【優質睡眠】但願每晚都能Sleep like a baby

#除了嬰兒大人都可以有睡前儀式
#歡迎分享你的助眠法寶
#星期六放輕身心

四大助眠法寶
睡覺是人體自然的休息機制，但人越大越發覺，因為環境、健康、情緒、壓力等等原因，睡不安寧和失眠已成為常態，一覺好眠彷彿成為了奢侈品。除了病向淺中醫解決導致失眠的原因外，還可以利用一些法寶幫助睡眠。

眼罩
戴眼罩的目的最主要是遮光，所以良好的遮光性是必備條件，最基本是眼罩四邊和鼻樑位不會漏光。此外坊間還推出有附加功能的眼罩，例如可熱敷或冷敷，加入精油，甚至加入保濕、改善皮膚質素等美容功效。

耳塞
眼睛可以自行閉上，耳朵卻沒有關閉功能，所以對聲音敏感的人，想隔絕聲音的騷擾睡覺得靠耳塞了。不過有個壞處是戴耳塞令人減低警覺性，萬一有火警發生，隔音功能超級好的耳塞就會令你置身於危險之中。

抱枕
枕頭一般都枕在頭和頸之下，以承托頭顱和頸椎，漸漸發現床上應該多放幾個枕頭或抱枕，仰睡時墊在腳下有助血液回流，側睡時在腹部抱一個抱枕異常舒服，找個枕頭放在兩膝之間，更有利於放鬆腰背部肌肉，孕媽媽欠缺抱枕有時更難以入睡呢。

電風扇
睡房的溫度對睡眠有很大影響，除了利用冷氣調節溫度，電風扇是另一個經濟又有效的選擇，開電風扇可以讓房間保持通風涼爽，還能製造「白噪音」——低分貝的背景聲音頻率，大自然中類似的聲音有流水聲、海浪聲等，不少人聽著白噪音會有助入睡。

4 treasures to improve sleep quality
Sleeping is the natural rest mechanism of the human body. As people get older, they commonly have sleep issues such as insomnia and difficulty falling asleep due to factors related to environment, health, emotions and stress. Good sleep is very valuable. In addition to seeking professional advice to resolve insomnia, you can also use these gadgets to improve sleep.

Eye mask

In addition, there are some eye masks with additional functions, such as hot or cold compresses function, adding essential oils, or even adding moisturizing agents to improve skin quality and other beauty effect.

Earplug
You can close your eyes but not ears. Therefore, people who are sensitive to sound, need the earplugs to isolate from noise. However, it is harmful that the earplugs reducing your alert. If there is a fire, the earplugs with great sound insulation will put you at risk.

Body Pillow
Pillows are generally placed under the head and neck to support the skull and cervical vertebrae. Gradually it seems that there should be more pillows and body pillows on the bed. When sleeping on the back, it will help the blood to flow back by placing a pillow under the feet. When sleeping on the side, holding a pillow in the abdomen is very comfortable.

Fan
The temperature of the bedroom has a great impact on sleep. In addition to using the air conditioner to regulate the temperature, fan is another cheap and effective choice. Fans can keep the room well ventilated and cool, and can also create "white noise" - low decibel background sound frequency, similar sounds in nature are running water, sounds, waves. White noise helps many people fall asleep.

大家好，我是威狼
今天要介紹的秘境是『樹湖瀑布』
這個地方因為過去是日治村落
所以這裡種滿了許多櫻花樹
每到櫻花季的時候
整片山都是滿滿的賞櫻遊客
而這個瀑布就變得鮮少人知
這次趁著櫻花季還沒開始
就上來拍攝整個樹湖瀑布的美景
算是一個親子容易抵達的戲水勝地
位在壽豐鄉的樹湖村的「樹湖瀑布」
座落在隱密的山林之中
因在樹湖村荖山所以當地居民多稱為「荖山瀑布」
當地早期盛產豐田玉
台灣玉打響「綠色閃玉」名號
曾締造世界第一的閃玉產量
後來因為多以炸藥瘋狂開採
許多優質玉石因此遭受破壞
便宜的外國碧玉趁虛而入
大舉搶占台灣玉的全球市場
使得輝煌榮景僅十年光景
台灣玉礦屬於「角閃石」類稱為閃玉
以台灣玉為代表，加拿大、紐西蘭、西伯利亞和中國也有閃玉礦脈

