But the heat doesn't just make you uncomfortable: It also makes you extra sleepy. According to a new study conducted by researchers at Northwestern University, there is a reason for this, and it's likely biological.
But why does being out in the heat bring on feelings of drowsiness? The reason for this lethargy is simple: Your body is working hard to keep you cool, and this extra labor makes you feel tired, said Dr. Michele Casey, the regional medical director at Duke Health in North Carolina.
It can make it harder to stay asleep, too. Some studies suggest that the discomfort of sleeping in a hot room can cause more frequent awakenings throughout the night and can disrupt restorative rapid eye movement (REM) sleep.
Sleeping too hot
“Heat is a huge disruptor for REM sleep,” Dr. Drerup says. With the heat of the room, your body temperature will also rise, thus undoing the sleep initiation process entirely. If your bedroom temperature is above 70° F, it's too hot.
For most people, the temperature in the bedroom at night should not exceed 72 degrees Fahrenheit, and it should be even lower for people that sleep best in a cool bedroom.
Check for signs of heat exhaustion
headache. feeling sick or being sick. excessive sweating and skin becoming pale and clammy or getting a heat rash, but a change in skin colour can be harder to see on brown and black skin. cramps in the arms, legs and stomach.
You may be too exhausted even to manage your daily affairs. In most cases, there's a reason for the fatigue. It might be allergic rhinitis, anemia, depression, fibromyalgia, chronic kidney disease, liver disease, lung disease (COPD), a bacterial or viral infection, or some other health condition.
What Is An Unhealthy Room Temperature? For babies, pets, and the elderly, or for those who suffer from respiratory, lung, or heart disease, anything below 68 degrees and anything above 74 degrees for a prolonged period of time can cause serious health concerns.
For example, the ideal temperature of a living room should be around 20 to 22 degrees. This is a room for relaxing in, and where you sit for long periods of time, meaning it should be on the warmer side. Meanwhile, the best temperature for a bathroom or child's bedroom should be warmer too at 22 to 24 degrees.
The American Heritage Dictionary of the English Language identifies room temperature as around 20–22 °C (68–72 °F), while the Oxford English Dictionary states that it is "conventionally taken as about 20 °C (68 °F)".
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.
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.
It is caused by factors that can include stress from significant life events, or changes to your sleep schedule. Or it could be secondary insomnia, which is linked to health conditions like mental health issues, other sleep disorders, illness, or pain — and it can be acute or chronic.
Heat exhaustion symptoms usually go away after drinking fluids and resting in a cool place. It's essential to get to a cool place and replace fluids as soon as possible to prevent serious complications. Untreated, heatstroke can result from heat exhaustion. Heatstroke is a serious, life-threatening condition.
Waking up tired after 10 hours of sleep
Most likely, you're waking up after 10 hours of sleep because you don't know your sleep need, you're getting less sleep than you think, you've got sleep debt, or you're out of sync with your circadian rhythm. A medical condition may also be to blame.
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.
Getting good sleep, in the right amount, can make a big difference in how you feel. Too little or too much sleep can increase your perception of fatigue. And even if you get enough hours of sleep, you might find yourself dragging the next day if that sleep was interrupted by frequent awakenings or was of poor quality.
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.
“It becomes kind of like jet lag,” says Dr. Winter. “You wake up feeling kind of groggy, like you have a dull headache, maybe a bit of nausea, and lethargy—you just don't feel like doing anything.” Your best bet is to resist the urge to nod back off after you wake up.
This may vary by a few degrees from person to person, but most doctors recommend keeping the thermostat set between 60 to 68 degrees Fahrenheit (15.6 to 20 degrees Celsius) for the most comfortable sleep. Sleep Guidebook.
In general, the ideal room temperature and your home for both efficiency and comfort fall somewhere between 68° and 76°F. What should the average room temperature be in winter? In the winter, you might choose to keep your thermostat set lower around 68° in order to save energy and dollars on your next heating bill.
