Radiasi ponsel sering dianggap berbahaya bagi kesehatan. Tindak pencegahan pun coba dilakukan, misalnya usulan untuk memberi label level radiasi secara jelas pada ponsel yang dijual. Baru-baru ini di Kanada, anggota parlemen setempat bertekad menggolkan peraturan semacam ini.

France Gelinas, anggota parlemen wilayah Ontario, menilai peringatan radiasi yang terdapat di kertas manual ponsel sukar dilihat. Karenanya, ia mengusulkan aturan yang mengharuskan penjual ponsel dengan gamblang menampilkan level radiasi di ponsel yang mereka jual.

Jika disetujui, tiap kemasan ponsel yang dijual di Ontario bakal diberi label level radiasi. Peraturan serupa telah diterapkan di San Francisco, Amerika Serikat. Di sana, retail ponsel diminta menunjukkan level radiasi di ponsel yang mereka pasarkan.

"Rancangan undang-undang ini akan memastikan penduduk Ontario memiliki informasi yang dibutuhkan untuk memakai ponsel dengan lebih aman. Hal ini adalah bagian dari edukasi untuk memakai perangkat ini dengan seaman mungkin," tukas Gelinas.

Memang, bahaya radiasi masih diperdebatkan. Studi menyatakan radiasi ponsel menyebabkan kanker, namun studi lain membantahnya. Itu pula yang membuat Menteri Kesehatan Kanada, Margarett Best menilai pelabelan ponsel belum perlu sehingga dia siap berargumen di lembaga legislatif.

"Tidak ada risiko yang harus diperhatikan saat ini. Saya menerima saran dari para ilmuwan dan doktor," ucap Best.

Namun upaya Gelinas juga mendapat dukungan dari akademisi Trent University, Magda Havas. Menurut Havas, label level radiasi di ponsel diperlukan karena pembeli kerap tidak menyadari seberapa tingginya.

Para remaja misalnya, menghabiskan waktu memakai ponsel yang berisiko membahayakan. Havas juga mengklaim, wanita hamil tak seharusnya memakai ponsel, karena berisiko mengganggu tumbuh kembang anak. Sebuah studi University of California Los Angeles (UCLA) pernah mengambil kesimpulan ini.

"Orang-orang komplain mengalami sakit kepala dan rasa cemas yang tidak terjelaskan. Terdapat efek kesehatan dan biologis oleh radiasi ini yang tidak diketahui kebanyakan orang," pungkas Havas

Sebuah riset mengklaim ada koneksi yang jelas antara durasi pemakaian Facebook dengan gangguan pola makan. Hal ini khususnya terjadi pada para gadis remaja.

Adalah periset di University of Haifa di Israel yang coba melakukan penelitian ini. Mereka adalah Prof. Yael Letzer, Prof. Ruth Katz dan Zohar Spivak dari Social Welfare and Health Sciences Faculty. Studi melibatkan 248 remaja wanita umur 12 sampai 19 tahun.

Dikutip detikINET dari Jerusalem Post, Selasa (1/2/2011), terungkap bahwa semakin banyak waktu yang dihabiskan untuk Facebookan, risiko kena gangguan makan seperti bulimia dan anoreksia juga makin besar. Mereka berisiko memiliki citra tubuh yang buruk.

Lalu bagaimana? Masih menurut periset itu, pengawasan orang tua adalah solusinya. Jika para orang tua sering terlibat dalam kegiatan anak, risiko terkena gangguan pola makan makin rendah.

Pakar kesehatan setempat, Dr Naama Constantini menyatakan bahwa gadis yang menghabiskan banyak waktu di situs jejaring berisiko mengalami gangguan pola makan karena mungkin jadi jarang olahraga atau bersosialisasi. Menurut dia, studi di atas masih memerlukan penelitian lebih lanjut.

Bagi orang sehat, kopi bisa memberikan banyak manfaat asalkan diminum dalam jumlah yang wajar. Sebaliknya kopi juga bisa menjadi masalah jika dikonsumsi berlebihan, sebab kandungan kafein di dalamnya memiliki sejumlah efek samping.

Hingga kadar 600 mg atau sekitar 5-6 cangkir kopi, kafein belum akan memberikan efek samping pada orang sehat. Namun perlu diperhitungkan juga, sumber kafein bukan hanya kopi saja tapi meliputi teh, es krim, minuman berenergi dan bahkan obat sakit kepala.

Dikutip dari Livestrong, Selasa (7/12/2010), berikut ini beberapa efek samping jika minum kopi terlalu banyak.

1. Gelisah
Salah satu efek samping kafein bagi kesehatan jiwa adalah memicu kegelisahan. Tidak semua orang mengalami efek samping ini, namun penelitian di University of Michiganmembuktikan keparahannya bisa menyebabkan seseorang mudah tersinggung bahkan sampai tangannya gemetar.

2. Gangguan kardiovaskular
Jantung akan terasa berdebar-debar bila terlalu banyak minum kopi, karena dalam kadar tertentu kafein dapat mempengaruhi susunan saraf pusat di otak. Kafein juga dapat meningkatkan tekanan darah sehingga tidak dianjurkan untuk penderita hipertensi dan sakit jantung.

3. Sakit kepala
Beberapa jenis obat sakit kepala menggunakan campuran kafein karena dalam jumlah sedikit senyawa ini memang memiliki khasiat anti nyeri. Namun efek sebaliknya bisa muncul jika dikonsumsi terlalu banyak, misalnya minum lebih dari 2-3 cangkir kopi espresso atau 5-6 cangkir kopi biasa setiap hari.

4. Gangguan pencernaan
Perut mulas dan rasa mual sering dikeluhkan saat minum kopi terlalu banyak. Bukan karena kopinya sudah basi, tapi kafein itu sendiri memang meningkatkan produksi asam di lambung sehingga tidak dianjurkan minum kopi sebelum makan.

5. Gangguan kencing
Saat sedang kedinginan di dalam ruangan berpendingin udara, menghangatkan diri dengan minum kopi bukanlah ide yang baik. Hawa dingin saja sudah menyebabkan kencing menjadi lebih sering, ditambah efek samping kafein sebagai diuretik maka beser akan tambah parah.

6. Insomnia
Efek samping paling umum dari minum kopi terlalu banyak adalah tidak bisa tidur. Bagi remaja atau paruh baya, efek ini mungkin hanya akan memicu rasa lelah namun bisa berdampak serius bagi kesehatan kaum lanjut usia.
