create a sleep-friendly environment.
- Exercise: Regular exercise can promote better sleep. Exercise tones our bodies and helps us relax. Aim for at least 30 minutes of physical activity several days a week. Just make sure to avoid any forms of exercise a few hours before bedtime.
- Manage stress: Stress can have a major impact on how well we sleep. Taking part in calming activities, such as yoga or mindfulness, can help reduce stress and improve sleep quality.
Getting enough quality sleep is vital for overall health and wellbeing. Knowing the relationship between sleep and risk factors for chronic disease is important for taking steps to reduce our risk. Establishing good sleep habits can help us become healthier and increase our longevity.
