Yes, that many. I bet you could think of only one … (It’s Number 3.)
1. Enjoy prefect rest.
Sleeping in the nude without too many blankets or too wintery a duvet allows for the body to arrive at the right temperature for the conditions, which in turn leads to deeper sleep, scientific studies show. Deep sleep is essential to consolidate our memory and fosters the growth hormone. It is also important in cell renewal and growth.
2. Helps to lose weight
The ‘brown’ fat we generate while asleep is the one that protects us against weight increase, which is ’caused’ by the ‘white’ fat we accumulate during the day. The ‘brown’ stuff generates heat and therefore burns off the ‘whiteys’. According to an article in Diabetes magazine, sleeping in a cold room activates the ‘brown’ fat and therefore weight loss is more rapid, compared to what happens in a hot room. The longer and deeper the sleep, the fat will have more time to work and so its weight loss properties will increase. Remember that this only happens if you sleep naked — though if the room is too cold, you’ll be waking up frequently, thus countering the benefits described here.
3. Improves your sex life
Sex therapist Denise Knowles, who counsels for Relate, says that sleeping in the nude is a good strategy for people with body image problems. Also, sleeping naked with someone increases the level of oxytocin being released and so sexual desire is increased substantially. And there are no clothes to get tangled up in…
4. Keeps your sex organs happier
Most of us wear at least two layers of clothing, even in summer. By sleeping naked you are allowing parts of your body to ‘breathe’. In men, cooler temperatures help keep sperm healthy and the reproductive organs at their best. By not wearing anything in bed, women can reduce the possibility of yeast infections. According to St. George’s Hospital gynaecologist Austin Ugwumadu, “Fungii like warm, moist, closed spaces, so it is a good idea to wear very loose clothing or nothing at all.” (We assume he meant in bed…)
5. Lowers blood pressure
Sleeping naked with someone (also naked) and being in physical contact with him/her causes sensorial nerves to send impulses to the brain, which will then release oxytocin (mentioned above). Aside from those benefits, oxytocin has a protective effect on the heart and helps to lower blood pressure. At the same time, it stimulates the immune system and lowers anxiety.
6. Helps regulate cortisol
Quoting directly from LifeHack.org: “Cortisol is a very strange chemical in the body but it can do a lot of damage. When you sleep naked, it helps keep your body temperature at the optimal ranges so your body can better create cortisol. If you sleep overheated your cortisol levels tend to stay high, even after you wake up. This can lead to increased anxiety, cravings for bad food, weight gain, and more terrible things. Sleep naked so you can keep your body temperature down and sleep well so your body can properly produce and regulate cortisol.”
7. Helps to age more slowly
Quoting from the same source: “Continuing along that same vein, keeping your sleeping environment below 21ºC every night can help your body regulate its melatonin and growth hormone levels. These chemicals help the body do things like prevent aging and are essential to good health. When you sleep in clothes, your body heats up and prevents effective use of these hormones. In other words, sleeping with clothes on makes you grow old faster.”
8. Lowers the risk of diabetes
The same study mentioned above found that sleeping in a cool room could diminish the risk of diabetes. It was observed that the level of insulin was maintained more stable when the room’s temperature was correct.
9. Good summertime sleep can be tricky
Unless you have air conditioning, chances are you will wake up drenched in sweat, so help your sweat glands to do their job by wearing nothing. Also, remember that heat rises, so it will be hotter upstairs than down.
