2014年12月3日 日本気象協会は全国・都道府県別 2015年春の花粉(スギ・ヒノキ、北海道はシラカバ)飛散予測(第2報)を発表しました。今シーズンの花粉対策に向けてお役立て下さい。

■ 飛散開始予測

【九州から関東】

2015年の1月から2月の気温は九州から関東では平年並みか平年より高くなる予想です。この時期に気温が平年より高いと、スギ花粉の飛散開始は早くなる傾向にあります。このため、スギ花粉の飛散開始は例年より早く、2月上旬に花粉シーズンが始まる見込みです。

上図 花粉前線の数字は月日です。

オレンジ色の九州北部や四国、東海の一部は2月5日ごろ。

黄色の地域は2月10日前後の飛散開始予測です。

飛散開始とは1平方センチメートルあたり、1個以上のスギ花粉を2日以上連続して観測した場合の最初の日となります。スギ花粉は飛散開始が認められる前から、わずかな量が飛び始めますので、1月の下旬ごろにはマスクなど花粉対策を始めるとよいでしょう。

【東北】

今年も残り1ヶ月を切りました。12月3日は強い冬型の気圧配置が続き、東北や北海道では雪の降る量が増えました。二十四節気の「大雪(たいせつ)」を前に、宮城県駒ノ湯(コマノユ)では午後7時に積雪が1メートルを超えました。昨年の冬に初めて1メートを超えたのは12月8日青森県酸ヶ湯(スカユ)でした。

このまま、平年を下回る寒さが続く心配がありますが、2015年の1月から2月の気温は平年並みの見込みです。このため、スギ花粉の飛散開始は平年並みでしょう。

■ 花粉の飛ぶ数(例年比)

2015年春のスギ及びヒノキ花粉(北海道はシラカバ)の総飛散数は

九州から近畿にかけては、ほとんどの所で例年より「少ない」または「やや少ない」でしょう。

東海から東北は「例年並み」の見込みです。

北海道は例年より「やや多く」なるでしょう。

ただ、今年(2014年)の花粉の飛散数が少なかった北陸・関東甲信・東北では、2015年春の飛散数は2014年の2倍以上になる見込みです。

一方、九州、四国では飛散数は2014年に比べて「非常に少なく」、福岡では3分の1になりそうです。

Natural Allergy Relief
Chill Out(01 of10)

\"The expectations of us in a day are unreasonable,\" says Marshall. \"We work from \'can\' till \'can\'t\'; we don\'t have time to relax.\" But that constant state of stress can actually make your response to allergens worse.\n\n\"Take some time to meditate or pray or rest, whatever one does to have time for inner reflection,\" he suggests.\n \nThat includes making time for sleep. \"When you\'re fatigued, that\'s a stressor,\" he explains, creating a vicious cycle of little sleep leading to more stress leading to worse allergies, which in turn can lead to less sleep.\n\n\nFlickr photo by jmayer1129 (credit:Flickr:jmayer1129)
Leave The Outdoors Out Of Doors(02 of10)

Anything you wear or bring outside can collect pollen -- that means shoes, jackets, gloves and Fido, too. Wash his paws before he traipses pollen onto the carpet, and leave your shoes at the door.\r\n \r\nMarshall suggests stashing a clean change of clothes in the garage, or as close to your door as possible, so you can change and throw your pollen-covered duds into the wash (or at least tuck them away in a bag) as soon as possible, to decrease the amount of pollen you bring inside.\r\n\r\n\r\nFlickr photo by brookpeterson (credit:Flickr:brookpeterson)
Close The Windows(03 of10)

As tempting as it is to welcome in spring breezes, you\'ll be ushering in more than just the air. Opening windows at home and in your car allows pollen to settle on furniture, fabric, clothes and more that you might not think to clean when your symptoms set in. \r\n\r\nWindow fans can create the same problem, U.S. News reports.\r\n\r\nToo toasty with the windows closed tight? Running the air conditioning, while pricier, is a better bet if you want to stay sniffle-free, Marshall says.\r\n\r\n\r\nFlickr photo by Diego Torres Silvestre (credit:Flickr:Diego3336)
Wash Your Hair Before Bed(04 of10)

Pollen circulating in the air can easily get trapped in your tresses -- so be sure to wash it out before spreading it to your sheets and pillowcases. \r\n\r\nUse gel or mousse? Pollen is even more likely to get stuck in those locks, Health.com reports.\r\n\r\n\r\nFlickr photo by SCA Svenska Cellulosa Aktiebolaget (credit:Flickr:SCA Svenska Cellulosa Aktiebolaget)
Wash Your Sheets(05 of10)

Speaking of bedtime, it\'s a good idea to wash sheets and pillowcases more regularly than you might be used to when allergies are at their peak. Once a week is a good baseline. Just make sure the water is hot -- it\'ll kill the dust mites roosting there, which can also trigger symptoms.\r\n\r\n\r\nFlickr photo by catherine (credit:Flickr:wheat_in_your_hair)
Change Your Schedule(06 of10)

Pollen counts are higher at certain times of the day, like early in the morning, Marshall explains. Something as simple as switching your morning jog to an afternoon one can make a big difference, he says. (credit:Alamy)
Eat Right(07 of10)

There\'s little evidence to prove that eating certain foods will make you any more or less likely to have worse seasonal allergies, but maintaining a balanced diet keeps the immune system in top shape, says Marshall. \"Good nutrition, good exercise, a good healthy lifestyle will go a very long way to manage symptoms,\" he says.\r\n\r\n\r\nFlickr photo by Vegan Feast Catering (credit:Flickr:Vegan Feast Catering)
Consider Supplements(08 of10)

Herbs or nutrients taken in supplement form may provide some relief, but none has been strongly supported by definitive research, says Marshall.\r\n\r\nButterbur is one possible herb to try, and grape seed extract and quercetin, both found naturally in red wine, may also ease allergies, according to WebMD.\r\n\r\nThere\'s some indication that getting more vitamin D could also help, says Marshall, and patients have come to him asking about vitamin C, vitamin B complexes and probiotics as well, he says.\r\n\r\n\"If you are generally healthy, with no liver disease and no kidney disease, and not having to take any types of medicines on a regular basis, I never look down my nose and say it\'s a bad thing [to try supplements],\" says Marshall, but it\'s important to discuss with your doctor first.

Rinse And Repeat(09 of10)

It may sound a little gross, but, just like you washed it out of your hair, you might want to wash that pollen out of your nose, too. A simple saline rinse will do the trick. \"It\'s cheap, it\'s easy to use, it\'s not habit forming and it has virtually no side effects,\" says Marshall. \r\n\r\nBuy a bottle over the counter so you have an applicator, then refill with a homemade solution of 1/4 teaspoon salt, 1/4 teaspoon baking soda and 12 ounces of water, he says.

Consider Acupuncture(10 of10)

The traditional Chinese treatment, while maybe not your first thought for curing the sniffles, showed promise in a small 2004 study for easing symptoms, when used in conjunction with herbal medicine. (credit:Alamy)
