Could more sleep help you lose weight?

 

sleep, healthSleep is a valuable commodity. And it is a whole lot more important than many of us may think. How many times have you told yourself that you can survive on very little sleep. Or maybe you have said that you have more important things to do besides sleep.  Sleep is not only important for providing you energy to get through the day. It can also impact your health in a major way if you don’t get enough.  Recent research shows that getting more sleep at night could help you lose weight and improve health.

Why is sleep so important?

Some people may try to get as much done in a day as possible without sleeping much. This may be good for your to-do list, but not for your health. When you are asleep, your body does a lot of important things that help maintain optimal health.  Without enough shut-eye, these body processes could be harmed and in turn you could increase your risk of chronic disease risk and decreased well-being. Some processes that occur when you are asleep include:

  • regulation of blood pressure and hormones
  • transfer of information from short to long term memory
  • strengthening of cognitive function
  • restoration and repair of muscle mass and tissues

Most adults should get at least seven to nine hours of sleep each night for optimal health.  I know this can be hard to do all of the time because of life’s demands. However, just like a person makes time to eat healthy and exercise, it is just as important to make time for sleeping.

Sleep and Weight Loss

A recent study looked at the impact of sleep loss on various health factors. Participants in the study had tissue and muscle samples taken after in the morning fasting state after a night of sleep loss and after a night of normal sleeping.  Study results show that those who were sleep-deprived had a down-regulation of the glycolytic pathway in skeletal muscle.

In simpler terms, those who were sleep-deprived had biological changes in their hormones like increased cortisol, reduced testosterone, and reduced growth hormone, which can all impact the body’s ability to manage a healthy weight. Also, not getting enough rest at night can reduce lean muscle mass, which in turn can negatively impact metabolism. And this in turn can affect weight management. Therefore, although this study was on the smaller side, it warrants further research on the impact of sleeping on weight management.

How to get more sleep

If you have trouble getting your seven to nine hours a day, then you may need to make some adjustments to your environment or routine. Here are a few tips to help you get more z’s.

  • Use blackout curtains: When you expose your eyes to bright lights from lamps, screens, and other sources, it can make it hard to rest.  The healthy body produces melatonin, or sleep hormone at night to help you rest. However, exposure to lights can affect the circadian rhythm in your body, and in turn delay release of melatonin. Therefore, this can make it hard to get shut-eye. Blackout curtains can block natural light that may be coming in through your windows from street lamps, neighbors windows, or car headlights.
  • Reduce screen time: Along this same line of thinking is reducing screen time. By giving your eyes a rest from the light of the screen, you can also give your mind some rest. This in turn can help you fall asleep better.
  • Don’t eat before bedtime: If you eat a large meal less than two hours before bedtime, then you could get indigestion or heartburn. This in turn could make it hard to fall asleep. The same goes for fluids. If you drink too much before bedtime, then you may have to get up frequently in the middle of the night. These bathroom visits could interrupt the REM cycle.
  • See your healthcare provider: If none of these strategies are helping you fall asleep and stay asleep, then there may be a medical issue to address. See your healthcare provider in such cases. A sleep study or physical exam could help yo find out if pain, sleep apnea, or another health condition may be making it hard for you to rest.

In the meantime, you can try a supplement like Somnova by Vita Sciences. Somnova contains natural ingredients like melatonin and L-theanine to help promote better sleep. Be sure to ask your healthcare provider before starting any new supplement regimen.

Is eight hours of sleep enough for your health?

sleep, healthWhen you don’t get enough sleep, it can affect your whole day. You may move slower, have less energy, your mind may have a hard time learning or remembering things, and you may be more easily stressed and irritated.  In turn, these factors can affect your productivity during the day and the way you get along with others. Therefore, it is super important to get enough rest at night. And just when you thought that you were reaching your health goals, a new report states that eight hours a night of rest may not be enough.

Why is sleep important?

Besides feeling better and having more energy, getting more rest at night impacts many aspects of your health. Harvard University reports that getting enough Zzz’s helps to regulate many body functions such as:

  • keeping the immune system healthy
  • muscle growth
  • tissue repair
  • protein synthesis
  • growth hormone release

Also, lack of sleep can increase risk of high blood pressure, heart disease, diabetes, depression, and obesity.  One cause of such risk is the impact of poor sleep on the circadian rhythm. Furthermore, your risk for such conditions is higher if your circadian rhythm is thrown off.  Late nights, jet lag, shift work, medications, or medical conditions can impact circadian rhythm.

New sleep recommendations

Previous recommendations say that most adults should get between 7 and 9 hours of sleep each night. However, a recent report reveals that eight hours may not be enough for optimal health. Scientists say that while in bed, only about 90-percent of that time is spent actually sleeping. Therefore, if you are in bed for eight hours, you may only be getting less than 7 hours and 12 minutes of rest.  If you go to bed for 8.5 hours, then you will be getting closer to the recommended eight hours each night.