『樹湖瀑布』怎麼去：
從臺9線經豐鄉豐田225.5公里處可見樹湖社區的長形水泥指標
右轉進入社區往樹湖橋（荖山橋）的方向走
沿途都有明顯標示
跟著走就會抵達樹湖瀑布
座標:23°50'45.9"N 121°27'42.8"E

大家好，我是威狼
今天要介紹的秘境是『拉克絲溪終瀑』
這集要來認真的介紹拉克絲溪終瀑
利用很多角度詮釋這個瀑布的美
空拍的畫面以水下的攝影
讓大一次擁有這個瀑布的全貌
這條溪從支流上來之後
就意外的美
兩旁是聳立的峭壁
中間的溪水又呈現碧綠深藍色
感覺像是強力的對比色
最後終瀑的地形
也讓大家不時得抬頭看看會不會有落石墜落
朋友的空拍機還被老鷹追
這裡真的很美
但一定要眼見為憑
才會知道這個秘境的壯闊

『拉克絲溪終瀑』怎麼去：
高雄市桃源區
只要上網導航路線就會抵達拉克絲溪泳池
在一直往上溯溪約莫五小時會抵達終瀑
路程約莫十公里左右
座標:23.215578, 120.865829

白噪音是人耳的可聽頻率範圍(20~2000KHZ)中，一段以相同功率持續發出的聲音。聽覺系統像是隨時待機的警報系統，當我們在睡覺時，「突然」的聲音出現，大腦查覺到這些突發的聲音產生警覺，進而影響睡眠而醒來。
白噪音在聲音的頻譜中，它從高頻到低頻平均分配。就如同一道牆，能夠屏蔽很多細節，讓你沒有意識到聲音的變化。絕對理想的白噪音是不存在的，而大自然的聲音是最接近白噪音的聲音。


ホワイトノイズは、人間の耳の可聴周波数範囲（20〜2000KHZ）で同じパワーで連続的に放出される音です。 聴覚システムは、いつでも待機している警報システムのようなものです。私たちが眠っているとき、「突然の」音が現れ、脳はこれらの突然の音を検出して警告を発し、睡眠に影響を与えて目を覚まします。
ホワイトノイズは音のスペクトルにあり、高周波から低周波まで均一に分布しています。 壁のように、細部を遮ることができるため、音の変化に気付くことはありません。 絶対に理想的なホワイトノイズは存在せず、自然の音はホワイトノイズに最も近い音です。



White noise is a sound that is continuously emitted with the same power in the audible frequency range of the human ear (20~2000KHZ). The auditory system is like an alarm system on standby at any time. When we are sleeping, "sudden" sounds appear, and the brain detects these sudden sounds to generate alertness, which affects sleep and wakes up.
White noise is in the sound spectrum, and it is evenly distributed from high frequency to low frequency. Just like a wall, it can shield a lot of details, making you unaware of the changes in sound. Absolutely ideal white noise does not exist, and the sound of nature is the sound closest to white noise.


백색 소음은 사람의 귀의 가청 주파수 범위 (20 ~ 2000KHZ)에서 동일한 파워로 지속적으로 방출되는 소리입니다. 청각 시스템은 대기 상태의 경보 시스템과 같으며, 잠을 자면 "갑작스러운"소리가 나타나고 뇌는 이러한 갑작스러운 소리를 감지하여 수면에 영향을 미치고 깨어납니다.
백색 잡음은 사운드 스펙트럼에 있으며 고주파에서 저주파로 고르게 분포됩니다. 벽과 마찬가지로 많은 세부 사항을 보호하여 소리의 변화를 인식하지 못합니다. 절대적으로 이상적인 백색 소음은 존재하지 않으며 자연의 소리는 백색 소음에 가장 가까운 소리입니다.


