What happens in our body while we sleep?
Have you ever wondered what happens in our body when we sleep? Is it resting, resetting, or maybe working at full capacity? In order to present you a dream from the inside out, we invited...
Sleep in the summer without overheating - check out Plantule's natural products
How to sleep in the heat? Here are summer sleep products – cool, airy, and natural.
It's hot. You fall asleep late and wake up early. The sheets stick to your skin, the air stagnates, and sleep—instead of restorative—is tiring. Summer nights can be beautiful, but when the temperature doesn't let up, the body doesn't rest as it should.
But sleep isn't a luxury. It's your immunity, memory, mood, metabolism—everything that helps you function with ease. So it's not about giving up on snuggling. It's about snuggling smarter.
Discover four natural Plantule products that will help you fall asleep even on the hottest nights – without overheating, without tension, without compromise.
Worth knowing:
The optimal sleep temperature is around 18–19°C. In these conditions, the body regenerates best and enters deep sleep most easily. Find out what will help you maintain a low temperature in your bedroom.
1. Buckwheat husk pillow – the best cool pillow for summer!
A buckwheat pillow is the best choice for hot nights. Thanks to its unique triangular filling structure and natural materials, it provides adequate ventilation and natural cooling, while also providing 100% support.
Now with the code: ZIMNO – 20% discount!
Why is a buckwheat husk pillow cold?
- Free air flow – buckwheat husks create space for unobstructed ventilation.
- The special shape of the scales – triangular micro-channels dissipate heat.
- Natural moisture regulation – absorbs moisture and releases it quickly.
- No heat accumulation – they do not store it like synthetic fillings.
- Natural materials – the pillow is made of 100% breathable cotton.
How to increase the cooling effect?
- Chill your pillow in the refrigerator or freezer for 15–30 minutes before bed.
- Use a breathable linen pillowcase that wicks away moisture and soothes the skin.
Fun fact:
Studies have shown that people who use buckwheat pillows experience less neck and shoulder tension.
2. Plantule Weighted Blanket
The Plantule Weighted Blanket is a weight that not only soothes but also cools. It fits snugly against the body, preventing a layer of heated air from forming beneath it. The filling, including cool glass beads, and the breathable fabrics (only linen or cotton) prevent the blanket from accumulating heat – it remains comfortable and breathable even on warmer nights.
How does a weighted blanket work?
Mechanism: Deep Pressure Stimulation – pressure that calms the body and nervous system
A weighted blanket works differently than traditional bedding. Its even, enveloping weight induces deep pressure stimulation , a natural physiological response to pressure—similar to what we experience during a hug or a pressure massage.
What happens in your body when you cover yourself with such a blanket?
-
the level of cortisol (stress hormone) decreases,
-
heart rate and blood pressure slow down – the body goes into “rest and regeneration” mode,
-
the level of serotonin (the happiness hormone) and melatonin – the sleep hormone that helps you fall asleep faster and sleep deeper – increases.
The result? A feeling of grounding, security, and peace. The body relaxes, and the mind transitions more easily from "thinking" mode to "feeling" mode and sleep.
What does the research say?
What many of us intuitively feel was also confirmed by Swedish scientists. In 2020, they published their study in the Journal of Clinical Sleep Medicine (2020) . The study involved 120 adults with chronic insomnia and mood disorders . After four weeks of daily use of a weighted blanket:
-
60% of participants experienced at least a 50% improvement in sleep quality,
-
42% achieved remission of insomnia symptoms ,
-
In the control group (light duvets) this result was only 3.6%.
One year after the study ended, 92% of people were still using the duvet , declaring lasting benefits to their sleep and well-being.
Experts from the Sleep Foundation and UCLA Health describe weighted blankets as a natural way to calm the nervous system. They are used not only for insomnia but also in therapy:
-
anxiety and chronic stress,
-
ADHD and sensory disorders,
-
PTSD and neurosensitivity.
Cooling filling for duvets
The Plantule duvet is filled with tiny glass beads and cherry pits , which, unlike synthetic fillings, do not heat up. That's why Plantule duvets:
- they are always pleasantly cool to the touch,
- they do not retain moisture, allowing the skin to breathe,
- the weight of the duvet prevents a layer of heated air from forming between the body and the duvet,
- They are made of four layers of airy linen or cotton.
3. Cooling eye pillow with flax seeds
Natural darkness and relief for the eyes
More than just a sleep aid—it's a small, restorative ritual. The Plantule Eye Pillow with Organic Flaxseed has the perfect weight to calm the nervous system and limit light exposure.
- It helps you fall asleep faster, especially in summer.
- The chilled batch brings relief from migraines and headaches.
- Linen or cotton guarantee softness to the skin and breathability.
Good to know: Sleeping in complete darkness improves melatonin production and enhances hormonal regeneration.
4. Hot water bottle with cherry pits for summer
Natural cooling compress
The Plantule linen hot water bottle with cherry seeds is a year-round friend that, when cooled, acts as a natural cooling compress.
- Soothes swelling, bruises and insect bites.
- Quickly cools the neck, feet or stomach.
- It works gently, without the risk of thermal shock.
