Hypersomnia means excessive sleepiness. There are many different causes, the most common in our society being inadequate sleep. This may be due to shiftwork, family demands (such as a new baby), study or social life. Other causes include sleep disorders, medication, and medical and psychiatric illnesses.
Adults with attention deficit hyperactivity disorder (ADHD) frequently suffer from sleep problems and report high levels of daytime sleepiness compared to neurotypical controls, which has detrimental effect on quality of life.
“While consistently getting less than the recommended amount of sleep has been associated with multiple adverse health outcomes, sleeping more than nine hours per night regularly may also be detrimental,” Makekau says. She says oversleeping can lead to: Increased fatigue and low energy. Decrease in immune function.
And while the occasional long sleep is generally nothing to worry about, oversleeping several days a week could be a sign that something more serious is going on.
Reasons for fatigue in females include high sleep debt, being out of sync with your circadian rhythm, your menstrual cycle and period, pregnancy, menopause, hormonal contraceptives, poor diet, lack of exercise, stress and anxiety, medication side effects, and medical conditions like thyroid issues or anemia.
Some of us are more sensitive to evening light than others, meaning our melatonin is more suppressed. This can lead to later bedtimes, a greater sleep debt, a later clock and ultimately later and longer sleeps over the weekend.
Sleeping too much, whether during the day, at night or both, can be a sign of an underlying sleep disorder. Oversleeping can have negative effects on your health and is linked to risks of many illnesses and diseases.
Why am I waking up tired? You're most likely waking up tired because of sleep inertia, the natural grogginess you get when you transition from being asleep to awake. It can take 15 minutes to two hours for sleep inertia to dissipate. Coffee, exercise, and morning light exposure can help wake you up faster.
Having a hard time waking up in the morning may be due to the natural effects of sleep inertia, your sleep habits and schedule, or sometimes point to underlying conditions.
People with ADHD frequently report having trouble waking up in the morning. For help getting out of bed, try using light therapy or plan something enjoyable for when you get out of bed, such as exercise or a nice breakfast.
A person with an 8-hour sleep need who gets 6 hours each day for 5 days builds a sleep debt of 10 hours. As sleep debt builds, brain and body functioning deteriorate. Sleep is needed to “pay down” this debt.
If you aren't feeling rested when you wake up, despite getting to sleep at least 8 hours prior, then it might not be the quantity of your sleep that's the problem. It could be your sleep quality that needs some attention. The amount of sleep you get is important, but equally important is the quality of that sleep.
Should you go back to bed if tired? Waking up tired doesn't necessarily mean you should go back to bed and sleep more, especially if you're getting the recommended 7-9 hours of sleep each night. Experiencing a little tiredness upon waking is totally normal and should subside within 15 minutes to an hour.
Sleep hygiene practices
not having a regular bedtime routine, which includes consistent sleep and wake times. taking long daytime naps. looking at phone or computer screens before going to bed. having a sleeping environment that is too hot, too bright, or too loud.
You may feel sleepy after a full night's sleep due to a medical condition. Medical conditions that can make you tired, or make it hard to meet your sleep need, include: Sleep disorders like obstructive sleep apnea, narcolepsy, and restless leg syndrome. Iron deficiency anemia.
It could be due to poor sleep quality, lifestyle factors such as stress, poor diet, and lack of exercise or an underlying health condition. It is also possible that you may not be getting enough deep sleep or REM sleep, which can leave you feeling tired even after a full night's sleep.
Lack of energy is a typical symptom for most major diseases, like heart disease, many types of cancer, autoimmune diseases such as lupus and multiple sclerosis, and anemia (too few red blood cells). Fatigue also is a common sign of depression and anxiety. And fatigue is a side effect of some medications.
Sleep deprivation lasts as long as a person isn't getting enough sleep. This can be a single night or last for weeks, months or even years. If a person has sleep deprivation, they can recover by getting sufficient quality sleep.
Sleep inertia, or wake-up grogginess, is the main reason you're unable to fully wake up in the morning or after a nap. It's a completely normal part of your sleep-wake cycle that's intensified by factors like high sleep debt and circadian misalignment (caused by sleeping in, social jetlag, and travel jet lag).