เสียงสีขาวเป็นเสียงที่เปล่งออกมาอย่างต่อเนื่องด้วยกำลังเดียวกันในช่วงความถี่ที่ได้ยินของหูมนุษย์ (20~2000KHZ) ระบบการได้ยินเปรียบเสมือนระบบเตือนภัยเมื่ออยู่ในโหมดเตรียมพร้อมตลอดเวลา เมื่อเราหลับ เสียง "กะทันหัน" จะปรากฏขึ้น และสมองจะตรวจจับเสียงกะทันหันเหล่านี้เพื่อสร้างความตื่นตัว ซึ่งส่งผลต่อการนอนหลับและตื่นขึ้น
สัญญาณรบกวนสีขาวอยู่ในสเปกตรัมเสียง และกระจายอย่างสม่ำเสมอจากความถี่สูงไปยังความถี่ต่ำ เช่นเดียวกับกำแพง มันสามารถปกป้องรายละเอียดได้มากมาย ทำให้คุณไม่รู้ถึงการเปลี่ยนแปลงของเสียง ไม่มีสัญญาณรบกวนสีขาวในอุดมคติอย่างแท้จริง และเสียงของธรรมชาติเป็นเสียงที่ใกล้เคียงที่สุดกับเสียงสีขาว


Tiếng ồn trắng là âm thanh được phát ra liên tục với cùng công suất trong dải tần có thể nghe được của tai người (20 ~ 2000KHZ). Hệ thống thính giác giống như một hệ thống báo động ở chế độ chờ bất cứ lúc nào, khi chúng ta đang ngủ sẽ xuất hiện những âm thanh "đột ngột", não bộ sẽ phát hiện ra những âm thanh đột ngột này để tạo ra sự tỉnh táo, ảnh hưởng đến giấc ngủ và thức giấc.
Tiếng ồn trắng nằm trong phổ âm thanh, và nó được phân bố đều từ tần số cao đến tần số thấp. Cũng giống như một bức tường, nó có thể che chắn rất nhiều chi tiết, khiến bạn không nhận biết được những thay đổi của âm thanh. Tiếng ồn trắng lý tưởng tuyệt đối không tồn tại, và âm thanh của tự nhiên là âm thanh gần nhất với tiếng ồn trắng.


White noise adalah suara yang terus menerus dipancarkan pada intensitas yang sama dalam rentang frekuensi (20~2000KHZ) yang dapat didengar oleh telinga manusia. Sistem pendengaran itu seperti sistem alarm yang selalu siaga. Saat kita tidur, akan ada suara “mendadak”. Saat otak mendeteksi suara yang tiba-tiba ini, maka akan menimbulkan kewaspadaan dan mempengaruhi tidur dan terjaga.
White noise terdistribusi secara merata dalam spektrum suara dari frekuensi tinggi ke frekuensi rendah. Sama seperti dinding, ia dapat melindungi banyak detail dan membiarkan Anda mengabaikan perubahan suara. White noise yang benar-benar ideal tidak ada, dan suara alam adalah suara yang paling dekat dengan white noise.


Il rumore bianco è un suono che viene emesso continuamente alla stessa intensità all'interno della gamma di frequenze (20~2000KHZ) che l'orecchio umano può sentire. Il sistema uditivo è come un sistema di allarme sempre in allerta.Quando dormiamo, ci sarà un suono "improvviso".Quando il cervello rileva questo suono improvviso, causerà la vigilanza e influenzerà il sonno e la veglia.
Il rumore bianco è distribuito uniformemente nello spettro sonoro dall'alta frequenza alla bassa frequenza. Proprio come un muro, può proteggere molti dettagli e permetterti di ignorare i cambiamenti nel suono. Il rumore bianco assolutamente ideale non esiste e il suono della natura è il suono più vicino al rumore bianco.


Ang puting ingay ay isang tunog na patuloy na inilalabas sa parehong lakas sa loob ng saklaw ng dalas (20 ~ 2000KHZ) na naririnig ng tainga ng tao. Ang auditory system ay tulad ng isang alarm system na laging naka-alerto. Kapag natutulog tayo, magkakaroon ng isang "biglaang" tunog. Kapag nakita ng utak ang biglaang tunog na ito, magdudulot ito ng pagkaalerto at makakaapekto sa pagtulog at paggising.
Ang puting ingay ay pantay na ipinamamahagi sa tunog ng spectrum mula sa mataas na dalas hanggang sa mababang dalas. Tulad ng isang pader, mapoprotektahan nito ang maraming mga detalye at hahayaan kang balewalain ang mga pagbabago sa tunog. Ganap na perpektong puting ingay ay hindi umiiral, at ang tunog ng kalikasan ay ang tunog na pinakamalapit sa puting ingay.
