Bedtime May be a Factor in Overall Wellness


You’ve heard it plenty of times before: Adults should spend at least seven to nine hours sleeping each night, per the recommendation of the National Sleep Foundation. But does it matter when you finally call it a day and decide to head to bed? As long as you’re getting a full night’s sleep, who cares what time you choose to hit the hay, right? Not necessarily, according to research. NBC News and ABC News analyzed two different studies that showed a correlation between bedtime, heart health and mood swings.

How a Late Bedtime May Affect Your Heart
The study, presented at the American College of Cardiology’s 58th annual Scientific Session in Orlando, analyzed men who went to sleep before midnight, in comparison to those who laid down to rest after 12 a.m. These men were younger than 61 and shared information on blood pressure, cholesterol, weight, BMI and waist circumference. They also had their arteries examined and completed a questionnaire that went over sleep patterns, such as duration and bedtime.

The men who went to bed after midnight showed more signs of arterial stiffening, which is an early symptom of heart disease – even if they slept the recommended seven to nine hours.

Dr. Daniel Jones, former president of the American Heart Association, told ABC News that while these individuals were prioritizing duration of sleep, their average bedtime was the poor sleeping habit that could be to blame.

“There are a lot of potential reasons for this causal link, [such as] some of the chemicals or hormones in our body that are tied to sleep,” Jones said. “People with less deep sleep and less duration of sleep have more adrenaline release, and it’s likely that some of those hormones or chemicals could be related to the poor health of those with less healthy sleep habits.”

This holds especially true if you consider the distractions one may have from sleeping through the early morning hours. While heading to sleep at midnight and waking up at 8 a.m. means you got a full night’s sleep, your rest may have been disturbed by other family members waking up earlier, bustling traffic and other distracting noises one tends to hear in the morning when most people are getting ready for work and school.

Going to Sleep to Late May Impact Your Mood
Another study shows a significant correlation between bedtime and mood. Lead researcher Dr. Maria Paz Loayza Hidalgo of the Universidade Federal do Rio Grande do Sul in Porto Alegre selected 200 people in good health with no signs of mental illness and asked them to talk about their sleep habits and express any feelings of depression. After the assessment, the researchers found that those who went to sleep later in the evening – commonly referred to as “night owls” – were three times more likely to experience depressive symptoms than those who had earlier bedtimes. What’s alarming is that those who experienced less depressive symptoms were only heading to bed about an hour earlier than night owls.

The takeaway from this study, according to Dr. Ian Cook, associate professor of psychiatry at the University of California, Los Angeles and the director of Depression Research & Clinic Program at the university, is that even the smallest changes to your sleeping habits can alleviate mood swings and depressive symptoms.

“The study shows that even relatively subtle shifts in patterns of sleep seem to make a big difference in how people rate their mood,” he told NBC News. “That’s very intriguing stuff. Like any good study, it raises many more questions than it answers.”

The Early Bird Gets the Worm
At the end of the day, one thing still remains true: A good night’s sleep of seven to nine hours each night is critical. If you’re experiencing heart issues or mood swings, shifting your bedtime, even subtly, may help alleviate such problems. Consider this advice to lead an overall healthier lifestyle.

    I could not function without my 8 hours of sleep. Try to be in bed by about 9;30 at night. Although I do have to get up most nights to go to the restroom it doesn’t seem to affect my sound sleep. And that short little “cat nap” during the day is wonderful. I try to keep my bedroom as dark and ambient noise free as possible. It does make a difference.

    Time to work on those sleep patterns! Hallelujah Diet’s Magnsieum really helps your body to relax and get a great night’s sleep.

  3. We are hearing more and more these days about the quality of sleep we receive when we go to bed earlier as opposed to later.

    I try to get 7 to 8 hours of sleep each night, but I will admit. I feel more rested and refreshed when I do get in bed earlier.

    Hallelujah Diet Magnesium Complex helps my body wind down and relax so that I seem to fall asleep faster and get a better night’s sleep.

    I have always been one to get in the bed late and I know for sure it does make you exhausted. It is definitely time to make some changes in my sleep schedule.

    I’ve been taking magnesium in the morning. Should it be taken in the evening to aid in sleeping?

      Some people take magnesium during the day as it helps with stress. Others take it before bed to help them begin relaxing and help them have a better night’s rest. It is up to you. If I take it during the day, I feel like laying down and going to sleep. It DOES NOT feel like a sedative, though. The Hallelujah Diet Magnesium Complex is a HUGE blessing in my life. I keep several bottles on hand because I never want to run out.

  6. I like these articles, but I think links to the sources, or a list of the sources at the end, would be great. Sometimes I like to verify the information. A lot of times, people I share these articles with blow them off because the sources aren’t included.

  7. I have hear from a number of sources that it is important to go to bed before midnight, but I did not know the reasons and how it affects health. People who don’t sleep as deep or as long, have more adrenaline release. Some of those hormones or chemicals could be related to the poor health of those night owls. It is amazing that even one hour can make a difference in being less depressed. This is great advice and motivation to go to bed earlier regularity. It is surprising what a difference it can make in a positive mood. It is actually an easy thing to do to promote good health.

    This was some good information about sleep! I have a nephew that is going through some problems right now and it has alot to do with his sleep habits. The Va had told him he has depression issues and all time of the night he is up. This was confrimation to what they had told him at his doctors visit. Thanks again for good information! I will start doing some shifting myself on this too.

    Our son was badly burned in a fire about 5 years ago. Since he is not able to sleep well at all

    What might you suggest to help him. He is 47

    Thank you

      Hi Roberta,
      I am so sorry to hear about your son. Not being able to sleep is a common problem and there are many reasons why people cannot sleep.
      Before menopause, I typically slept perfectly. Within a minute of when my head hit the pillow at night, I was asleep. I pretty much slept soundly all night. UNLESS, I had something on my mind. Now, after menopause, I don’t sleep nearly as well. Hormones play a factor.
      Magnesium is a tremendous help to calm my body and mind. There are many types of magnesium. There are many herbs that can help a person sleep. Even applying lavender essential oil with a carrier oil can be helpful. There are NUMEROUS herbs that help calm, but what works for some may not help for the next. Some herbs can make a person drowsy the next morning which is not desirable.
      Which herbs or supplements has your son tried?
