They say the nights need to be cool, so why do I stay awake all night no matter how much I run the air conditioner? The secret is... temperatureIt is located there. If your body temperature doesn't drop during a tropical night, you won't get deep sleep no matter how long you lie down.
Fortunately, this is not a problem that can be solved by relying solely on environmental changes. Regulate body temperature through lifestyle habitsIf you do this, you can achieve a good night's sleep even during sweltering heat. Let's explore how to design a 24-hour routine that is body temperature-friendly, from morning sunlight to your nighttime routine.
Deep sleep comes only when body temperature drops
To fall into a deep sleep Your body temperature needs to drop by about 0.5 to 1 degree. If these conditions are not met, light and deep sleep do not alternate normally, and the brain cannot recover sufficiently.
Tropical nights fundamentally hinder this reduction in body temperature. As the nighttime minimum temperature remains above 25℃ and the indoor temperature does not drop over time, our bodies are unable to lower their body temperature.
If body temperature does not drop Melatonin secretion is insufficient. Melatonin is a sleep hormone, but it is secreted in sufficient quantities only when it receives a signal of a drop in body temperature. As a result, you end up repeating only light sleep without reaching the deep sleep stage, eventually waking up in the early morning.
Creating an environment to lower body temperature at night
The most direct method is Paying attention to the bedroom environmentDo not turn the air conditioner on too low or too high; maintain it at a level that is comfortable for you.
The material of the bedding is also important. Breathable and moisture-absorbing materials like linen or bamboo are better for summer nights. You shouldn't trap heat with bedding that is too heavy.
If you toss and turn frequently while sleeping, you cannot get a deep sleep. Please also check the condition of your pillow and mattress to help you maintain a comfortable position.
Morning sunlight exposure determines the night.
Body temperature regulation begins in the morning, not the night. Exposure to sunlight for about 15 minutes within an hour of waking up resets the biological clock, and from then on Melatonin secretion is scheduled to occur 14 to 16 hours later. This is a natural sleep signal.
Exposure to morning sunlight not only generates Vitamin D but also normalizes your entire circadian rhythm. This is precisely why you should wake up at your usual time, even after staying up all night. Because morning sunlight resets everything.
Pre-sleep routine: Preparing the mind and body to be cool
You should start preparing one hour before bedtime. Keep smartphones and bright screens away. Blue light suppresses melatonin secretion, so it helps maintain a state of wakefulness.
Surprisingly, warm beverages (warm milk, green tea) are helpful. Drinking something warm causes skin blood vessels to expand and release heat, and paradoxically, lowers deep body temperature. The green tea contains L-theanine relaxes the brainIt is an amino acid.
Magnesium is also effective. In particular, magnesium glycinate is a form with high absorption rates and few side effects. It calms the sympathetic nervous system by activating GABA receptors.
Why Sleeping In on the Weekend Causes Monday Fatigue
You cannot make up for the sleep debt accumulated during the week all at once on the weekend. If you stay up late and sleep a lot on the weekend, your circadian rhythm will actually be pushed back. ‘The vicious cycle called 'Social Jetlag'It gets stuck in.
This is precisely why Sunday night insomnia leads to extreme fatigue on Monday mornings. The sustainable solution is Repeat going to bed about 30 minutes earlier than usual for a few days.That is what you do. If you gradually increase your sleep time, your circadian rhythm will not be disrupted.
The quality of sleep is key, not the amount of sleep.
Even if you lie in bed for more than 7 hours, if you cannot get deep sleep, you will be left with a heavy sense of fatigue. This is because the cleansing of waste products from the brain occurs actively only during the deep sleep stage.
The key to improving sleep quality is to create a consistent pattern where body temperature drops, melatonin is secreted, and this leads to deep sleep.
Even on a tropical night Maintaining consistency in your biological rhythm is the most important precaution.A simple habit of waking up at the same time in the morning and going to bed at a set time at night automatically helps regulate body temperature, leading to deep sleep regardless of the season.
