Be careful with incandescent bulbs which are not energy efficient at all. Instead, opt for light-emitting diode (LED) bulbs, which can also help cool your home and reduce your energy costs. Of course, when you don’t need it, turn off all lamps or ceiling lights.
Due to the summer heat wave, it is difficult to maintain an adequate body temperature to sleep better at night. Furthermore, to face the hottest days, it is important to regulate body temperature by wearing, for example, lighter fabrics or choosing cooler materials for sheets. Cotton, silk, linen and satin are best suited to control body heat and promote restful sleep.