How to get better sleep

If you have trouble even getting your eight hours of rest each night, then use the tips below to help you. If these tips still do not work, then be sure to see a qualified medical provider to help you identify the reason for your sleep troubles.

  • Meditation can help increase theta waves in the brain. These waves are the same kind that the brain produces during a nap.  If you have a hard time falling asleep, then try meditation to let your brain rest.
  • Get blackout curtains for your room to help stimulate rest. This is because the circadian rhythm is controlled largely by environmental cues like sunlight. On the other end of that spectrum, cut screen time and turn lights out by a certain time each night to get your body and brain ready for bedtime. Researchers recommend a cold, quiet environment for optimal sleep quality.
  • Try a supplement such as melatonin to help you fall asleep.  Melatonin is a natural hormone made by the body’s pineal gland. Usually, at sundown the body produces melatonin to prepare the body for rest. The body may not produce enough melatonin due to exposure to artificial light in the evening, or conditions such as mood disorders, insomnia, dementia, or stress-related conditions.  This can lead to problems falling asleep as well as low energy in waking hours. Melatonin supplements have been found to help those who may have trouble falling asleep.  Another supplement option is Somnova by Vita Sciences, which contains melatonin along with L-theanine, which both show promise for providing restful and refreshing sleep.
  • See a specialist. If you snore or have trouble breathing at night, then you may need to see a specialist. A sleeping study could help them see if there is a medical condition that is causing you to wake up tired or have trouble falling asleep at all.  Treatment, such as a CPAP machine, could help improve your breathing, and in turn help improve your sleep.
  • Manage stress: Regardless of your situation, it is important to manage stress during the day so you can rest better at night. If you have a stressful day, then your blood pressure may increase and your mind may be racing. This can make it very hard to rest. Therefore, try relaxation breathing exercises, meditation (as mentioned above), diffuse essential oils like lavender or frankincense in your home, or talk to someone that can help calm your mind.  Acupuncture, massages, or counseling sessions with a therapist are other ways you can help manage stress in your health routine, and in turn improve your sleep patterns.

Could your sleep patterns affect your mental health?

sleep, mental health, stress, anxiety, depressionSleep. Work. Eat. Repeat. Does that sound like your day, or something like it?  Sleep is often set aside as just something that a person does at the end of the day. It is often overlooked as a very important part of optimal health. A recent study found that it is so important in fact, that not getting enough sleep may increase your risk for mental health disorders.

The Importance of Sleep

The average adult needs at least 7 to 9 hours of sleep a night.  This may seem like a lot if you live a busy life which many of us do. And you may shrug it off and say, “Who needs sleep. I don’t need sleep.” The fact is that sleep is more important than you think, and without it your health could suffer.

So many things happen while you sleep. For example, at rest your body conserves energy, regulates blood pressure, and restores tissues and muscles.  Furthermore, your body regulates fluids and controls hormone levels in the body while you sleep.  Without enough sleep, your circadian rhythm can go off course. In turn, this can lead you to eat when you’re not hungry, which can lead to weight gain and increased chronic disease risk over time.

And if these weren’t enough reasons to hit the snooze button, sleep also has an impact on the immune system.  Lack of sleep can cause yo to get sick more often, which in turn could put more stress on your body and mind.

Sleep and Mental Health

A recent study looked at about 90,000 residents from the United Kingdom in regards to sleep patterns.  Study subjects between the age of 37 and 73 years wore accelerometers for 24 hours a day for 7 days.  In other words, these devices measured the rest and activity levels of participants. Those with reduced activity during the day or increased activity at night were described as having a disrupted circadian rhythm, or lower amplitude.  Comparing these patterns with questionnaires filled out by participants found links between lower amplitudes and health measures such as:

  • higher risk of unstable moods
  • lower levels of unhappiness
  • lower health satisfaction
  • greater reported loneliness

Among other findings, it is clear that this study shows that lack of sleep can greatly impact mental health measures, and in turn quality of life.

Ways to Help You Get More Sleep

There may not be enough hours in the day to get everything done.  However, it is really important to make sure sleep gets a priority on your to-do list. Therefore, if you have trouble sleeping, try some of the methods below to help.

  • Stick to a sleep schedule: Just like your other daily tasks, put sleep on your daily planner. Although it can be hard to do sometimes, setting a time to prepare for bed each night can help you develop a new healthy sleeping pattern over time.
  • Start a bedtime ritual: When it is coming close to that time of night, start a bedtime ritual that will help your body prepare for bed. Whether it is drinking a cup of herbal tea after dinner, or diffusing some lavender essential oils to relax your body, this type of ritual can reduce your risk of tossing and turning into the night. It is also helpful to reduce caffeine, sugar, and alcohol intake in the latter part of the day as well as turning off any screens during your bedtime ritual to help your eyes and mind rest.
  • Exercise each day: Any type of movement for at least 30 minutes each day can tire your body out a bit, so you can rest better in the evening. Otherwise, your body will have energy to expend with no outlet to provide it with. In turn, you will likely stay up late and have trouble sleeping. Besides that, exercise is good for keeping your body and mind healthy.
  • Take a supplement for sleep like Somnova by Vita Sciences. Somnova contains melatonin and l-theanine to help relax your mind, feel refreshed, and get more peaceful sleep. Add a sleep supplement to your bedtime routine about 30 minutes before you plan on going to sleep.
  • Visit your healthcare provider: If you have tried all of the above, or feel particularly tired upon waking, you may need to see your healthcare provider. This is because your sleep problems may be related to other conditions such as pain issues, sleep apnea, or other health conditions and should be treated under medical supervision.

Could a To-Do List Help You Get More Sleep?

sleep, anxiety, stress, list, to-do, alarmSleep is a precious commodity in your busy life. Between work, taking care of loved ones, and running errands, it is a wonder you find time to sleep at all. However, it is important to make time for sleep because of all of the health benefits adequate sleep can provide. A recent study suggests that making a to-do list may help ease your mind so you can capture more sleep.

Why Is Sleep Important?

When you sleep, your body helps to regulate many processes in the body. Blood pressure, blood glucose levels, and bodily fluids are just a few of the processes regulated during sleep. When you do not get enough sleep, you can increase your risk of high blood pressure and elevated blood glucose levels. In addition, research has found that those who consistently received less than six hours of sleep each night were more likely to have a higher body mass index than those who received at least eight hours of sleep each night. Therefore, long term lack of sleep can not only increase risk of chronic diseases such as heart disease and diabetes, but also increased obesity risk.

How Much Sleep Is Enough?

The National Sleep Foundation recommends at least seven hours of sleep each night for most adults.  Children two years of age or less require around 14 hours of sleep each day, including naps. Those between the ages of three and eighteen require around 10 hours of sleep each night. Children require more sleep to support their body’s growth and development.

Quality of sleep is just as important as quantity of sleep. Sleep quality may be low if you do not feel rested upon waking, wake up during the night, snore, or gasp for air during sleep. Sleep disorders such as sleep apnea may affect your body’s ability to get oxygen during sleep. This can impact safety during sleep and can make you feel fatigued upon waking.  If you experience interrupted sleep or wake up tired, you should see your healthcare provider for further assessment.  Pain, frequent urination, or breathing problems could prevent you from getting more sleep.

To-Do List and Sleep Research

A study in the Journal of Experimental Psychology looked at 57 Baylor University students and the effects of writing down unfinished tasks on sleep.  One group of students wrote down unfinished tasks, while the other group wrote down tasks previously completed.  All students were in a controlled environment and told to go to sleep at a set time. They were prohibited from staying up to look at phones or complete any other tasks.  Those who wrote down unfinished tasks were found to have improved sleep by use of an overnight polysomnography test.  Larger studies and observation of other age groups and individuals with sleep disorders such as insomnia will need to be done to confirm the effectiveness of such strategies.

Other Ways to Help Improve Sleep

Besides making to-do lists, here are some other ways to help you get more sleep and improve quality of sleep each night.

  • Stay on a sleep schedule each night to help your body’s clock regulate itself. It may take some time to adjust to an earlier bedtime or earlier wake time. However, over time your sleep patterns will enhance quality and quantity of sleep.
  • Exercise each day to help your body exert some energy.  Not only will exercise help improve your sleep, but it can also help manage your weight, which can in turn help you reduce risk of sleep disorders such as sleep apnea.
  • Take time to relax before sleep by engaging in meditation, relaxation breathing, and reducing screen time. The light from the screens on phones, computers, and television can interrupt the sleep-wake cycle. Adding in essential oil diffusion such as with lavender can help induce relaxation. In addition, drinking herbal teas with chamomile can help induce sleep.
  • Avoid alcohol, caffeine, cigarettes, or heavy meals before bedtime since such things can cause interrupted sleep. Caffeine and alcohol can act as a diuretic, which may cause frequent urination that can interrupt sleep. On the other hand, the nicotine from cigarettes act as a stimulant and can in turn disrupt the sleep-wake cycle.  Finally, heavy meals less than two hours before bedtime can cause indigestion and increase risk of heartburn, which can interrupt sleep.
  • Ensure your sleep environment is conducive to sleep. Every ten years, you should replace your mattresses. Every few years or so, you should also replace your pillows  to prevent exposure to allergens such as dust mites. In addition, reduced exposure to light sources in the evening can help keep your body’s rhythms in check.  You can use blackout curtains to help reduce the amount of natural light in your bedroom.
  • Add a supplement to your bedtime regimen to help you get more sleep.  Somnova by Vita Sciences contains ingredients such as melatonin and L-theanine to help promote restful sleep.

If none of these strategies are helping, then be sure to visit your healthcare provider for more sleep guidance.
